Hi,
Since a while I'm experiencing problems compiling fpc from svn for arm-linux. When "make CPU_TARGET=arm OS_TARGET=linux all" arrives at assembling system.pp for arm it gives following errors : /home/koenraad/fpc-devel/fpc/compiler/ppcrossarm -Ur -XParm-linux- -Xc -Xr -Ur -Xs -n -Fi../inc -Fi../arm -Fi../unix -Fiarm -FE. -FU/home/koenraad/fpc-devel/fpc/rtl/units/arm-linux -darm -dRELEASE -Us -Sg system.pp
/home/koenraad/fpc-devel/fpc/rtl/units/arm-linux/system.s: Assembler messages:
/home/koenraad/fpc-devel/fpc/rtl/units/arm-linux/system.s:51628: Error: unrecognized symbol type ""
/home/koenraad/fpc-devel/fpc/rtl/units/arm-linux/system.s:51636: Error: unrecognized symbol type ""
/home/koenraad/fpc-devel/fpc/rtl/units/arm-linux/system.s:51643: Error: unrecognized symbol type ""
...(about 40 similar lines)
When I look in system.s at those lines they are all similar to : .section .bss
.balign 2
.globl operatingsystem_result
.type operatingsystem_result,@object
.size operatingsystem_result,2
operatingsystem_result:
.zero 2
More specific, the error-lines point to the @object construct. Is there any way I can avoid these errors ?
I used revision 2898 of fpc. My arm-linux-as is version 2.14. Thanks for any help,
Koenraad Lelong.

Use the latest binutils 2.16.1

I downloaded and compiled them from http://www.gnuarm.com, then compiled fpc with it, with no success. Tried again from www.gnu.org, same result. Do I have to specify some option ?

This program is buggy - '@' is used as the comment character for ARM, so everything after that is ignored. The assembler therefore sees:
.type operatingsystem_result,
which is garbage. The GNU assembler targetted for ARM accepts '#' or '%' here, not '@'.

Is there anyone who can give a hint where to look to fix this ? Regards,

Remove "tf_needs_symbol_type" from system_arm_linux_info in compiler/ systems/i_linux.pas
Or alternatively have a look at the output of gcc -S and if it does generate some sort of symbol type information, change compiler/ aggas.pas:590 based on "if (target_info.system system_arm_linux) then ... else ..."

Thanks,
Enclosed you will find a diff that allows me to get past that error, but I have another one. Actually two, this morning I had an 'internal error', but I (stupidly) did another svn-update and now I'm having an offset too large in sysutils :

I got past this error by modifying sysstr.inc (see the enclosed diff). I hope it's an acceptable patch.
Now I'm having internal error 200203271 when compiling buildgtk2.pp/gtkspinbutton.inc. I'm going to ,

No ;) It solves the problem but not the cause :) I'll look into it when I find time ;)

I don't know if it's usefull : those lfm and sfm instructions seem to be limited to 10 bit offsets (max 1024, 4byte boundary, found by trail and error).
I didn't find much information in arm-docs about those floating point register instructions.
