To build up my portfolio I'm writing an application to showcase all the best practices I'm aware of, including unit tests and continuous integration.
The project was originally started in C++, and I took advantage of buddy.works to compile it and run my tests there. Managing
CMakeLists was a pain but I endured for the greater good.
After a while I noticed that Qt would have been a better fit for my purposes. Being this a non-commercial open source project I'm allowed to use Qt Creator for free. However, buddy.works (and almost all other free CI tools) only allow bare
GCC build environments. In my case I'd need a fully configured Qt environment, as when I install the IDE, plus Android SDK and NDK.
I see buddy.works allows to run commands in a "private container", but I'm not sure if building a container myself (something I'd start looking into if I knew this would work).
I guess the safest choice would be to rent an Amazon EC2 instance, install on that everything I need (Qt, SDKs, Jenkins) and configure it to communicate with my GitHub or Bitbucket, but it would cost me (and I can't say how much exactly). I expect the CI process to only run like thrice per week, with an average build time that at most would take half an hour. I also liked the idea of the green build badge in the readme file, something buddy.works offered and with an EC2 instance shutting down could be trickier to achieve (if I was to purchase an instance that boots every day, runs CI and shuts down). However, a free alternative would be much appreciated.
Any hint about this? Thank you very much.
