RC and GDB Blues

RC and GDB Blues

[Mark K. Gardner]

Hello all,

I am having trouble running gdb with rc 1.5betadev on Solaris 2.5.1
either from the command line or from within emacs. When I run from
tcsh, gdb works fine. I am at a loss for where to start looking for
the problem. Hints anyone?

I've run it on Solaris 2.5.1, and didn't see tha tproblem.

But speaking of 1.5betadev, anyone think the glob routines should (via
a run time switch) work on utf-8?  Then 9term and sam users can fully
break with 8859-1.

What's needed to make the shell utf8-savvy?  I supposed it's just ? and
[chars] that don't work right, right?

Yes.

I have discovered the problem. rc is not installed in /etc/shells and
hence I cannot have it as my login shell in /etc/passwd (tcsh is). I
instead "exec rc -l" from .tcshrc. GDB executes a program under the
shell specified by the SHELL variable (i.e., which was tcsh in my
case), which causes .tcshrc to be read, which causes "exec rc -l",
which causes a SIGTRAP. Adding "SHELL=<path to rc>" to .rcrc cured the
problem.

Did you compile with -lbsd?
