Q: How do I change the color scheme?
A: There are four color schemes available by default. They are classic
(Borland-like blue scheme), dark (set by default, black background,
etc), mc (inspired by Midnight Commander) and mono. To change a default
color scheme for all the Motor users in your system, you should modify
the /usr/local/share/motor/themes file and for a specific user,
~/.motor/themes. If it doesn't exist, just copy from /usr/local/share/motor.
To choose between default schemes, just modify the second line in the
file. "scheme <your preferred scheme name>", but if you want to create
your own scheme, look below in the file. Also the file named "syntax"
may be for interest in this case.
Q: I can't get out from a dialog or a menu. When I press ESC, nothing
happens.
A: Have you ever used mc (Midnight commander)? It requires users to
press ESC twice to close a dialog, menu, etc. It's not a problem, but
just a terminal specific issue.
Q: Motor compiles way too slow on my box. What's wrong?
A: C++ compiler optimization being a rather slow thing is on by default.
To turn it off, do the following.
[konst@morgue]$ CXXFLAGS=-O0 ./configure && make
Q: The following error message is displayed every time I try to build
the software. What's wrong?
/usr/bin/ld: cannot find -lcurses
collect2: ld returned 1 exit status
make[2]: *** [motor] Error 1
make[2]: Leaving directory `/home/me/motor/motor-3.0.0/src'
make[1]: *** [install-recursive] Error 1
make[1]: Leaving directory `/home/me/motor/motor-3.0.0/src'
make: *** [install-recursive] Error 1
A: You either miss an ncurses library or haven't got appropriate backward
compatibility links established. The latter is more possible. To fix
this issue the following commands from the root user:
# cd /usr/lib
# ln -sf libncurses.a libcurses.a
If this doesn't help, you do miss the whole ncurses library. Get it either
from your Linux distribution package or from
http://www.gnu.org/software/ncurses/ncurses.html
Q: Please explain how I do free a tty to use the gdb front end.
A: First, you can only use debugging locally. It means no ssh, telnet or
something. Motor must be ran in a local console.
Run this from root:
# for i in /dev/tty[0-9] /dev/tty1[1-2]; do fuser $i; done
At least one tty should be free, i.e. musn't be on the list which the
command displays. If it's not terminate a program running on a tty
you wanna use for debug. If it's used by a getty or something, remove
it from your /etc/inittab file.
Next, permissions. The free tty (not used by any program) should
allow you to write there. Check it the following way:
$ echo "test" >/dev/tty10
if you want motor to run on the 10th console. If you have a problem
with permissions, it says "permission denied". It can be corrected
with the following command (from root):
# chmod 666 /dev/tty10
Voila. Now you do have a free tty to use Motor's gdb front-end.
