falcON does not compile on MacOSX

[jcldc]

I fixed some compilation issues about falcON on macos platform (g++ and clang++), and removed again compilations warning.

The pb was coming from error and warning functions both declared in NEMO and clang/glibc and causing linking failures.

see falcON_compile branch

I have a Catalina (10.15.x) running, but haven't seen any issues with gyrfalcON. Perhaps an older clang version.

Actually gyrfalcON was compiling correctly before the modification, but not the ${NEMO}/usr/dehnen/falcON/src/public/acc manipulators. The reason is because warning and error functions are called from <defacc.h> and if you don't include <stdinc.h> before <defacc.h>, clang give an error message during the link, because warnings and error are also defined in clang library !!!! When you install nemo using install_nemo script, gyrfalcON can be compiled but not these acc manipulators, at least from my macosx Sierra version. Could you check that you have *.so files in ${NEMO}/usr/dehnen/falcON/acc, like this :

sounds like I need to add a regression test for this.

ugh, fish memory, the "make check" will do all the acc/manip tests of the dehnen code under "src/nbody/evolve/dehnen" entry.

[teuben]

Indeed,my Catalina does not have them. They are formally copied in $NEMOOBJ/acc, which is also non-existent on my mac.
