These paths seem likely. You also need to ensure that you install the 64-bit version of the library (since it's probably a different package to the 32-bit version). >Normally Solaris knows the 64-bit versions of libraries are in 'sparcv9' or >'amd64' directories, but in this case, I believe the fact we are specifying an >absolute path to a file, we should specify the 64-bit library on 64-bit builds. This is correct. The linker magic that looks in the sparcv9 or amd64 subdirectories when linking 64-bit code only applies to system directories. If you explicitly specify a linker directory (via -L/-rpath) or pass a library by pathname then you have to specify the pathname of the wanted version of the library. I find this a PITA. As I've mentioned before, and despite claims otherwise, Solaris behaves very much a 32-bit OS with 64-bit support tacked on. -- Peter Jeremy
