When I have LDFLAGS set to "-m64" I get this message, ld: unrecognised emulation mode: 64 Supported emulations: elf32ppclinux elf32ppc elf32ppcsim elf64alpha alpha armelf_linux armelf hppalinux elf_i386 i386linux elf64_ia64 m68kelf m68klinux elf64ppc elf_s390 elf64_s390 elf32_sparc sparclinux elf64_sparc sun4 elf_x86_64 ppcmacos make[3]: *** [/home/trip3/pvfs-2.6.0/src/kernel/linux-2.6/pvfs2.o] Error 1 make[2]: *** [_module_/home/trip3/pvfs-2.6.0/src/kernel/linux-2.6] Error 2 make[1]: *** [default] Error 2 make: *** [just_kmod] Error 2
I did not have any 'lib/libpvfs2-threaded.*' files created after the compilation so I guess the configure script somehow was set not to build threaded libraries but ' pvfs2-client-core-threaded' has dependencies for those libraries. After a make distclean I searched for any residual *.a or *.so files in the build tree but none existed. Here are the steps I took to get it to compile and link but I have not attempted to insmod the module until the threaded libraries issue is resolved. # make distclean # find . -name "*.a" --no results # ./configure --with-kernel=/usr/src/linux-2.6.16.21-0.25 --without-openssl --disable-server # make kmod .. /usr/bin/ld: cannot find -lpvfs2-threaded collect2: ld returned 1 exit status make: *** [src/apps/kernel/linux/pvfs2-client-core-threaded] Error 1 # make kmod V=1 .. gcc -m64 -o src/apps/kernel/linux/pvfs2-client-core-threaded -L /home/trip3/pvfs-2.6.0/lib -rdynamic src/apps/kernel/linux/pvfs2-client-core.o -lpvfs2-threaded -lpthread /usr/bin/ld: cannot find -lpvfs2-threaded collect2: ld returned 1 exit status make: *** [src/apps/kernel/linux/pvfs2-client-core-threaded] Error 1 At this point I replaced '-lpvfs2-threaded' with '-lpvfs2' and reissued the gcc command, # gcc -m64 -o src/apps/kernel/linux/pvfs2-client-core-threaded -L /home/trip3/pvfs-2.6.0/lib -rdynamic src/apps/kernel/linux/pvfs2-client-core.o -lpvfs2 -lpthread #make kmod Building modules, stage 2.
