[Mono-dev] OpenBSD 3.8 compilation

[pablosantosluac at terra.es]

Hi all,

Well, I didn't find any precompiled mono for OpenBSD, so I tried myself...

Steps I had to made

1) in support/mph.h
    #if defined (PLATFORM_WIN32) || !defined (EOVERFLOW)

    important || instead of && because EOVERFLOW is not defined in OpenBSD 
either!

2) in  libgc/include/private/gc_priv.h

instead of
#       define SIG_SUSPEND SIGRTMIN + 6*/
define

#       define SIG_SUSPEND SIGUSR1

3) define isnormal, that is not defined in OpenBSD
in mono/dis/get.c:#define isnormal(a) (finite(a) && (a) != 0.0)

4) Packages to install:
bison-1.35p1        GNU parser generator
glib2-2.6.4         general-purpose utility library
pkgconfig-0.15.0p0  tool for managing library compile/link flags

5) install both GNU sed and GNU make (you can go with 'included' make until 
mcs compilation).

6) export CFLAGS=-DGC_PTHREADS

7) 
 ./configure --with-gc=included -with-ikvm-native=no --prefix=/opt/mono-1.1.10

I got an error in ikvm, so I just removed it...


8) compile libgc with normal make... well, I don't know why, but with gmake 
it doesn't compile the include GC_pthread_create function... and then you 
get one of those undefined reference errors

Then you can get a "mini/mono" compiled, but when it tries to run mcs.exe...

you get
GC Warning: GC_get_nprocs() returned -1


and it never exits but never does anything...

Ideas?
