CMake交叉编译生成无效的链接器选项 [英] CMake cross-compiling generate invalid linker options

问题描述

我正在使用CMake在具有特定工具链(nios2-linux-gnu-g ++.exe(Sourcery CodeBench Lite 2013.05-43)4.7.3)的Linux和Windows中进行编译.

I am using CMake for compiling in Linux and Windows with a specific toolchain (nios2-linux-gnu-g++.exe (Sourcery CodeBench Lite 2013.05-43) 4.7.3).

从CMake生成的选项"-Wl，-out-implib，myapp.dll.a"和"-Wl，-主要图像版本，0，-次要图像版本，0"链接器对编译器无效.

The options "-Wl,--out-implib,myapp.dll.a" and "-Wl,--major-image-version,0,--minor-image-version,0" generated from CMake to linker are invalid for compiler.

编译器错误:

• nios2-linux-gnu/bin/ld.exe:无法识别的选项'--out-implib'
• nios2-linux-gnu/bin/ld.exe:无法识别的选项'--major-image-version'
• nios2-linux-gnu/bin/ld.exe:无法识别的选项'--minor-image-version'

推荐答案

我通过在工具链文件中设置变量 set(CMAKE_SYSTEM_NAME Generic)解决了该问题.我使用的是Windows，而不是Generic，当我更改为"Generic"时，这一代工作正常.

I solved the problem by setting the variable set(CMAKE_SYSTEM_NAME Generic) in the toolchain file. I was using Windows than Generic, when I changed to "Generic" the generation works fine.
