#2553: Cactus' link command used CPPFLAGS and CXXFLAGS

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

Comment (by Erik Schnetter):

There are some optimizations that recompile code at link time. I don’t think these were ever successfully used in Cactus, nor whether compilers offer them any more. (The current set of `-lto` optimizations might store the compiler flags internally.)

So far, the Cactus policy has been that each stage (preprocessor, compiler, linker) gets passed all the flags of the previous stages.
