Okay, installed 1.0.10, recompiled lazarus, that fixed these problems.

Now the only problem is that whenever I try to build a project originally created earlier, it says
"Fatal: Can't find unit interfaces"

I checked the FAQ entry on it, to no avail.

New projects work fine, but I have some projects from earlier dates that I vitally need to be able to work on again.

They used to work fine anyway.
I deleted all the .ppu and .o files from the directory, no luck whatever is wrong is somewhere in the .lpi's or .lrs's.

Any suggestions ?

Solved in private mail comminucation.
Forwarded to list in the hope the will end up in a searchable archive once.

ppc386 -h reveals:
Free Pascal Compiler version 1.9.0 [2003/11/05] for i386

Which is the latest I could find on the freepascal website. The reason I downloaded from there and not from the lazarus site is that lazarus site only has RPMS, I am on slackware, and the fpc rpms are notoriously incompatible with rpm2tgz (as I learned from experience) so I downloaded the "one big tar file" - picking the latest one I could find.

The used compiler is definitely the cause of your problem. The 1.9.x fpc compilers are beta's for the coming 2.0 version, and beta's ought to have some bugs in them. ;-)

There are four options for you.
1. Use fpc 1.0.10, which you can download from
http://www.freepascal.nl/down-linux-i386.html.
2. You can upgrade your compiler to 1.9.1 by downloading a snapshot from http://www.freepascal.org/develop.html#snapshots.
3. You can get the latest 1.9.1 using cvs. For instructions see: http://www.freepascal.org/develop.html#cvs.
4. You can get until a new 1.9.x compiler is released. I don't know when this will happen, but this could take another month.

HTH,
Vincent.

Fpc 1.9.0 has some problems ("Failed to create pipe"), and some fpc 1.9.1 from last week, cannot read xml files.

What version (and date) of fpc are you using?

HTH,
Vincent.

FYI: The reason, why the codetools can find your existing onclick, but not the objpas, is that they do not compile like fpc. They parse and search units on the fly. This feature is important for speed and to work with code under construction.

This is equally true of new buttons in existing and new forms. Any idea what is causing this or how to fix it ?

- Maybe the IDE didn't notice, that you updated your fpc. Try Environment -> Rescan fpc source dir.
- If this does not work, check if the IDE actually found the objpas unit. There are quite a lot of fpc units, so the easiest way is to grep in ~/.lazarus/inputhistory.xml for objpas.
For fpc 1.9 there should be a line

objpas <your fpc src path>/rtl/objpas/objpas.pp

Is it there?

Hi all, thanks for all the help with the previous issues.

Now a new issue has reared it's ugly head.

When I am working on buttons already in the existing code, I can modify their OnClick methods no problem.
However, I cannot add any buttons. I add a button, I go to events, double click in OnClick and get a message: Cannot find method. The message window shows: Unit not found objpas.

This is equally true of new buttons in existing and new forms.

Any idea what is causing this or how to fix it ?

right

so I checked /usr/src/fpc/rtl/linux There is no objpas.pp there !!

And there should not be. But once it was there.
So, either the rescan did not work (which I doubt, but to make sure, check the file date), or the heuristic found something there. Can you give me a
find /usr/src/fpc/ | grep objpas.p

This is the recent file list.

:(

Everything seems to work now, but I am rather less than happy about it, somewhere something is still looking for the file in the wrong place, I now tricked it into finding it - but I would obviously prefer to just fix it.

No problem. As soon as I found out, what confused the search algorithm. The current 1.0.11 works fine. Do you know the date of your tarball?

> Any idea what is causing this or how to fix it ? - Maybe the IDE didn't notice, that you updated your fpc. Try Environment -> Rescan fpc source dir.

Did that several times, I was thinking along the same lines. I also did make clean all && make
Just in case.

Well I use 1.0.10
ok cd ~/.lazarus
cat inputhistory.xml | grep objpas
<FileDialog Width="441" Height="469"
InitialDir="/usr/src/fpc/rtl/objpas/">
<Item1 Value="/usr/src/fpc/rtl/objpas/"/>
objpas /usr/src/fpc/rtl/$(#TargetOS)/objpas.pp
typinfo /usr/src/fpc/rtl/objpas/typinfo.pp
math /usr/src/fpc/rtl/objpas/math.pp
objpas /usr/src/fpc/rtl/$(#TargetOS)/objpas.pp
typinfo /usr/src/fpc/rtl/objpas/typinfo.pp
math /usr/src/fpc/rtl/objpas/math.pp

So several lines reference the name, some the directory and one the actual objpas.pp file

The /usr/src/fpc bit should be correct, it is actually a symlink to /usr/src/fpc-1.0.10
I led me do some more checking, TargetOS must obviously be linux so I checked /usr/src/fpc/rtl/linux
There is no objpas.pp there !!

Yet /usr/src/fpc/rtl/objpas does exist.

This source directory exists as extracted from the "one big tarball" download's setup script.

I then proceeded to dig into the tarbal itself and can confirm that the file does not exist there either.

I did some further grepping in the .lazarus directory, found this refference in environmentoptions.xml

<OpenFiles Max="10" Count="1">
<Item1 Value="/usr/src/fpc/rtl/objpas/objpas.pp"/> </OpenFiles>

No other reference in that file, and this one does have the right path.

Finally, not being able to figure out where the wrong path was set from, or how it got there, I tried a little hack - I symlinked all the files from /usr/src/fpc/rtl/objpas/ INTO /usr/src/fpc/rtl/linux

Everything seems to work now, but I am rather less than happy about it, somewhere something is still looking for the file in the wrong place, I now tricked it into finding it - but I would obviously prefer to just fix it.
