Hi Hans, IOhannes
I don't have a clue what MSG_DONTWAIT is. I think I need some help (from IOhannes?) to get this one fixed.
it's a (linux-specific?) extensions for non-blocking socket receivers. the problem should be fixed now (by only using MSG_DONTWAIT if it is available)
Thanks.
Altough I had the same error once on Linux (I didn't do 'make clean'), it doesn't happen in the Linux autobuilds, probably because the pd/src directory is clean at the time of externals build.
Hints/help is appreciated.
hmm, i think the problem is a stupid error-checking condition in gcc, that guarantuess that you only specify "directories" as "include directories". i have never seen this on linux, so it might be an osx specific "feature".
FYI: It happens also on Linux, if you didn't 'make clean' in the pd sources before.
a simple fix would be to remove the '-I"$(PD_INCLUDE)/pd"' stanza. i'm a bit reluctant to commit this, as i would first like to understand why the compiler thinks it an error when specifying an include-directory that is a file (but not, if you specify an include-directory that is non-existant)
I'm afraid I also do not understand why this considered an error. A work-around would be to check if src/pd is a file or a directory and only add '-I"$(PD_INCLUDE)/pd"' if it really is a directory.
The newest library template version handles this much better. I think its something that IOhannes worked out with the PD_INCLUDE var pointing directly to the dir that actually has the headers, and PD_PATH pointing to the root of the Pd tree. The default include statement is now -I$(PD_INCLUDE) so its easily overrideable.
Just for the record: Both errors were not related to iemnet's Makefile being based on an old version of the template.
The OS X error is (hopefully) fixed now, because IOhannes removed '-I"$(PD_INCLUDE)/pd"' from ALL_CFLAGS (which was also not part of the older template version).
The windows error wasn't related to the Makefile at all.
Anyway, it's good it's based on a current template now.
