Does not install in linux #10

Open ghost opened 4 years ago

"Does not install in linux" does not help the developer fixing the problem. So maybe try this template:

Expected behavior

Actual behavior

Steps to reproduce the bahavior

Or maybe I can fix the problem then.

Best regards BoAnd

Hi,

The install failed for me on CentOS 8 (x86_64 ) with the below error. I'm installing from the /tmp directory.

/tmp//src/tools/PaletteTool.cpp: In member function ‘void PaletteTool::AddColor(const wxColour&, const wxString&)’: /tmp/colorgrab/src/tools/PaletteTool.cpp:176:35: error: call of overloaded ‘wxVariant(const wxColour&)’ is ambiguous data.push_back(wxVariant(color));

@P4ulJC Could you try building the develop branch instead? I think I've seen the error before and fixed it in this commit.

P4ulJC commented 4 years ago

I tried building the develop branch and it compiled without errors! But unfortunately I can't use it because no colour pickers work on CentOS 8. I've tried 5 different ones! The picker does not work outside of the app window - so it can't pick anything apart from the app itself (and even then colours are not picked - same with all apps). This is common to all programs - including the Gimp's colour picker. It's related to Wayland I think - I know nothing about Wayland apart from the fact you can't use colour pickers with it!

nielssp commented 4 years ago

Yeah, unfortunately I don't think Wayland allows applications to take screenshots/read pixels from the screen. Last time I looked into it I couldn't find a way around that.

P4ulJC commented 4 years ago

Yes you are right about Wayland and I wish I'd known that before I started installing 5 different colour pickers! I think Grim is the thing to use with Wayland to grab the screen. I'm part way through installing dependencies for it - but have given up for the moment after a dependency of a dependency needed updating and I couldn't get the new version to install without a few other dependencies.... I think it's called Grim because it's such a grim task trying to install it...

RokeJulianLockhart commented 2 years ago

If the problem is caused by Wayland and/or CentOS, why not report this problem to the developers of those projects and consequently close this issue?

P4ulJC commented 2 years ago

I forgot all about this because I ditched Wayland the following day due to how many issues I was having. Apologies for leaving it so long. I know nothing about Github apart from making the occasional comment like this - not sure if I close the issue or what...
