Compile python 3.6 locally, with openssl and sqlite3 support

gistfile1.txt

Create a dir to build things into:

  $ mkdir ~/stack && cd ~/stack

Download the sources (sqlite 3230100 was broken, 3220000 was used instead):

  $ wget https://www.openssl.org/source/openssl-1.1.0h.tar.gz
  $ wget https://sqlite.org/2018/sqlite-src-3220000.zip
  $ wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz

Add paths in your ~/.bashrc so that when you'll compile python below, it'll find the just compiled programs:

  export PATH=$HOME/.local/bin:$PATH
  export LD_LIBRARY_PATH=$HOME/.local/lib:$LD_LIBRARY_PATH
  export MANPATH=$HOME/.local/share/man:$MANPATH
  export PKG_CONFIG_PATH=$HOME/.local/lib/pkgconfig:$PKG_CONFIG_PATH

Then enter into a computing node (!), and load the most recent gnu compiler:

  $ module load gnu

Sometimes, doing things too much in parallel (-j8) breaks tests. Try reducing it (-j4).

Compile openssl:

  $ tar xf openssl-1.1.0h.tar.gz && cd openssl-1.1.0h
  $ ./config --prefix=$HOME/.local/
  $ make -j8
  $ make -j8 test
  $ make -j8 install

Compile sqlite3 (tcl needs to be disabled, otherwise it tries to install things in /usr; tests cannot be done, since they use tcl):

  $ unzip sqlite-src-3220000.zip
  $ mkdir sqlite-src-3220000_build && cd sqlite-src-3220000_build/
  $ ../sqlite-src-3220000/configure --prefix=$HOME/.local/ --disable-tcl
  $ make -j8
  $ make -j8 install

Compile python (tests are already performed during compile time; try adding --with-lto to configure, it should improve things):

  $ tar xf Python-3.6.5.tar.xz && cd Python-3.6.5/
  $ ./configure --prefix=$HOME/.local/ --enable-optimizations
  $ make -j8
  $ make -j8 install

Before doing the make install of python, make sure that it found both ssl and sqlite libraries.
