Summary | 0010738: CMake should warn when a different version of CMake is run on an existing build tree. | ||||||||
Description | Hi, I just encountered that when configuring a CMake project with Cmake 2.6 and then calling CMake 2.8 on that, that "CMAKE_SIZEOF_VOID_P" will not be defined. I don't know what else is affected by updating the version without deleting every trace of CMake configured files, but "CMAKE_SIZEOF_VOID_P" is definitely one of them. A minimal CMakeLists.txt example is attached. I called: mkdir test_build cd test_build "c:\Program Files (x86)\CMake 2.6_\bin\cmake.exe" -G "Visual Studio 9 2008" ..\test "c:\Program Files (x86)\CMake 2.8\bin\cmake.exe" . The last call will give: C:\dev\test_build>cmake . CMake Error at CMakeLists.txt:9 (message): 'CMAKE_SIZEOF_VOID_P' is undefined. Thus you should delete CMakeFiles (the directory) and the CMakeCache.txt and rerun CMake again! This is some weird CMake bug that seems to appear when updating the CMake version. -- Configuring incomplete, errors occurred! | ||||||||

ohh I forgot: C:\dev\test_build>"c:\Program Files (x86)\CMake 2.6_\bin\cmake.exe" --version cmake version 2.6-patch 2 C:\dev\test_build>"c:\Program Files (x86)\CMake 2.8\bin\cmake.exe" --version cmake version 2.8.1 |

You can not do that. With a new version of CMake, you must start with a clean build tree, this just is not supported. |

So can you at least issue a warning? Some users might not even know that their CMake was updated when the admin is in charge of the machine. This might lead to very weird behaviour... |

I changed the subject. |

Sending issues I'm not actively working on to the backlog to await someone with time for them. If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it: http://www.cmake.org/mailman/listinfo/cmake [^] It's easy to re-activate a bug here if you can find a CMake developer or contributor who has the bandwidth to take it on. |

This issue has been addressed in CMake 2.8.10 by this change: http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=7195aca5 [^] Now each version of CMake computes its own platform information. |
