The installation procedure for the impatient and/or experts:
0) create configure in the source directory:
$ ./autogen.sh
1) create a directory for object files (you cannot build in the source directory):
$ mkdir ../build; cd ../build
2) configure the package:
$ ../src_dir/configure
Most often you will need to specify command-line options to configure.
To obtain a list of configure options run 'configure --help'.
then either choose path a or b:
3a) build the Libint compiler, then generate and compile a library:
$ make
4a) optional validation of the library:
$ make check
5a) install the compiled library:
$ make install
3b) build the Libint compiler, then generate and package a library for redistribution
$ make export
this produces a tarball with a Libint library that can be unpacked, configured, and compiled elsewhere.
To build Python module configure libint with `--enable-eri2 --enable-eri`, export, untar exported archive:
$ cmake -DPYTHON_EXECUTABLE=`which python3` -DLIBINT2_PYTHON=ON .
$ cd python
$ make && make test
$ make libint2-python-wheel
