Seems to be a trivial ordering problem in the makefile. And there are missing references to symbols from -lm and -lstdc++.

Using GCC-4.5 to build from source.

The linux.mak line is:

dmd: $(DMD_OBJS)
        gcc $(MODEL) -lstdc++ -lpthread $(COV) $(DMD_OBJS) -o dmd

which doesn't match your --- dmd~/linux.mak. So I am wondering where your linux.mak came from.

Created an attachment (id=847)
make log

Ah, probably serves me right for manually changing it back before making that diff. I still stand by the ftbfs though.

Unzipped dmd2050, and attaching output of 'gcc $(MODEL) -lstdc++ -lpthread
$(COV) $(DMD_OBJS) -o dmd'

Changing

gcc $(MODEL) -lstdc++ -lpthread $(COV) $(DMD_OBJS) -o dmd

to

gcc $(MODEL) $(COV) $(DMD_OBJS) -lstdc++ -lpthread -o dmd

Yields:

/usr/bin/ld: evalu8.o: undefined reference to symbol 'fetestexcept@@GLIBC_2.1'
/usr/bin/ld: note: 'fetestexcept@@GLIBC_2.1' is defined in DSO /lib/libm.so.6
so try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [dmd] Error 1


Hence the added -lm

Seems to be OK now. Probably fixed through some part of the binutils updates I've been seeing recently.
