我试图在Mac OSX Sierra上编译基于Allegro的游戏,但出现以下错误:
Undefined symbols for architecture x86_64:
"_al_init_ttf_addon", referenced from:
__al_mangled_main in main.cpp.o
我从源代码编译了Allegro 5.2.3,这些是我包含在游戏CMakeLists.txt文件中的库。
SET(LIBRARIES
liballegro.dylib
liballegro_acodec.dylib
liballegro_audio.dylib
liballegro_color.dylib
liballegro_dialog.dylib
liballegro_font.dylib
liballegro_image.dylib
liballegro_memfile.dylib
liballegro_main.dylib
liballegro_primitives.dylib)
include_directories(/usr/local/include)
link_directories(/usr/local/lib)
add_executable(My_Game ${SOURCE_FILES})
target_link_libraries(My_Game ${LIBRARIES})
在Allegro 5.2.3 CMakeLists.txt中,设置了以下宏:
option(WANT_TTF "Enable TTF addon" on)
option(WANT_COLOR "Enable color addon" on)
option(WANT_MEMFILE "Enable memfile addon" on)
option(WANT_PHYSFS "Enable PhysicsFS addon" on)
option(WANT_PRIMITIVES "Enable primitives addon" on)
option(WANT_NATIVE_DIALOG "Enable native dialog addon" on)
option(WANT_VIDEO "Enable video player addon" on)
option(WANT_MONOLITH "Include all addons in the main library" off)
构建和安装后,在/ usr / local / include中没有看到allegro_ttf.h,在该目录中安装了所有其他allegro头文件。我也没有在/ usr / local / lib下看到allegro_ttf.dylib。在用于快板构建的CMakeFiles / Makefile2中,我在Makefiles2中看到以下内容:
# Convenience name for "all" pass in the directory.
addons/all: addons/primitives/all
addons/all: addons/image/all
addons/all: addons/font/all
addons/all: addons/audio/all
addons/all: addons/acodec/all
addons/all: addons/color/all
addons/all: addons/memfile/all
addons/all: addons/native_dialog/all
addons/all: addons/video/all
addons/all: addons/main/all
.PHONY:插件/全部
但我看不到addons / ttf / all。任何帮助,将不胜感激。
最佳答案
问题是我没有安装freetype
brew install freetype
现在正在工作!
