problems compiling on 64-bit linux

[Jonathan Mukai]

Hi there!

I'm trying to compile Self on Debian Wheezy 64-bit but I'm running into a
few issues.

I can run `cmake .` in the self dir and get:

-- The C compiler identification is GNU 4.7.2
-- The CXX compiler identification is GNU 4.7.2
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works

-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works

-- Detecting CXX compiler ABI info - done
-- The ASM compiler identification is GNU
-- Found assembler: /usr/bin/gcc

-- Using X11 plaform windows.
-- Configuring for build level optimized

But then when I run `cmake --build .` I get...

Scanning dependencies of target makeDeps
[  1%] Building CXX object
vm/CMakeFiles/makeDeps.dir/build_support/makeDeps.cpp.o
Linking CXX executable makeDeps
/usr/bin/ld: skipping incompatible

collect2: error: ld returned 1 exit status
make[2]: *** [vm/makeDeps] Error 1
make[1]: *** [vm/CMakeFiles/makeDeps.dir/all] Error 2
make: *** [all] Error 2

It seems like ld is not getting the -m32 flag and is looking for libstdc++
in the wrong place, but I'm totally new to C++ so this is just my guess
from poking around.

I also tried running the binary from selflanguage.org but I get the
following error:

Self: error while loading shared libraries: libXext.so.6: cannot open
shared object file: No such file or directory

I have the packages libxext6 and libxext6-dbg installed, so I assume this
is another 32-bit/64-bit mismatch, but again, I'm not really sure.

Any ideas about what I can do to get Self running on my machine?

Thanks!

Johnny
