Question

这是一个简单的问题，我需要在mingw32上创建一个CMake构建器。我想在CMakeLists.txt中定义编译器（虽然我想在以后调用cmake时指定）。 txt文件如下所示：

cmake_minimum_required(VERSION 3.4)

SET(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_GENERATOR "MinGW Makefiles")
message("generator is set to ${CMAKE_GENERATOR}")

#set (CMAKE_Fortran_COMPILER "C:/Program Files/PGI/win64/15.10/bin")
set (CMAKE_Fortran_COMPILER "C:/Program Files (x86)/Silverfrost/FTN95")

然后它返回：

generator is set to MinGW Makefiles
-- The Fortran compiler identification is unknown
-- Check for working Fortran compiler: C:/Program Files     (x86)/Silverfrost/FTN95
-- Check for working Fortran compiler: C:/Program Files (x86)/Silverfrost/FTN95  -- broken
CMake Error at C:/Program Files (x86)/CMake/share/cmake-   3.4/Modules/CMakeTestFortranCompiler.cmake:54 (message):
The Fortran compiler "C:/Program Files (x86)/Silverfrost/FTN95" is not able
to compile a simple test program.

我做错了什么？我知道它没有正确找到编译器。谢谢你的帮助。

编辑。正如我所建议的那样，我发布了CMakeError.log

我可以在这里追踪更多信息吗？谢谢。

帮助他人：4年后，我遇到了同样的问题。我通过确保像这样CMakeList.txt指向set(CMAKE_Fortran_COMPILER "C:/MinGW/bin/gfortran.exe")中FORTRAN可执行文件的确切位置来解决了该问题。这为我解决了。让我知道它是否有效。

由于 Visual Studio 生成器不支持 MinGW gfortran。它们是完全独立的生态系统。删除您的构建目录并创建一个新目录。

所以定义生成器对我有用的是在命令行中使用一个标志来定义它

cmake -G "MinGW Makefiles"

我也尝试将 CMAKE_GENERATOR 设置为 CMakefile.txt 中的变量

set(CMAKE_GENERATOR "MinGW Makefiles")

但由于某种原因，它不起作用，我必须在命令行中传递生成器
