[SOLVED] Can't compile my project after updating to LAZARUS 4.0

[the_magik_mushroom]

Hello everyone,
I've moved to a new computer, installed lazarus 4.0, all my components,
but now I can't compile / view my form with F12 of my program I've been working for years now...

First I get this message when trying to view my form in the IDE:
Confirm changes
The following units will be added to the uses section of
C:\Users\User\Desktop\PROG\unit1.pas:
SynGutterBase

then I have a window FIX LFM file:


Is all these error coming from SynEdit? What can I do?
Thanks

edit: found it, I had a missing component, I think it was EncConv...

same with version 3.8. now I'm panicking

Hi
Are you maybe missing a 'syn'-package or 2, in the 'Project Inspector', under requirements?!?

Wow, that is a big lfm....

I don't think the errors show the correct location. Comparing with a new synedit on a form that looks normal (and loads in 4.0).
I guess that there is something wrong further up.


I don't know what you have in terms of backup. If you don't, then copy the backup folder created by Lazarus. It may just still contain something....

Yup!

found it, I had a missing component, I think it was EncConv, so the lazarus error messages were wrong/misleading.

I'm going to be paranoid next time I change my computer, is there a simple / bulletproof way of saving all the extra components and modified files in one shot and restore everything easily?

Anyone doing it?
ChatGPT suggested to write my own script:

Code: Pascal  [Select][+][-]

1. @echo off
2. set LAZARUS_DIR=C:\Lazarus
3. set PACKAGES_DIR=C:\LazarusComponents
4.  
5. REM Compile and install each package
6. %LAZARUS_DIR%\lazbuild.exe %PACKAGES_DIR%\MyComponent1\MyComponent1.lpk
7. %LAZARUS_DIR%\lazbuild.exe %PACKAGES_DIR%\MyComponent2\MyComponent2.lpk
8.  
9. REM Rebuild the IDE
10. %LAZARUS_DIR%\ide\lazarus.exe --build-ide=

Copy your config directory, when you upgrade lazarus it will ask you to upgrade the config, afterwards just recompile.

Or even better, instead of installing a new lazarus version, just update your existing one. E.g. using git:

Code: Bash  [Select][+][-]

1. $> git fetch --all # load all updates
2. $> git checkout lazarus_4_0 # Update to 4.0
3. $> make clean lazbuild # step 1 build lazbuild
4. $> ./lazbuild --build-ide= # step 2 build the IDE
