Hi there,

I've been using D for a while now, but only on Windows, and I'm currently trying to get my project to compile on Mac OS X. I'm pretty new to Macs, in general.

The machine is a classic iMac, one of the original ones from 1998; I think it's a Revision B. (My workplace was going to throw it out so I got it for free.) I installed a fresh copy of Mac OS X 10.3 "Panther" on it (Tiger dropped support for the classic iMacs), downloaded and installed Xcode Tools 1.5 as instructed, and then downloaded and installed gdc from http://gdcmac.sf.net.

To test it I created a simple D file, like this:

void main() {
}

I tried to compile it (using either gdc test.d or gdmd test.d) and got this:

$ gdc test.d
ld: Undefined symbols:
_acosl
_asinl
_atan2l
_atanl
_cbrtl
_ceill
_copysignl
_coshl
_erfcl
_erfl
_exp2l
_expl
_expm1l
_fabsl
_floorl
_frexpl
_ilogbl
_ldexpl
_lgammal
_log10l
_log1pl
_log2l
_logbl
_logl
_modfl
_nanl
_nearbyintl
_powl
_remainderl
_roundl
_sinhl
_sqrtf
_sqrtl
_tanhl
_tgammal
_truncl

I have no idea what's causing this. I've tried reinstalling Xcode and the BSD Subsystem, to no avail.

Any ideas?

Thanks in advance!

Sounds reasonable. The math symbols you describe are being defined in /usr/lib/libSystem.dylib, so it should be able to find those easilly...

It works here, Mac OS X 10.3.9, Xcode 1.5. So it should for you too.
Which GDC installation for Panther did you use ? (i.e. 0.19 or r20)

PS. You might try installing GDC from source code to see if that helps

That's what I thought too...

I used 0.19.

I'll look into that, thanks for the suggestion.

OK. *scratches head*. That is the one I've used most.

If you run with gdc --verbose it'll show all the steps,
and if you run it with ktrace it'll dump a ktrace.out:

gdc --verbose -c test.d 2> test.out
ktrace gdc -c test.d

Email those two outputs to me, and I'll have a look...
(zip the test.out and ktrace.out up in an archive or so)

Probably more interesting if we include the linker step too:

gdc --verbose -o test test.d 2> test.out
ktrace gdc -o test test.d

BTW; you can view the ktrace.out using the "kdump" command.

I sent you test.out and ktrace.out.

By the way, I should mention that my system isn't quite the same as yours. I'm not running OS X 10.3.9; I think it's 10.3.0 (all the version numbers I can find just say "10.3"). I suppose upgrading would be a good idea...

A very good idea, as it turns out. Upgrading to 10.3.9 solved the problem.

Thanks for your help Anders!

Okay, explains why I couldn't reproduce or find anything.

I think I will maybe post a "warning" on the gdcmac site.

Yes, good idea. I was going to suggest that but forgot. :-)

Probably could have made a version with the MacOSX10.3.0.sdk,
but it's better to force upgrading to 10.2.8 and 10.3.9... :-)

Besides, you probably *want* Mac OS X 10.3.9 anyway for the
security fixes, and for the compatibility with GCC/G++ 4.0 ?
