cmake: problèmes spécifiant le compilateur

J'ai un problème avec cette CMakeLists.txt fichier:

cmake_minimum_required(VERSION 2.6)

SET(CMAKE_C_COMPILER C:\\MinGW\\bin\\gcc)
SET(CMAKE_CXX_COMPILER C:\\MinGW\\bin\\g++)

project(cmake_test)

add_executable(a.exe test.cpp)

L'appel de cmake avec: cmake -G "MinGW Makefiles"

J'obtiens:

c:\cmake_test>cmake -G "MinGW Makefiles" .

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: Internal CMake error, TryCompile configure of cmake failed
CMake Error: your C compiler: "C:\MinGW\bin\gcc" was not found.   Please set CMAKE_C_COMPILER to a valid compiler path or name.
CMake Error: your CXX compiler: "C:\MinGW\bin\g++" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
-- Configuring incomplete, errors occurred!

J'ai aussi essayé avec:

C:\MinGW\bin\g++
/C/MinGW/bin/g++

avec le même résultat. Guillemets n'ont pas été utiles, soit.

Bien sûr, le compilateur est présent dans le répertoire spécifié.

Vous remercie de tout soupçon.

  • SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc) est un peu plus facile à utiliser.
  • Nice, un mélange de Windows et Unix syntaxe 😉
  • FYI: barres obliques ont été pris en charge depuis DOS 2.0!
  • et il semble que vous avez besoin ".exe" à la fin des noms de fichiers
