Hi Theo,
Thanks for sharing that! I had I similar problem and wanted to share what I
arrived at.
If there is a C-compiler on the target, you could compile to .c or even .o
and link on the target side. Unfortunately, that needs fiddling a bit
around with compiler and linker flags.
Another solution is to compile the static chicken as a static executable.
-static to csc makes it compile the Chicken runtime (so no libchicken.so)
and eggs in statically. But you can tell gcc to take it a step further and
link statically as well (-L -static). This will grab libc and friends from
your build machine. Sometimes that might work and requires very little
fiddling around with compiler flags.
csc -L -static -static mymod.scm
