How to fix error: Cygwin gcc cannot be used with --compiler=mingw32
The error "Cygwin gcc cannot be used with --compiler=mingw32" occurs when there is a mismatch between the compiler specified in the build configuration and the actual compiler used by Cygwin. To fix this issue, you need to ensure that you are using the correct compiler.
Here are the steps to fix the error:
Check your Build Configuration:
Open the build configuration file (e.g.,CMakeLists.txt
orconfigure.ac
) of your project and look for the--compiler
flag. It should be set tomingw32
as you are using Cygwin with MinGW.Check Your Environment:
Make sure that Cygwin and MinGW are correctly installed on your system, and the necessary environment variables are set correctly. Cygwin and MinGW use different paths for their installations, so it's essential to ensure that you are using the correct paths.Update the Compiler Path in CMake (if applicable):
If you are using CMake to build your project, you may need to update theCMAKE_C_COMPILER
andCMAKE_CXX_COMPILER
variables in yourCMakeLists.txt
file to point to the MinGW compilers instead of the Cygwin compilers.Check the PATH Environment Variable:
Ensure that the directory containing the MinGW compiler (gcc
andg++
) comes before the directory containing the Cygwin compiler in the PATH environment variable. This will ensure that the MinGW compiler is picked up first when running commands from the Cygwin terminal.Check the SHELL Environment Variable:
If you are running Cygwin from another shell or environment (e.g., Git Bash or PowerShell), ensure that theSHELL
environment variable points to the correct Cygwin shell executable (e.g.,/bin/bash
).Restart the Cygwin Terminal:
After making any changes to the environment variables or configurations, it's a good idea to restart the Cygwin terminal to ensure that the changes take effect.
If you are using other build systems or tools, similar principles apply. Double-check the compiler settings, environment variables, and build configurations to ensure that everything is set up correctly for using Cygwin with MinGW. If the issue persists, consider seeking help on relevant forums or mailing lists specific to your development environment and tools.
