[gmx-users] AIX XLC Gromacs-5.1-rc1. Undefined reference. Underscore issue.

[Carlos Aguni]

Helo guys!

I'm trying to compile Gromacs-5.1-rc1 with XLC 13.1.2 & ESSL 5.3 and I'm
facing
an undefined reference error.
Here's what I got:

I think that's an underscore problem. Because ESSL has those functions but
the

flags responsible to solve that (-qextname -qnoextname) isn't working:

$ objdump -x /usr/lib/libessl.so | grep dlaev2

0000000000000000 l    df *ABS* 0000000000000000
/home/essl/src/work/dlaev2.f

0000000000aa67a0 l     F .text 000000000000023c              0x60 dlaev2

$ objdump -x /usr/lib/libessl.so | grep dlacpy

0000000000a9a0e0 l     F .text 00000000000003b0              0x60 dlacpy


Can anyone help?


Thanks in advance!

Carlos.
