configure ignore given PYTHON env var

EricDeveaud commented 4 years ago

Hello while trying to install MUSIC in a virtual env using

I noted that PYTHON value given to configure is not honored.

see

./configure MPI_CXXFLAGS="-g -O3"  MPI_CFLAGS="-I$MPI_ROOT/include -pthread" MPI_LDFLAGS="-pthread -Wl,--enable-new-dtags -L$MPI_ROOT/lib -lmpi_cxx -lmpi" PYTHON=/opt/gensoft/exe/MUSIC/1.1.16/venv/bin/python

and

[gensoft@38a8dee6f6d5 MUSIC-1.1.16]$ grep '^PYTHON =' Makefile
PYTHON = /opt/gensoft/adm/bin/python

I was expecting PYTHON =/opt/gensoft/exe/MUSIC/1.1.16/venv/bin/python

this makes cd $(PYTHON} tests.py to fail in pymusic/Makefile, more precisely in pyconfig.pxi rule

regards

Eric

Dear Eric,

The way to specify to the configure script that a particular Python version should be used is using the option --with-python:

./configure --with-python=/my/bin/python

What probably happened in your case is that since this option was not given, it looked for a Python in your path.

I've updated README, mentioning this option, in commit b6a8787.

Please tell me if this helps.
