Today I found some time to research since when excactly arm-embedded does not compile anymore, I found that since revision 23325 compile does not work anymore, can anybody help, it seems that the problem itself is hidden somewhere else in code...

Fixed in r23452.

Thank you very much Florian, this problem is now indeed fixed. I have encountered another one:

/Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s: Assembler messages: /Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s:20800: Error: thumb conditional instruction should be in IT block -- `bxeq r14' /Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s:20803: Error: thumb conditional instruction should be in IT block -- `subls r1,r1,#32' /Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s:20804: Error: thumb conditional instruction should be in IT block -- `strbls r1,[r12]' /Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s:20820: Error: thumb conditional instruction should be in IT block -- `bxeq r14' /Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s:20823: Error: thumb conditional instruction should be in IT block -- `addls r1,r1,#32' /Users/ring/devel/fpc/rtl/units/arm-embedded/sysutils.s:20824: Error: thumb conditional instruction should be in IT block -- `strbls r1,[r12]'

this one can be solved by adding -mimplicit-it=thumb to the the commandline of arm-embedded-as. I have created a replacement script for arm-embedded-as:

#!/bin/sh
/usr/local/bin/arm-embedded-as -mimplicit-it=thumb $*

with this script I can build latest svn.

What I do not understand is that this problem only exists when sysutils gets compiled, the svn code from 2012-01-04 works fine, the code from the next day shows this error, the 'only' change is that sysutils gets included in the build.

For now, how can I add "-mimplicit-it=thumb" to the as commandline without my small hack? can I put this somewhere in fpc.cfg?

Could you write the complete command line you use for compiling?

The command uses for building is straight from the wiki:

make clean buildbase installbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm SUBARCH=armv7m

without my small hack the build breaks, when I add:

export PATH=/Users/ring:$PATH

and put the small replacement script to /Users/ring the build finishes.

I am using GNU assembler version 2.23.1 (arm-none-eabi) using BFD version (GNU Binutils) 2.23.1

built from latest binutils sources, commands also taken from Target Embedded Wiki
