[Coin-discuss] Problem with MinGW

[Ted Ralphs]

A while back, I compiled COIN under Eclipse with CYGWIN and it worked
fine using the COIN build system (i.e., Standard Make C++ Project). In
theory, the same should be true with MinGW, but the COIN build system is
not yet set up to recognize the MinGW environment (i.e., there is no
Makefile.MINGW). This is relatively easy to fix, as long as you only
want to use gcc as your compiler, since the options are essentially
identical to those that work in CYGWIN. We were in the process of fixing
this and also adding the ability to build with Microsoft's compiler with
GNU make under MinGW, when we decided that the best solution would be to
just start using the GNU autotools, which would take care of all this
stuff for us.

We are currently in the process of converting to the use of the
autotools, so you may have to wait just a little while longer for
automated MinGW build support, unless someone wants to add a temporary
fix to the current build system to detect the MinGW/gcc environment.
This should not be hard and I may be able to do it if there is a need
for it. In any case, however, I would strongly suggest not trying to use
the Managed Make C++ Project option with COIN. It will almost surely
fail, as there are lots of compiler defines and special options needed
to build COIN.

Cheers,

Ted
