“Gtk WARNING: gtk_disable_setlocale() must be called before gtk_init()” on calling plot in gdl (gnu data language) #969

Closed jyothischandran1597 closed 3 years ago

jyothischandran1597 commented 3 years ago

I installed GDL to run some IDL code for my project. But when I try to call the plot function in GDL it gives the following error and exits:

(gdl:1003695): Gtk-WARNING : 22:57:44.888: gtk_disable_setlocale() must be called before gtk_init() Segmentation fault (core dumped)

I am using ubuntu 20.04 with kubuntu-desktop. Any suggestions are welcome.

On starting GDL, the text I get is:

_(gdl:484266): Gtk-WARNING **: 19:24:59.488: Theme parsing error: colors.css:71:52: Expected ')' in color definition

I have tested and apparently this comes from a clash between wxWidgets 3.1.5 and the plplot library.

jyothischandran1597 commented 3 years ago

So, which versions of wxWidgets and plplot I should use to correct this?

jyothischandran1597 commented 3 years ago

Actually, I am able to plot now. I just compiled the plplot to /usr/local/ and provided the path while compiling gdl.

But, when I run check, two tests are failing always.

99% tests passed, 2 tests failed out of 189

Total Test time (real) = 73.77 sec

The following tests did not run: 100 - test_grib.pro (Skipped) 126 - test_mpi.pro (Skipped)

The following tests FAILED: 93 - test_fixprint.pro (Failed) 184 - test_window_background.pro (Failed) Errors while running CTest make[4]: [Makefile:118: test] Error 8 make[3]: [testsuite/CMakeFiles/check.dir/build.make:59: testsuite/CMakeFiles/check] Error 2 make[2]: [CMakeFiles/Makefile2:222: testsuite/CMakeFiles/check.dir/all] Error 2 make[1]: [CMakeFiles/Makefile2:229: testsuite/CMakeFiles/check.dir/rule] Error 2 make: *** [Makefile:214: check] Error 2

Yes, see end of the #961 conversation, recompiling plplot after wxwidgets removes the core dump. We (at last I) are investigating, as this endangers the possibility of a version 1.0 of GDL. I understand that the Gtk-WARNING **: 19:24:59.488: Theme parsing error: colors.css:71:52: Expected ')' in color definition have disappeared as well?

jyothischandran1597 commented 3 years ago

Thank you. Nope. I suspect the color.css warning happens because I am using some custom themes in KDE desktop. For them to go away, I have to manually edit out an extra value that appears like rgb(.. , .. , .. , 216) from colors.css.

GillesDuvert commented 3 years ago

@jyothischandran1597 Apparently with 4 values it should be written as rgba(r,g,b,a) not rgb(r,g,b,a)

jyothischandran1597 commented 3 years ago

I think the comment in https://github.com/gnudatalanguage/gdl/issues/961 by @GillesDuvert to compile plplot after wxwidgets does it for this problem. Now I am comfortably running gdl with HEALPix IDL, even using jupyter kernels. Now, only if gdl has idl functions like TS_SMOOTH, everything would be perfect!

jyothischandran1597 commented 3 years ago

Also, in rgba the a which is alpha is between 0 and 1. In my colors.css file in ~/.config/gtk-3.0 the 4th value was 216 for multiple lines. when i edited that value out, everything works fine as far as i know.

I'm seeing the same test failures with latest gdl git. Worth opening a separate issue for those?
