Re: DMD on x86_64
tried the your approach it worked but compile cpp applications fails. [Sanity Checks - fails] i found my way arround it by installing cross32-gcc and adding CC=/usr/bin/i686-unknown-linux-gnu-gcc to the dmd.conf file I have added the procedure to Wiki4D http://www.prowiki.org/wiki4d/wiki.cgi?D__Tutorial/StartingWithD/ Compiler/DMD#ArchLinuxASaferSolutionD

Re: DMD on x86_64
Hello Brad, The other thing you could try is to take dmd out of the loop. Can you build a 32 bit c/c++ app with gcc/g++ directly? If you can't get that to work, it's unlikely that dmd will we successful either, given that it relies on gcc to invoke the linker, picking up all the right c library pieces. if all else fails, you could use dmd -c and invoke the linker directly. -- ...

Re: DMD on x86_64
If you manage to find the proper 32 bit libraries, there is a configuration file for ld where you can specify the search paths, should be: /etc/ld.so.conf The 64-bit distro's I have used fail to add the 32-bit lib paths to this file, even if you install the right packages.

The paths to my 32bit libs seem to be in there, thanks :)

I have a 32 bit version of libpthread in /opt/lib32/lib, so I then tried:

ld still seems to be trying to use the 64 bit version. Trying to link
manually with gcc (some options tweaked):
% gcc test.o -o test -m32 -Xlinker -L./../lib -L/opt/lib32/lib
-L/opt/lib32/usr/lib -lphobos2 -lpthread -lm
/usr/bin/ld: skipping incompatible /lib/libpthread.so.0 when searching
for /lib/libpthread.so.0
/usr/bin/ld: cannot find /lib/libpthread.so.0
collect2: ld returned 1 exit status
This seemed to get less errors than before. When I specified the path to
libpthread manually it started complaining about libgcc. Using -v with
the above command I found the linking command, then adapted that and
tried manually again, but was left with the error:
/usr/bin/ld: warning: cannot find entry symbol _start; defaulting to
08048c90
When editing the linking command I had to remove a selection of gcc
libraries that I don't have 32 bit versions of, which could be the
issue, however according to nm none of the other .o's or .a's that are
meant to get linked contain _start. Does anyone have any idea how I can
get dmd working with a multi lib x86-64 system? I'm using Arch Linux, if
you could point me in the right direction to get the missing libraries
or whatever's needed to get dmd working let me know, thanks.

Try typing:
export LD_LIBRARY_PATH=/opt/lib32
before compiling.

Re: DMD on x86_64
Don't forget that gcc adds a couple of system libraries (like libgcc) to the linker command. You need to give the right path for those too (you might want to try with --sysroot, or use --nostdlib and specify -lgcc manually) Jerome -- mailto:jeber...@free.fr http://jeberger.free.fr Jabber: jeber...@jabber.fr signature.asc Description: OpenPGP digital signature
