pthreads for wince

[patrick.east]

Good news.

I've gotten the go-ahead to push our pthreads to a webkit-thirdparty
clone. We have gotten it to work with the latest webkit source code,
and it seems to work just fine for us on CE6 and CE7.

The pthreads library depends on another library we put into our webkit-
thirdparty repo called wceshunt. We were unable to get pthreads to
compile without it so make sure you use both.

I've gotten cmake files for the libraries added in, they work for our
webkit builds...We have deviated a bit from the mainline wince code,
so I make no guarantees that they will just build on the latest tree
without a little help.

Let me know if you guys have any questions or problems with them.

I guess the location of the repo would help ; )

Hi Patrick

 

Firstly thanks for doing this - I'd been looking at this myself :)

 

Can I build this outside of the WebKit build?  We need to use the SVN trunk rather than the CE specific git repository but I get CMake errors when I try to generate the makefiles.  I'm using the CMake I built using the instructions on the Wiki (http://trac.webkit.org/wiki/WinCE) and the following command line:

 

cmake -G "Visual Studio 8 2005" -DCMAKE_WINCE_SDK="STANDARDSDK_500 (ARMV4I)" -DPORT=WinCE \path\to\git\clone\of\bsquare-webkit-thirdparty

 

Which gives me the following error:

 

CMake Error at icu/CMakeLists.txt:539 (ADD_TARGET_PROPERTIES):
Unknown CMake command "ADD_TARGET_PROPERTIES".

 

Thanks,

 

Phil

It is possible to build it outside of the webkit build, but you would have to modify the project files.

I'm not sure why you get that error, that macro should be defined in Source/cmake/WebKitHelpers.cmake

This error is also in the icu library we added, I don't think you would need it for the svn wince build, you could just comment out the "ADD_SUBDIRECTORY(icu)" line in the CMakeLists.txt for the thirdparty directory.

I don't want to sound negative about a code contribution/donation, but I was wondering why it is 

that we want to have a pthread dependency in the first place for WinCE?

Thanks,

We don't want to have the dependency.

Patrick Gansterer has pushed to remove the dependency (and I'm sure can explain more about what happened with it), but I havn't seen any change on his patch to remove it... It appears the rest of the webkit community wants to keep the threading as it is. 

This is only meant to unblock the wince port from moving forward and staying up to date with the rest of webkit, not as a permanent solution.

If you're interessted in this issue: Please follow https://bugs.webkit.org/show_bug.cgi?id=68429

Current state: I still want to get rid of the dependency, but need some WebKit folks to find a solution, which needs the WebKit coding requirements. In the meantime the Qt folks checked that their Windows port depends on pthread too, which IMHO a blocker for a next release. I had a longer discussion with Simon on IRC about this topic. but have not found a clean solution yet.

So: If you want to compile without pthread: Use the patch at the bug. It should apply and work.

And: If you have plenty of time: Create a patch, which meets all WebKit requirements, and post it at the bug.
