Created attachment 438574 [details] build.log Hi, on a Gentoo:Prefix instance I can compile with gcc-4.9.3 but not with 5.3.0: In file included from ../../sandbox-2.6/libsandbox/trace/linux/arch.c:15:0, from ../../sandbox-2.6/libsandbox/trace/os.c:6, from ../../sandbox-2.6/libsandbox/trace.c:25: ../../sandbox-2.6/libsandbox/trace/linux/x86_64.c:13:33: error: expected expression before ',' token #define S(s) { SB_SYS_x86_64_##s, SB_NR_##s, #s }, ^ ./trace_syscalls_x86_64.h:2:1: note: in expansion of macro 'S' S(CHMOD) ^ ../../sandbox-2.6/libsandbox/trace/linux/x86_64.c:13:33: error: expected expression before ',' token #define S(s) { SB_SYS_x86_64_##s, SB_NR_##s, #s }, ^ ./trace_syscalls_x86_64.h:4:1: note: in expansion of macro 'S' S(FCHMODAT) ^ ... In the attached build.log you will see LD_PRELOAD errors, which are related to the messages output during "successful" build of sandbox using gcc-4.9.3: GEN sb_nr.h CC libsandbox_la-wrappers.lo CC libsandbox_la-libsandbox.lo CC libsandbox_la-trace.lo CCLD libsandbox.la *** Warning: Linking the shared library libsandbox.la against the *** static library ../libsbutil/.libs/libsbutil.a is not portable!

Maybe installing sandbox when running Gentoo:Prefix as a non-privileged user makes no sense in the first instance?
