yade.libVersions module¶
The yade.libVersions
module tracks versions of all libraries it was compiled with. Example usage is as follows:
from yade.libVersions import *
if(getVersion('cgal') > (4,9,0)):
…
else:
…
To obtain a list of all libraries use the function libVersions.printAllVersions.
All libraries listed in prerequisites are detected by this module.
Note
If we need a version of some library not listed in prerequisites, then it must also be added to that list.
When adding a new version please have a look at these three files:
py/_libVersions.cpp: detection of versions from
#include
files by C++.py/libVersions.py.in: python module which is constructed by cmake during compilation. All
*.in
files are processed by cmake.cMake/FindMissingVersions.cmake: forced detection of library with undetectable version.
Hint
The safest way to compare versions is to use builtin python tuple comparison e.g. if(cgalVer > (4,9,0) and cgalVer < (5,1,1)):
