I've just compiled
gdb 7.8 from source in my home directory on a server machine running linux. I had previously been using
gdb 7.6, and aside from stability issues with
gdb itself (the reason for the upgrade) everything worked fine.
Since the upgrade of
gdb, when I run
cgdb 0.6.7 I immediately get the following message:
Python Exception <type 'exceptions.ImportError'> No module named gdb: warning: Could not load the Python gdb module from `/home/username/bin/gdb//python'. Limited Python support is available from the _gdb module. Suggest passing --data-directory=/path/to/gdb/data-directory.
When I built
gdb, I used
When I run
cgdb and my program reaches a segfault, I type
backtrace and get the following message:
Python Exception No module named gdb.frames:
So it seems like I am effectively unable to use
cgdb without python support. What can I do to resolve this?
FWIW; I don't use
python, I usually write
You should specify the value of "
--data-directory". For example, if you load
gdb from the build directory, the command should be:
./gdb -data-directory ./data-directory
gdb can know where to find

I just ran into this and wanted to share what i found. During compilation, specifically the 'make install' step, i noticed a messages saying this:
WARNING: `makeinfo' is missing on your system. You should only need it if
you modified a `.texi' or `.texinfo' file, or any other file
indirectly affecting the aspect of the manual. The spurious
call might also be the consequence of using a buggy `make' (AIX,
DU, IRIX). You might want to install the `Texinfo' package or
the `GNU make' package. Grab either from any GNU archive site.
It sounds as if it's OK that I don't have makeinfo, but in fact it led to the error that the OP asked about. When I installed
texinfo I then reinstalled
make install and ran gdb with no python error message.
just to complete the above responses:
Probably you have copied the executable gdb to
/usr/local/bin (which is my way to prioritize the lastest gdb that I installed as default shell gdb, while preventing messing up with the default Ubuntu's gdb). Then you should consider that you must give the data-directory parameter from the original place to the one that you have copied in
/usr/local/bin. So that would be:
PS: I did this for gdb-8.1 on Ubuntu 16.04
