It is defined in uClibc's features.h. You should never be manually defining this macro. Instead, your application source or Makefile should be defining the appropriate feature macros as described in the feature_test_macros man page, and features.h will then define the above based on those features. > Would that say that I have to define it explicitly by changing uClinux > Makefile and passing the defines to copiler line options ? No. uClibc always includes the usleep function definition, no defines are needed for that. The only defines needed are in your application before it includes the header files, in order to control visibility of the usleep function prototype. > Similar when I compile apps, I always have to explicitly add -D_XOPEN_SOURCE ? That is the correct way to do it (or #define _XOPEN_SOURCE at the top of your application source file). _______________________________________________ uClibc mailing list [email protected] http://lists.busybox.net/mailman/listinfo/uclibc
