Compile Error (GCC 7, implicit-fallthrough) #108

Closed ghost closed 7 years ago

ghost commented 7 years ago

Hi, I get some compile errors with gcc. Maybe disable 'implicit-fallthrough' by default for the build or fix this proper.

gcc (GCC) 7.1.1 20170528 Copyright (C) 2017 Free Software Foundation, Inc.

Thank you for report. I'll install gcc-7 and check it. Meanwhile, you can build libstrophe with make CFLAGS="-DHAVE_SNPRINTF -DHAVE_VSNPRINTF" as workaround.

Should be fixed in master.
