can't find "libpq-fe.h" for postgres on ubuntu18.04

[xuqinghan]

pg in run in docker, so host(a Notebook ) is not install pg, but just install libpg-dev
so libpq-fe.h is exists at /usr/include/postgresql

but luasql install can't find it, even set PGSQL_DIR:

sudo luarocks install luasql-postgres PGSQL_DIR=/usr/include/postgresql

Error: Could not find header file for PGSQL
No file libpq-fe.h in /usr/include/postgresql/include
You may have to install PGSQL in your system and/or pass PGSQL_DIR or PGSQL_INCDIR to the luarocks command.
Example: luarocks install luasql-postgres PGSQL_DIR=/usr/local

add a line ?

Example: luarocks install luasql-postgres PGSQL_INCDIR=/usr/include/postgresql PGSQL_LIBDIR=/usr/lib

Hi xuqinghan The problem you've mentioned is not related to LuaSQL. It is related to the configuration of your docker container. You have to install everything in the container, despite what is installed your host machine. Regards, Tomás Em sex, 12 de abr de 2019 às 22:22, xuqinghan <[email protected]> escreveu:
