Building and using GCL 2.6.2 on OpenBSD
PLATFORMS
---------
GCL has only been tested on OpenBSD/i386 3.4. Newer versions should
work as well. Other hardware platforms are unchartered land.
TOOLS
-----
You need GNU make to compile GCL. If you have installed the ports
tree, you can get it by running the following as root:
cd /usr/ports/devel/gmake
make install
It is then installed as `gmake'.
The sed that ships with OpenBSD 3.4 has a bug (PR 3677) which is
triggered by the GCL makefiles. You can use either the sed of 3.5 or
GNU sed. Make sure the correct sed comes first in your PATH.
BUILDING
--------
There's nothing special to do for OpenBSD; GCL should build out of
the box. The OpenBSD version shares makefiles with FreeBSD, so don't
be surprised when you see "FreeBSD" in the output.
NOTES
-----
The default limits on data segment size are 64MB (soft) and 256MB
(hard). GCL will automatically raise the soft limit to the hard
limit, but you may find that it runs out of memory anyway. If so,
you can change the limits in /etc/login.conf.
For the record, the W^X feature of OpenBSD is disabled, since it
interfers with the way GCL dumps its executable.
