AXIOMsys provides core functionality. FriCAS uses pseudoterminals
to have nicer user interface. ptyopen is in src/lib/openpty.c, on
Mac OS X 10.4.x it should simply call openpty from Mac libraries.
Things to to check:
- does the config/axiom-c-macros.h file in build directory contain
lines like:
#define HAVE_OPENPTY 1
#define HAVE_OPENPTY_DECL 1
If no then FriCAS cannot find files needed for compilation of
C programs -- one should look into config.log for more details.
- what is return value from ptyopen call (it is supposed to return
-1 or exit in case of failure). Note: if answer to previous
question is negative then FriCAS will use it own code for
opening pty -- AFAIK this code is not going to work on Mac OS X 10.4.x,
but it should properly report failure.
