Compilation failure on Ubuntu 18.04

[michaelmior]

I get the following issue when running configure on Ubuntu 18.04. Any assistance appreciated :)

$ autoreconf -i

configure.ac:4: installing './missing'

I was able to fix configure by adding ax_boost_base.m4, ax_boost_regex.m4 ,ax_cxx_compile_stdcxx_11.m4, and ax_cxx_compile_stdcxx.m4 to the m4 directory and adding ACLOCAL_AMFLAGS = ${ACLOCAL_FLAGS} -I m4 to Makefile.am. Then when running make I get the following:

make  all-am

Fwiw, the Debian package Build-Depends on autoconf-archive:

Build-Depends: autoconf, autoconf-archive, debhelper (>= 9), libboost-regex-dev, libpq-dev, libpqxx-dev

Thanks! Installing autoconf-archive did solve the majority of my problems. Now I have the following:

checking for libpq-fe.h... yes
checking for the PostgreSQL library linking is working... configure: error: in `/home/mmior/apps/sqlsmith':
configure: error: could not find libpq-fe.h header
See `config.log' for more details

Looking in config.log shows

This error is related to this: #18 (comment)

As a temporary workaround, I manually edited the configure script so that this line:
char conninfo="dbname = postgres";
reads like this instead:
char* conninfo="dbname = postgres";

[michaelmior]

@maahl Yeah, that does the trick :) Thanks for the pointer!
