Question

我正在尝试使用gcc-linaro-arm-linux编译一个用c编写的小程序，其中包含用于arm处理器的附加库zlib和libpng。

在某些.c文件中：

#include <bzlib.h>

如果我用普通的gcc编译，一切都运行正常，但是使用gcc-linaro-arm-linux编译器找不到库：

cmake的：

$cmake -D CMAKE_C_COMPILER="${HOME}/opt/gcc-linaro-arm-linux-gnueabihf-4.8-2014.03_linux/bin/arm-linux-gnueabihf-gcc" -D CMAKE_CXX_COMPILER="${HOME}/opt/gcc-linaro-arm-linux-gnueabihf-4.8-2014.03_linux/bin/arm-linux-gnueabihf-g++" CMakeLists.txt

您需要告诉CMake在哪里找到您的目标sysroot。查看CMAKE_FIND_ROOT_PATH。

Cmake将库添加到自定义gcc编译器
