Re: [HelenOS-devel] Applications for HelenOS?

Hi,

"On the other hand, if you want to write an application that doesn't
strictly require HelenOS-specific features to work, it would be
preferrable to write an application designed portably, with an
abstraction layer for things that differ between systems. This is my
personal opinion, but I consider unnecessarily platform-locked
applications to be a nonsensical burden. An application that can run
on other systems in addition to HelenOS would be much easier to
maintain and debug than one designed specifically for HelenOS only."
An example of such a portable application that has a HelenOS port and is 
developed out of tree would be GZX (https://bitbucket.org/jiri_svoboda/gzx/)
although the HelenOS port is a bit experimental at the moment. It uses XCW
(cross compiler wrapper tool in tools/xcw) for cross compilation support.

I'll be improving this are in coming months. If you have issues, or
there are missing POSIX library functions you need, I'm currently the
best person to ask for help. Feel free to send me a message, and you
can also find me on our IRC channel, under the name "jzr". :)

GitHub is the gold standard right about now.
You can publish whatever you are working on in your own personal
repos, and inform the community about it via this mailing list.

Dear Germain,

thanks for your interest in HelenOS! Please see my comments below.

Currently one has to create a directory in uspace/app/ and provide a
corresponding Makefile along with the application itself. The new
application's dir needs to be mentioned in uspace/Makefile so that it is
built by the build system and in boot/Makefile.common so that it is part
of the boot image.

The repo of interest is:

https://github.com/HelenOS/helenos

Another option is to provide a harbour for a ported application. See below.

One creates a new harbour in:

https://github.com/HelenOS/harbours

Note that it might not be very straightforward to port an application as
our support for POSIX APIs is quite limited.

There is a document:

When you have something to submit, please create a GitHub PR either:

or:

HTH,
