Unable to build a shared library on HP-UX 11.22

[sachin myneni]

Hello,

I am trying to port my shared library to HP-UX 11.22 running on Itanium2. The linker is unable to find the libraries that I build *and* have in the correct place!
I seem to have the correct link line :)


......................................................
Linking executable nu80d_HP-UX_42_ia64.sl

Fatal error.

The library libnumerflib_HP-UX_ia64.a does exist in 'nu_libs' so I am not sure why ld doesn't find it. I also tried not having -Wl, ahead of each -L/path/...but that didn't help either.

The objects in libnumerflib_HP-UX_ia64.a are of the following type:
y12mdf.o: ELF-64 relocatable object file - IA64

Any help is most appreciated.

You are compiling with '-Wl,-ashared', thus linker only searches for shared libraries and you have archive library (.a).

[Amit Agarwal_1]

As said by Ermin using -Wl,-ashared forces search for shared library only. Replace it with -Wl,-ashared_archive, to search in shared libraries and then on failure search in archive libraries.

man ld...for more information
