Cannot Specify Printer4Lazarus in Project Inspector
lazarus / 9-Editor
----------------------------------------------------------------------
Dan3468298 · 2020-07-05 01:16
I installed Printer4Lazarus (see first attached image) yet cannot
specify it as a Requirement in Project Inspector because the package
is listed as Online. I have tried to remove and re-add to no avail.
I am not sure if my Package Manager became corrupt because I could
spec the Printer4Lazarus in another project.

As your printer woes seem to be related to your earlier thread, if it
was me, I would uninstall Lazarus, delete the .lazarus (dot lazarus)
directory in your home directory and then reinstall a fresh copy of
Lazarus.

Is it really listed as online? Maybe it already is a dependency for
your project through some other package.

The screen shots are for a new project with only the default code. I
previously had Lazarus pre-2.0.8 installed on Mac OS but couldn't get
it to run because of linking errors so after awhile I did a complete
uninstall with the wiki script then installed 2.0.8. All worked fine
until tried Printer4Lazarus. See attached for new screen shot that
explicitly shows Lazarus thinks the Printer4Lazarus is Online though
PackageManager lists it as Installed. After removing Printer4Lazarus
it is marked with a Red 'x', why? (see second screenshot). Thanks!

There is something wrong in your installation or configuration. Please
see my screenshots. Printer4Lazarus shows there as expected. It is not
online and I can add it as a new project dependency to one of my test
projects. No problems.

Good question. The packages have many icons to indicate their state
and purpose. I don't remember what the red 'x' means. Somebody else
may remember (wp maybe).

I did an uninstall using the script from Wiki then deleted .Lazarus in
home folder and Lazarus folder in Library. Downloaded files again
installing FPC, FPC Source, then Laz. Ran Laz and with default code
tried to add Printer4Lazarus to new project but it is still marked as
Online. How can this be? Are there other files that have to be
removed that are not documented?

The icon in question is named pkg_package_uninstall.png. The L overlay
indicates that it is a Lazarus package (the icons used are all in
.../Lazarus/images/packages).

I can confirm that this appears to be a bug.
Fresh installation of Mojave in a VM with Xcode, Xcode command line
tools, Lazarus 2.0.6 and FPC 3.0.4.
Attachment 1 - shows Printer4Lazarus is installed
Attachment 2 - shows Printer4Lazarus as "online" and not installed
Attachment 3 - shows attempt to Install from Project Inspector
Error message when compiling otherwise blank project after adding
printer4lazarus to uses clause of project source:
QuoteCompile Project, Target: project1: Exit code 1, Errors: 1
project1.lpr(10,10) Fatal: Cannot find printer4lazarus used by

As the original poster indicated, I cannot add Printer4Lazarus using
the Project Inspector.
The workaround was to manually add it to the project.lpi file
changing:
Code: XML [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
to:
Code: XML [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
I also tried Lazarus 2.1.0 (trunk r63272) with FPC v3.3.1 (trunk
r45525) on Mojave with the same results.

Thank you Trev. Your workaround worked for me on Catalina.
----------------------------------------------------------------------
skalogryz · 2020-07-06 14:16
you can also Open the package (through "Installed Packages" dialog)
and click "Use"->"Add to project"
----------------------------------------------------------------------
Dan3468298 · 2020-07-06 14:31
Please excuse my ignorance but where do I find the 'Installed
Packages' dialog? This should be under the 'Package' menu?

Sorry, I meant Packages -> "Open Loaded Packages"
It should give you the list of IDE installed packages. When you double
click one any of those it will bring up the package dialog.

I would think so. Usually the person who encounters the issue would
log an issue in the BugTracker. If you do not wish to do so, I'm happy
to do it.
As there is a workaround, you might also wish to mark this thread as
[SOLVED] by modifying the post title in the first post.

It must be specific to MacOS somehow. Can you please verify that it
happens only on MacOS. Does widgetset (Carbon / Cocoa) make a
difference?

I only have access to MacOS Catalina so Carbon will not run on my
machine.

I can confirm that the issue does not occur with FreebSD 12.1, FPC
3.3.1 snapshot from June 2019 and Lazarus 2.0.6 or 2.1.0 (trunk) using
the GTK2 widget set.
[EDIT]
Lazarus v2.1.0 r61574 with GTK2 widget set, FPC v3.0.4, Ubuntu 18.04
is also OK.
[/EDIT]
----------------------------------------------------------------------
JuhaManninen · 2020-07-11 07:53
Yes I believe it is a bug as many people can reproduce it in MacOS. I
wonder what makes it OS or Widgetset dependent. I don't have a Mac and
cannot test myself.
Please report in bug tracker with all details.
----------------------------------------------------------------------
trev · 2020-07-11 08:34
Verified it did not happen with Lazarus compiled with 32 bit Carbon,
but does happen with Lazarus compiled with 64 bit Cocoa (tested on
macOS 10.11.6).

Trev, thank you for your good work!
----------------------------------------------------------------------
JuhaManninen · 2020-07-12 08:05
This is fixed now.
It was a clear error of memory access caused by wrong typecasts. It
was not specific to OS or Widgetset but it caused more trouble in some
systems as memory bugs often do.
It is good for code to be tested in many systems. More bugs are
revealed.
