How about to support compiling hxcpp with MinGW


Aug 2, 2010
Project Member #1 gameh...@gmail.com
I wont be fixing this in the near future, but I'm happy to accept a patch.  I've simply got too many platforms to work with.  If you are desperate (ie, the free MS compiler wont work ?), contact me I can have more of a think about it.

Here is a patch to use gcc if run under Msys (mingw shell) or Cygwin.  The patch checks 'uname -o' if the os is windows, to see if it is a unix subsystem.  Under cygwin, because gcc/g++ may be a cygwin-specific symlink, it also tries g++-4 and g++-3.  Two new toolchains are added.

Additionally, I had to change some of the preprocessor conditions in the thread sources to check for HX_WINDOWS instead of _MSC_VER.

This patch works for me, but I have all 3 dev environments installed (msvc, msys, cygwin), so it's possible others run into something missing I did not.  Try it out.

Hi rajabiy, thank you for testing.

It seems the compile thread throws an error but does not say what it is.  Is there any useful information in your 1.log file?

Note that after applying the patch you must recompile the build tool with build-tool/Compile.hxml

Нello.
I just copied svn code to real installed lib (with replace) - F:\bin\haxe\lib\hxcpp\2,06,1
And i got error on compiling test project.

Hi,
It works ok for me here, so it is probably just something with the setup.

What version of mingw are you using?
c:/MinGW/bin/g++.exe --ver
I get 4.5.0

It looks something to do with include paths.  You could try removing the "precompile" line:
<set name="USE_PRECOMPILED_HEADERS" value="gcc"/>
from hxc[[/build-tools/gcc-toolchain.xml
And see if that does the trick.

Finally, you could try setteng the HXCPP variable explicitly to:
f:/bin/haxe/lib/hxcpp/2,06,1/
via your shell or advanced computer settings.  Also, I assume this directory exists and includes "include/hxcpp.h"

To set hxcpp to the svn version, I usually download the svn version and then use "haxelib dev hxcpp path_to_svn_version", which saves some copying.
Status: Fixed

mingw version - 4.5.0

I removed the "precompile" line and it works. 
Thanks.
