It came up with some errors ("overwritten by merge") in demos directory. I just deleted these directories and run batch file again with success (that was probably error in FPCUPdeluxe as well).
After that I just rebuild Lazarus.
I just downloaded and unzipped sources directly but the script is a better idea. I'm using Linux but git commands are the same so I can wrap it into a bash script.
Only thing I didn't do is rebuilding Lazarus. Now I'm trying to do so but it's giving me some error, it says clocale.ppu is missing but it's not. I'm trying to figure it out. Do you think not rebuilding Lazarus might cause my problem?
Try to create new project and see if it works. Also try some simple demos to see if it works.
That way you'll know if the problem is in your app or in Lazarus installation.
I tried a new project and the result is the same. It gets stuck on the title screen, even though it's supposed to be hidden. It doesn't even fire OnCreate event. I added ShowMessage on OnCreate even but it doesn't even show up.
UPDATE:
I reinstalled everything using FPXupDeluxe and it looks like this time it pulled the latest version of LAMW. I fired the update script and I got:
Switched to branch 'master'
Your branch is up to date with 'origin/master'.
HEAD is now at f7178ffc Improved jCanvas component
Already up to date.
I opened my project, it mentioned something about Read Error so as you said, I removed jCanvas, saved the project and added it back. Everything went smoothly. I built the project etc but I faced the same problem, the app doesn't work, it stops at the title screen.
UPDATE #2:
I rebuilt everything one more time and now it seems to be ok, the app ran as it should. Now I'm testing new functions and they work perfectly!
One more time, thanks a lot for your great help!
