[Lazarus] on ARM Linux ,SoftFloat and EABI issues
Hi Florian and other friends I am involved in porting existing C code to Arm Linux for AT91SAM9263 Ek board with 340x220 display. I need to write lots of console kinda apps. I am using a qemu-system-arm emulated Armel Debian machine on a Debian x86 Lenny distro for writing code. I installed fpc-2.2.0.arm-linux.tar on the emulated linux. Which compiling a simple helloworld.pas , i get the classic error of System.o being EABI 0 while target is EABI 4. I have got the svn download of fpc, and trying to compile it in the emulated machine for ARM for the past 2 days. I have given :- make clean all ARCH=arm OPT=-CfSoft. Its compiling for quite long and finally comes to rest endlessly while compiling system.pp. Let me remind you that i am dont use a Cross compiler, but an emulated Arm machine. My boss and colleagues are 'C only' programmers . Doing all kinda harware access for embedded devices using C. They have developed pretty good successful apps using pure C without an OS. What i have been trying is to convice them to use Freepascal for the Application part, which is presently console Apps. The next stage is to develop X apps using Lazarus. But for these I need to get FPC working. Please help. regards Nataraj ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Postgres Dlls not found
I don't know what more I can try. It doesn't make sense. Why should the laptop be able to run when the DLLs are copied to the system32 directory, yet the Desktop clients are generating an error message which says that the Postgres Client is not installed (libpq.dll). Could it be that the error message is misleading? Might it be something else which is tripping up the app?

asking for libpg.dll.
Try to copy the libraries in the directory of your application.
The procedure to load the library uses a straight windows loadLibrary call,
as can be seen from the following:
Procedure InitialiseDllist;
begin
inc(RefCount);
if RefCount = 1 then
begin
DllistLibraryHandle := loadlibrary(pqlib);
if DllistLibraryHandle = nilhandle then
begin
RefCount := 0;
Raise EInOutError.Create('Can not load PosgreSQL client. Is it installed?
('+pqlib+')');
end;
So normally it should find it.
Michael.

[Lazarus] Carbon: Simple component in a simple package with strange behavior
Hi all,
Lately I've been trying to create a package with custom components, which
works already on Lazarus Win32, but gets all kinds of errors on Mac OS X, so
I created a package from scratch and try to isolate different problems.
I created a new package and saved it as TestPackage.lpk, added a new
component with TWinControl as ancestor type and named it TCommonTest, named
the unit NewCtrls and saved the unit as newctrls.pas. I added a new
requirement to the package, so that LCL also is required by the new package.
I then manually added a new component to the unit named TComponentTest with
TCommonTest as ancestor, and changed the register procedure to only register
the last component.
It compiles, and the component is installed, and the component is visible in
the tab New Ctrls on Lazarus, which is compiled to Carbon.
But when I try to drop the new component on a form (on a new and clean
application) it fails saying Error moving component
ComponentTest1:TComponentTest. The new component does not appear on the
Object Inspector at first, but clicking on the component tree will make it
appear, and I also can select the component on the form - but nothing is
added to the unit source, and the application can't run because of Class
TComponentTest not found, which naturally is caused by nothing was added
to the units uses clause.
Manually making the changes to the forms unit will cause the application to
raise an exception with the message: (V)TCarbonWSWinControl.CreateHandle
Error:Not implemented - unable to create Carbon win control for
ComponentTest1:TComponentTest!
Does a new component with an ancestor type of TWinControl need special
handling, or is it impossible? Or am I doing something totally wrong?
Thanks and best regards,
Normann

Hi,
I would like to create a new IDE Package that adds a new project type
to the 'File | New' dialog. In the components directory there are a
few examples of this for FPCUnit and fpWeb. What I'm not sure about
is... Can that ide package automatically add a required (external -
not part of FPC or Lazarus) package (fpgui in my case) to the new
project being created? Any clues or example on how to do this?
Yes, of course it can.
See components/projecttemplates/idetemplateproject.pp:
function TTemplateProjectDescriptor.InitProject(AProject: TLazProject) :
TModalResult;
begin
AProject.AddPackageDependency('FCL');
AProject.AddPackageDependency('LCL');
AProject.Title:=FProjectName;
end;

Any idea what should I do in order to make sure that the file location stored in Lazarus settings as well ? Has the 3rd party components a package file (.lpk) and do you use it? Yes, they all have a lpk files for runtime. I use Compile and Install, then it recompiles Lazarus, and restart it with a new version containing the new component(s). What files can not be found? The .lpk or some units? Usually units and include files. How do you compile the package when it works? Is this a design time or run time package? How did you test, that the units can not be found? I either try to use the component on a form, recompile Lazarus, or install another component (using a package). Then Lazarus tells me in a dialog box that a file x was not found. A new project will not use all installed IDE packages. You must put a component on a form or manually add the dependency to the project.

Re: [Lazarus] on ARM Linux ,SoftFloat and EABI issues
2008/5/30 Nataraj S Narayan [EMAIL PROTECTED]: Hi Florian and other friends I am involved in porting existing C code to Arm Linux for AT91SAM9263 Ek board with 340x220 display. I need to write lots of console kinda apps. I am using a qemu-system-arm emulated Armel Debian machine on a Debian x86 Lenny distro for writing code. I installed fpc-2.2.0.arm-linux.tar on the emulated linux. Which compiling a simple helloworld.pas , i get the classic error of System.o being EABI 0 while target is EABI 4. I have got the svn download of fpc, and trying to compile it in the emulated machine for ARM for the past 2 days. I have given :- make clean all ARCH=arm OPT=-CfSoft. the makefiles use CPU_TARGET, but this shouldn't be necessary when you're compiling natively (or inside an emulator, even). i'd recommend going the cross compile route (since i know that works with trunk). just compile binutils (./configure --target arm) and compile fpc with: make crossall CPU_TARGET=arm CROSSOPT=-CfSOFT you can use other envvars, too, just inspect the makefile if you're brave, or read the buildfaq for some good info. henry ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

You should first set the client_encoding with
'TSQLConnection.ExecuteDirect('set client_encoding to ''gbk'');'
Then you can open your query. (Note that you can only change the
