Anyway, I tried the latest flext source on Windows, and it builds in
msys2 (using the autoconf build system, i.e. ./bootstrap; ./configure;
make) but only produces static libraries there. That’s all I can say
right now, I didn’t yet try to build anything against it.

Well, I was finally able to build disis_munger~ against the latest flext
and stk sources. I just ignored all those crazy flext build scripts (which
don’t work in msys anyway) and rolled my own Makefile (attached) by
gleaning all the compile options from the Linux build scripts. It’s
compiling and linking fine, using the static flext and stk libraries.

The external loads but it crashes Pd immediately (both latest Vanilla and
Purr), with this message from the rt engine:

free(): invalid pointer
Pd: signal 6

gdb backtrace (running in vanilla):

Same on Linux and Windows. Ico, it looks like disis_munger~ needs some
tender care by someone who knows flext better than me. ;-)
