Probably, unless someone knows how to work around it. We traced it to the missing AS_NEEDED in /usr/lib/libc.so: /* GNU ld script Use the shared library, but some functions are only in the static library, so try that secondarily. */ OUTPUT_FORMAT(elf32-i386) GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a AS_NEEDED ( /lib/ld- linux.so.2 ) ) -- Eric Botcazou
