Unable to build the gem for Ubuntu

[Alexander Teut]

I'm trying to install sqlite3 gem in my RoR project on Ubuntu 20.04 LTS, gcc 9.3.0

gem install sqlite3 passes ok. But when I do bundle install, it fails to compile the projects. The output is following:

make: *** [Makefile:245: sqlite3.o] Error 1

make failed, exit code 2

Why doesn't it compile? I didn't use any special directories or different configuration, all install and config is from default command lines from help.
