Discussion list for gdb, the GNU source debugger

Sorry, a dumb one: how do I BUILD the thing (i.e. gdb) on Win?


Hello,

I'm sorry, this one will probably make you cringe... but I'm one of the poor
guys running Windows (Win7-64).

I managed to install a perfectly running MinGW64, and it's frankly a marvel
in squeezing whatever juice there is in the machine (I'm in some very heavy
number crunching).
But now I seem to have a bug somewhere, and the only way for me to find out
what happens in the 64bit executable seems to be to run it in gdb. I
downloaded gdb-7.3.1.tar.gz and extracted it ok... but then what should I do
to produce a gdb.exe?
All the doc and commands appear to be targeting Unix (e.g. "./configure"
does of course nothing at all in Win) and unless I have missed something
big, it's not even clear to me which Makefile I should pass to make.

Is there a reasonably clear "roadmap" for building gdb in Windows?

Many thanks for your kind help!

Emanuel

Hello again,

I actually managed to find an already built gdb.exe. It's
This GDB was configured as "x86_64-w64-mingw32".
which not only means that it can indeed load Win-64 images, but also that it
IS possible to build gdb with MinGW64. 

I found it at http://www.equation.com/servlet/equation.cmd?fa=gdb . I have
to confess that downloading a plain .exe and running it on my machine was
pretty scary - if anybody could confirm that downloads from equation.com are
virus-free, it would be greatly appreciated.

Another downside is that it's 7.2, while the latest official gdb release
seems to be 7.3.1 - another reason to try and build it myself.
But anyway, it seems to be running ok... and I found my bug! 

Greetings and Merry Christmas,

Emanuel

Luck to find something pre-built.

I would think that using Cygwin would make life a little easier.

I would not get too distressed about that. 7.2 is likely mature enough for 
most  things you'd want to do under x86.

I think there is pre-build version of gdb for windows. Your definitely will need more effort if you want to build your own.
