Re: [Libguestfs] Issue with python pip install

Richard,

Thanks for fast reply - let me remove all the yum packages and then
build/install from single version.

Regards

John

I would avoid using 'make install' in the libguestfs git repo.

A better plan may be to roll back the git repo to match the version of
libguestfs you have installed (from yum), eg:

  git reset --hard 1.28.1

then try the pip method again.

Re: [Libguestfs] Issue with python pip install

Richard,

It is looking better, but still getting error - see attached log.

I removed all installed packages and yum installed libguestfs
libguestfs-devel (1.28.1)

Then reset my git repository to 1.28.1 and then

$ make clean
$ ./autogen.sh --disable-erlang --disable-perl --disable-lua --disable-ruby
$ make
$ make -C python sdist
$ cd python/dist
$ sudo pip install guestfs-1.28.1.tar.gz

Regards

John
