It is not completely clear (to me) what exactly fails / is wrong in 
your case. If the following is not enough to solve the problem, please 
be more specific.

Although the exact error message might vary, please consider whether 
the problem / workaround / solution is covered by:

 http://www.syslinux.org/wiki/index.php/Filesystem#ext 

and/or by:

 http://www.syslinux.org/wiki/index.php/Building 

and/or by:

 http://www.syslinux.org/archives/2017-February/025531.html 

and/or by current git master head:

 http://repo.or.cz/syslinux.git 

Please also note that versions/builds of all Syslinux-related binary 
files shall match. A mismatch between bootloader file and c32 module(s) 
shall be avoided.

There are additional potential conflicts, but see whether the above 
points are enough for you case/needs.

Regards,
Ady.
