Here's yet another similar type of error I'm getting on AIX. I
basically compiled and installed nlopt in a custom location via
--prefix. Now, when I go to R to compile a package (nloptR) that
links to nlopt, the linking works, but when R tries to load the shared
object, it gets 'symbol not found'. Again, this doesn't error out in
other platforms. Is there anything I can do with GCC on AIX to fix
this? Thanks.
checking for nlopt.h... yes
configure: Suitable NLopt library found.
