Seems my last reply was too large. Sorry about that.

Well, if it's a problem with my system, then it's a problem with all the
latest versions of Linux Mint 19 Cinnamon 64-bit. I've tested the code on
another Linux Mint install and I get the same error.

wmluiltok.c is not empty and contains a proper Flex scanner.

I guess I'll have to do what you suggest above. Just to make sure I
understand, I need to build the latest version of Flex from the source and
make sure to include the "-ffat-lto-objects" option to GCC? When you say
"allowing to use lto also on motif" what do you mean exactly? Do I have to
compile Motif from the sources in the archive and supply the same option to
GCC as you suggested above?

EDIT : After I typed the above, I compiled GNU Flex with the
-ffat-lto-objects by modifying its configure.ac to get it to supply the
option to GCC and then I tried compiling the Motif source that comes
packaged with RPL/2 ( I also had to modify configure.ac ). Although your
suggestions seem to have cleared up the previous problem with wmluiltok.c,
I now get a new error :

http://www.mediafire.com/file/v7wwlc8tuen6bt2/make-log-error-paste-1.asc/file

I resolved the above just by issuing an "apt update && apt install libfl2"
command and rebuilding the source.

EDIT 2 : Well, this time all the X Windows and Motif related code built
fine, but then the build failed with a new error :

http://www.mediafire.com/file/hhx46jxfh3l39je/make-log-error-2.asc/file

It looks like the main RPL/2 configure script is not calling the zlib
configure script. When I manually corrected that, I got a new error when
trying to compile zlib :

"
cc -shared -march=core2 -O2 -pipe -ffat-lto-objects -D_LARGEFILE64_SOURCE=1
-o libz.so.1.2.11 adler32.lo crc32.lo deflate.lo infback.lo inffast.lo

gzlib.lo gzread.lo gzwrite.lo  -lc
/usr/bin/ld: deflate.lo: relocation R_X86_64_PC32 against symbol
`_length_code' can not be used when making a shared object; recompile with

collect2: error: ld returned 1 exit status
Makefile:282: recipe for target 'libz.so.1.2.11' failed
make: *** [libz.so.1.2.11] Error 1
"

I added "-fPIC" via the usual environment variables but that didn't fix the
build failure. I next modified the zlib Makefile.in and that fixed the
problem. Then I restarted the RPL/2 build and it finally built! :D After
running "sudo checkinstall"  and installing the package I was able to "run"
"rpl -i" but it exited with the error :

I then removed the Debian package and I used the old school "sudo make
install" and guess what, it now works! :D
