Bug#933848: FTBFS if cmake is installed or if built twice in a row

[Joachim Reichel]

Source: pygalmesh
Version: 0.3.6-1
Severity: serious

1) pygalmesh FTBFS if cmake is installed. Actually the build succeeds, but the
resulting binary package is almost empty.

With cmake installed:

 fakeroot debian/rules clean
dh clean --with python3 --buildsystem=pybuild
   dh_auto_clean -O--buildsystem=pybuild
I: pybuild base:217: dh_auto_clean --buildsystem=cmake
   dh_autoreconf_clean -O--buildsystem=pybuild
   dh_clean -O--buildsystem=pybuild
[...]
 fakeroot debian/rules binary
dh binary --with python3 --buildsystem=pybuild
   dh_testroot -O--buildsystem=pybuild
   dh_prep -O--buildsystem=pybuild
   dh_auto_install -O--buildsystem=pybuild
I: pybuild base:217: dh_auto_install --buildsystem=cmake --builddirectory="/mnt/debian/packages/pygalmesh/pygalmesh-0.3.6/.pybuild/cpython3_3.7_pygalmesh/build" --destdir="/mnt/debian/packages/pygalmesh/pygalmesh-0.3.6/debian/python3-pygalmesh" -- 
   dh_installdocs -O--buildsystem=pybuild

Without cmake installed:

 fakeroot debian/rules clean
dh clean --with python3 --buildsystem=pybuild
   dh_auto_clean -O--buildsystem=pybuild
I: pybuild base:217: python3.7 setup.py clean 
running clean
removing '/build/pygalmesh-0.3.6/.pybuild/cpython3_3.7_pygalmesh/build' (and everything under it)
'build/bdist.linux-amd64' does not exist -- can't clean it
'build/scripts-3.7' does not exist -- can't clean it
[...]
 fakeroot debian/rules binary
dh binary --with python3 --buildsystem=pybuild
   dh_testroot -O--buildsystem=pybuild
   dh_prep -O--buildsystem=pybuild
   dh_auto_install -O--buildsystem=pybuild
I: pybuild base:217: /usr/bin/python3 setup.py install --root /build/pygalmesh-0.3.6/debian/python3-pygalmesh 
running install
[... many more lines following ...]
   dh_installdocs -O--buildsystem=pybuild

I don't understand why the bare existence of cmake causes the build process to
behave differently. At least, the package should declare a Build-Conflicts: on
cmake.


2) pygalmesh FTBFS when built twice in a row. This can be fixed by putting

pygalmesh-from-inr.1
pygalmesh-volume-from-surface.1

in debian/clean.
