* Initial creation of os_compat.h.Fred Wright2017-01-221-3/+1
| | | | | | | | | | | | | | | | | This creates a header for os_compat.c, and moves the related prototypes into it from gpsd_config.h (as created by SConstruct), after adding references to it to gpsd.h (via gpsd.h-tail) and a few other sources that need it but don't include gpsd.h. It also removes includes of <time.h> in the places where they were only needed for the code now removed from gpsd_config.h. TESTED: Ran "scons build-all check" on OSX 10.9 (with strlcat/strlcpy but no clock_gettime), OSX 10.12 (with strlcat/strlcpy and clock_gettime), and Ubuntu 14 (with clock_gettime but no strlcat/strlcpy). Also verified that fallback versions were not being included where unnecessary.
* Cleans up some ordering in os_compat.c.Fred Wright2017-01-221-11/+16
| | | | | | | | | | | | | | | | | | | This rearranges the order of some conditionals and includes, in order to avoid some gratuitous includes where unnecessary. Due to the fact that some actual definitions for the clock_gettime fallback are embedded directly in gpsd_config.h, it's necessary to include <time.h> prior to including it. This will be fixed once the relevant definitions are moved to the upcoming os_compat.h. This also replaces the "UNUSED" in clock_gettime with a void cast, eliminating the need for compiler.h. TESTED: Ran "scons build-all check" on OSX 10.9, OSX 10.12 (which has real clock_gettime) and Ubuntu 14. Also verified that the clock_gettime fallback is present in OSX 10.9, but absent in OSX 10.12 and in Ubuntu 14.
* Initial edit and use of new os_compat.c.Fred Wright2017-01-221-9/+23
| | | | | | | | | | | | | | This change: 1) Makes a few comment-only edits to os_compat.c. 2) Updates the build procedure to use os_compat.c in libgps and in the Python extensions. 3) Deletes the now-obsolete clock_gettime.c, daemon.c, and strl.c. TESTED: Ran "scons build-all check" on OSX 10.9 and Ubuntu 14.
* Initial checkin of new os_compat.c source.Fred Wright2017-01-221-0/+230
This file combines the code from clock_gettime.c, daemon.c, and strl.c into a single "OS compatibility" module. This initial version is just a verbatim concatenation of those three sources, which is not yet used. Editing it for initial use is left to a separate commit for easier tracking of the edits. Since there's no "git cat" operation, the history of the code in this file is not directly available in relation to this file, but can be found in the histories of its three component sources (even after their upcoming deletions). TESTED: Inapplicable.
