Compile class openwrt when sdk, a gdate.c error occurs, the version of the compiler, make a patch like
problem:
gdate.c: In function 'g_date_strftime':
gdate.c:2497:7: error: format not a string literal, format string not checked [-Werror=format-nonliteral]
tmplen = strftime (tmpbuf, tmpbufsize, locale_format, &tm);
^~~~~~
cc1: some warnings being treated as errors
make[10]: *** [Makefile:1386: libglib_2_0_la-gdate.lo] Error 1
make[10]: Leaving directory '/opt/water/tina-sdk/out/mandolin-perf1/compile_dir/host/pkg-config-0.29/glib/glib'
solve:
Not a single way to change the source code, recompile the next time there may have to change again, so a new patch once and for all
