Compiling ZSNES 1.51 under 64-bit Linux

[jdb2]

I'm running Linux Mint 9 Isadora KDE 64-bit and want to run ZSNES via cross-compiling to 32-bit.

I've set up my environment like so :

( from 'env' )

Code: Select all

CFLAGS=-m32 --sysroot=/home/jdb2/sysroots
CXXFLAGS=-m32 --sysroot=/home/jdb2/sysroots

( the above are exported )

where 'ls -al ~/sysroots' produces :

Code: Select all

jdb2@aleph1 ~ $ ls -al ~/sysroots
total 12
drwxr-xr-x  3 jdb2 jdb2 4096 2010-11-29 05:52 .
drwxr-xr-x 84 jdb2 jdb2 4096 2010-11-29 05:11 ..
drwxr-xr-x  2 jdb2 jdb2 4096 2010-11-29 05:52 usr

and 'ls -al ~/sysroots/usr' produces :

Code: Select all

jdb2@aleph1 ~ $ ls -al ~/sysroots/usr
total 8
drwxr-xr-x 2 jdb2 jdb2 4096 2010-11-29 05:52 .
drwxr-xr-x 3 jdb2 jdb2 4096 2010-11-29 05:52 ..
lrwxrwxrwx 1 jdb2 jdb2   13 2010-11-29 04:58 include -> /usr/include/
lrwxrwxrwx 1 jdb2 jdb2   11 2010-11-29 04:58 lib -> /usr/lib32/

I've successfully built 32-bit applications that made heavy use of the gcc '-l' directive with the above with no issues.

I had to modify the configure file for a 32-bit build. Here is the patch after issuing an 'autogen.sh --prefix=/usr/local/zsnes' in the virgin source tree :

Now, one would think that ZSNES would now compile, or at least configure, but it doesn't.

Issuing a './autogen.sh --prefix=/usr/local/zsnes' in the modified source tree produces the following :

configure: error: SDL >= 1.2.0 is required

Looking at the config.log you can see the problem :

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.65.  Invocation command line was

I am at a lost as to why the linker is looking for the x86-64 libs instead of the libs in /usr/lib32 since I have eliminated all references to /usr/lib where it counts.

Does anyone have any ideas?

Are you sure you have the 32-bit SDL libraries installed?

[jdb2]

Are you sure you have the 32-bit SDL libraries installed?

Yes. I have the ia32-libs package installed so the 32-bit version of the SDL libraries should have been installed when the 64-bit version was installed and indeed they were. If I do a 'ls -al /usr/lib32/*SDL*' I get :

Really, I have no clue why it is looking at the x86-64 libs.

I'm no expert, but have you looked at this thread:

I have, but thanks for reminding me.

The problem is that I'm having a link-time error as opposed to a run-time/dynamic-link-time error as described in the thread.

The thread is relevant to my other post about installing the i386 package though. In that case the package has a libao4 1.0+ dependency which I can confirm by doing an ldd on the zsnes binary :

Code: Select all

I can confirm that libao.so.4 is 32-bit ( because I built it myself ) :

Code: Select all

jdb2@aleph1 ~ $ file /usr/lib32/libao.so.4
/usr/lib32/libao.so.4: symbolic link to `libao.so.4.0.0'
jdb2@aleph1 ~ $ file /usr/lib32/libao.so.4.0.0
/usr/lib32/libao.so.4.0.0: ELF 32-bit LSB shared object, Intel 80386, version 1 (GNU/Linux), dynamically linked, not stripped

but I have no plugins-2 directory; instead a plugins-4 directory and there is no libalsa09.so in there even when I build and install libao4 with --enable-alsa. Hmmm... maybe that's the problem. As I state in my post, the installed zsnes binary with all dependencies installed segfaults -- a missing or mismatched dynamic library as all that I can think of as the cause right now.

Really, there is no point on compiling it yourself.

Use the experimental binaries in this thread:
