Re: Problem building psql on Mac OS 10.15 (around readline bit I think)

Hi Tom,

thanks for such a quick reply - there's the rub, I really can't think of
anything other than apple point updates.

I checked the configure output, and it noted that neither of those
functions were available (but didn't appear to change anything or not try
building)

I then installed readline-8.1, and added:

./configure --prefix=/usr/local/pgsql-${PG_VERSION}
--with-extra-version=-bm \
--with-bonjour --with-uuid=e2fs \
--with-libxml --with-libxslt \
--with-python
PYTHON=/Library/Frameworks/Python.framework/Versions/3.9/bin/python3 \
--with-system-tzdata=/usr/share/zoneinfo \
--with-openssl \
--with-libraries=/usr/local/ssl/lib:/usr/local/lib \
--with-includes=/usr/local/ssl/include:/usr/local/include/readline

to the configure, and the configure output now showed both available,

checking for rl_reset_screen_size... yes
checking for append_history... yes

and it shows

configure: using CPPFLAGS=-isysroot $(PG_SYSROOT)
-I/usr/local/include/libxml2 -I/usr/local/ssl/include
-I/usr/local/include/readline
configure: using LDFLAGS=-isysroot $(PG_SYSROOT) -L/usr/local/lib
-L/usr/local/ssl/lib -Wl,-dead_strip_dylibs

at the bottom of the configure output but the build script still failed at
the same point showing the same error citing the readline/history.h from
the apple SDK's... is there something else I have to do to ensure it uses
the ones on the PATH and specified in the configure?

cheers

Ben
