RE: [Gcl-devel] Re: OpenBSD and GCL

[Mike Thomas]

Hi Magnus.

Many thanks for the info.

I'll look into those attachments later in the week when I get back to this
problem - it's kind of a background relief task for me at the moment when I
get frustrated with the Windows port.

Once I know what is happening I'll let you know so that you can get set up.

I did some nore work on this last night and the main problems were that, as
it is distributed, OpenBSD 3.4 does not have GNU sed, GNU make, no isnormal
and in ieeefp.h, no FP_NZERO.

I just copied the h/FreeBSD.* files to OpenBSD.* and made appropriate
changes. By working around the problems with isnormal and friends I got to
the point where the BSD sed stopped me.

I am now wondering whether the best strategy is to try and modify the source
of GCL so that it works oput of the box on a stock standard OpenBSD or
whether to ask potential builders to "download this, download that etc".

There seems to be no OpenBSD 3.4 version of GNU sed available for download
so it will probably have to be built from scratch - not attractive to
potential users and I suspect against the OpenBSD philosophy of sticking to
the audited, "officially blessed" packages.

Cheers

Mike Thomas

|
| I started to port GCL to OpenBSD, but have no complete success yet due
| to lack of time and skills.
|
| The attached patch against CVS head is what I have so far.  I haven't
| really sorted out the clean way of doing what I've done, so parts of
| it are OpenBSD-specific.  I'm also not sure whether all of it is
| needed.  The patch to configure.in, though, is probably cross-platform
| correct, though it should be cleaned up.
|
| With these patches, and compiling with --enable-machine=FreeBSD and
| either --enable-custreloc or --enable-dlopen, the compile proceeds
| unto creation of raw_pre_gcl.  Running raw_pre_gcl gives a "Memory
| fault", due to infinite recursion eating stack space.
|
| The problem starts in o/alloc.c, line 149, where memory allocation
| fails and an error is reported.  For some reason, reporting that error
| starts memory allocation, which fails... etc.
|
| Line 149 is:
|       IF_ALLOCATE_ERR error("Can't allocate.  Good-bye!");
|
| The IF_ALLOCATE_ERR macro is defined in h/bsd.h, and calls
| FIX_RANDOM_SBRK in the same file.  It seems to me that sbrk() on
| OpenBSD doesn't behave as this code expects it to behave.
|
| That's where I'm stuck.  I don't know how to proceed from that.

| Magnus
