CMake

[mpapierski]

Hello,

Here is my attempt to "cmakify" msgpack-c library. The support is basic and there is still few things to do (like INSTALL command, removing Makefiles, automake scripts and so on) thought you are able to build msgpack library in your project using ADD_SUBDIRECTORY. This was my primary goal.

Preprocess script is fully integrated within CMake script. It calls Ruby that generates header files.

I have also removed Visual Studio projects and solutions which are completely useless now. To generate Visual Studio solution you have to run CMake with proper -G switch.

Hi, i also have my own private branch that shares the same goal.
From my branch:

• You might have to mark source language as CXX on MSVC. Msgpack-C uses C99 constructs that are not available on VS. https://github.com/okuoku/msgpack-c/blob/d3dc29756fc0961ff3d2efe051aa1a682c5aa46e/CMakeLists.txt#L95
• CMake has file(MAKE_DIRECTORY ...) command to make directory at configuration time. (edit: make_directory() was deprecated long ago. It is still usable though.)
• Is there any specific reason to remove autotools stuff from the repository? Since not every packaging system do support CMake, I personally feel it might be better to keep them as-is.

1. Good point.
2. That was stupid. I knew about this but I somehow did make_directory through cmake command.
3. I thought about the pain of supporting both build systems at once. Can you tell me what packaging systems do you mean?

I thought about the pain of supporting both build systems at once. Can you tell me what packaging systems do you mean?

For example, FreeBSD ports and pkgsrc supports CMake as build system. What we need is just saying USE_CMAKE=yes in their recipe so the system would take care remaining things (adding cmake itself in our build dependencies, invoke CMake configuration with cmake command, ...)

Unfortunately, most binary-package-minded packaging systems such as RPM has no direct support. We have to re-package if we drop autotools.

We RPM packagers really don't have need to use both building systems at the same time. We just build it and use it.

+1 for this, any reason why this shouldn't go through?

Even if autotools are not removed CMake would be a big help for windows - e.g. build with MSVC or Mingw.

Solved by #87 . Thanks!

Ok.

I hope you can release 0.59 soon.
