(0014269) Bill Hoffman (manager) 2008-12-02 12:33	I am still unable to reproduce this?

(0016149) Woojin Oh (reporter) 2009-04-22 22:00	If you change any compiler environment variables after PROJECT() line, you will get those messages. PROJECT() : check compiler environment

This is CMakeLists.txt file what I tested. and It doesn't work. # CMake script for version 2.6 cmake_minimum_required(VERSION 2.6) project("FOOBAR" C) But, after adding wrong line like - did not given PROPERTY - It works!! set_property(GLOBAL CMAKE_C_COMPILER /usr/bin/gcc) bash-2.05$ ~/cmake-2.6.1-SunOS-sparc/bin/cmake . -- Check for working C compiler: gcc -- Check for working C compiler: gcc -- works -- Check size of void* -- Check size of void* - done CMake Error at CMakeLists.txt:5 (set_property): set_property not given a PROPERTY <name> argument. -- Configuring done You have changed variables that require your cache to be deleted. Configure will be re-run and you may have to reset some variables. The following variables have changed: CMAKE_C_COMPILER= gcc -- Generating done -- Build files have been written to: /data/lab/test and but... I cannot make a program very confused.. ;-( ps. It works for 2.4.X

(0016350) Kihyun Kim (reporter) 2009-05-08 03:50 edited on: 2009-05-08 03:50	I tried more. open CMakeFiles/CMakeCCompiler.cmake and CMakeFiles/CMakeCXXCompiler.cmake file and found SET(CMAKE_C_COMPILER_ENV_VAR "CC") SET(CMAKE_CXX_COMPILER_ENV_VAR "CXX") So I found that it works good when shell env variable CC and CXX are set.

(0019754) Joel Croteau (reporter) 2010-03-07 23:42	Any progress on this bug? It still exists as of cmake 2.8.0. It happened to me while trying to compile Ogre on Mac OS 10.6, using unix makefiles, with cmake-gui. I tried specifying the compilers (CMAKE_C_COMPILER=/opt/local/bin/gcc-mp-4.5 and CMAKE_CXX_COMPILERS=/opt/local/bin/g++-mp-4.5) within cmake, and also setting the CC and CXX environment variables and telling cmake to use the defaults, and the exact same thing happened. Actually, the exact same thing seems to happen if I don't specify anything, in which case it uses the default of /opt/local/bin/g{cc,++}, it doesn't seem to want to create unix makefiles at all.

(0019755) Bill Hoffman (manager) 2010-03-08 09:38	jcroteau, that sounds like something different... If you set CC and CXX and run CMake on a clean build tree, does it work? Changing the compiler after CMake has run just does not work very well. How did you set the compiler with cmake-gui? There is a dialog that should allow you to set them, when you run cmake-gui on an empty build tree, that works right?

(0019756) Joel Croteau (reporter) 2010-03-08 11:00	Happens with clean source tree. Happens with default compilers without CC and CXX set, so not sure what is causing this now, but it is the same phenomenon described above. Compiling Ogre SVN, latest version, unmodified, into separate, empty build directory. Xcode build works alright, only when making Unix Makefiles does this happen.

(0019757) Bill Hoffman (manager) 2010-03-08 11:07	Exactly what happens, I don't think you are seeing the same thing, unless Ogre SVN is trying to change the compiler from the CMakeLists.txt files. Can you do this: 1. checkout a clean SVN copy of Ogre to OgreSource 2. mkdir build 3. cd build 4. cmake -G"Unix Makefiles" ../OgreSource >& out Then post the out file here (Truncated if it looks forever.).

(0019758) Bill Hoffman (manager) 2010-03-08 11:12	I just tried on a mac with the Tests/Simple inside CMake. 1. cd CMake/Tests/Simple 2. mkdir build 3. ccmake .. 4. push c 5. push t 6. change the c++ to g++ CMAKE_CXX_COMPILER 7. push c 8. push g It worked for me. Does it work for you?

Not sure if this is a CMake issue, or something with the Ogre CMakeLists. I didn't see anything to change the compiler there, but I will look at it more closely. Tried your test with Simple, and pressing c the second time produced the error: You have changed variables that require your cache to be deleted. Configure will be re-run and you may have to reset some variables. The following variables have changed: CMAKE_CXX_COMPILER= /opt/local/bin/g++ Pressing g after this still successfully created a makefile.

(0019764) Joel Croteau (reporter) 2010-03-08 16:32	It appears this is partly a CMake problem, partly an Ogre problem. Relevant discussion is here http://www.ogre3d.org/forums/viewtopic.php?f=2&t=53897&start=0. [^] I don't know why the inclusion of those couple lines, even when not executed should cause this issue though.

(0019765) Bill Hoffman (manager) 2010-03-08 16:57	It is an Ogre problem, you can not set the compiler from within a CMakelists.txt file. It will cause trouble almost every time...

(0019766) Joel Croteau (reporter) 2010-03-08 17:03	Ok, thanks for the help. I've submitted a patch to them that should fix it.

(0019768) Bill Hoffman (manager) 2010-03-08 17:29	I will leave the bug open, as cmake should not go into a loop like that ever... But, the Ogre folks might want to rethink how they were forcing compilers in CMake.

(0032185) CrumblingStatue (reporter) 2013-01-31 13:10 edited on: 2013-02-01 07:44	I have this same issue on Arch Linux x86_64, CMake 2.8.10.2 The working directory consists of a single source file and a single CMakeLists.txt. See workdir.tar Steps to reproduce: mkdir build cd build cmake -DCMAKE_CXX_COMPILER=g++ .. cmake -DCMAKE_CXX_COMPILER=g++ .. # Infinite loop on second invocation This is a problem if you want to use the command you used on your previous CMake invocation (and change some options), but forget to remove the -DCMAKE_CXX_COMPILER definition. (In my case, Qt Creator's "run cmake" dialog presents the previous options used) For example: cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release .. cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Debug .. # Change to Debug build infinite loop From my understanding, CMake could just ignore CMAKE_CXX_COMPILER flag if the value stays the same. (And even if it doesn't stay the same, it should print an error message like "Can't use different compilers in the same build directory, Create a new build directory!", instead of going into an infinite loop)

(0032639) Brad King (manager) 2013-03-15 09:03	Re 0008193:0032185: The infinite loop you report is issue 0013756 and is fixed in 2.8.11.
