Compilation errors #78

Closed dtheodor closed 7 years ago

dtheodor commented 7 years ago

Trying to compile on CentOS Linux release 7.3.1611 (Core) with postgres 9.6.2

When running ./autogen.sh --with-legacy I'm running into a json-c compilation error caused by this issue https://github.com/json-c/json-c/issues/159.

I updated json-c to 0.12.1 which fixes it. Now, when running PATH=/usr/pgsql-9.6/bin/:$PATH make I'm running into

clean your build, recompile after export CPPFLAGS=-fPIC and it should work fine.

dtheodor commented 7 years ago

yea, after a make clean it worked

Should we add the full compilation/install instructions in the main readme, I found them only by searching in the repo issues and in readmes of past versions. Something like:

Make sure pg_config is in your PATH, and you are running as root

./autogen.sh --with-legacy
make
make install

Why not, could you please open a new issue to track that readme change.
