# Building SageMath 9.1.rc3 on Debian 9
Based on a working Sage 9.1.rc2.
## Configure
```
$ git pull origin develop --tags
[...]
$ make configure
[...]
$ ./configure
[...]
```
The `./configure` step recommends:
```
$ sudo apt-get update
$ sudo apt-get install libboost-dev coinor-cbc coinor-libcbc-dev
pari-gp2c libisl-dev libxml-libxslt-perl libxml-writer-perl
libxml2-dev libperl-dev libfile-slurp-perl libjson-perl libsvg-perl
libterm-readkey-perl libterm-readline-gnu-perl libmongodb-perl
```
But some of them are already there:
```
$ dpkg-query --list libboost-dev coinor-cbc coinor-libcbc-dev
pari-gp2c libisl-dev libxml-libxslt-perl libxml-writer-perl
libxml2-dev libperl-dev libfile-slurp-perl libjson-perl libsvg-perl
libterm-readkey-perl libterm-readline-gnu-perl libmongodb-perl

This might be (?) in the same vein as the problem reported at
- Sage Trac ticket 29586
Improve configure recommendations

## Build
```
$ make -s V=0
[...]
```
All fine.
## Tests
I wonder if it's normal that `make ptestlong` seems to
start by `make sagelib` and `make dochtml` even though
those were run just before. I forget if there's a ticket for that.
Two files with failing doctests:
```
$ make ptestlong
[...]
--
sage -t --long src/sage/tests/cmdline.py # 3 doctests failed
sage -t --long src/sage/interfaces/psage.py # 1 doctest failed
--
Total time for all tests: 1669.1 seconds
cpu time: 11902.3 seconds
cumulative wall time: 12716.7 seconds
Makefile:182: recipe for target 'ptestlong' failed
make: *** [ptestlong] Error 1
$
```
## Retest the files with failing doctests,
One of them(`src/sage/tests/cmdline.py`) still fails 3 doctests:
```
$ ./sage -t --long src/sage/tests/cmdline.py
too many failed tests, not using stored timings
