我有一个C项目，它支持许多平台 . 它的生成器有Borland Makefiles，NMake Makefiles，MSVC 6,7,8,9,11，Eclipse CDT4 - Unix Makefiles等 . 我在Windows 7上用cmake生成了MSVC 9解决方案 . 没关系 .
现在，我想在上述C项目的TI Sitara SDK上生成ARM Cortex A8项目 . TI Sitara SDK安装在Ubuntu 14.04 OS主机上 . 有一个交叉编译工具链：Ubuntu PC上的Linaro .
从最初的C项目文档看，下面的选择看起来适合Sitara SDK，因为它使用Eclipse（但它的帮助窗口上有8.1.1，高于CDT4）
Eclipse CDT4 ‐ Unix Makefiles
= Generates Eclipse CDT 4.0 project files.
我已经设置了编译器路径：
export CMAKE_C_COMPILER=/home/u64rj/ti-processor-sdk-linux-am335x-evm-01.00.00.03/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-gnueabihf-gcc
export CMAKE_ECLIPSE_VERSION=4.2
当我运行cmake时，仍然存在这样的错误：
u64rj@u64rj-MS-7696:~/u64rj-Fixed/sdk-2-src$ cmake -G "Eclipse CDT4 - Unix Makefiles" -DBUILD=LINUX-ARMv7a -DCFG=Debug -DMATH=I32

ARMv7a是TI Sitara AM3358芯片构建的架构 .
我不知道它为什么在C项目路径上搜索交叉编译器：CMake错误：你的C编译器：“/ home / u64rj-Fixed / sdk-2-src / arm-linux-gnueabihf-gcc”找不到 . 请将CMAKE_C_COMPILER设置为有效的编译器路径或名称 . CMake错误：内部CMake错误，TryCompile配置cmake失败 - 检查工作C编译器：/ home / u64rj-Fixed / sdk-2-src / arm-linux-gnueabihf-gcc - broken
即使工具链的交叉编译器是由导出CMAKE_C_COMPILER = / home / u64rj / ti-processor-sdk-linux-am335x-evm-01.00.00.03 / linux-devkit / sysroots / i686-arago-linux / usr / bin中/臂-Linux的gnueabihf-GCC
