Hello,

frequently I need to use a function that is missing in FPCMacOSAll.pas. Trying to declare it myself usually results in successful compilation and linking, but most of the time the functions crash at run time. So I wonder if these are not implemented or if I declare them wrong.

Today I need the function FSMountServerVolumeSync and I declared it
like this:
function FSMountServerVolumeSync(const url:CFURLRef;
     const mountDir:CFURLRef;
     const user:CFStringRef;
     const password:CFStringRef;
     const mountedVolumeRefNum:FSVolumeRefNumPtr):OSStatus;
  external name '_FSMountServerVolumeSync';

It compiles and links but it crashes (access violation).

What am I doing wrong? Is this only for Cocoa? How can I make it available?

Previously, I have been successful with the following function:

function LSOpenItemsWithRole(
           const (*var*) inRef: FSRef;
           const inItemCount: CFIndex;
           const inRole: LSRolesMask;
           const inAEParam: UInt32;
           const inAppParams: LSApplicationParameters;
           const outPSNs: ProcessSerialNumberPtr;
           const inMaxPSNCount: CFIndex
           ): OSStatus;
external name '_LSOpenItemsWithRole';

This function, too, is listed as available in MacOS X but not available in CarbonLib.

What's the difference between these two functions, I wonder ...

Cheers,
Tobias

I think you foget to use correct calling conventon modifier. As I know you should use 'mwpascal' modifier.

Best regards,
Paul Ishenin.

Hi,

thanks very much, it works now!

I created a new unit for my declarations and just copied the whole compiler instructions block from FPMacOSAll.pas:

{$mode macpas}
{$packenum 1}
{$macro on}
{$inline on}
{$calling mwpascal}

So now I have access to a whole range of super advanced additional stuff like FSMountServerVolumeSync ;=)

Cheers,
Tobias

Hi,

i just tried to compile a cross compiler
linux 386 to linux arm
(Suse 11.1 to a SSV DIL Net PC / 9200 Atmel AT91RM9200)

I downloades the latest :
.....
Download Daily Source Snapshot of the Fixes Tree
Entire fpc sources archive of the fixes branch: fpc.zip (24 MB) from the website
......

Also... and there i am not sure:
Package Binary
GNU Binutils arm-binutils-2.16-1.i386.rpm
and install it.

Then i started the compiler (as root ???) with :
make clean all CPU_TARGET=arm OS_TARGET=linux
BINUTILSPREFIX=/usr/arm/bin/arm-unknown-linux-gnu

The compiler (2.2.4) was running some minutes.
But no ppcarm there afterwards.
Any hint???

i know that this is not a new question , but all answers in the last 4 years seem to be a little bit different....

Or is there a running precompiled package anywhere or a rpm (oh yeah i know i am a softiii...)

Mit freundlichen Grüßen

Markus Greim

If you haven't done a "make install", then the compiler should be in ./compiler/.

Henry

And it will be called ppcrossarm (because it's a cross-compiler, rather than a native compiler).

To make it clear: the above command will create a non-EABI ARM little endian compiler, using the FPA floating point unit. If you want to use softfloat, add OPT="-Cfsoft". Moreover, if you (the original poster) intend to target an ARM-EABI platform, I would strongly recommend to use FPC 2.3.1 instead, because 2.2.4 contains quite a few bugs for those platforms. When using 2.2.x, at the very least you also have to add -O- to the OPT parameters.

Hallo Henry,

so thanks i am some steps further

i now installed the arm binutils from the Suse distribution ist version 2.19 instead of 2.16 and installed in

/opt/cross/arm-linux/bin/

by Yast

So i now mad a call:

make all CPU_TARGET=arm OS_TARGET=linux
BINUTILSPREFIX=/opt/cross/arm-linux/bin/

an voila it compiles... and ppcrossarm was in ./compiler fantastic.

Then i did a

make install CPU_TARGET=arm OS_TARGET=linux
BINUTILSPREFIX=/opt/cross/arm-linux/bin/

and now there are some files in
/usr/bin

looks fine!

But now i did a
ppcrossarm -B hallo.pas

The compiler seems to run, and making the s-file, but assembling the s-file failed, with more then 20 error messages. like

makuslinux3:/home/markus/arm # ppcrossarm -B -Aas hallo.pas Free Pascal Compiler version 2.3.1 [2009/07/21] for arm Copyright (c) 1993-2009 by Florian Klaempfl

The compiler is calling your i386/x86_64 assembler instead of the ARM one. I guess /opt/cross/arm-linux/bin/ is not in your path.

Jonas

2009/7/21 greim :

Using the wrong assembler? Make sure your arm assembler and linker is on the path.

Henry

When I build the compiler i use this

--------- Linux ----------------
#!/bin/sh
export PATH=$PATH:/pp/bin
export PATH=$PATH:/Fpc/ArmBin/218
make clean all OS_TARGET=linux CPU_TARGET=arm PP=/pp/bin/fpc BINUTILSPREFIX=arm-linux-

--------Windows ----------------------------
PATH = c:\fpc\2.2.2\bin\i386-win32;c:\pp\bin\Arm
make clean all OS_TARGET=linux CPU_TARGET=arm BINUTILSPREFIX=arm-linux-

This works fine with the 222 and 223 version

Regards

Carsten

Hello Carsten et. al.

thanks for your help. I think i am to stupid to set the right paths and links. Maybe Suse is a little bit strange here.

Finally i copied the file Carsten has provided
at
http://www.freepascal.dk/
and it compiles...
My first Hello World on the ARM is also ok.

Thanks a lot

Markus Greim
