我正在尝试使用waf-1.8.8构建一个与共享库(动态库)链接的简单c++11
程序。
特殊之处在于,我没有尝试构建此lib,因为我已经有了dev版本,这意味着声明(.hpp header )和定义(在Windows下.so
下的linux
文件,在Windows下.dll
+ .lib
的文件)。
我只是想这样链接:
$ g++ src/main.cpp -o mySFMLprogram.bin -std=c++11 -IthirdParty/SFML-2.2/include -LthirdParty/SFML-2.2/lib -lsfml-graphics -lsfml-system -lsfml-window
从我的项目的基本目录中,这很好。
不起作用的是使用wscript / waf系统进行此操作...我找不到如何使它与
-LthirdParty/SFML-2.2/lib
等效的方法(为链接器提供了新的搜索目录,man gcc
表示Add directory dir to the list of directories to be searched for -l.
)。这是我的项目的简化树:

编辑:@mkaes首先解释后更新我的文件

window.close();
}
// clear the window with black color
window.clear(sf::Color::Black);

怎么了?

此示例已解决,可以在Github上找到:https://github.com/Tyrben/SFMLProjectUsingWaf
谢谢@mkaes
最佳答案
解决此问题的一种方法是在配置阶段添加您的库。例如
cfg.env.LIB_SFML = ['sfml-graphics', 'sfml-system', 'sfml-window']
cfg.env.LIBPATH_SFML = [os.path.join(os.getcwd(), 'thirdParty/SFML-2.2/lib')]
cfg.env.INCLUDES_SFML = [os.path.join(os.getcwd(), 'thirdParty/SFML-2.2/include']
然后在您的构建中只需添加
SFML
作为use
指令即可。更新:
将您的构建更改为此:
def build(bld):
bld.program(
features='cxx cxxprogram', #is it an option ?
source='main.cpp',
target='app',
use = ['SFML']
)
