[Mono-devel-list] Some thoughts on the windows build

[Johannes Roith]

Hello!

Here is a small collection of info/problems with the current windows
build:

Build with:

./configure --prefix=/usr/mono-0.28 --with-gc=boehm

(prefix should be a clean directory)

- Mono builds fine without GC

- The problem is the gc.

- at first the configure script claims it can't find gc.h, etc.
This can be fixed by exporting:

export CPPFLAGS="$CPPFLAGS -I/usr/local/include"
export LDFLAGS="$LDFLAGS -I/usr/local/lib"
export CC="gcc -mno-cygwin"

Eventually adapt the path.

- It will still miss GC-malloc.

This can be solved by copying gc.dll to your lib dir /lib or /usr/lib
Gc.dll is contained in the package
http://www.go-mono.org/archive/libgc-dev.zip

- Now the configure script should pass.

The build might then stop somewhere because of different things:




Case 1:

This happens, when the libgc from the cvs module libgc is installed (I
believe):

This happens, when you use the .h files from the libgc-dev.zip file.

There were some other cases, but I can't reproduce them again.

- if you manage to get pass that point and build mono to the new prefix

The wizard:

* delete the *.a and *.la the lib directory of the install directory
* copy monowiz.win32.nsi from cvs to /mono
* also copy the mono-setup-light.bmp file to /mono

* make win32setup
* make sure you have nsis4cygwin installed
(http://www.jroith.de/nsis4cygwin.zip)

I can - maybe - come to #mono in ~ 7 hours for a few minutes before
school starts, but I can't promise it.

In earlier releases for some reason the GC was not much of a problem. It
just depends on your current cygwin setup. I'm sorry, I don't know more
right know.

Good luck with everthing!
