Looks like things work fine on Linux. I tried again on OS X, using exactly the commands you are using, but with two modifications: * As listed on http://lua-users.org/wiki/BuildingModules for OS X: “However, unlike GCC on other platforms, you must still link with the option '-undefined dynamic_lookup' to avoid getting undefined references to liblua” * I seem to have luatex inside $SVN/trunk/build/texk/web2c/ instead of $SVN/trunk/bin, so I changed that > cat compile.sh CC=gcc SVN=/Users/deepak/code/personal L=$SVN/trunk/source/libs/lua52/lua-5.2.4/src rm -rf *.o *.la *.lo .libs/ $CC -O2 -fpic -c harfbuzz.c $CC -O -shared -fpic -undefined dynamic_lookup -o harfbuzz.so harfbuzz.o $SVN/trunk/build/texk/web2c/luatex -luaonly test.lua > ./compile.sh error loading module 'harfbuzz' from file './harfbuzz.so': dlopen(./harfbuzz.so, 6): Symbol not found: _luaL_setfuncs Referenced from: ./harfbuzz.so Expected in: flat namespace in ./harfbuzz.so However with my standard Lua installation on OS X, I get the expected result: > which lua /usr/local/bin/lua > lua test.lua Deepak
