CppCMS Going Embedded... or I need your help!

2/15/09, by artyom ; Posted in: Progress, Framework; 2 comments

Recently I start understanding that embedded market may be very important market for CppCMS. So I did several tweaks to the code in order to support embedded systems:

  1. When the library is compiled for embedded system, caching system is totally removed, removed dependency on boost::iostreams and compression library.
  2. Mod-prefork is removed as much more memory consuming.
  3. Removed dynamic loading of templates.
  4. Option for cgi-only library given --- no scgi and and fastcgi APIs are compiled in, all remaining worker "mods" are removed.
  5. Session storage backend is simplified and optimized for cgi when it is compiled in embedded mode.

Everything was cross compiled for arm and tested with qemu-arm, but unfortunately I do not have an access to real ARM hardware with installed Linux system, so...

I need your help:

  1. Download following test_arm_embed.tar.gz
  2. Copy it to your ARM system and extract files.

  3. Try to run cgi script from command line:

     ./hello.dynamic -c config.txt

    This is "Hello World" that is dynamically linked with libstdc++. If it does not work try

     ./hello.static -c config.txt

    This is full statically compiled version of "Hello World" cgi script.

    You should get as output CGI headers and HTML output.

  4. Please, try to run it several times with:

     time ./hello.dynamic -c config.txt

    And tell the average run time.

  5. If you have a web server in your system I'd be very glad if you could test cgi script -- please edit it --- test.cgi to reflect correct executable and path.

I all works fine I'd be glad (if it is possible) to prepare a set of scripts that would test various aspects of cppcms as templates, various session backends and so on.

Thanks

Hello . I just found your site now while looking for a web development framework for c++.

I think this is a great idea and I certainly think it has a lot of potential. I think it's especially useful for embedded sutff.
I have a router for instance and it's got Linux + a lousy asp stuff web based GUI.

It's slow as hell and not that useful.
Having said that I still didn't manage to hack my router so I can get console access and run stuff on it.

As soon as I do however I will help as I can and provide you with some results. I'm just learning c++ but if I can I hope to help with the development soon. Keep on the good work you're doing here. I for one think it has a lot of potential.

Hello Marius,

Having said that I still didn’t manage to hack my router so I can get console access and run stuff on it.

I would suggest you start working in normal environment and then cross compile to embedded.

This would give you an experience with this framework before you are going deep into embedded.
