Mixed up PPC and intel

Hi,
I am getting this error.
cputype (18, architecture ppc) does not match cputype (7) for specified -arch
flag: i386 (file not loaded),
And as found out it means -
I have some stuff [perhaps mpich] comiled for PPC CPU - but now you have an Intel i386 CPU. You can't mix these two.
Is there a way to undo it ? How can I remove the files that got compiled PPC CPU.
Thanks.
Regards,
Ila

Have tried doing a "Clean" or "Clean All Targets" from the Build menu?

Can PPC and Intel OS's be on the same hard drive?

I do a lot of work on Apple computers for clients.
I have made it a habit to bring firewire hard drives with OS X installed to my work locations so I can boot peoples' computers from my own, clean OS for numerous troubleshooting purposes.
I was hoping to take a big hard drive I have, partition it into 4 parts, and install 10.4 Intel, 10.4 PPC, 10.5 Intel, and 10.5 PPC.
But after I installed the PPC 10.4, I went to my macbook pro and tried to install 10.5 Intel.....and it wouldn't let me!
So now I am learning about the Apple Partition Map format for a drive versus the GUID format and that basically one is for PPC and the other for Intel.
But I would like to know if there is any way to format a drive in such a way that I can indeed install PPC and Intel version of an OS onto one physical drive in separate partitions???
anyone?

It's not intuitive but it's possible. You must set up your external drive using the APT partition map. Install the PPC version of OS X on one partition. Now here's the trick: You must install an Intel version of Leopard on a drive that has been partitioned using GPT. Then clone that installed version to another partition the external drive that now has the PPC version of Leopard. You now have a PPC version of Leopard on one partition and in Intel version on the other partition. You will find you can boot an Intel Mac from that partition even though the drive is partitioned APT.
The problem is that Leopard will not allow itself to be installed on an APT partitioned drive. But an Intel version of Leopard will work just fine from an APT partitioned drive.

Difference in sound between Logic on PPC and Intel (64 Bit)

hi,
I'm using PPC for Logic Pro. Is there any difference in sound between using logic pro on PPC and running it on Intel Macs. I'm not good in tecnical things, but someone told me, Logic would sound better on Intel based Macs, because the system is 64 bit instead of 32 bit on PPC. Is that true? Any experiences?
Thanx,
grooveX

There are no differences!
the "sound quality" is stryctly relted with the Audio equipment.
(the new Intel Xeon processors are faster than PPC... in 2008... obviously... but in 2003/4/5 PPC G5 was much faster than same year 2003 Intel Xeon release
If you work with DAE TDM HD accell in PPC or on Intel the sound will be the same...
obviosly if some update shoot down the compatibilty with PPC side you will cannot use the future upgrades...
if you use a Motu 828 Mk3 the sound will be great... and same as ppc or Intel or Windows and Linux
(but Logic works on Mac... PPC and Intel... is the same... logic is the master of the sound).
Anyway... I think the analog recording studio in the 1970 1990 gives you a super great sound... in some cases the analog recording studio sonds much better that digital studios..
I'm talking about a simple example.. the audio frequency are from 20 to 20.000 HZ... the music quality... (artistically) is not related with the quality of the machine that you use for make it....
I suggest you not follow the mode ... and run to buy the last model .. most often are money thrown to the wind.
if you buy a good new interface.... you are in the rigth way...
but the very important thing is:
MAKE YOUR MUSIC AND DON'T MATTER ABOUT these unnecessary competitions ... is only useful to those who sells computer!
I know people that doing good music with old G4 ...
...music with highest quality ...
is not the machine that makes the music .... Only MEN can obtain a piece of art ... even using dirt!

OS X 10.4.x on PPC and Intel having problems with Card Readers

Hello,
I am in charge of a school district running about 75 client macs, all PPC G5 and Intel mixed. I have been having reports that the Lexar card readers for the digital photography lab sometimes do not auto-mount the media that is inserted into them. Apple System Profiler detects the card reader, but when the card is stuck into the reader it does not appear in finder at all to retrieve the files.
Upon testing, a reboot usually alleviates the problem, but the teachers feel that the interuption in class and productivity time for a reboot is unacceptable.
I have the user accounts managed through Workgroup Manager on my Xserve, and I have it set so that they have access to auto-mount media (unless I'm missing a setting somewhere. But i'd think if the setting was off, the reboot wouldn't matter and it wouldn't fix the issue).
At anyrate, my question is has anyone else expierenced problems with card readers and auto-mounting the media in OS X? How about in a multi-user environment. Does anyone have any suggestions? All are welcome.
Thanks so much for your time.

Since the latest update Mac OS X 10.4.9, my USB card readers have stopped working. The media is recocognized, but the transfer rate is so slow I could manually write the binary.
There were no issues prior to this update, and card readers work on machines NOT updated.

External hard drive for both a PPC and Intel Mac?

I have 2 LaCie Hard Drives (500GB & 750GB) that I'd like to use for backing up my 2 laptops and for storing photo and music files.
When I got the MacBook Pro, I partitioned the 500GB drive into 3 volumes and used SuperDuper! to make "bootable" copies of the MBP on one volume, theiBook on one volume, and put photo files on the third. I don't know/can't remember how I dealt with the directions below from Disk Utility and I fear I may have done the impossible or at least done the wrong thing.
"If you will use a volume as a Mac OS X startup disk, click Options and choose the appropriate partition scheme. To use a volume to start up an Intel-based Mac, choose the GUID partition scheme. To use a volume to start up a PowerPC-based Mac, choose the Apple partition scheme."
As I ask these questions, I find myself getting tongue-tied so please bear with me and read on...
#1 - Is it *even possible* to do what I want and have the bootable copies of both of these laptops on the same HD since one is PPC and the other Intel? If the answer if yes, it's OK then the rest of this is moot.
#2 - I can easily delete one or the other laptop backup from the 500 LaCie and put it on the virgin 750 and partiton it - problem is, is there a way to know how I partitioned the 500 HD so I won't have to redo it -I don't want to have to recopy the thousands of photo files already on the HD. If I knew how it was partitioned - Intel or PPC - I could just delete the appropriate laptop and move it to the other LaCie, assuming I have to.
#3 - And, is it possible to use a drive that has been partitioned for PPC or Intel with the other type computer - will I be able to access the jpg photo files from both the MBP and my G4 both of which are Tiger no matter which way the HD is partitioned? Now I as able to do this, but as I said, I don't remember which way I partitioned the HD - all I remember is that I did choose to include OS 9 drivers since I still use Classic and OS 9 on the G4. ( I have yet another LaCie that I use exclusively to back up my G4 and it is not part of this issue)
Mrs H

So "To use a volume to start up a PowerPC-based Mac, choose the Apple partition scheme." really means it will work for my Intel MBP too?
Yes.
Is there a way to tell if that is what I already choose?
Select the existing drive in the Disk Utility and find the Partition Map Scheme text at the bottom of the window.

GUID or APM for PPC and Intel Macs

Apple Article 306932 states
Click the Options button.
Select a new partition scheme:
Use "Apple Partition Map" partition scheme if the disk will be used with Time Machine and a PowerPC-based Mac.
Use "GUID" partition scheme if the disk will be used with Time Machine and a Intel-based Mac.
So, I have a PB G4 (PPC) and a Mac Book Pro (Intel), both of which I want to use with TM to one external drive.
So, which partition scheme should I use?

I suggest that you take a look at the following links as they may provide you with an answer :

Partition scheme for PPC and Intel

I have a G4 mini and an Intel Macbook and one USB harddrive to back them up with time machine. I think I'll connect the drive to the mini and share the drive so I can back up the Macbook.
Anyway, I was reading:
http://docs.info.apple.com/article.html?artnum=306932
and it says to choose the "Apple Partition Map" scheme for use with PPC and "GUID" for use with Intel. Anyway, I was wondering what I should choose when I need to use it with both processor types.
Thanks for any advice!

Oops, it seems that a similar message appeared while I was posting this one, so I think I might as well just follow the discussion on that thread, sorry for the duplicate.

Erasing Time Machine hard drive after formatting for both PPC and Intel

Ok, I made a mistake. First I formatted a Western Digital 500 gig hard drive for both my wife's PPC G4 laptop and my own Intel MBP laptop, so we could both use Leopard's Time Machine for backing up to the same drive. That wasn't my mistake though, it's been working fine. I formatted my partition using the GUID option and hers using the Apple Partition Map option (I think that's what they are called, I'm going from memory).
Here's my mistake: I needed some extra space to store some files and read that I could Re-Partition the drive without erasing anything using Disk Utility. Sounded great. I first tried to partition my wife's partition, since she had more extra space, but then I realized that was a bad idea since I had formatted her partition with using the Apple Partition Map, so I stopped and then tried to Re-Partition my side. It worked for about an hour: my Time Machine backup drive appeared, my new partition appeared, but then... her partition disappeared! Usually whenever one of us plugs in the hard drive using the firewire cable, both partitions appear, Time Machine Goes to work, and that's that. When we need to disconnect from the drive we have to eject both drives, but no big deal. Now her drive isn't appearing.
So... I tried to repair it, no good. Tried to erase both her partition and mine (to just start over): no good. I can't do anything to either of these partitions now, from either computer. Tried everything I could think of in Disk Utility, from both computers. Won't erase, won't re-partition. Not a hardware issue: it all started when I did this stupid Re-Partition. Help!!!!
I want to erase the drive and start over. Can anyone advise??

Jasonmo,
First, let's talk about the various partition schemes. A partition scheme applies to the entire drive. Specifically, these are different maps written to the drive, within which volumes are created. As such, this is an either/or thing; your drive is partitioned using either the GUID Scheme, or the Apple Scheme, not both.
"Live" partitioning or re-sizing of existing volumes is supported only under the GUID Partition Scheme. If the drive wasn't using this scheme, you would not be able to re-size as you were attempting to do. Even re-sizing under the GUID scheme requires that the drive's maps and directory structures be in very good shape, if it is to work without hitch.
Are you absolutely certain that there isn't some physical problem with the drive, or with its interface (cables and such)? If it is operating normally, you should be able to re-partition it without problems. In DIsk Utility, select the drive (not a named volume that will appear indented underneath), then click the "Partition" tab. If you wish to be able to re-size volumes later, you must choose the GUID scheme from the "Options..." dialogue sheet. Set appropriate sizes for the volumes, then click "Apply." Doing so will destroy all current volumes and data on the drive.

Floating point formats: Java/C/C++, PPC and Intel platforms

Hi everyone
Where can I find out about the various bit formats used for 32 bit floating numbers in Java and C/C++ for both Mac hardware platforms?
I'm developing a Java audio application which needs to convert vast quantities of variable width integer audio samples to canonical float audio format. I've discovered that a floating point divide by the maximum integer value gives the correct answer but takes too much processor time, so I'm trying out bit-twiddling in C via JNI to carve out my own floating point bit patterns. This is very fast, however, I need to take into account the various float formats used on the different platforms so my app can be universal. Can anyone point me to the information?
Thanks in advance.
Bob

I am not sure that Rosetta floating point works the same as PPC floating point. I was using RealBasic (a PPC basic compiler) and moved one of the my compiled applications to a MacBook Pro and floating point comparisons that had been exact on the PPC stopped working under Rosetta. I changed the code to do an approximate comparison (i.e. abs(a -b) < tolerance) and this fixed things.
I reported the problem to the RealBasic people and thought nothing more of it until I fired up Adobe's InDesign and not being used to working with picas, changed the units of measurement to inches. The default letter paper size was suddenly 8.5000500050005 inches instead of the more usual 8.5! This was not a big problem, but it appears that all of InDesign's page math is running into some kind of rounding errors.
The floating point format is almost certainly IEEE, and I cannot imagine Rosetta doing anything other than using native hardware Intel floating point. On the other hand, there is a subtle difference in behavior.
I am posting this here as a follow up, but I am also going to post this as a proper question in the forum. If you have to delete one or the other of these duplicate posts, please zap the reply, not the question.

Internet Sharing for PPC and Intel based Macs

I have OSX 10.4 Server running with NAT and DHCP enabled. The internet is accessed through a wired connection, and 2 Powerbooks(PPC based) and an Intel iMac and MacBook connected to the server via Airport. The wireless signal is WEP protected, and the Intel based Macs can connect to the wireless network, recieve a good IP address and access the internet. These two connected computers can be seen on the Server Admin DHCP Clients tab.
My problem is with the PPC based Mac, the 2 PowerBooks. Those computers can connect to the wirless network, but they get an invalid IP address. Not only is the IP invalid, so is the Subnet Mask.
All computers are running 10.4.7, and all installed from the Combo Updater.
Any suggestions?

We're having the same problem here!
Rarely we manage to get the right IP address assigned to one PPC machine by playing with various network settings but we didn't found a reliable way to get the PPC machines always working.
This is really strange... any suggestion is appreciated.

Nodes - PPC and Intel

Greetings.
Anybody out there noticing an appreciable difference/benefit when noding newer Mac Pros (8 core) running LP8 that are noded to legacy G5s PPCs (say dual 1.8mHz).
In other words: is it worth hanging on to our older PPCs for added performance and nodeing them to newer Intel hardware (specifically with regard to LP8).
_*Anybody have specifics, benchmarks, statistics, etc.?*_
In advance, thank you.

It's not intuitive but it's possible. You must set up your external drive using the APT partition map. Install the PPC version of OS X on one partition. Now here's the trick: You must install an Intel version of Leopard on a drive that has been partitioned using GPT. Then clone that installed version to another partition the external drive that now has the PPC version of Leopard. You now have a PPC version of Leopard on one partition and in Intel version on the other partition. You will find you can boot an Intel Mac from that partition even though the drive is partitioned APT.
The problem is that Leopard will not allow itself to be installed on an APT partitioned drive. But an Intel version of Leopard will work just fine from an APT partitioned drive.

GUID or APM? For two different Mac OS X - PPC and Intel?

I need to backup two Mac OS X systems for just in case situations. These two systems have to be bootable with the respectively Macs.
I intend to partition a spare FireWire hard disk into two partitions.
First partition will be for an Intel-based MacBook Pro.
Second partition will be for a PPC-based Mac mini.
Should I partition the hard disk either in GUID or APM? I know GUID is for Intel-based Macs and APM is the older partitioning scheme. I guess I can't have one GUID partition and the other APM.
After partition, I will use Disk Utility's Restore feature to clone my old Mac OS X systems to the respective partitions. And hope they will boot with my two Macs.
Help? Advice anyone?

Is Target Mode universal across PPC and Intel Macs?

A new Mac Mini Server (2010) finds drives from recent Intel MBP, iMac and MacPro computers booted into target mode but does not see anything from a titanium Powermac G4 in target mode. Identical cabling: Mini > Firewire 800/400 adapter > firewire 400 cable > Powerbook.
Any thoughts or references to documentation?
Thanks,
John

Thanks for all suggestions!
The PowerBook G4 is the 867 (Ti) model: ATA drives. The host Mini (2010 Server) sees nothing when attached to the PB booted into Target mode.
The KB article that was suggested (HT1661) lists computers that support Target Mode including "Powerbook G4 (all models)." But under Requirements it also says "FireWire 2.3.3 or later." In System Profiler on the G4 on the Software>Extensions screen it shows me "IOFireWireFamily version 2.2.5." Is that the right place to look? There's also IOFireWireAVC and IOFireWireIP, both with version numbers like 1.x.x. If the Firewire version is too low, how does that jibe with the statement that "Powerbook G4 (all models)" are supported?

Building InDesign CS4 plug-ins once for both MAC PPC and MAC Intel

Hi All,
I would like to know if there is a possibility to build the indesign plugins once for both PPC and Intel on MAC. Right now I'm forced to build my plugins twice: on the PPC machine and on the Intel Machine.
I tried to build the SDK example Basic Persist Interface on my MAC Intel machine and then i placed it on my MAC PPC and it failed to load.
is there any configuration I need to specify so the XCode linker will link for both machines?
I'm using:
InDesign CS4
Leopard 10.5.8
XCode 3.0
Architectures: i386
Valid Architectures: ppc67 ppc7400 ppc 970 i386 x86_64 ppc
Instruction Sheduling Power pc G4
thanks,
Itamar

Please advise - new iMac i7, old iMac G5 PPC, and migration assistant

I just received my new iMac i7 and am getting ready to use Migration Assistant. However, I have some questions:
The logic board on my old machine died, so I pulled out the Hard Drive and put it in an enclosure. This is what I will be using to make the Migration.
My old machine was a PPC, and it was running 10.4.11.
I have read various posts for and against using MA to transfer files and user data between PPC and Intel machines.
I was planning on letting MA transfer everything, and going from there.
Doing it this way, is there really room for MA messing up my new machine?
I have thousands of emails, 80GB of music, 5000 photos, tons of bookmarks, and lots of documents that I'd like to transfer.
I would like NOT to do a manual migration.
Can I safely use MA?
Thanks for all help and advice!

Users migrates files in your user home folder. This is the folder named as your user account short name and has the house icon if you are logged into that user account. So as long as your user files such as Music files, Word documents, etc. are stored in that user home folder, they will be migrated. If you created a folder structure outside the user home folder for some reason, selecting Users will not migrate those folders (because they are not located in your user home folder).
Applications will migrate things in the Applications folder (minus Apple's apps that are already installed). It probably also transfers application-related files at other locations, based on what Migration Assistant knows about and is scripted to do.
Settings will transfer settings from the old Mac to the new Mac, such as hardware and network settings. This is not user data. Since your old Mac is PowerPC, you should set up your Intel iMac independently.
+Other files and folders...+ will transfer files and folders outside your user home folder that Migration Assistant treats as potentially being or having user data. For example, if you had folder called Stuff at the top level of old Macs hard drive volume, that would get transferred. As long as your user data is stored in your user home folder (the house icon), all this will do is transfer random things you do not need cluttering your new iMac. If you know of something that was not stored in your user home folder that did not get transferred, since your old iMac's hard drive is connected as an external drive, you can just use Finder to locate and copy over that something manually.
