Hallo Archlinux now uses libpng15. This version is not API-compatible with libpng14 which I have used on my last build. As i am using pywebkitgtk as engine for pyjamas desktop i have errors.
In short pyjams desktop doesn't work anymore on my Arch box. Now i try to rebuild pythonwebkit..... As Arch has updated perl to version 5.14 i had to do some patches in the *.pl files (Switch module is deprecated). This was easy to do. In addition I have patched PNGImageDecoder.cpp (as of linpng15). Here in detail what i have done: ---------------------------------------------------------------------- git clone git://git.savannah.gnu.org/pythonwebkit.git cd pythonwebkit git checkout python_codegen As of perl 5.12 the Switch module is deprecated. The following modules must be adjusted: WebKit/scripts/generate-webkitversion.pl -> Imported but not used, just remove `use Switch;` at line 39 WebCore/dom/make_py_names.pl -> Replace `switch-case` statements with `given-when` statements (replace `else-case` with `default-case` as well) WebCore/dom/make_names.pl -> Imported but not used, just remove `use Switch;` at line 38 WebCore/make-hash-tools.pl -> Replace `switch-case` statements with `given-when` statements See http://pyjs.org/wiki/pyjamasubuntuwebkitgtk/#index4h2 Currently there is a bug with pythonwebkit code and gcc 4.6.1 so you need to edit the file `JavaScriptCore/wtf/ByteArray.cpp` and add `#include <cstddef>` at line 29 With libpng15 the file WebCore/platform/image-decoders/png/PNGImageDecoder.cpp must be adjusted. A patch is avaiable here http://sourceforge.net/mailarchive/forum.php?thread_name=AANLkTikh8Aeq2ogX_fEG3MsoJEundn0Fhti8m5cvpUjE%40mail.gmail.com&forum_name=png-mng-implement I don't know if one can apply the patch directly (i have done the changes by hand). On Arch-Linux /usr/bin/python points to python3. Change this before build.
