Hi Jan, Cyril,
> I tested v2 as far back as RHEL6.2, ACK.
Jan, have you tested out of tree build?
Still failing [1], mostly for out-of-tree builds [2]:
make: Entering directory '/usr/src/ltp-build'
make -C "lib" \
-f "/usr/src/ltp/lib/Makefile" all
make -C "libs" \
-f "/usr/src/ltp/libs/Makefile" all
make[1]: Entering directory '/usr/src/ltp-build/lib'
mkdir -m 00755 -p "newlib_tests"
make[1]: Entering directory '/usr/src/ltp-build'
make[1]: *** libs: No such file or directory. Stop.
make[1]: Leaving directory '/usr/src/ltp-build'
/usr/src/ltp/Makefile:114: recipe for target 'libs-all' failed
make: *** [libs-all] Error 2
make: *** Waiting for unfinished jobs....
And i386 for Debian has still the same error [3]:

Hi! > What if we added "libs" as dependency for all tests and always expanded > LDFLAGS for all libraries even if tests don't link against them? > Then we wouldn't need to specify "LTPLIBS". Just a thought. That way if we ever wanted to fix the "rebuild tests after library change" it will will rebuild a whole LTP even after change in a library that is used in just a few packages...

Sigh, the out-of-tree build is always making things unnecessary difficuilt. I have no idea why the directory is not created in the build tree. > And i386 for Debian has still the same error [3]: > /usr/src/ltp/libs/libltpnuma/tst_numa.c:200: undefined /tmp/ccO9srN7.o: In function `verify_set_mempolicy': > /usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:105: undefined reference to `numa_allocate_nodemask' > /usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:110: undefined reference to `numa_bitmask_setbit' > /usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:112: undefined reference to `set_mempolicy' Not at all, this is very different problem :-). Now it fails to build in these tests that actually use the library. So original problem was fixed and this is quite possibly wrong config guards used in the tst_numa.c. I do use ifdef HAVE_NUMA_H in the library in the library and tests it should be probably replaced by HAVE_NUMA_V2. Still I would say that the original patches should be pushed and that we should deal with the rest of the problems in separate ones.

Hi, > And on my machine out-of-tree build does not managed to get past > configure step, it fails somewhere in the ffsb configure step. I often get configure:2889: error: source directory already configured; run "make distclean" there first So I build it with a bit drastic way: rm -rfv *; git reset --hard; ./build.sh -o out Kind regards, Petr

This hooks up libs/ subdirectories into the build system so that tests needs only specify which library from libs/ directory we should link againts. Which sets up the path to the library in LDFLAGS and also causes the library to be rebuild even when make is executed from the directory with testcases. Now the test only needs to set up LTPLIBS variable with a list of optional libraries to link against and LDLIBS, since as far as I know we have to maintain the order of the libraries manually.
