Hi,

How do I reference a image uploaded in one language (english), but in a another language (french, german) page?

The same problem applies for the Lazarus pages on Wikipedia. I uploaded a new screenshot of Lazarus 0.9.25 on the english page, but don't know how to update the other Lazarus language pages with that same screenshot.

Regards,
- Graeme -

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.

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,

Thanks for the suggestions. Will try cross compiling. I cross compile using "/home/nataraj/arm-2008q1/arm-none-linux-gnueabi-".

Freepascal wiki says to install fpc for the native x86 machine first. Then go for fpc-arm version 2.0.4. Which version of fpc should i install in native host - 2.2.0 or 2.0.4? Also, for cross compiling 2.0.4 ,how do i specify the said cross bin utils ?

regards

Nataraj

i use trunk to cross compile for arm, but i think fixes_2_2 will also work. you should use 2.2.0 as a starting compiler (but 2.0.4) also works for me.

you have to tell the build system where your binutils are (BINUTILSDIR=/home/nataraj/arm-2008q1/) and what prefix you use (BINUTILSPREFIX=arm-none-linux-gnueabi-). then you need to use CROSSOPT="-CfSOFT" for the softfloat business.

all the packages get built for me, it just dies near the end of make crossinstall.

the buildfaq contains good info (thanks to marco): www.stack.nl/~marcov/buildfaq.pdf

Hi Henry Please give me the exact command used by you for compiling.

here's a script. change the params as you need.

What does the crossinstall target do? (I mean, differently than plain install)

Bye

Hi Henry

Please give me the exact command used by you for compiling.

Hi Henry

Thank you. Trying it out.

Compilation getting aborted telling

make[5]: Entering directory `/home/kodi/fpc/rtl/linux' /bin/mkdir -p /home/kodi/fpc/rtl/units/arm-linux
/home/nataraj/arm-2008pq1/arm-none-linux-gnueabi/bin/as -o /home/kodi/fpc/rtl/units/arm-linux/prt0.o arm/prt0.as make[5]: /home/nataraj/arm-2008pq1/arm-none-linux-gnueabi/bin/as: Command not found make[5]: *** [prt0.o] Error 127

But path for assembler is correct.

It build the ppcrossarm in fpc/compiler. I am able to compile a program with it after symlinking the above assembler and linker to /usr/local/bin/arm-linux-as and arm-linux-ld respectively. Lots of warning are generated.

But when I copied the binary to Target linux, the execution just hangs wihtout output till I CTRL-C.

"home/nataraj/arm-2008pq1/arm-none-linux-gnueabi/bin/" is bin utils from Sourcery that is used to compile kernel 2.6.25 for ARM board.

What else should I do?

Hi

I get the following strace out put when executing a fpc cross compiled binary using ppcrossarm (generated from latest fpc svn using following script :-

My ARM Linux kernel is on Atmel AT91SAM9263 is
Linux at91sam9263ek 2.6.25 #34 Sat Jun 7 20:02:51 IST 2008 armv5tejl unknown

I use bin utils from CodeSourcery for cross compiling EABI kernel as well as fpc.
The kernel is compiled with

CONFIG_AEBI=y
CONFIG_ARM_THUMB=y

But I am not able to enable OABI_COMPAT=y.

Why dont my binary work on the Arm board? What else is to be done?
