Alpine build

[padiazg]

Hi, just want to know if anyone already tried to make an Alpine Build.

[padiazg]

Handled to compile in a Docker/Alpine container. Here is my github repo: https://github.com/padiazg/harbour-alpine

There is two files that had to modify, because of dependencies:

• arc4.c: comiler complains about sysctl, after searching a lot found some info and decide to coment line 53. Please somebody tell me if this is correct, or what would be the right approach.

• mysql.c: Alpine lacks mysql packages, so I used MariaDB, but there is a constant named MYSQL_PORT, so I added this to solve it.

  #if !defined(MYSQL_PORT )
  #if defined( MARIADB_PORT )
      #define MYSQL_PORT MARIADB_PORT
  #endif
  #endif

  In the examples folder there are two tests, bmmysql works without a problem, but sddmy that used RDD fails with segmentation fault.

Working on test some other functionalities that are of my interest, postgres and CGI for example.

@alcz No need to test for HB_OS_LINUX - already checked line above. Checking for GBLIC/UCLIBC works as well.

I have just tested that on Alpine. Works.

[alcz]

It is checked above together with HB_OS_BSD. I wouldn't want to change anything for such systems. They are rather non-GNU, but there is also Debian GNU/kFreeBSD.

Still my patch would touch BSD, i've edited it now, after your note. Need to make some build tests on other distros.

@padiazg It might not fix Alpine builds but works. You can use ubuntu images as build environment and then run compiled binary on Alpine (using Docker multi-stage builds).

https://docs.docker.com/develop/develop-images/multistage-build/

Example: https://github.com/felixd/docker-harbour-example/blob/master/restful-34/Dockerfile https://github.com/felixd/docker-harbour-example/blob/master/.travis.yml

Check: https://github.com/felixd/docker-harbour - based right now on ubuntu:latest https://github.com/felixd/docker-harbour-example

I don't know about Alpine builds... but I have Alpine 3.17 installed native (no containers) on one of my laptops and Harbour/Core compiles and installs ok if the required dev libraries are installed. It is also true for GNUCobol...

I have wrote that back in 2019. Things might have change since that time. Thanks for pointing that.
