转载：How to add a path to LDFLAGS

有些软件的源码包中代码管理脚本写得不完善，导致某些必须的共享库不被写入链接目标中，进而导致最终链接失败。例如Performous本身需要bzip2这个库，却没有在 configure 脚本里写上依赖关系 。解决办法就是在编译之前在LDFLAGS环境变量中手动加入需要链接的目标共享库。

亮点 ：

The question is not really descriptive enough for anyone to answer well, but....

On a Unix-based system you would likely do something like this:

$ export LDFLAGS="-R/the/path/to/the/gmp/lib -L/the/path/to/the/gmp/lib"

$ ./configure

$ make

$ make install

Windows environments with GNU make tools, will need minor tweaks.
