I just noticed that config.log shows that -static is passed to gcc.
Can you run "dpkg -L libnuma-dev" to check you have static library
to link against?
Can you link against -lnuma outside of LTP build?
For example:
cat > numatest.c <<EOF
#include <stdio.h>
#include <numa.h>
int main(void)
{
printf("%d\n", numa_max_possible_node());
return 0;
}
EOF
gcc numatest.c -lnuma
