Digital Mars - D.gnu - AMD64 Linux

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: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.

Any suggestions?

I don't remember seeing those error messages.

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

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.

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...

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

 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...

 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
 # > Hello

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
