Subject: bug#8481: linking with externally generated objects

[Message part 1 (text/plain, inline)]

Hello,
 I use yasm to generate some objects and I want to include
them into a (static) library using libtool. I use automake
that in the end runs libtool as:
../../../libtool  --tag=CC   --mode=link gcc -std=gnu99
-fdiagnostics-show-option -g -O2 -maes -mpclmul   -o libintel.la
aes-x86.lo x64_do_rdtsc.o x64_iaesx64.o  -ldl -lpthread

The x64_do_rdtsc.o x64_iaesx64.o are the yasm generated files. libtool
then reports:
*** Warning: Linking the shared library libintel.la against the non-libtool
*** objects  x64_do_rdtsc.o x64_iaesx64.o is not portable!
libtool: link: rm -fr  .libs/libintel.a .libs/libintel.la
libtool: link: ar cru .libs/libintel.a .libs/aes-x86.o
libtool: link: ranlib .libs/libintel.a

and doesn't include the yasm generated files at all! This doesn't
seem correct. I attach a patch that fixes the issue for me
although I don't know whether I really fix the underlying issue.

regards,
Nikos
