Re: Compiling the latest GDB on cygwin

[Jingzhao Ou <jingzhao.ou@gmail.com>]

Hi, Dave,

I got GDB compiled successfully! The problems for the undefined
symbols are because I do not have yacc installed the first time I
tried to compile GDB. I removed all the source files, make sure that
yacc is installed, and compiled from the scratch. Then, things work
properly from there. However, I would suggest the "configure" script
be improved to detect "yacc" properly. It is kind of tricky for the
current version.

I want to make some contribution. Currently, Insight ships with its
own version of tcl/tk. Also, it still relies on libgui. Could you
comment on the possibilities and the amount of work required if I want
Insight to build based on the official tcl/tk and to remove its
dependence of libgui?

Thanks a lot for your wonderful help! 

Best regards,
Jingzhao
