Hi Folks.

I've installed Lazarus 1.0.8 and FPC 2..6.2 on two newly created Linux x86_64 VMs
One is a OpenSuse 11.4 and the other one is a 12.2 Install on both machines was as I like to say when all runs well, the fingers in the sose and the hands in the pocket 8-) Recompile IDE with all my needed packages: beautiull. Run tests: great ! I really appreciate
BUT:
on the form of an application (btw, multi-threaded + Indy 10) drop a common TButton on the main (and only) form: OK.
When trying to assign an event to it: BOUM >:o

the LCLClasses unit is displayed and the next error is displayed in the errors window:

????????????????
No way to assign an event to a new TButton.
Same behaviour in both machines. What happens ?

Antonio.

If you view your project in the Project Inspector, is the LCL shown as a required dependency?
If not, it should be added.

Something is wrong with your installation of fpc and/or fpc-src.

Please check via menu 'View / IDE internals / About FPC' and 'About IDE'.

Yep, both are there: LCL and IndyLaz
BTW, I've installed Lazarus 1.1 an,d FPC 2.6.0 on the 12.2: besides some IDE problems, project compiles and runs. Adding new TButton and assigning evaents is a piece ok cake.
The version before was 1.0.5 which did work too.

Looks fine, no error lines. Something special to look for ?

In the 'About FPC' should be lines like:

classes=/usr/lib/fpc/2.6.2/units/x86_64-linux/rtl/classes.ppu

Sources:
Directory=/usr/share/fpcsrc/2.6.2
Files.Count=11316

Check on your disk that "Directory" contains many "classes.pp".

Have you tried "Tools / Rescan FPC source directory"?

Have you tried "Tools / Rescan FPC source directory"?

Yes, still same behaviour

This is the line:
classes=/usr/lib64/fpc/2.6.2/units/x86_64-linux/rtl/classes.ppu ?

> Sources: > Directory =/usr/share/fpcsrc/2.6.2 > Files.Count=11316

What file count do you see?

Linux uses the one for unix.

What values do you have under "Active Target" and "FPC executable"?

OK

Active target:
TargetOS=Linux
TargetCPU=x86_64

FPC executable?

Sorry Guys.

I have to apologize because I guess it is my fault. After the install process I have overwritten some of the config files in ~/.lazarus by other files coming from another Linux installation which works. Unfortunately the source installation was not exactly the same as the very new one.
I already used that trick with success for new installations to save Lazarus configuration time. But this time the paths, parameters, etc. were all the same.
In this case some of the critical paths between the source and target Lazarus were not identical.
I'll install and cofigure all and I'll keep you informed about the final situation.

Thank you anyway, your questions helped me to find the error. Thans again.

Antonio.

Bad news.

I have unistalled and re-installed Lazarus again:
lazarus-1.0.8-0.x86_64.rpm.
~/.lazarus removed
Change some options of the editor to my usual requirements Recompile all needes packages.
Load the project on which I'm currently working.
Compile, rebuild: OK
So far so good.
Add a TButton on main (and only) form
double-click on it: same error window and error message asking for TComponent in LCLClasses.pp tagged as read only (sounds reasonable as all files are root owned and "r-x" for group and others. I've done a
# chown -R sita:users /usr/share/fpcsrc/
but nothing changed

Antonio.

Another strange behaviour is that lots of types are not recognized: On my own units as well on Lazarus units, setting the cursor on the word TPanel using the key Ctrl does not undescore the TPanel and Ctrl+Left click has no effect.
Even my own types are not known although the unit is the uses clause and the program compilation looks OK

Antonio.

:)

As they should be when installing an rpm.

I've done a # chown -R sita:users /usr/share/fpcsrc/

You should undo this.
I'm curious. Why do thought that a "can not find unit" error can be fixed by giving write access? You are not the first doing so. Is there some misleading error message?

but nothing changed

You seem to have a very standard setup, except for your extra packages. What extra packages do you install?

Mattias

Do you mean /usr/bin/fpc?

Mattias

Everything that uses the classes unit suffers.
Try the Ctrl key over the uses section. Can you jump to 'sysutils'?

yep

Indy 10
IBO (Firebird access and controls)
daemon: for that one I've had to chown to myuser to be able to compile it !! After changing the owner, daeon did compile and install

Le 03/04/2013 11:14, Mattias Gaertner a ?crit :

yes, and Classes too
When I Ctrl+Left click on a TObject descendant of TObject, nothing happens But Ctrl+Left click over a local method variable, brings the curson on the variable definition

It seems at some point I lost you.
I thought the IDE can not find unit classes.
Please use instead of Ctrl+Left Click, the popup menu: Click Left to position the blinking cursor, then right click 'find declaration'. This will give an error message.

Mattias

Sorry Guys, I will have to leave for a while, I have to solve a very urgent problem. I'll be back soon.

Antonio.
