configure: error: C compiler cannot create executa

ENTERING MY PROBLEM (they can skip it) Hello, I am trying to compile apk application, but I always have many problems due to lack of libraries and applications that my system does not bring and that are not mentioned in the buildozer and kivy requirements. I am stuck in this error after installing a lot of libraries to solve the previous ones. If you have the definitive guide of requirements to work with buildozer and kivy please add it as a complement to this answer. If you think it is better to format the system and start again to install only what is necessary, I am willing, as long as the information you give me is different from what is available in the official pages.

PROBLEM I have: Ubuntu 18.04.1 LTS, Python 2.7.15rc1, Kivy v1.11.0.dev0, Buildozer 0.35 Libraries imported in the .py: kivy, uuid, sqlite3

#    -----------------------------------------------------------------------------
#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
