Error when running ./configure on Ubuntu 20.04

[raphahardt]

I'm having trouble trying to install Mapnik v3.0.23, downloaded from the releases.
I'm following the instructions for installing from here: https://github.com/mapnik/mapnik/wiki/UbuntuInstallation

My OS is Ubuntu 20.04. Harfbuzz was installed and compiled beforehand (2.7.2)
It is worth noticing that the installation is expecting the "freetype-config", which in Ubuntu 20 is not supported anymore in favor of "pkg-config"

I tried change de FREETYPE_CONFIG variable, but no success.

Log:

Exiting... the following required dependencies were not found:
   - freetype-config (freetype-config program | try setting FREETYPE_CONFIG SCons option or configure with FREETYPE_LIBS & FREETYPE_INCLUDES)
   - harfbuzz-with-freetype-support

See '/home/teste/Downloads/mapnik-3.0.23-do-site/mapnik-3.0.23/config.log' for details on possible problems.

Also, these OPTIONAL dependencies were not found:
   - proj (Proj.4 C Projections library | configure with PROJ_LIBS & PROJ_INCLUDES | more info: http://trac.osgeo.org/proj/)

Set custom paths to these libraries and header files on the command-line or in a file called 'config.py'
    ie. $ python scons/scons.py BOOST_INCLUDES=/usr/local/include BOOST_LIBS=/usr/local/lib

Once all required dependencies are found a local 'config.py' will be saved and then install:
    $ sudo python scons/scons.py install

To view available path variables:
    $ python scons/scons.py --help or -h

To view overall SCons help options:
    $ python scons/scons.py --help-options or -H

@raphahardt - do you have freetype-config on your system ? If not, you can't use FREETYPE_CONFIG route, try setting FREETYPE_INCLUDES and FREETYPE_LIBS as suggested in your stderr :

freetype-config (freetype-config program | try setting FREETYPE_CONFIG SCons option or configure with FREETYPE_LIBS & FREETYPE_INCLUDES)

@raphahardt

#3870
#4164 <-- has a pointer to a workable solution e.g

Missing freetype-config:
''freetype-config'' is depreciated and ''pkg-config'' should be used instead. A fix for this is available and was merged with master in #3892, but SConstruct in v3.0.23 doesn't include them. Adding those checks resolves the freetype-config dependency.

Thank you very much! I didn't see that the same issue was opened before, I'm sorry.
The solution of define FREETYPE_LIBS and FREETYPE_INCLUDES worked on the configure phase, but now on the "make" phase I got this (see below):

Seems like some file is missing. I downloaded the zip from the releases page, so I assume it has all the files needed.
I can try cloning from the repo and clone the submodules if that is the case.

Thanks in advance

@raphahardt - yes, you need to run git submodule update --init after cloning

[raphahardt]

It worked. Thank you!
