You'll need to set LD_LIBRARY_PATH to point to the directory with your 64-bit libgo.so. > When I said "a 32 bit archive" I meant the .a on which output of file > command looks like the following: > amandeep@s113ldom1:~/workspace$ file > /opt/go_pkgs/pkg/gccgo_solaris_sparc64/github.com/golang/libglog.a > /opt/go_pkgs/pkg/gccgo_solaris_sparc64/github.com/golang/libglog.a: > current ar archive, 32-bit symbol table > > I assumed that the error wrong ELF class: ELFCLASS32 was related to the > archive created with incorrect compiler options. Pedantically speaking, this is about the objects in the archive, not the archive itself. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
