Linker cannot find libcx

Question

Hi,
I am trying to run a testcase on a Solaris 64 bit machine using a 64 bit Forte 6u1 compiler. This testcase runs grand when run on a 32 bit machine, but when it tries to link on the 64 bit machine, the following error comes up;
ld: fatal: library -lcx: not found
I understand that libcx is a 32 bit library and that there is not 64 bit equivalent for it and that libc should be used instead. My problem is that I cant find where libcx is being referenced. I have looked through all the flags in the relevant makefile and the chain of relevant makefiles that are included but cannot find anywhere what this library is referenced. The link line that fails is:
/vob/tools_SunOS/FORTE6U1_64/WS6U1/bin/CC -o stockmarket_client ObjectGroupDemoC.o NamingServiceC.o LoadBalancingC.o stockmarket_client.o common.o -L/vob//Solaris64_2.8_SC6.1/rel/lib -L/Naming/src -L/vob/demos_3.0/demolib/cxx -Bdynamic -lorbix -lITtls -Bdynamic -lITns -Bstatic -ldemo -Bdynamic -L/usr/lib/sparcv9/ -lnsl -lsocket
Does anyone have any ideas where else it could be included or of any flags that should be included / precluded to stop this occurring?
Thanks

FD6u1 is obsolete and no longer supported. You should update to Sun Studio 11, which is free. You can get it here:
http://developers.sun.com/sunstudio/
As long as you don't need to run on versions of Solaris older than Solaris 8, there is no reason to continue using that old product.
You cannot mix 32-bit and 64-bit binaries in the same program. You can compile and link a 32-bit program and run it on a 64-bit Solaris kernel, but you can't link it to the 64-bit libraries on Solaris.
When compiling or linking a 64-bit binary on SPARC Solaris, use the option -xarch=v9 (or v9plusa or v9plusb). This option causes the CC driver to generate 64-bit code and link 64-bit libraries.
You are attempting to link 64-bit libraries by the use of -L options, which will not work. Never use -L options that point into the compiler installation area or into /usr/lib. If you think you need to use such options, it is because you are doing something else wrong. In this case, omitting -xarch=v9 is the "something else".
When you use a correct command line to link 64-bit objects, you will find there is no longer a reference to libcx. BTW, libcx is obsolete, and current compilers to not generate references to it.
