Re: [fpc-pascal] fpc 2.6.0 for arm-embedded
I do have a working crosscompiler (I think), only I have to call it via /usr/lib/fpc/2.6.0/ppcrossarm ..., instead of via fpc ... The code seems not to work, but that could be my own RTL, which I copied from SMT32F103RE. I'm working on that. After some debugging, I think my compiler does not work. I'm pretty certain it outputs arm-code in stead of the needed thumb2 code. I just tried to make a crosscompiler using svn 20278, which fails : make rtl_all FPC=/home/koenraad/devel/fpc-svn/compiler/ppcrossarm RELEASE=1 make[1]: Map '/home/koenraad/devel/fpc-svn' wordt binnengegaan make -C rtl all make[2]: Map '/home/koenraad/devel/fpc-svn/rtl' wordt binnengegaan make -C embedded all make[3]: Map '/home/koenraad/devel/fpc-svn/rtl/embedded' wordt binnengegaan /bin/mkdir -p /home/koenraad/devel/fpc-svn/rtl/units/arm-embedded /home/koenraad/devel/fpc-svn/compiler/ppcrossarm -Cparmv7m @rtl.cfg -Ur -Tembedded -Parm -XParm-none-eabi- -Xr -Ur -Xs -O2 -n -Fi../inc -Fi../arm -FD/home/koenraad/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_EABI/bin -FE. -FU/home/koenraad/devel/fpc-svn/rtl/units/arm-embedded -darm -dRELEASE -CfSoft -Us -Sg system.pp text.inc(1897,3) Fatal: Unknown compilerproc fpc_ansistr_assign.

What I say above is from a crosscompiler made with 2.6.0. Below is what I get when I try to make a new crosscompiler, using svn 20278.

That's what I think I did. I had fpc 2.6.0 installed. I downloaded fpc trunk via svn. In the root of the download I did make clean build install (as root). I renamed /usr/lib64/fpc/2.6.0 to -2.6.0- so it would not be found. I renamed /usr/bin/ppcx64 to ppcx64-2.6.0. I made a link from /usr/lib/fpc/2.7.0/ppcx64 to /usr/bin/ppcx64. I modified /etc/fpc.cfg to use /usr/lib/fpc/2.7.0... fpc -i shows 2.7.1 In the root of the download I tried to make the crosscompiler and then I got the error. Is there a way to verify there are no files left ? I tried fpc -vt but that seems not the tool.

Strange. Last time I downloaded Paul's Windows archive he released, it was indeed a cross-compiler for x86 (32-bit) to ARM (and not a native arm executable). I could then compile my mobile application under Windows 2000, then copy my compiled application to my ARM / WinCE based PDA and run in there.

Re: [fpc-pascal] fpc 2.6.0 for arm-embedded
Hi, I just had some time to look into this again. I downloaded the latest 2.6.0 sources and mostly followed http://wiki.freepascal.org/TARGET_Embedded to make a crosscompiler. In /usr/lib/fpc/2.6.0 there is a ppcrossarm with a date of today when I run ppcrossarm -i. But when I try fpc -Parm -Tembedded -Wplpc2124 -Cparmv7m I get an error : Error: ppcarm can't be executed, error message: Failed to execute ppcarm, error code: 127 Is this expexted ? If yes, then the wiki should be updated. If it matters, I'm using OpesSuse 12.1. Another thing that puzzles me : the wiki says to use SUBARCH=armv7m for cortex-m3. ppcrossarm -i says there are cpu instruction sets for ARMV3 ARMV4 ARMV5 ARMV6 ARMV7 ARMV7M CORTEXM3 Should I use SUBARCH=cortexm3 to compile the compiler to use it with STM32-processors, which are cortex-m3 ? Or should I just compile the applications with -Cpcortexm3 ? Thanks for any info.

Simply because arm-embedded is a much less used and tested branch, the functionality might be slower to get into releases.
