Hello,
I have some problem to compile lam-7.2b1r10059 using PGI 5.1/5.2.
The shared library share/liblam/.libs/liblam.so.0.0.0 is not archived
correctly. So it contains no useful symbols and compilation stops at some
point later to link with liblam.so.
Then I found out pgcc compiler do not pass option (with -Wl flag) to linker
with correct order. The line below shows the command generated by pgcc to
invoke ld, which "--whole-archive" is placed after the useful obj files,
just next to "--no-whole-archive".
Although this seems to be a PGI related problem.... Because earlier post
have addressed to a PGI problem by adding "-Wl" argument.... So I think it
may be helpful to report here so we can work out the way to finally get
dynamic SSI modules to work on this fainting compiler!
Thank you very much in advanced.
