#3257: Do not require ctypes for compilation in temporal modules
-------------------------------------------------+-------------------------
Reporter: wenzeslaus | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.2.1
Component: Temporal | Version: unspecified
Keywords: ctypes, compilation, build, | CPU: Unspecified
homebrew, brew, conda, macos, osx, |
v.what.strds, t.create |
Platform: All |
-------------------------------------------------+-------------------------
The temporal modules require ctypes even during compilation. This makes
the whole compilation more fragile. When ctypes fails compilation fails.
This currently happens for example with Homebrew on Mac or in Conda
environment (see below examples of error messages). The errors are
somewhere else and the modules won't work, but I think the failure should
come only when user actually needs them. The temporal modules should not
break the build with ctypes not present or the dynamic libraries broken.
The list of directories with errors:
{{{
/usr/local/src/grass/scripts/v.what.strds
/usr/local/src/grass/temporal/t.create
/usr/local/src/grass/temporal/t.support
...
/usr/local/src/grass/temporal/t.vect.what.strds
/usr/local/src/grass/temporal/t.vect.observe.strds
/usr/local/src/grass/temporal/t.vect.univar
}}}
Examples of actual errors:
