Liberoffice installation and Python issue...

Hi,

I am trying to install Libre-Office-5.2.4 from source on ubuntu, and getting issue for Python. for this I have installed Python using source-code in /opt/Python3.6 directory, here is the outcome of /opt/Python3.6

$ ls -l /opt/Python3.6/
total 16
drwxr-xr-x 2 root root 4096 Dec 26 16:45 bin
drwxr-xr-x 3 root root 4096 Dec 26 16:24 include
drwxr-xr-x 4 root root 4096 Dec 26 16:45 lib
drwxr-xr-x 3 root root 4096 Dec 26 16:45 share

when i try to configure office for installation it fail to find Python.

libreoffice-5.2.4.2$ ./configure --with-python=/opt/Python3.6/

configure: error: Python headers not found. You probably want to set both the PYTHON_CFLAGS and PYTHON_LIBS environment variables

for the above error i have already set the env variables

libreoffice-5.2.4.2$ echo $PYTHON_LIBS
/opt/Python3.6/include/python3.6m

libreoffice-5.2.4.2$ echo $PYTHON_CFLAGS
/opt/Python3.6/include/python3.6m

/libreoffice-5.2.4.2$ ls -l /opt/Python3.6/include/python3.6m/Python.h

I guess setting variables don't cut her. Have a look at the top part of the libreoffice configure script see if you can set (change) the desired directories there.

Something that worked well for me in the past, when I needed to inject all necessary files in their proper place for booting up with the necessary proprietary graphics drivers enabled (Nvidia,AMD) if a supported chip was detected during early bootup on a Debian live system. I would do a mock install of Nvidia to see what would get installed, downloaded the packages and had a look inside to see what all files it had and where they would go.
I had placed the files in /root and had my own compliant boot script that pumped the files in place at the right time and the OS would automatically have proprietary video support for either make of card automatically.
Maybe try this with your package manager and see if you can place the necessary files from your build in the directories other applications would look for them, might save you a lot of headaches in the long run.

Moved: This thread is more suitable in <Ubuntu> and has been moved accordingly to help your thread/question get the exposure it deserves.

I'd highly recommend rolling custom packages for both Python and LibreOffice. That will save a lot of trouble, such as some of what you are encountering already. Mixing and matching manually installed packages almost never works out well, and will always be a lot of effort. You can get the source packages for both python and libreoffice using apt-get:

mkdir /tmp/scratch/ && cd /tmp/scratch/
apt-get source libreoffice python

From there you'd substitute in the new source code. There's obviously more to it than just that, but you can find many tutorials and guides on the topic for Ubuntu or Debian. Both apply, at least until snappy is fully deployed in Ubuntu. Which version of Ubuntu?

What is in your /opt/Python3.6/include/ directory? It's possible that you may need to do this

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

to install the correct header files.

i have moved the liberoffice to parent-directory... and this solved the issue...of ./configure but now when i do compilation it fails with new error message.

I fixed this by installing the libpython3-dev package.

(Note, I already had the libpython-dev installed.)
