Resolution| |WONTFIX--- Comment #1 from Thomas Petazzoni <[email protected]> 2012-03-08 08:24:59 UTC --- Thanks for your bug report.
The help text of the ltp-testsuite package says:
"""
The LTP testsuite uses several functions that are considered obsolete, such as sigset() and others. Therefore, the LTP testsuite does not build with Buildroot's default uClibc configuration, and options such as UCLIBC_HAS_OBSOLETE_BSD_SIGNAL are needed.
"""
So, it is well-known that ltp-testsuite doesn't build with our default uClibc configuration. You must add the uCLIBC_HAS_OBSOLETE_BSD_SIGNAL option to it. So you should do:
make clean
make uclibc-menuconfig
# add the UCLIBC_HAS_OBSOLETE_BSD_SIGNAL option make
and then it should work.
A good improvement would be to adapt ltp-testsuite so that if sigset() isn't available, it doesn't try to use it.
