[Solved]QT5: can't compile lazarus trunk (revision/hash: 8035014eaf)

[zoltanleo]

Hi folks.

I try compile  fpc trunk(revision/hash: eac6add9f7)  lazarus trunk (revision/hash: 8035014eaf) on Kubuntu via fpcupdeluxe. I get error:

Code: Pascal  [Select][+][-]

1. home/leyba/laz_dev/lazarus/ide/lazarus.pp(169,1) Error: (9013) Error while linking
2. /home/leyba/laz_dev/lazarus/ide/lazarus.pp(169,1) Fatal: (10026) There were 1 errors compiling module, stopping
3. Fatal: (1018) Compilation aborted
4. make[2]: *** [Makefile:4779: ide] Error 2
5. make[1]: *** [Makefile:3106: ide] Error 2
6. Error: /home/leyba/laz_dev/fpc/bin/x86_64-linux/ppcx64 returned an error exitcode
7. Error: (lazarus) Build IDE: stopped with exit code 2
8. Error: (lazarus) Building IDE: Building IDE failed.
9. make: *** [Makefile:3113: useride] Error 2
10. fpcupdeluxe: ERROR: Lazarus Native Installer (BuildModuleCustom: UserIDE): make returned exit status #512.

What's the matter, please tell me?

You are missing libQt5Pas, and the distro one is old, you must build your own or wait lazarus 3.0

This GitHub repro has newer libQt5Pas

My too, error compile QT5 via download gitlab fixes_3.0.zip, OS Kubuntu,
but, via download gitlab fixes_2,.2.7.zip success install with QT5

[zeljko]

But what is exact linker error ? Only "linking error" means nothing.

Ok, fix
Thanks AlexTP

You didn't guess

I have independently generated and installed the "new" libqt5pas. Then I tried to use files from Davo. The result was always negative.
Then I guessed to put the qt 5 pas files next to the fpcupdeluxe executable. The assembly was successful.

Thanks for attention.

Hi ecrypt.

You can also try to build and install libraries yourself in this way

Thats because fixes_2_2_7 does not include some quite significant improvements that zeljko has made.  I believe you most certainly want the better code in fixes_3_0.  And that requires you to either use the newly compiled libqt5pas from https://github.com/davidbannon/libqt5pas or to build and install them yourself, source and instructions are in the fixes_3_0 source code. 

If you are building lazarus QT apps, you need both the library and the dev library, your end users will need only the Library. Right now, very few if any distros will have the up to date library in its repo. Debian, for example, will not have the new libraries anywhere in its repos until the version 3.0 of Lazarus is released.
