0000087: Compiler error for GCC 4.7: src/protocols/jd2/SingleFileBuffer.cc:148:13: error: 'sleep' was not declared in this scope

Notes
(0000084) smlewis (Administrator) 2012-08-27 09:57	#include <unistd.h> allows compilation in this case. I have not changed anything in SVN and am not marking this as fixed until/unless someone with GCC 4.7 can test out possibly-more-appropriate headers.

(0000107) honda (Developer) 2012-09-20 11:53	How about providing a home-made sleep() using the standard C library's nanosleep()? #include <time.h> // sleep for secs seconds. return 0 if completes without interruption. int sleep(int secs) { // time to sleep struct timespec req; req.tv_sec = secs; req.tv_nsec = 0; // remaining time in ns will be saved here if interrupted. // nothing will be saved when NULL. struct timespec * rem = NULL; // return 0 if successful. non-zero otherwise return nanosleep( &req, rem ); }

(0000108) smlewis (Administrator) 2012-09-20 14:32	I spoke briefly with Andrew, who agrees that "#include <unistd.h>" is not a viable solution. The bigger question is, what sleep() does SingleFileBuffer think it is calling, is it calling that function in all versions/compilers or is it accidentally miscompiling, and finally why does 4.7 treat it differently than other version? I guess a locally-defined sleep() is a functional solution, but it implies that there really isn't a portable, STL-defined function that does that, which seems strange...
