#35 gdb and python problem

[owlcn]

I use pacman install mingw-w64-i686-gdb, run gdb and get error message:

Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site

When I set $PYTHONHOME=/mingw32/lib/python2.7, I get the error message:

ImportError: No module named site

How can I solve this problem, thx

Provide more info. I don't have this error. How you start GDB - from MSYS or from CMD? Does mingw-w64-i686-python2 installed?

[owlcn]

start gdb from MSYS2(mingw32_shell.bat),mingw-w64-i686-python2 installed.
I test in 2 pcs,win7 x64 and xp sp3,both problems.

[owlcn]

pacman -Sl info in txt file.

[Alexx83]

I see what is wrong :)
You need update packages to latest. Just run:
pacman -Syu

Regards,
Alexey.

I start gdb in CMD, no error info output, working properly.
but in MSYS2, error again.

[Alexx83]

Do you restart MSYS2 after packages upgrade? If no then do it.

[owlcn]

I have upgrade all packages,and run autorebase.
But still have a problem.

Help,please~

Do you have done weird environment variables set? PYTHONHOME etc?

Show output of "printenv" command please

[LiTuX]

I know this issue, in my msys, running gbd from bash or cmd lead to the same result:

Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site

In my case, I've set the environment variable to solve the problem: export PYTHONHOME=/mingw32 is enough.

[Alexx83]

I think that it about your environment because I and some other peoples don't have this issue.
Show "printenv" output

[owlcn]

export PYTHONHOME=/mingw32

@LiTux,working,thx very much~~~

env int txt file,please check.

[Alexx83]

Does this issue still happened?

[David Macek]

Closing due to age, hopefully fixed by now.

If not, just call export PYTHONHOME=c:/msys64/mingw64/;c:/msys64/mingw64/share/gdb/python before calling gdb.
