[CMake] CMake 2.8.2-rc2 ready for testing!

Wed Jun 16 22:31:29 EDT 2010

Hi David,

You have raised the right concern.  My intention is not to compare various MinGW builds but to understand how to configure Cmake 2.8.2 to build with MinGW-W64, since this support is being added to CMake.  As it stands now, given lack of understanding of how to do this with CMake, I am unable to make CMake 2.8.2 RC2 do anything that CMake 2.8 stable cannot do on with respect to MinGW-W64.  They both seem to do the same thing with both automatic (neither Cmake version works) and Sezero (both Cmake versions work) builds.  I must be configuring something incorrectly.

In other words, how is CMake team testing with MinGW64?  Including where is it being downloaded from (since there is no "release" or "stable" build of it AFAIK).

PS:  I am ready to help wherever I can on this since I am interested in MinGW-W64 support.

Best regards - Alok

Hi all,

I am unable to build using MinGW-W64, but chances are there would be some configuration issues.

Here is how I am setup right now:

1.  Download latest "automatic" builds (W64 and W32) from here:  http://mingw-w64.sourceforge.net/

2.  Removed prefixes:  For example, renamed file "x86_64-w64-mingw32-g++.exe" in the bin folder to "g++.exe".  Am I not supposed to do this anymore?
3.  Added CMake 2.8.2 RC2 as well as "one" of W64 and W32 to the path.

4.  cmake . -G "MinGW Makefiles"      // This could be wrong for W64, but fails for even W32.
     This step is where I get various errors from CMake.  It works fine with normal MinGW.
5.  Then I usually call "mingw32-make" but that is not even there in MinGW-W32 and MinGW-W64!!

Also of note:  The following workaround works, even with the CMake 2.8 stable version.

1.  Use Personal/Sezero builds from http://mingw-w64.sourceforge.net/

2.  Prefixes are already removed in Sezero builds.
3.  Add only the "needed one" of W64 and W32 to the path.
4.  cmake . -G "MinGW Makefiles"   // Works for both W32 and W64
5.  "mingw32-make" is present in both W32 and W64 builds. 

I would appreciate this more, on this list, in reply to this thread, at this time ... if it were at all clear to me that you were comparing a prior CMake release to the currently proposed CMake 2.8.2-rc2.

Rather, it seems like you are comparing "latest" "automatic" builds of mingw-w64 to Personal/Sezero builds of mingw-w64.
If you use CMake 2.8.2-rc2 with the Personal/Sezero builds, do you see a difference as compared to CMake 2.8.0 or 2.8.1 with the same Personal/Sezero builds?

If this is a mingw-w64 issue, perhaps you could raise it on their mailing lists?

Thanks,David Cole

Best regards - Alok
