Question

我尝试使用valac编译器在Ubuntu 14.04中编译vala文件，并且：

$ valac -X "-I/usr/include/lua5.2" --pkg lua --pkg gtk+-3.0 main.vala
/home/gabriel/Documents/opera/cpp/tisserand/src/main.vala.c: In function ‘main’:
/home/gabriel/Documents/opera/cpp/tisserand/src/main.vala.c:156:2: warning: ‘g_type_init’  is deprecated (declared at /usr/include/glib-2.0/gobject/gtype.h:667)  [-Wdeprecated-declarations]

我已经安装了liblua 5.2，/usr/include/lua5.2已经安装了lauxlib.h，lua.h，lua.hpp，luaconf.h和lualib.h。什么遗失了？

您还需要链接liblua5.2：

valac -X "-I/usr/include/lua5.2" -X -llua5.2 --pkg lua --pkg gtk+-3.0 main.vala

如何在valac中使用liblua52？
