Well, okapi (Gentoo) doesn't like it:
configure:29191: checking for libperl
configure:29217: icc -o conftest -O3 -xSSSE3 -parallel -ip -mp1 -fno-strict-aliasing -g
-I/usr/lib64/perl5/5.12.4/x86_64-linux/CORE -D_GNU_SOURCE -I/usr/include/libxml2 -I/usr/include/et conftest.c
-Wl,-O1-Wl,--as-needed -L/usr/lib64/perl5/5.12.4/x86_64-linux/CORE -lperl -lnsl -ldl -lm -lcrypt -lutil -lc -lxslt
-lxml2-lssl -lcrypto -lkrb5 -lz -lreadline -lcrypt -lm >&5
ld: conftest: hidden symbol `pthread_atfork' in /usr/lib64/libpthread_nonshared.a(pthread_atfork.oS) is referenced by
DSO
ld: final link failed: Bad value
The previous successful build on that box shows that plperl was linked
like this without any error:
icc -O3 -xSSSE3 -parallel -ip -mp1 -fno-strict-aliasing -g -fpic -shared -o plperl.so plperl.o SPI.o Util.o
-L../../../src/port -Wl,-rpath,'/usr/lib64/perl5/5.12.4/x86_64-linux/CORE',--enable-new-dtags -Wl,-O1 -Wl,--as-needed
-L/usr/lib64/perl5/5.12.4/x86_64-linux/CORE-lperl -lnsl -ldl -lm -lcrypt -lutil -lc
The best guess I can come up with is that this box is only able to link
libperl.so into a shared library, ie the "-fpic -shared" part of the
recipe is critical. If so, this idea is a failure and we're gonna have
to remove the link test, because there is no way I'm going to try to put
enough smarts into the configure script to do a shared-library link
correctly.
However, I don't know Gentoo at all, and it may be there's some other
explanation that we could cope with more readily. Thoughts?
