[Mono-list] Compile error with current cvs

[Lluis Sanchez]

Hi,

I've been tracking down the source of the problem, and it seems to be in
autoconf.
The script mono-build-w32.sh selects the stable version of autoconf, which
generates a configure script that fails to detect gc.h, due to a problem
already pointed out by Francisco Figueiredo some mails ago. This is the
output in config.log:

configure:6525:
gcc -mno-cygwin -E -I/home/Lluis/install/include -DGC_WIN32_THREADS -DWIN32_
THREADS conftest.c >/dev/null 2>conftest.out
In file included from configure:6521:
/home/Lluis/install/include/gc/gc.h:61:1: warning: "GC_WIN32_THREADS"
redefined
conftest.c:1:1: warning: this is the location of the previous definition
configure: failed program was:
#line 6520 "configure"
#include "confdefs.h"
#include <gc/gc.h>


This problem can be solved by commenting the #define GC_WIN32_THREADS in
gc.h. Then, it compiles.

On the other hand, the script autogen.sh does not select the stable version
of autoconf, so when it is not executed through mono-build-w32.sh, it uses
the devel version to generate the configure script. This script does not
fail to detect gc.h as far as CPPFLAGS is set to my install/include
directory. However, the libtool script generated by this configure script is
unable to link the jit, since it generates all those "undefined reference"
errors.

So to compile using autogen.h I had to include this in the script:


CPPFLAGS="$CPPFLAGS -I/home/Lluis/install/include"
LDFLAGS="$LDFLAGS -L/home/Lluis/install/lib"
export CPPFLAGS
export LDFLAGS

if [ ! -z "${AUTO_STABLE}" -o -e /usr/autotool/stable ]; then
export AUTO_STABLE=${AUTO_STABLE:-/usr/autotool/stable}
export AUTO_DEVEL=${AUTO_STABLE}
fi


Well, I've been able to compile and install... and now I get this when error
when running mono:

** ERROR **: file jit.c: line 4101 (mono_get_lmf_addr): should not be
reached

But that's another problem ...

Regards,
Lluis.
