For a long time, we've been stuck on CMake 2.8 because later versions silently hang for us. This is doing in-source builds, which I know are considered Evil, but we can't move off them yet.
We had another problem (see my earlier posts with Subject: Dependency weirdness) that turned out to be related to a bug in CMake, Cygwin, or Windows, where the dependencies worked if the source directory had a period in the name and didn't if not, due to a case mismatch in the CMakeLists.txt. That led me to wonder whether that was causing the hang. I do not believe it does. I installed CMake 3.0.1 and did NOT customize it to support the cross-compiler we're using, then switched to it and tried that. Hang. This is the CMake command: cmake -DCMAKE_TOOLCHAIN_FILE:string="%~dp0\zosport.cmake" -G"Unix Makefiles" .\ Hmm, sez I, I wonder if it's due to the lack of cross-compiler support. I know, I'll copy the CMakeLists.txt to c:\temp and try it there. Hang. What about 2.8? I removed (well, renamed) the compiler support and tried it: C:\temp>cmake -DCMAKE_TOOLCHAIN_FILE:string="%~dp0\zosport.cmake" -G"Unix Makefiles" .\ CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CMakeDetermineSystem.cmake:92 (MESSAGE): Could not find toolchain file: %~dp0\zosport.cmake Call Stack (most recent call first): CMakeLists.txt:8 (project) CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.

Seems like the hang in 3.0.1 is wrong, but I don't have the skills to tell. And since the Toolchain file is not missing in the actual path, this isn't necessarily the same hang, but it seems worth understanding. The hang *feels* like something is getting a null input and is thus trying to read from stdin, though typing junk on the console doesn't make it happy, even with a ^Z after it. Any ideas? ...phsiii
