Summary: Review Request: tolua++ - A tool to integrate C/C++ code with Lua https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=193884 ------- Additional Comments From packages@xxxxxxxxxxxxxxxxxx 2006-06-03 17:37 EST ------- Just noticed Hans, those link flags DO break tolua++. I'm currently investigating a fix, but it appears to be because the exe has the same 'soname' as the library. With those link flags, do an ldd on the tolua++ binary, you get: linux-gate.so.1 => (0x004df000) liblua-5.1.so => /usr/lib/liblua-5.1.so (0x0063c000) libdl.so.2 => /lib/libdl.so.2 (0x00111000) libm.so.6 => /lib/libm.so.6 (0x00115000) libc.so.6 => /lib/libc.so.6 (0x004fe000) /lib/ld-linux.so.2 (0x004e0000) Strange I thought, it isn't dynamically linked to libtolua++-5.1.so. Checking the build, it certainly does link it to this library so why isn't it showing. I checked the exe and if you try and do anything useful with it you get: tolua++: symbol lookup error: tolua++: undefined symbol: tolua_open which sort of confirms that ld isn't dynamically linking it. Now if you remove those LINK flags rebuild and do an ldd, you get: linux-gate.so.1 => (0x004df000) libtolua++-5.1.so => /usr/lib/libtolua++-5.1.so (0x00200000) liblua-5.1.so => /usr/lib/liblua-5.1.so (0x0067a000) libdl.so.2 => /lib/libdl.so.2 (0x00650000) libm.so.6 => /lib/libm.so.6 (0x00629000) libc.so.6 => /lib/libc.so.6 (0x004fe000) /lib/ld-linux.so.2 (0x004e0000) Notice, libtolua++-5.1.so shows this time? I think because ld is using the 'soname', it already discovers this 'soname' in the exe itself, so it assumes the appropriate library has been found and doesn't look any further. Without the LINK flags, neither the exe nor the library has an 'soname' so ld falls back to the library name, ie libtolua++-5.1.so and finds it. Somehow I need to get scons to use the soname for the library only.
