Error on compiling to web

1

I tried to compile my game code to web but get this error:

So it something has to do with the used fonts?

Hm, it seems FreeType (library we use to read font files) has trouble processing one the fonts you use. I admit I never saw the error Error -1 while loading glyph but it is evidently emitted by TFontManager.CreateGlyph when FT_Load_Glyph or FT_Get_Glyph (these are FreeType routines to read particular glyph) fail.

I’m happy to investigate it further, but for this we need a testcase. Can you upload a minimal project that demonstrates this problem? Possibly, just creating a new project in CGE editor from “Empty” template, and just using there the TTF font files, will demonstrate the error. You can then zip the project and upload (to this forum thread, or as GitHub issue ).

I’ll be sure to fix it then, or at least advise something useful :slight_smile:

Thank you!

Thanks Michalis, hereby the minimal testcase. It compiles fine in Windows but when I try to compile it to “web” it holds with the errror message above.

Fixed, thank you for the testcase!

  • I added detailed logging - looks like we had trouble reading glyph 170 from Atop-R99O3.ttf.

  • I upgraded FreeType DLLs we use on Windows, and the issue is gone :slight_smile:

As usual, the engine downloads will contain the fixed version automatically in a few hours. You can observe this page, when it will no longer show the commit titled “Update FreeType Windows DLLs to version 2.14.3” then the fix is part of the release. Please download then the new engine version and retry → the issue should be gone :slight_smile:

Thanks, I re-installed CGE newest version but now I get another error (only when compiling to “web”):

I looked up where the pas file is, it is available but not in the path?
(it compiles correctly in Win (default).

@Carring if you have such a setup, which looks incompatible with all web-target requirements (fpc version 3.3, proper pas2js installation) you’d probably need to reinstall everything from scratch, following updated instruction Web Target | Manual | Castle Game Engine , the part where WA-single button installation is described (so latest fpcupdeluxe, ideally new folder for fpc3.3 and WA-button for installation of everything needed, followed with steps in the after install section). Then everything works fine on windows

Thanks.

Ok, I just re-installed everything from fpcdeluxe but still get that error. I think it is now because I do not understand how to add the path, described in the manual. How can I add the path to the configuration?

On starting Lazarus (from “viewmain.pas in the editor) this is shown:

this is simple. here is the standard instruction, on the link.

and it has nothing to do with lazarus.

As for changing your PATH, we also link from our website (e.g. from here) to this overview: https://www.computerhope.com/issues/ch000549.htm . It has screenshots and sections per-Windows-version.

After changing the PATH, remember to restart the applications (if you’re not sure, just logout + login again).

You can test whether a working pas2js is present on PATH by doing a test independent of our engine:

  • Create a Pascal file with such trivial contents:
    begin
  Writeln('Hello from pas2js!');
end.
  • Save it anywhere with any name. E.g. c:/tmp/hello_pas2js.lpr .
  • Run Windows Terrminal (press super + cmd + Enter). In terminal:
    • enter the proper directory (c: enter, cd c:/tmp/ enter)
    • execute pas2js -Jc -Jirtl.js -Tbrowser hello_pas2js.lpr
    • if this goes OK, you should have hello_pas2js.js in the same directory.

See the prerequisites section for more info.
