#2553: Cactus' link command uses CPPFLAGS and CXXFLAGS

Reporter: Roland Haas Status: open Milestone: Version: development version Type: bug Priority: minor Component: Cactus

Comment (by Roland Haas):

This changes the way option lists behave, so should be reconsidered only after the May 2022 release since it requires use of `LD_XXX_FLAGS` to set settings that were previously inherited from `CPPFLAGS` and `CXXFLAGS` on the linker line.

The branch also has the unrelated commit [https://bitbucket.org/cactuscode/cactus/commits/f04408489af6800ad8d5e177eabd...) which is not strictly related to the subject of the ticket and instead disallows multiple definitions with pgCC by defatul in the same manner that gcc starting with version 10 does (`-fno-common` is the default in gcc10 and up).
