Look at dmd.conf. It includes several flags which are supposed to be
passed to the linker - either that or you can use dmd to link rather
than using gcc on its own. Personally, I wouldn't bother compiling and
linking as separate steps, but if you do, you need to make sure that
you either use the flags in dmd.conf or you link with dmd rather than
gcc. For the most part, there's no reason to link with gcc, even if you
want to link separately. - Jonathan M Davis
Hmm.. after linking with all the options in dmd.conf (-L/usr/lib32
-L/usr/lib64 --no-warn-search-mismatch --export-dynamic -lrt), I still
get

Now, I compiled libdsfml-system.a myself, and I know they're 64-bit, so
this implies ld still isn't recognizing that I want 64-bit executables.
I think the reason that ld is skipping those libraries is that secretly,
inside the .a archives, they are really 32-bit libraries and not 64-bit
libraries.
You can confirm this by using the ar x {somelibrary}.z to extract the
object files (do it from a new temp directory), and then running file
{new}.o, which in my hands reports that the dmd libraries such as phobos
are actually 32-bit, even on x86_64 linux.
This is why I went to LDC2, which is fully 64-bit.

DMD2 - compiling and linking in separate steps (64-bit)
I'm trying to use DMD through an IDE, but I'm getting stumped trying to create 64-bit executables under Linux. I can get everything compiled fine, using the -m64 compiler flag, but I can't get it to link. Here's the error list: /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libphobos2.a when searching for -lphobos2 /usr/bin/ld: skipping incompatible /usr/lib/../lib/libphobos2.a when searching for -lphobos2 /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libphobos2.a when searching for -lphobos2 /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libm.so when searching for -lm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libm.a when searching for -lm /usr/bin/ld: skipping incompatible /usr/lib/../lib/libm.so when searching for -lm /usr/bin/ld: skipping incompatible /usr/lib/../lib/libm.a when searching for -lm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libm.so when searching for -lm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libm.a when searching for -lm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/../lib/libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/../lib/libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/libgcc.a when searching for -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/librt.so when searching for -lrt /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/librt.a when searching for -lrt /usr/bin/ld: skipping incompatible /usr/lib/../lib/librt.so when searching for -lrt /usr/bin/ld: skipping incompatible /usr/lib/../lib/librt.a when searching for -lrt /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../librt.so when searching for -lrt /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../librt.a when searching for -lrt /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libc.so when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../../lib/libc.a when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/../lib/libc.so when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/../lib/libc.a when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libc.so when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux- gnu/4.4.5/../../../libc.a when searching for -lc collect2: ld returned 1 exit status How do I use ld to link 64-bit D executables?
