为什么在编译时忽略我的标题？

Question

我试图在Centos 7上编译dahdi-linux。我已经安装了gcc-9和最新的内核(我需要dahdi-echocan-oslec，标准内核太老了)，这是错误的。

请求的标头在这里

ls /opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/include/stdbool.h 
/opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/include/stdbool.h

我试过了..。

make CC=/opt/rh/devtoolset-9/root/bin/gcc LDFLAGS'-I/opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/include/'
make CC=/opt/rh/devtoolset-9/root/bin/gcc CFLAGS'-I/opt/rh/devtoolset-9/root/usr/lib/gcc/x86_64-redhat-linux/9/include/'
make CC=/opt/rh/devtoolset-9/root/bin/gcc  CFLAGS="-Wall -O2 -pipe -fPIE" LDFLAGS="-z now -pie -I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr" CPPFLAGS="-I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr"

而且还

export CFLAGS="-I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr"
export CPPLAGS="-I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr"
export LDFLAGS="-I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr"

然后

make CC...

而且还

export EXTRA_CFLAGS="-I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr"
make CC=/opt/rh/devtoolset-9/root/bin/gcc EXTRA_CFLAGS="-I/opt/rh/devtoolset-9/root/usr/include/c++/9/tr"

但失败了

找到解决办法了。在编译dahdi的新内核上，我们需要一些补丁，一个是关于最新的dahdi "14-dahdi-do-not-use-stdbool.h-in-kernel-modules.patch“，您可以在Debian dahdi软件包来源上找到它。
