Hi all,
I recently attempted to switch from autotools to cmake for building
wireshark, but for some reason cmake won't link liblua properly:
lib/libwireshark.so: undefined reference to `lua_tonumber'
lib/libwireshark.so: undefined reference to `lua_call'
lib/libwireshark.so: undefined reference to `lua_pcall'
lib/libwireshark.so: undefined reference to `luaL_loadfile'
lib/libwireshark.so: undefined reference to `luaL_register'
If I compile with VERBOSE=1, the failing gcc command is:
/usr/bin/gcc -O2 -g -Wall -W -Wextra -Wendif-labels -Wpointer-arith
-Warray-bounds -Wcast-align -Wformat-security -fexcess-precision=fast
-Wdeclaration-after-statement -Wno-pointer-sign -Wold-style-definition
-Wl,--as-needed CMakeFiles/dftest.dir/dftest.c.o
CMakeFiles/dftest.dir/ui/util.c.o -o dftest -rdynamic

The switch "-llua5.2" does exist in the above line, and is the correct
switch, so I guess it's just not late enough in the list of libraries.
Knowing nothing about cmake, I thought I'd ask here - where should I
be looking to figure out what's gone wrong? Autotools builds (and
links with liblua) correctly.
Thanks,
Evan
