[LTP] with-numa/without-numa option not working ?

[LTP] with-numa/without-numa option not working ?

[Rafael David Tinoco]

Hello,

Daniel has discovered that --with-numa and --without-numa practically
have the same effect, disabling NUMA support. This can be seen when
executing test "migrate_pages03", for example.

In both situations it will display:

tst_test.c:771: CONF: require libnuma >= 2 and it's development packages

config.log shows:

when --with-numa AND when --without-numa are set (or --with-numa=yes or
--with-numa=no):

NUMA_LIBS=''



#define NUMA_ERROR_MSG "NUMA support was disabled during build"



when nothing is specificied:

NUMA_LIBS='-lnuma'



#define HAVE_NUMA_H 1


#define HAVE_NUMAIF_H 1
#define HAVE_NUMA_V2 1
#define NUMA_ERROR_MSG "test requires libnuma >= 2..."

I believe something is wrong with configure.ac for NUMA (maybe some
other options ?). I'm not an autoconf expert, could someone take a look ?

Thank you

Thanks for your report. I'm the author of numa configure option, I'm aware of
it (39a85a1f1 and 4ace68a6b).
It was never meant that --with-numa would be working.  There was only
--without-numa as workaround for systems without numa libraries and devel files.
Before it was a dependency for LTP compilation.
But I know it's confusing, as it's expected both --with-PACKAGE
and--without-PACKAGE are implemented, so I'll fix it => with --with-numa
(which will be the default) it will fail to compile.

Kind regards,
Petr
