Re: [platform-swt-dev] How to build SWT JNI Natives on gtk-linux-x86_64 ?

I've worked on porting webkit1 to webkit2.

At the moment webkit1 is notorious for crashing a fair bit. Do you have webkit2 on your system? You could try running eclipse with webkit2 if you have it installed.
pkg: webkitgtk4.x86_64    << webkit2 with gtk3 bindings.


then:
export SWT_WEBKIT2=1
./eclipse

Note, you should be running newest eclipse, e.g nightly/integration build that has latest webkit2 fixes:
http://download.eclipse.org/eclipse/downloads/drops4/I20170417-2000/download.php?dropFile=eclipse-SDK-I20170417-2000-linux-gtk-x86_64.tar.gz

Webkit1/Webkit2 & Fedora/RedHat is one of my main responsibilities, please feel free to reach out to me via IRC for quicker support if you like:

Hi again,

 

So I can answer the 3rd question myself (“hang on printers”), this was

https://bugs.eclipse.org/bugs/show_bug.cgi?id=215234

and I could work around it by “sudo yum install cups && /etc/init.d/cups restart”.

 

Tests are looking reasonably good now, though I encountered a reproducible crash:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=515471

 

And, quite early in the test suite some 50 tests always fail with “not implemented [multiple displays]”.

See attached screenshot – re-running the failed tests only (from the Junit “failed tests” filter) makes

Them succeed. Any ideas on that one?

 

The other 2 questions remain from below E-Mail (regarding docs and how to build properly).

 

Thanks,

Martin

Subject: [platform-swt-dev] How to build SWT JNI Natives on gtk-linux-x86_64 ?

 

Hi SWT Experts,

 

I’m trying to build my own SWT GTK Fragment on RHEL 6 / x86_64

(because of https://bugs.eclipse.org/bugs/show_bug.cgi?id=515155 ).

 

1.      I followed this article, running build.xml:build_libraries from the gtk.linux.x86_64 fragment:
https://www.eclipse.org/swt/jnigen.php
but the build runs into an error:
[exec] cc1plus: error: /bluebird/teamswt/swt-builddir/mozilla/1.7/amd64/mozilla/dist/sdk/include/mozilla-config.h: No such file or directory

    

2.      So I found “Building the SWT natives on Ubuntu…(without XULRunner support)” here:
https://www.eclipse.org/swt/faq.php#howbuilddll
And adding “targets = install” on the Properties tab did help, but I found the instructions inaccurate because they didn’t ask to select build.xml in the org.eclipse.swt.gtk.linux.x86_64 fragment before doing right-click > Run As > Ant Build…

 

3.      So finally I tried running “build.sh” as per the FAQ URL above, since it seemed to be able to find the libxulrunner-dev of my system. But the build.sh resides in a different directory than documented and running it produces this error:
make_linux.mak:23: make_common.mak: No such file or directory
make: *** No rule to make target 'make_common.mak'.  Stop.
*** GTK2 Build failed.

 

Now I’m confused …

-          Which of the 3 instructions is supposed to be the right one?

-          Is there any value building XULRunner (eg for some Unittests) if I plan to use Webkit instead? If yes, how would I build it properly?

-          With the Libs built from approach 2, I tried running the tests (o.e.swt.tests > Run As > Junit). Many of the 14230 tests do succeed, but it gets stuck in #2962 test_printLorg_eclipse_swt_printing_Printer . I didn’t find a Bugzilla for that … any ideas?

 

For the records, here’s what I installed on my RHEL6 for the build:

yum install gtk2-devel libXtst-devel libXt-devel webkitgtk-devel xulrunner-devel

 

Thanks,

Martin
