Does anyone have GDC working on an AMD64 linux system?

I've tried both compiling with GCC manually, and the 0.19 i386 binary on the
website, but neither work properly.  When I use the i386 binary, compiling
a simple test program gives me:
/tmp/ccDMD2fb.s: Assembler messages:
/tmp/ccDMD2fb.s:10: Error: suffix or operands invalid for `push'
/tmp/ccDMD2fb.s:86: Error: suffix or operands invalid for `push'
/tmp/ccDMD2fb.s:93: Error: suffix or operands invalid for `pop'

As I recall, a similar error message occurs with my compiled version.

$ gcc -v

Any suggestions?

Thanks

I don't remember seeing those error messages.

Did you try to add "-m32" to your command line?

- From my adapted gdmd file:
123:my $gcc_version = `$gdc  -m32 -dumpversion`;
128:my $target_machine = `$gdc -m32 -dumpmachine`;
291:    my @cmd = ($gdc, '-m32', '--version', @out);
332:    my @cmd = ($gdc, '-m32', '-I/opt/gdc/gdc-0.19/include/d/3.4.6/i386-unknown-linux/', @out, '-c', @all_sources_hack, $srcf, '-o', $outf );
342:    my @cmd = ($gdc, '-m32', '-L/usr/lib32', @out, @dobjects, @objects, @link_out);

I had forgotten -m32, but didn't help...

Thanks for the gdmd tweaks, but still no luck with either modded gdmd or gdc.

Let's have a look at the offending file:

gdc -m32 -save-temps -c sample.d

This should generate a sample.s, where the lines 10, 86 and 93 are looking strange.

Thanks for your help... sorry I'm not responding quicker- I haven't had much time to devote to this issue.  Here are the results.  They don't mean much to me- I haven't bothered learning x86 assembly yet.

It seems like the -m32 has been lost in the tool chain. test.s is 32bit but the compiler seems to use the 64bit assembly driver...

#
# gdc -v -m32 test.s -o test -lm -lgcc -lpthread -lgphobos -L/where/ever/gphobos/is
# ./test

The above should succeed and print:

#

If that fails - most likely the "--32" in the "as" line is missing - it is a GDC bug.

The following should always succeed:
#
# gcc -v -m32 test.s -o test -lm -lgcc -lpthread -lgphobos -L/where/ever/gphobos/is
# ./test

You are correct: the gdc -m32 -v was lacking the --32 on the as line.  The direct GCC invocation worked correctly.

Who is maintaining GDC these days that I might contact?

Thanks a ton.

Try:
#
# gdc -m32 -Wa,--32 test.d

Please use the usuall bugzilla.

Hi Guys,

Not sure if this is still actual, but one solution is to invoke gdmd like this:

setarch i386 gdmd a.d ... etc

(I am working with a couple of test cases John sent me the other day to study the interoperability of D and the Zero Debugger and ran into  the same issue -- setarch seems to help the compiler driver to pick the correct toolchain)

Cheers,
Cristian
