[M3devel] _lowbits / _highbits (Pixmap bug-- 4.1 vs. buggy 5.x)

Fri May 30 08:31:19 CEST 2008

Also if you can send me a test case I can build and run for the current pixmap problem, please do.

I have the 4.1 CD. I bought it from Critical Mass the normal legitimate way. I hacked my cm3.exe the other day to skip the license check since I can't find my key, it's very easy to do.
My observations agree with yours -- no source on the CD to the compiler, contrib includes the DEC 3.6 code.

What are the CM3IDE problems?

What is the pixmap behavior with build_standalone()?
I'm inclined to think this is not a Modula-3 problem but hard to debug remotely like this..

Olaf / Jay:

My Reactor v4.1 CD has a source directory, but this folder does not contain the sources for the compiler or Reactor, just the libraries et al.

Here is a list of the archives in that folder:

BINUTILS.TGZ
m3-comm.TGZ
m3-db.TGZ
M3-DEMO.TGZ
M3-GAMES.TGZ
M3-LCTRN.TGZ
m3-libs.TGZ
M3-MAIL.TGZ
M3-OBLIQ.TGZ
M3-PKGTL.TGZ
M3-TOOLS.TGZ
m3-ui.TGZ
m3-www.TGZ
M3CC.TGZ
M3GDB.TGZ

There is also a CONTRIB folder with the following:

CVSUP
IDLM3
M2TOM3
M3DDD
M3PC
M3TOMIF
SRC-M3

If Farshad is ok with it, I can send you these files, but I would need his approval because we licensed this product from Critical Mass.

On a side note, I just built a new laptop computer from a fresh install of XP Pro.  I got the latest cm3 from the repository and rebuilt everything.  On this platform, my pixmaps show up with a "yellow" color everywhere "white" would normally show.  This is strange behavior.  I checked the .lst file and it is showing as a GUI program and the "hand.obj" is included.  Any ideas?

Since Jay has made good progress on fixing some of my major gripes, I am trying to use the new (current) cm3 for my project that is due for delivery at the end of July.  The new garbage collector seems to work much better on Windows than the one from 4.1.  Since we don't have an official stable release right now, I am going to have to draw a line in the sand at some point soon and take a snapshot of the cm3 source tree as the "official" development environment for future support of my project deliverables.

This latest problem with pixmaps on one platform and with CM3IDE on all XP platforms I've tested so far is disturbing.  As soon as I can get a handle on these problems, I think I am going to freeze my development environment for this project unless someone comes up with a major fix/change.

Regards,

Randy

I don't think that a complete 4.1 code set was ever imported into
the CVS CM3 repository; at least I don't remember we got the complete
4.1 code from Farshad Nayeri. What we got was 5.1 and it wasn't even
compilable by any existing M3 compiler. The gcc backend was so old
that it wasn't usable on any system we had. I think we extensively used
PM3 for booting and even incorporated some of PM3's code where
necessary.

I remember that I had several evaluation CDs from CM3 some years before
the open source release, so it may be that contents from one of these
CDs were imported as 4.1. I'm afraid it is not really traceable now.
We never got any versioned code from Critical Mass (I don't know what
they used for version control), only the bare source code.
