Question

我正在使用CMake在Linux和Windows中使用特定的工具链进行编译（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， - major-image-version，0， - minor-image-version，0”链接器对编译器无效。

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'

CMakeCache.txt：

有关如何解决此问题的任何想法？

Answer 1

我通过在工具链文件中设置变量集（CMAKE_SYSTEM_NAME Generic）解决了这个问题。我使用的是Windows而不是Generic，当我改为“Generic”时，这一代的工作正常。

Answer 2

这些设置来自CMake本身：

http://cmake.org/gitweb?p=cmake.git;a=blob;f=Modules/Platform/Windows-GNU.cmake;h=990acea64c3b0666edf28eb3604e626a219af04d;hb=HEAD#l113

您可以尝试将CMAKE_${lang}_CREATE_*复制到工具链文件中，并删除导致问题的位。我不知道这些标志是做什么的，所以删除它们可能会导致其他问题，你必须解决。
