PMIX linking error when building --enable-static --disable-shared

[jsquyres]

When building master with --disable-shared --enable-static, it seems that a PMIX library can't be found when compiling MPI applications:

$ mpicc -g    hello_c.c   -o hello_c
/usr/bin/ld: cannot find -lpmix
collect2: error: ld returned 1 exit status
$ mpicc --showme -g hello_c.c -o hello_c
gcc -g hello_c.c -o hello_c -I/home/jsquyres/bogus/include -pthread -Wl,-rpath -Wl,/home/jsquyres/bogus/lib -Wl,--enable-new-dtags -L/home/jsquyres/bogus/lib -lmpi -lopen-rte -lopen-pal -lm -lnuma -lpciaccess -libverbs -lrdmacm -ldl -lpmix -lmunge -lutil -lrt
$ ls $bogus/lib/*pmix*
zsh: no matches found: /home/jsquyres/bogus/lib/*pmix*

I note that when I build the same way (statically) on the v2.x branch, I get a pmix library, and therefore building MPI executables succeeds:

$ ls $bogus/lib/*pmix*
/home/jsquyres/bogus/lib/libpmix.a  /home/jsquyres/bogus/lib/libpmix.la*

I believe you just need to remove that -lpmix from the args - does it then work?

Yes -- if I manually remove -lpmix from the mpicc wrapper data text file, the compilation succeeds and the application runs correctly.

Is this all that is necessary?

Should be, yes
