OBNC - a new Oberon compiler

[miasap]

Hi everyone,

I have just released a compiler for the Oberon programming language
called OBNC. It is released under the GNU General Public License.
Please, try it out!

Hi Karl,

it's great !

I would like to try it on Window 10 (worked some years with Modula 2)

so is there a chance to create the compiler for Windows 10

with a short TODO ?

Best regards,
Friedhold

I'm glad to hear you like it. I haven't tried to build OBNC on Windows
yet (I run Debian on all my machines). If you have the Windows Subsystem
for Linux, Cygwin or MinGW on your computer you should be able to
compile OBNC from source. If you experience any problems, please let us
know.

Karl

Hi Karl,
thanks, I have not experience with MinGW (new projects) - only used it with 'ready TODO's' yet. It would save me some time if I get a short TODO (from the beginning) , I have installed MinGW TDM-GCC-64 - it works in NetBeans & C++ for me.

Thanks again,
regards
Friedhold

1. Install the garbage collector GC (http://www.hboehm.info/gc). Sorry,
but I can't help you with the exact details here. Maybe you can find a
pre-compiled version.

2. Download the latest version of OBNC from http://miasap.se/obnc
(currently 0.6.4) and store the tarball in /usr/local/src in the MinGW
installation (or use some other directory of your choice).

3. In a MinGW terminal window, go to the source directory (cd
/usr/local/src) and extract the archive with the command

tar xf obnc_0.6.4.tar.gz

4. Enter the package directory:

cd obnc_0.6.4

5. Follow the instructions in the README file (run build, test and install)

No, still got this weird Invalid cross-device link message.

Ok, changed my TMPDIR (after looking in the source). With 'export
TMPDIR=~' it works fine.

I searched for the error message and it seams to occur in some
situations when the source and destination directory are on different
partitions or hard drives. I will try to come up with a solution.

This problem should be resolved in OBNC 0.6.8. The temporary files are
now written to the output directory `.obnc'.

Hi Karl,

I like it! Under Linux Mint the installation procedure worked as expected. I especially like the clear documentation and the easy way one can get started to compile and run Oberon-07 programs.

I also tried to get it installed and running under macOS Sierra (10.12.5).
Installing the BDW garbage collector and the SDL framework is done a bit differently under macOS.
apt install libgc-dev libsdl1.2-dev
or
apt-get install libgc-dev libsdl1.2-dev
didn't work. I got messages like "Couldn't find package libgc-dev".

For libgc this worked:
brew install bdw-gc
So you will have to install the homebrew package manager first (https://brew.sh/ ).

Also installed SDL1.2 for macOS:
- downloaded SDL-1.2.15.dmg from http://www.libsdl.org/download-1.2.php
- copied the file SDL.framework to /Library/Frameworks

After this ./build worked correctly.
But ./test gave the following messages:
cd /Users/hk/Downloads/obnc-0.7.1/src
./MapsTest
./test: line 27: 6514 Segmentation fault: 11 ./MapsTest

Then ./install seems to work correctly. Everything gets intstalled as far as I can see. But when trying to compile hello.obn with
obnc hello.obn
Nothing seems to happen, no error message, no compilation.

Could you suggest something to make obnc work under macOS?

Thanks,

Hans Klaver

That's really nice to hear.

If you have the debugger GDB you can compile OBNC with debugging
information:

./build clean
CFLAGS=-g ./build

Then go to the source directory and build the unit test module for Maps:

cd src/
../bin/micb MapsTest.c

Now, run the debugger to get a backtrace:

gdb MapsTest
(gdb) run
(gdb) backtrace

What does it say?

hello.obn Nothing seems to happen, no error message, no compilation.

Probably caused by a segmentation fault in a subcommand related to the
issue above.

Had to install GDB first, which was a bit adventurous (had to make a certificate in the process). But I managed. Then proceded as you indicated.

This is the output:

(...)
Reading symbols from MapsTest...done.
(gdb) run
Starting program: /Users/hk/Downloads/obnc-0.7.1/src/MapsTest
[New Thread 0x1403 of process 1945]

Hoping this gives you some clue.

I have now released OBNC 0.8.0 and Obnc-libstd 0.2.1 which should work
in macOS:
