If it isnt going to effect other builds, we could just unset in in the makefile like a group of other env vars already are

Is there anything we need to do in the MXE configuration to resolve this report ahead of the 5.1 release?  Or is this just a note for users of OpenSuSE, in which case the bug can be closed, but will always be searchable.

Thanks to you both. I confirm that a full build ran fine after unsetting CONFIG_SITE, and --enable-lib64-directory had not to be used. A directory usr/lib64 was still created but it didn't seem to be an issue.

ls mxe-octave/usr/lib64
libcc1.la  libcc1.so  libcc1.so.0  libcc1.so.0.0.0

I had added
unexport CONFIG_SITE

in Makefile.in and it got past gcc for me and only has a usr/lib directory, so that looks like its probally it

On SuSE Leap 15, this lib64 choice appears to be happening because of the config.site file that is installed by default.  My environment had a CONFIG_SITE variable set that caused it to be used.  So instead of configure defaulting to libdir=${exec_prefix}/lib, it was set to ${exec_prefix}/lib64.

I unset CONFIG_SITE and started a new build.  I'll report back when it finishes.

If I get some spare time, I'll try openSUSE and take a look

Not using --enable-lib64-directory returns the same error with libraries still to be found in usr/lib64.

It seems to be a frequent issue with openSUSE. In the link below, it says that there would be a similar issue on Mac:

Maybe the issue is the --enable-lib64-directory. The only time I have used it was when building a native version of octave in mxe.

I havent tried suse, just fedora and ubuntu, on both my configure is:

./configure --enable-devel-tools --enable-windows-64=yes --enable-octave=stable --enable-64 --enable-binary-packages

Looking at the build, there is then only the lib, not a lib64 directory under usr

Yes, I use:

./configure --enable-octave=stable --enable-binary-packages --enable-devel-tools --enable-qt5 --disable-system-opengl --enable-windows-64 --enable-64 --enable-lib64-directory

With this, one gets an error when building gcc-cloog:

/usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/ld: cannot find -lisl

All the libraries are in usr/lib64 but looking at log/gcc-cloog:

checking our pkgconfig ldflags... -L/tmp/mxe-octave/usr/lib

If one creates a symbolic link lib -> lib64, cloog is successfully build but there will be further issues down the line with gcc.

Did you try the --enable-lib64-directory option when running configure ?

I am trying to build mxe-octave on openSUSE 15.0 and I come across a number of issues due to the fact that the built libraries are stored in usr/lib64 while they seem to be expected in usr/lib. Adding a symbolic link between them before the beginning of the built of any library allows me to proceed further (`mkdir usr; cd usr; ln -s lib64 lib`).

Other errors occurs later on due a similar issue with usr/x86_64-w64-mingw32/lib vs usr/x86_64-w64-mingw32/lib64 but it's harder to deal with as both directories are used and symbolic links become replaced by hard links when a built package installs its libraries.

This would mean that different packages use a different strategy to define where libraries are stored (/usr/lib vs /usr/lib64) for which openSUSE returns different answers. I could find a related discussion here:
