RE: Build problem on OpenBSD MIPS

 Hi John,

  it indeed seems to be that your build
doesn't use YACC debugging and that this could be the reason of the
unused function that generates the error.

You could:
1) delete c-exp.c in the build directory
and check how this file is regenerated by the make script.

a simple 
rm c-exp.y
make c-exp.y should be enough for this.

2) Test recompiling the new c-exp.c file
make c-exp.o
should be enough.

If you do get again the same error, you can 
bypass it simply by disabling the "consider a warning as an error" option
which is the -Werror option of GNU C compiler.

3)
To do this, simply run
make c-exp.o WERROR_CFLAGS=""

4) After that, a normal 
make gdb insight
should work.

If point 2) still fails,
it would be worthwhile to state that problem to [email protected]
specifying how c-exp.c was regenerated at point 1
(and the version of the executable used, which might well
be of importance here).

Hopefully you will be able to complete insight compilation...
