On my computer, the version of autoconf is 2.59 and automake is 1.9
I build with autogen.sh & configure & make and failed.
I find In Makefile.am:
include/event2/event-config.h: config.h make-event-config.sed
$(AM_V_GEN)test -d include/event2 || $(MKDIR_P) include/event2
$(AM_V_at)$(SED) -f $(srcdir)/make-event-config.sed < config.h > $@T
$(AM_V_at)mv -f $@T $@
There are three undefined variables: MKDIR_P, AM_V_GEN and AM_V_at.
Then I tried:
- autoconf-2.60 / automake-1.10
- autoconf-2.61 / automake-1.11
- autoconf-2.62 / automake-1.11.2
And only autoconf-2.62 & automake-1.11.2 is ok.
Therefore, I recommend changing the autoconf version from 2.59 to 2.62
and automake version from 1.9 to 1.11.2.
Plus autoconf 2.59 is too old - 2003.12.16 [1], so as automake 1.9 -
2004.08.11 [2], while $(AM_V_GEN)/$(AM_V_at) had been introduced in
371a1237 back in 2012.
