Migrating XCode 2.0 to 3.0: GCC 4.2 incompatibility with Mac OS X 10.4 SDK

When building Cocoa projects which built and ran successfully under various XCode 2.0 versions, on my new Intel-based iMac under XCode 3.1, I keep getting the error: "GCC 4.2 is not compatible with the Mac OS X 10.4 SDK (file main.m)". What is the problem? Is there something I should change in a config file?

You're welcome.

Hello friends
I was wondering what version of xcode may be installed on a powerpc PowerBook G4 laptop with Mac OS X 10.4.11. What version would work on it? Where may I find it? I use the X11 package a lot.
Thanks a lot!

You can download it for free from the Apple Developer Connection web site, but you have to have a membership. Go to this page:
http://developer.apple.com/products/
Scroll down to the bottom of the page and the bottom right choice is the free online membership. Once you're signed up, you can log in and Download the Xcode tools. There will probably be several to choose from, including Xcode 3 and Xcode 2.5, so make sure you get the right one.

Xcode error "Command /Developer/usr/bin/gcc-4.2 failed with exit code 1 "

Hello!
This is one of my first posts on the Mac forum. I am a 13 -year-old learning to develop apps for the iPhone.
Right now I am having a really annoying error with Xcode;
I can't compile any code at all.
I tried this post in the software 101 section with no result. Sorry if a seem a bit impatient...
I am trying to use C and Objective-C command line projects....
This is the error code I get with all my projects;
Command /Developer/usr/bin/gcc-4.2 failed with exit code 1
It's not an error in the code because even if I just do a project with the code int myInt = 5;
Thanks if you can help!

Can you please post your entire program, perhaps the one that simply contains int myInt = 5; ?
When a new project is created, a main.c file is created with contents:
#include <stdio.h>
int main (int argc, const char * argv[]) {
// insert code here...
printf("Hello, World!\n");
return 0;
This should build without error by using the Build->Build menu option.
Replacing the printf line with int myInt = 5; compiles and executes properly although it does very little.

How many places do you declare calc_display? Are you perhaps creating the variable in an include file? Try posting your code here between two lines of :

How can I migrate an Aperture library from an external HDD with Mac OS Extended (Journaled, Encrypted) format?
I used to store my pictures on an external hard drive using the latest version of Aperture. Now I tried migrating my Aperture library to Photos. However, after a short moment an error message popped up telling me that "Photos was unable to make a copy of your library before preparing it. Photos does not have the necessary permissions...".
My external HDD doesn't need any permission repairs nor is the system prohibited to read from or write to it.
Thanks for any advice in advance!

My guess is that the encryption is the problem for the new app.

Welcome to Apple Support Communities
That's the classic behaviour after using Migration Assistant and that's normal.
To transfer the data from the new user account to your old user account, you can follow some steps. Here is all the information you need to do this > https://discussions.apple.com/docs/DOC-5472

I've found the problem that is my system have a incompatible file named libSystem.dylib, so I replace the file with a copy of the correct file from my colleague. That fix my problem.

I think Werner is suggesting you ask your question in the appropriate forum.
Go up 2 levels (to Community Discussion Forum) and look for the Database category. It's not that difficult to find, and you will be discussing the question with people who actually care about that kind of question.
The people who read and interact in this forum do so to discuss Documentation questions. Specifically questions about how to improve the documentaiton.

No you won't. You will need to download it from the

Migration from Photoshop Elements 8 (Windows 7 64 bit) to PE 12 (MAC)

I am planning to move from a PC Windows 7-based system to a MAC. As part of this move I will need to migrate Photoshop Elements from PE 8 in Windows to PE 12 on MAC. Back in July, I previously asked what steps would be necessary to migrate to PE 11 on MAC, but I delayed making the move (waiting for the new MacBook Pro) and will now be migrating to PE 12.
Do I still follow the same steps for a (hopefully!) smooth transition of my tagged photos and catalog? i.e., migrate from PE 8 (Windows) to PE 12 (Windows). Then from PE 12 (Windows) to PE 12 (MAC). Are there any gotchas or caveats that I should be aware of? I've read a few horror stories in various places and am nervous.
Thanks, Amy

I'm a bit slow on implementation. So far I have good news and bad news. But bottom line, I need some additional help.
First the good news: The upgrade in Windows from PE 8 to PE 12 went smoothly, with all tags and their hierarchical structure maintained. Ditto for Albums which showed up under "Local Albums."
I am now stymied with the bad news and hoping for more guidance: I just got my new MacBook last week, with my data files transfered over from my Windows PC. Unfortunately, the migration to PE 12 MAC (installed for me with the disc from the boxed version) did not make the transition smoothly. All of my tags came in under "Imported Keyword Tags," with the hierarchical structure totally flattened, and they cannot be dragged-and-dropped into a renewed structure into People, Places, and Events tags, as appropriate. Also, all of my Albums have disappeared.
I'm thinking that maybe I should restore the catalog. But when I started to do so, I was asked to choose between New or Original Location. Then, when I chose "original location" (not wanting to clutter my new hard drive with duplicates), PE 12 gave me a warning about the potential for changes to the existing file structure. So I stopped and decided to come back to the Adobe Forum for more help.
Thanks in advance! Again! Amy

Xcode Install Assistant can't be installed on Macintosh HD because Mac OS X version 10.7 or later is required.

I am a new user on a mac. I was given a mac to use for work and I need to install Ruby, Ruby on Rails. The Ruby install instructions said to install Xcode first.
The mac os x is 10.6.8. I had a problem trying to install xcode because it said the operatin system version was not compatible .. Then I found xcode version 4.2 but it then said "Xcode Install Assistant can't be installed on Macintosh HD because Mac OS X version 10.7 or later is required."

The message kind of says it all. It needs a more current version of the OS to install. Mavericks is free if your machine meets the specs for it.

I used the Migration Assistant to move data from my Time Machine to my new Mac.   Most data seems to have been transferred successfully but none of my iPhoto pictures have been transferred.
My Time Machine now shows the earliest available Back-up to be after the Migration Date.   My iPhoto pictures seem to have either been lost in the migration process or are locked in my Time Machine prior to the earliest back-up date now accessible.
Any advice on recovering my old iPhoto pictures would be greatly appreciated.

First go to iPhoto Preferences, look in both General and Advanced tabs to make sure that things are set to import from camera into iPhoto.
Then if that doesn't help, connect the camera and open Image Capture in your Applications > Utilities folder and see if you can use Image Capture to reset the import path from the camera to iPhoto.

I used migration assn't to load a Time Machine backup onto a new mac. The first TM backup after that took some time, perhaps not surprising. But the backups thereafter have all taken hours, with huge amounts of "indexing" time. Time to reload TM?

I used migration assn't to load a Time Machine backup onto a new mac. The first TM backup after that took some time, perhaps not surprising. But the backups thereafter have all taken hours, with huge amounts of "indexing" time. Time to reload TM?

Does every backup require lots of indexing? If so, the index may be damaged.
Try Repairing the backups, per #A5 in Time Machine - Troubleshooting.
If that doesn't help, see the pink box in #D2 of the same link.
