无法编译使用子弹物理的程序

Question

为什么我不能编译一个使用Bullet Physics的程序?

configure.ac:

PKG_CHECK_MODULES([bullet],[bullet])

src/Makefile.am:

myapp_CFLAGS = ... ${bullet_CFLAGS}
myapp_LDADD = ... ${bullet_LIBS}

试图编译它会给我以下错误:

$ LC_ALL=C make

我已经安装了Ubuntu软件包libbullet-dev，并且文件存在于文件系统中。

我自己找到了解决办法。

不是

myapp_CFLAGS = ... ${bullet_CFLAGS}

我应该用

myapp_CPPFLAGS = ... ${bullet_CFLAGS}
