Hi,
Here is how you can compile in 32bit mode.

Hi,
I compiled a 32bit OpenModelica on Ubuntu 64 bit in
my virtual machine. It is a pain, but it can be done.
All testsuite works for me now.
See the attached files and prepare
for some heavy compilation :)
I assumed:
mico2.3.13.tar.gz unpacked into:
/home/openmodelica/dev/mico
antlr2.7.7.tar.gz unpacked into:
/home/openmodelica/dev/antlr
MetaModelica/RML Compiler subversion into:
/home/openmodelica/dev/mmc
OpenModelica Compiler subversion into:
/home/openmodelica/dev/OpenModelica
So you might need to do some
small changes to the commands.
Some changes are needed to the current
code of both RML and OpenModelica, but
they are quite minor. See the attached
patches.
Cheers,

Hi,
I think you might need to change also the ld to
ld -b elf32-i386
This will generate 32bit output files, otherwise
they will be made 64bit.
I Googled a bit and found something else which might work:
Try this:
$ cd OpenModelica
$ make clean
$ CC='gcc -m32' CXX='g++ -m32' linux32 make
This might work better, but I don't know for sure.
Of course, I don't know if you realize this, but
also MetaModelica compiler, antlr and mico need
to be compiled in 32 bit, otherwise the linking
will not work.
I just made a virtual machine with 64bit Ubuntu
and I will try myself to see if I can fix this
somehow.
