Today decided to upgrade FS, after almost 5 months from last upgrade, and executed 'make current' However, it failed with the following errors: ... create mode 100644 src/mod/event_handlers/mod_cdr_mongodb/mod_cdr_mongodb.c delete mode 100644 src/mod/timers/.empty create mode 100644 swig_common.i make[1]: Leaving directory `/usr/local/src/freeswitch' make all make[1]: Entering directory `/usr/local/src/freeswitch' cd . && /bin/sh /usr/local/src/freeswitch/build/config/missing --run aclocal-1.9 cd . && /bin/sh /usr/local/src/freeswitch/build/config/missing --run automake-1.9 --gnu *configure.in:27: required file `build/config/config.sub' not found* make[1]: *** [Makefile.in] Error 1 make[1]: Leaving directory `/usr/local/src/freeswitch' make: *** [current] Error 2 Could you please hint what has changed since then or what I am doing wrong? Thank you, Vitalie
