Linking archive, -ipo and undefined references

fbisetti · ‎02-20-2007

Hi all,

I'd like to (i) create an archive from a module compiled with -ipo, -xP -O3 flags; (ii) link that archive to a program.

The issue. When linking, the linker complaints about "undefined references" to subroutines which are in the archive. If I turn off the -ipo, -xP flags while compiling the objs that go in the archive, everything works fine.

Questions: (1) Does this mean I can't do IPO on obj files that go in an archive and are later on linked (2) Am I trying to do something that doesn't make sense? (3) Or am I messing up the linking order? (4) Is it a compiler issue?

I am attaching a small test that reproduces the problem.

Thanks for any help,
Fabrizio
