Compile flags disturbe building of package [solved]

Question

Hi.
I have my compile flags set in makepkg.conf, and every package was building ok till now. Yesterday I tryed to build Sphinx with yaourt, but the build stoped when building libsphinxclient. I think it has something to do with the compiler flags set in makepkg.conf. When it builds with yaourt:
/bin/sh ./libtool --mode=compile --tag=CC gcc -DHAVE_CONFIG_H -I. -I. -I. -march=athlon64 -O2 -pipe -c -o sphinxclient.lo sphinxclient.c
and the build stops after that (this does not give the error, but it doesn't build some libraries needed afterwards).
When I build it manually, the command differs:
/bin/sh ./libtool --mode=compile --tag=CC gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c -o sphinxclient.lo sphinxclient.c
The ./configure for the manuall build is the same as from the PKGBUILD
This is the whole build process for libsphinxclient from yaourt:
make[1]: Entering directory `/tmp/yaourt-tmp-krt/aur-sphinx/sphinx/src/sphinx-0.9.8.1/api/libsphinxclient'
/bin/sh ./libtool --mode=compile --tag=CC gcc -DHAVE_CONFIG_H -I. -I. -I. -march=athlon64 -O2 -pipe -c -o sphinxclient.lo sphinxclient.c

The build of libsphinxclient manually:

/bin/sh ./libtool --mode=link --tag=CC gcc -g -O2 -o test test.o .libs/libsphinxclient.a
gcc -g -O2 -o test test.o .libs/libsphinxclient.a
make[1]: Leaving directory `/home/krt/Desktop/sphinx-0.9.8.1/api/libsphinxclient'
In yaourt a whole block of output is skipped after the second line, and it continues with the compiling of test.c:
gcc -DHAVE_CONFIG_H -I. -I. -I. -march=athlon64 -O2 -pipe -c test.c
Since test.c need's libsphinxclient.a and it doesn't exist (it would have been compiled in the skiped part (like in the manually compiled section)), the build isn't successful.
NOTE: I don't know much about compiling, it's just my observation.
Why doesn't it work with the compile flags set?

Answer 1

Well, it appears that the package doesn't build with multiple concurrent build jobs.
Try adding the following above the line beginning with "./configure" and see if it then builds correctly:
export MAKEFLAGS="-j1"
On a side note, I've found -j2 to work perfectly for dual core systems. I've definitely seen -j(number of cores)+1 being suggested elsewhere, but I can't see why -j(number of cores) isn't equally suitable or even more correct.
