I downloaded ICU4Lua from official site. We have *c. and *.h files. I linked them in *.o files: gcc -c *.c. Now I have many *.o files, but I don't linked in *.so. I entered: gcc -O2 -Wall -I/usr/local/include -lpthread -ldl -lm -L/usr/local/lib -licui18n -licuuc -licudata -lpthread -ldl -lm icu.o -o icu.so, but I have many errors. gcc -O2 -Wall -I/usr/local/include -lpthread -ldl -lm -L/usr/local/lib -licui18n -licuuc -licudata -lpthread -ldl -lm icu.o -o icu.so /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../lib64/crt1.o: In function `_start': /usr/src/packages/BUILD/glibc-2.11.2/csu/../sysdeps/x86_64/elf/start.S:109: undefined reference to `main' icu.o: In function `icu_convert': icu.c:(.text+0x1e): undefined reference to `luaL_checklstring' icu.c:(.text+0x40): undefined reference to `luaL_optlstring' icu.c:(.text+0x62): undefined reference to `luaL_optlstring' icu.c:(.text+0xc0): undefined reference to `lua_pushnil' icu.c:(.text+0xdc): undefined reference to `lua_pushstring' icu.c:(.text+0x150): undefined reference to `lua_pushnil' icu.c:(.text+0x16c): undefined reference to `lua_pushstring' icu.c:(.text+0x18c): undefined reference to `lua_pushlstring' icu.o: In function `icu_defaultencoding': icu.c:(.text+0x1bc): undefined reference to `lua_gettop' icu.c:(.text+0x1d6): undefined reference to `luaL_checklstring' icu.c:(.text+0x1f5): undefined reference to `lua_pushstring' icu.o: In function `icu_defaultlocale': icu.c:(.text+0x214): undefined reference to `lua_gettop' icu.c:(.text+0x235): undefined reference to `luaL_checklstring' icu.c:(.text+0x25b): undefined reference to `lua_pushstring' icu.o: In function `luaopen_icu': icu.c:(.text+0x284): undefined reference to `luaL_register' icu.c:(.text+0x295): undefined reference to `lua_pushstring' icu.c:(.text+0x2ab): undefined reference to `lua_setfield' collect2: ld returned 1 exit status Can you help me? -- View this message in context: http://old.nabble.com/ICU4lua-tp31917243p31917243.html Sent from the gcc - Help mailing list archive at Nabble.com.
