Home Page Forums MAME Non-Windows MAME Support Please help for compiling MAME on Slackware 15

Hello,

I've tried to compile MAME on Slackware 15 with gcc 11.2 that is its standard compiler.
Everything seemed to go well but then ld skipped a number of incompatible libraries.

It's my first compiling MAME so I'm indeed missing some information on the prerequisites to compile.
I know there is a maintainer for Slackware but seems to be unreachable.

The existing threads here seems to be outdated.
Any suggestions would be very appreciated, many thanks.

Can you paste the actual errors you're seeing? GCC 11 is a supported compiler, although probably not too many people use it now.

It's something like:

/usr/bin/ld: skipping incompatible <libname>.so.<number>

To paste the exact errors I guess I should run make again, it took three hours. I need to find that time again.

Unless I can just run ld but I don't know against which file(s).

Sorry, I'm a beginner

If you just run make again it should skip any work it's already done. Also, add the -jX parameter to make and it goes much faster. X is the number of CPU cores you want to throw at it (usually all of them that your system has, but if you want the machine to be usable while the make runs 1 or 2 less is a good idea).

This is the output:

About the first one:


bash-5.1$ locate libdl.so

/boot/initrd-tree/lib64/libdl.so.2
/lib/libdl.so.2
/lib64/libdl.so.2
/usr/lib/libdl.so
/usr/lib64/libdl.so

That feels like a 32/64-bit mismatch. I don't know how Slackware handles that but on Fedora there are separate 32 and 64 bit versions of each library and you have to install the 64-bit versions to build 64-bit MAME.

Thank you so much for inspiring me.

Setting LD_LIBRARY_PATH did the trick.

Great! Glad I could get you going.
