I have access to a number of different computer systems. Some are Sun Sparc (Solaris 8), some are Opterons (RHE 4), some are Mac PowerPC (OS X tiger). All have slightly different versions of gcc, but all of them are gcc 3.2 or higher, but none are higher than 4.0. I will admit that I know enough to get some stuff done, but some of this stuff is a complete mystery to me. Anyway, I have a program that is written in fortran. It has some subroutines written in C and in Ada. When I compile the program on the Suns, I must include the flag '-static' in order to get it to compile and link correctly. However, on the opterons and macs, if I include the flag '-static', it will compile, but not link. It says that it can't find some gnat library: /usr/bin/ld: cannot find -lgnat-3.4 collect2: ld returned 1 exit status gnatlink: cannot call /usr/bin/gcc If I don't give it the static flag, it links correctly and ldd shows the gnat library. I don't understand why in one instance it can find the shared library, but not when I give it the static flag. Is there some sort of different path search order when -static is used. I couldn't find any in the documentation. I also wonder if gcc is installed correctly, maybe the libraires didn't end up in some standard path? Now I don't ask to link in libgnat-3.4.so.1 so this must somehow be added in by the call to gnatlink. If I include the static flag and -L/usr/lib, which is where libgnat-3.4.so.1 is located, it still can't find it. Now I am really confused. The sys admins don't really understand this. I don't really know enough to figure out how to troubleshoot this. I guess that is what I am asking. How do I figure out what is really going on? Is there a better place to ask this question?
