TOPIC:

Finally i done, i can run graphical pascal binaries in a TAblet PengPod 1.2ghz Cortex A8 ARM Core.

this is the hardware:
www.androidpit.com/pengpod-the-true-linux-tablet

the result is awesome, litteraly fly's:
1.- in fact in can comunication with serial port reseeving serial data at 38400 bps, without problems, using spdo
2.- i can graphs in real time
3.- i can use mysql connection without problems
pd: the only problem, is you need to set up fontsize to 0 (label, button's, panels), otherwise dissapears

let'me advices to other people that the wiki tutorial 'CRoss-compile for ARM', wasn't work, only work if you want simple text application's, and why don't work?, i ' m not cross compile expert , but don't work because:
BEFORE you have FPC working

1.-Is necessary rebuild gcc
2.-Is necessary rebuild gdb
3.- Is necesary Newlib (rebuild too)
4.- rebuild binutils
5.- you need import lib's from the tablet, (/lib/ & /usr/lib/), in a directory on the host like 'licross125'
6.- you need to change some file names like: pango-1.2.so.000.1 -> pango-1.2.so (the compiler tell you the names)

the used parameter is differnt is=arm-elf

thank's to a german wiki tutorial, i can create the correct ToolChain:
the tutorial is:

(you need fpc running good before)

wiki.ubuntuusers.de/GNU_ARM-Toolchain

the results are truly nice

regards

Congratulations, Trazanet!

I think many of us also want to get a GUI app running on ARM-Linux but haven't be successful yet. Currently, I also got stuck at "arm-linux-ld.exe: cannot find -ldl".

I'm new to this cross-compiling so I'd appreciate it if you can give us more details. Can you confirm if the necessary steps are:
1. Have CT installed on a host PC running Linux. Choose to build the cross-compile toolchain with ARM and LIUNX.
2. Follow the German page you pointed us to build the "GNU ARM toolchain" i.e. the steps 1-4 listed in your last message (install GCC, GDB, Newlib and Binutils).
3. Do the final steps 5 and 6 in your last message.

And then going back to CT, we would then be able to cross-compile to ARM-Linux (with Target OS=Linux and Target CPU=ARM, and "Generate debugging info..." unchecked, like said in the wiki)?

Thank you!

hi.

Yes!, you need rebuild many thing's. I do it with Lazarus.
is necessary rebuild newlibs, gcc, binutils, gdb (is neccesary rebuild a toolchain). is better use a virtual machine with ubuntu.
my enviorment:
ubuntu 12.04 (all updates ok)
fpc-2.6.2
fpc-source-2.6.2
lazarus 1.0.8

1.- follow the german wiki, one is done do it this (prev. lines is from other post):

"After all it creates a structure in /opt/gnuarm which can be used to compile Hello-World. I was missing at least libgl and did not find a way to build it. So one can access different precompiled toolchains as well (www.gnuarm.com/, www.yagarto.de/, www.codesourcery.com/). I downloaded this file decompressed it to /opt (arm-2009q3) and applied that path to all further steps.

5. fpc

make distclean
make crosszipinstall CPU_TARGET=arm OS_TARGET=linux OPT="-dFPC_ARMEL" CROSSOPT="-XR/opt/arm-2009q3/arm-none-linux-gnueabi -dFPC_ARMEL -CfSOFT -Cparmv5" FPC=/usr/local/lib/fpc/2.5.1/ppcx64


- crosszipinstall to create but not install
- -XR<> root dir where as and ld can be found
- ppcx64 is the compiler on 64bit systems, for 32bit it is called ppc386

It results in a packed file like fpc-2.5.1.arm-linux.tar.gz just where the makefile resides. Unpack the content to /usr/local/lib/fpc... and create a link for ppcrossarm into /usr/local/bin. Now ppcrossarm can be used to compile sources
6. Compilation
ppcrossarm -Xd -Fl/opt/arm-2009q3/arm-none-linux-gnueabi/libc/usr/lib -CaEABI -Parm -CfSOFT -CpARMV5 Example.pas


-Xd don't use standard lib path
-Fl use directory to search for libs
I don't know if it works without -C options.
"

pd: if you find the way to rebuild the toolchain with codetyphon, let me know


and that's it!!.

Hello all.

This is a little demostration of succesfulll cross-compile SCADA Software Running on a TableT PENGPOD.

Properties
1.- Receiving data al 38400 bps
2.- Graphs in real time
3.- And all advantages of a GNU/Linux Platform

This is really encouraging!
