Bug in CMake with MinGW-w64 GCC 8.1

[thecheeselover]

Using the MinGW-w64 compiler for GCC 8.1.0 (seh, posix), I tried to setup the Code::Blocks project from the source files of SFML 2.5.0.

• I downloaded the code source for SFML 2.5.0 on my Windows 10 machine
• I downloaded CMake GUI and set up the correct source path and output for generating the Code::Blocks  project (MinGW makefiles)
• I checked the specify native compilers option
• I then selected x86_64-w64-mingw32-gcc.exe for the C compiler and x86_64-w64-mingw32-g++.exe for the C++ compiler
• An error would then popup after clicking ok, saying : "Error in configuration process, project files may be invalid"
• In the log file, the error only says that gcc returned 1.

I tried the same thing but with the TDM GCC 5.1.0-3 64 bit compiler and got no errors.

Did I do something wrong or CMake or SFML CMake files have errors?

Just picking the compilers doesn't work. You need to fully switch the toolchain, by having the compiler's bin directory in PATH.

Since I work with many different variants of MinGW, I tend to not have any of them in PATH and only temporarily add one when I need it by calling set PATH=<path to compiler>\bin;%PATH%

MinGW-w64 GCC 8.1.0 (POSIX, SEH) from MinGW Builds works fine for me.

I confirm what you said. It works if I put one of my compilers bin directory in PATH. The order matters if there are many. It also works with the default (autodetected) compiler.

Thank you very much.
