Compiling Xen error on RedHat8.0

Compiling Xen error on RedHat8.0

[Chen, Farrah]

Hi,

I met some python related issues when building Xen on RedHat8.0.
On RedHat8.0, the default python version is python3, and I found Xen has some python2 codes, so I tried to build xen using python2.
On RedHat8.0, no "python", just "python2" and "python3":

ls /usr/bin/python*
/usr/bin/python2    /usr/bin/python2.7-config  /usr/bin/python3    /usr/bin/python3.6-config  /usr/bin/python3.6m-config         /usr/bin/python3-config
/usr/bin/python2.7  /usr/bin/python2-config    /usr/bin/python3.6  /usr/bin/python3.6m        /usr/bin/python3.6m-x86_64-config

So I created a soft link "python" to "python2":

ll /usr/bin/python
lrwxrwxrwx 1 root root 16 May 24 13:08 /usr/bin/python -> /usr/bin/python2

Then I tried to build xen:

cd xen
./configure --enable-ovmf
.........
checking for unistd.h... yes
checking for python-config... no
checking Python.h usability... yes
checking Python.h presence... yes
checking for Python.h... yes
checking for PyArg_ParseTuple... no
configure: error: Unable to find a suitable python development library
configure: error: ./configure failed for tools

If I use python3(create a soft link "python" to "python3" ), it reported syntax error.

checking for unistd.h... yes
checking for python-config... no
  File "<string>", line 1
    import distutils.sysconfig;         print "-I" + distutils.sysconfig.get_config_var("INCLUDEPY")
                                                 ^
SyntaxError: invalid syntax
checking Python.h usability... no
checking Python.h presence... no
checking for Python.h... no
configure: error: Unable to find Python development headers
configure: error: ./configure failed for tools

To resolve "Unable to find a suitable python development library", I installed python2-devel*, python2-lib*, python3-devel*, python3-lib*, python2-six, python3-six, but this error still exists.
In RedHat7, these packages are called "python-devel*, python-lib*", but in RedHat8, these packages don't exists, RedHat8 has only "python2-devel*, python2-lib*, python3-devel*, python3-lib*", maybe Xen codes cannot identify them.

Do you have any advice on building Xen on RedHat8? Thanks a lot!



Thanks,
Fan

If you want to go down the python3 path there are a bundle of python3 
packages (from the xen master branch) in the Fedora build of xen-4.12.0 at
https://src.fedoraproject.org/rpms/xen/blob/master/f/xen.python3.patch
which might be useful to apply or refer to given that RHEL 8 is loosely 
based on Fedora.

Also RHEL 8 has python36-devel and python2-devel which you might need for 
a python3 or python2 build.

If you're building a release of Xen, then you could try setting
PYTHON=/usr/bin/python2 everywhere, that is when starting configure and
make, something like:

$ ./configure PYTHON=/usr/bin/python2 ...
$ make PYTHON=/usr/bin/python2 ...

If you are building from the unstable tree, I think we fixed most of
those bugs relating to python2/python3.

Is that help?

About the soft link "python" to "python2", you would need a softlink
"python-config" to "python2-config" as well and the "checking for
PyArg_ParseTuple" is more likely to succeed.

Hi Anthony,
