Hi PCB developers,
I've been working on an automated installer for the entire gEDA Suite,
including PCB. PCB has a couple of pre-requisites which make it not
install cleanly on a stock "Red Hat 9 Professional" installation,
which is one of my target platforms.
Specifically, PCB has two issues:
1. It needs wish, which is part of Tcl/Tk. Configure fails when it
doesn't find wish. Ummm, I am not a PCB expert. Why does it need
wish?
Tcl/Tk is not installed as part of a vanilla RH9 Pro
installation. Don't ask me why. . . . .
Note that I have fixed this problem by checking for Tcl/Tk as part of
my installation process, and installing it if necessary. No action is
needed on your part.
2. PCB's docs need TeX/LaTeX to convert the .texi docs to .pdf and
.dvi. RH9 doesn't install TeX/LaTeX as part of a vanilla install.
Again, don't ask me why; I'm just (writing) the installer.
I have fixed this problem by putting checks into PCB's configure.in
and Makefile.am which look for a tex installation, and then just don't
build the docs from .texi files if tex is missing. I've tested this
stuff on my RH9 box and it seems to work. Please find these patches
below. Feel free to test them and include them into PCB.
Thanks,
Stuart
