Problems building VisIt on Debian 10.

[brugger1]

Greeting VisIt Developers,

I'm trying to compile VisIt 3.1.1 on a machine running stock Debian 10
(stable) using:

/build_visit --parallel --fortran --uintah --no-icet --mesagl --openssl --llvm --system-cmake --no-visit --console --makeflags -j20

On the first attempt I ran into an error compiling python:

• info 'Installing pyparsing ...'
• [[ yes == \y\e\s ]]
• echo 'Installing pyparsing ...'
• [[ build_visit_log != /\d\e\v/\t\t\y ]] log 'Installing pyparsing
• ...'
• echo 'Installing pyparsing ...'

/usr/installed/VisIt/3.1.1/thirdparty/third_party/python/3.7.5/linux-x86_64_gcc-8.3/bin/python3
./setup.py install
--prefix=/usr/installed/VisIt/3.1.1/thirdparty/third_party/python/3.7.5/linux-x86_64_gcc-8.3

from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'

The solution was to install the libffi-dev package, as discussed at:

sudo apt-get install libffi-dev

On the second attempt I hit:

The build_visit_log is attached.

I'll try using the system's qt5 libraries. I'll verify that all the libraries are installed by comparing the system's libs against what is provided in:

visit3_1_1.linux-x86_64/3.1.1/linux-x86_64/lib

Thanks,

Those errors are handled by the patch function "apply_qt_5101_centos8_patch" in build_visit. It only gets applied with centos 8 and ubuntu 19. It looks like it need to get applied on debian 10 as well. You can search build_visit for "apply_qt_5101_centos8_patch" and move it outside of the tests that determine if it is centos 8 or ubuntu 19.

I am submitting a ticket to also apply the patch for debian 10, with a target of 3.1.2.

I submitted ticket #4638 to fix build_visit for debian 10.
