3) Packages have their own custom options and can add custom options to
the project.

Is it true to say that there are only 2 ways in IDE to set defines.
1) Project Options/Custom Options
2) Project Options/Additions and Overrides (+ Custom Option)

No I did not add the -d in front of the UseCThreads symbol, just the
symbol itself.

I used Menu: Project/Project_Options/Compiler_Options/Custom_Options
This was the only place I found the word Defines, which appears on a
button to the right. It is in subnode Compiler_Options, which did not
sound right to me anyway since I wanted the symbol to be global
including the Lazarus IDE code parser, but I did not find defines
anywhere else...

Then I clicked the button and an input dialog named Defines popped up.
It has a text input box named Define into which I typed UseCThreads
Then I clicked the Add button and this name appeared in the list
below, so I clicked OK and the input dialog disappeared and I was back
in the Custom_Options dialog with nothing showing in the list there.
If I cancel at this point everything works out except for the define
but on the second try I clicked OK and then Lazarus locked up.

I see a checkbox "Build modes" on top of the Custom_Options dialog, is
this the box you mean? I have not checked it.

It should not be any different, Lazarus itself uses the same sources
on all plöatforms as far as I understand. I retrieved 1.6RC2 from svn
when I built Lazarus.

Different workaround solution:

If I open the project file and add this directly on the next line
following the top line "program MyTCPTest":
{$DEFINE UseCThreads}

then it actually does work.
But the Delphi way seems easier with a separate project option for the
defines...

When I added

as the first line following the program line it works.

All linux flavors have this as well. In kUbuntu it is called system
monitor (underlying name is ksysguard).

use ps command (ps --help all) to get PID's.  ps aux is a good start,
but use grep to winnow it down.

Tried this:
pi@rpi2-jessie2:~ $ ps -u pi |grep lazarus
 5091 ?00:00:00 startlazarus
 5094 ?00:00:10 lazarus

Seems to be two processes with lazarus in the name.
Which one (or both) do I kill?

`killall` takes the name of the process, and tab completion works on
most systems I've tried.

If you use the defines button, make sure the checkbox next to

I would assume the higher PID is the child of the lower. You can also
specify --forest with the ps command and it gives ascii art tree showing
parent child relationships.

I'm no linux expert but I would kill child first then parent. But it may
be killing parent automatically kills child.?.

Then again you can use (at least in kUbuntu) the system monitor to kill
processes, right click on the entry on the processes tab.

man top ;)



'top' command is your friend
then

k for kill
then the signal to kill
9 for termination ;)
15 for asking polite to close ;)

[Lazarus] How to set defines for a project? Lazarus crashes...

[Bo Berglund]

I tried setting the conditional "UseCThreads" for my test project but
even though I can reach the place where this apparently is set:
Menu: Project/Project_Options/Custom_Options/Defines
it seems not to work!

When I use this dialog to enter the symbol UseCThreads the effect is
invisible when I hit OK, nothing gets added to the list of
defines/options and when I OK on the main options window anyway
Lazarus locks up completely!!!
Only way out seems to be to reboot the machine!
I have not fond any way to open a menu or interact with the Lazarus
IDE any other way after this happened so now my option is to restart
the operating system.
It IS still possible to move the Lazarus windows around on the desktop
but not to close Lazarus or interact in any other way. :(

Is it not supposed to be possible to use this dialog that clearly
offers to add a define to actually do this?

In Delphi this is available in a dialog along with the path settings,
which is very convenient to use...

I am using Lazarus 1.6RC2 and FPC 3.0.0 on Raspbian Jessie.

reboot ist not needed on linux
use a console and kill command
Ctrl-Alt-F1 for console
and 
Ctrl-Alt-F7 to go back to X

UseCThreads is normaly added in the *.lpr file
Project->Project Inspektor
 doubleclick lpr file

Do you mean you added -dUseCThreads in Project/Project_Options/Custom_Options,
but it is not appended to options passed to FPC?

Did you enable the checkbox of the define?

It works here on OS X/carbon. Maybe the bug only appears on your platform.
