scilab 6 has a bug related to jogl jar library, if mesa version is >= 17.2 then scilab will be unable to use graphic hardware acceleration, no graph plotting,

http://forum.jogamp.org/Mesa-17-2-0-renderer-driver-name-change-error-causes-GLProfile-not-mapped-initialization-error-td4038176.html

in the console we can read these error logs : javax.media.opengl.GLException: X11GLXDrawableFactory - Could not initialize shared resources for :0 at jogamp.opengl.x11.glx.X11GLXDrawableFactory$SharedResourceImplementation.createSharedResource(X11GLXDrawableFactory.java:317) at jogamp.opengl.SharedResourceRunner.run(SharedResourceRunner.java:295) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.NullPointerException at jogamp.opengl.GLContextImpl.makeCurrent(GLContextImpl.java:625) at jogamp.opengl.GLContextImpl.makeCurrent(GLContextImpl.java:539) at jogamp.opengl.x11.glx.X11GLXDrawableFactory$SharedResourceImplementation.createSharedResource(X11GLXDrawableFactory.java:293) ... 2 more

the solution is to build scilab with a beta version of jogl (2.3.3), or to disable gpu hardware acceleration :

export LIBGL_ALWAYS_SOFTWARE=1

In order order to update (and/or build), you may need to uninstall scilab then build it and finally reinstall it to avoid conflicts between the two versions.

For now, scilab fails to run when launched from outside a terminal.

I just build and installed scilab for the first time. Unfortunately I cannot run it. I get an error: Error parsing gtk-icon-sizes string: ''

Does anybody experiences the same error? I am running xfce on latest arch. Furthermore I tried the same on my laptop with manjaro+xfce. Same result.

Edit: It seems that this issue is not xfce-related. I evaded the gtk error as suggested in the xfce forum. Now I don´t get any error anymore but still scilab won´t start as described before.

Edit#2: I removed this package and installed scilab-bin instead. Somehow, it works now. Note: I also tried to make different jdk versions default before. This also didnt make a different when trying to start scilab.

@ragoreco @tavla I found a solution, having the same problem before. Go into the directory where the Scilab aur package was downloaded, into src/scilab-6.0.2 or such, and edit ./modules/xml/src/cpp/XMLDocument.hxx Around line 26 will be "extern C {". remove that, as well as the next closing bracket.

There's also another of the same error. Just do the same thing with: ./modules/scicos/includes/XMIResource.hxx

After that finishes, run sudo make install.

I believe the reason for the error is some changes in xml.h that now has c++ code in it or something, conflicting with the whole "extern C" stuff.

version scilab 6.0.2-1 - multiple compile-time errors like "template with C linkage", for example: /usr/include/c++/9.1.0/memory:146:1: error: template with C linkage 146 | template <typename _Tp> | ^~~~~~~~ ...... make[3]: [Makefile:1147: src/cpp/libscicompletion_algo_la-XMLFieldsGetter.lo] Error 1 make[3]: Leaving directory '/tmp/yaourt-tmp-element/aur-scilab/src/scilab-6.0.2/modules/completion' make[2]: [Makefile:815: all] Error 2 make[2]: Leaving directory '/tmp/yaourt-tmp-element/aur-scilab/src/scilab-6.0.2/modules/completion' make[1]: [Makefile:827: all-recursive] Error 1 make[1]: Leaving directory '/tmp/yaourt-tmp-element/aur-scilab/src/scilab-6.0.2/modules' make: [Makefile:1601: all-recursive] Error 1

I've been trying to install Scilab from AUR, and all goes well until it starts linking. I have the following error: In file included from src/cpp/XMLDocFieldsGetter.hxx:24, from src/cpp/XMLFieldsGetter.cpp:24: ../../modules/xml/src/cpp/XMLDocument.hxx:26:1: note: 'extern "C"' linkage started here extern "C" ^~~~~~~~~~ make[3]: [Makefile:1147: src/cpp/libscicompletion_algo_la-XMLFieldsGetter.lo] Error 1 make[3]: Leaving directory '/var/tmp/pamac-build-rgonzalez/scilab/src/scilab-6.0.2/modules/completion' make[2]: [Makefile:815: all] Error 2 make[2]: Leaving directory '/var/tmp/pamac-build-rgonzalez/scilab/src/scilab-6.0.2/modules/completion' make[1]: [Makefile:827: all-recursive] Error 1 make[1]: Leaving directory '/var/tmp/pamac-build-rgonzalez/scilab/src/scilab-6.0.2/modules' make: [Makefile:1601: all-recursive] Error 1 ==> ERROR: A failure occurred in build(). Aborting...

Is anybody having the same issue? Can someone indicate me how to fix this error?. I know I can go Scilab website and download the package, it works fine. However, I want to get it installed from AUR.

Thanks

People, i tried install the scilab, but this error appeared: .cache/pacaur/scilab/src/scilab-6.0.2/modules/graphic_objects/src/java/org/scilab/modules/graphic_objects/xmlloader/CSSParser.java:17: error: package javax.annotation does not exist

Can someone help me?

Thanks

@Xwang: sorry, I forgot to test in a clean chroot...

I had to install time to solve a compile error (/usr/bin/time not found). I suggest to add time to the compile depends.

Build Error cannot satisfy apache-ant>=1.9 Changed buildfile to ant>=1.9 and it builds and installs.

Start from start menu but immediately exits.

Anyhow it starts from commandline ....

Builds fine here.

Hello,

It's seems that the PKGBUILD bug in "package()" after this step : "Buildfile: /tmp/pamac-build-adrien/scilab/src/scilab-6.0.1/modules/graph/build.xml".

Thank for help.
