Connect RetDec to a continuous integration service supporting FreeBSD

[s3rvac]

At present, RetDec can be built on Windows, Linux, macOS, and (experimentally) on FreeBSD (#476). However, we have continuous integration only for Windows, Linux, and macOS. As suggested here, it would be a good idea to also connect RetDec to a continuous integration service supporting FreeBSD, such as https://cirrus-ci.com/.

As we have no experience with FreeBSD, we encourage the community to help. For inspiration, you can take a look at .appveyor.yml and .travis.yml.

Great! Also the FreeBSD community have what is called a ports collection, with over 26,000 ports being maintained by individuals and teams. The ports collection is compiled into packages which rather than building the port yourself, you can download and install a pre-built package.
There are many massive organisations that use FreeBSD as servers or in embeded systems and contribute including Apple (as the OSX & iOS are based on FreeBSD). Netflix, Cisco, Whatsapp ($1m donation every year), EMC, Sony, VMWare, Yahoo.. etc.
If you want to know more about a particular company go to youtube.com and search for example "netflix freebsd".
FreeBSD is exceptionally stable including all its ports and packages. Everything works first time every time! Updating to the latest FreeBSD operating system is as easy as freebsd-update -r <release>

I am sure there will be people interested to help. :)

PCBSD is probably the best place to start. As it will give you a nice GUI Desktop, where as FreeBSD (out of the box) will give you a basic server and you have to install all the packages to get a GUI Desktop.
(Another lifetime ago started on Linux/GNU but switched!)

Hey @gwquk , since you ported RetDec to FreeBSD, do you want to help connect this project to Cirrus CI? Here is a simple example and hope it helps: https://github.com/facebook/zstd/blob/dev/.cirrus.yml

If you would also like to create a port, it will be even better and I'll do anything I can help!

[gwquk]

I'll give it a go, more than happy to help with both. Not done it before but I am sure you and google can help. 👍

OK, If I understand what is going on below.

1. For FreeBSD 12-0 & 11-2 releases on the amd64 architecture.
2. Change the (searched) text in /etc/pkg/FreeBSD.conf backing up the original to /etc/pkg/FreeBSD.conf.bak
   from "pkg+http://pkg.FreeBSD.org/${ABI}/latest" to "pkg+http://pkg.FreeBSD.org/${ABI}/latest"
3. Upgrade all currently installed "Packages" to the latest package.
4. Install all the packages needed by "retdec". (if already installed FreeBSD will say they are up to date)
5. And finally ... the script needed to build "retdec"... including any environment variables to set.
   Note: That is as far as it goes... i.e. "retdec" is not installed by the look of things (just built)! Also.. A freshly installed version of FreeBSD may require more packages installed.

Iwshu, Is this what you are looking for?

@gwquk yes this one looks nice to me, except that I think we need one more 'N' argument after make -j. Also, may I suggest you test this .cirrus.yml in your fork repository with cirrus-ci?

[gwquk]

OK! I'll give it a go.

I have not submitted a port before, I'll make a few files.
I suspect "retdec" would go here "/usr/ports/devel/retdec" in the "ports tree"
I suspect these standard files will be needed..
Makefile distinfo pkg-descr pkg-message

[lwhsu]

All of these sound reasonable to me. I would also recommend you reading the porter's handbook: https://www.freebsd.org/doc/en/books/porters-handbook/ and discuss on freebsd-ports list if you have further question: https://lists.freebsd.org/mailman/listinfo/freebsd-ports

[gwquk]

Great! As I did not introduce myself.. I have been using FreeBSD activitely since around version 2.2.7 .. I did have a version 1.0 CD not sure where that went! Although I changed careers back in 2007, I have always maintained a few FreeBSD boxes. What about yourself?

[lwhsu]

My FreeBSD history is shorter than you :) you can find my public information on my github page.
