Re: [fpc-devel] Second version of FPC for iPhone SDK 2.x available
hello Jonas, what do you think about using another fpc.cfg file (i.e. fpcxcode.cfg) for iPhone compilation, rather than passing compiler configuration through the command line? i guess that the ideally, there would be no additional .cfg files, and compiler should use common configuration. But for now, an additional .cfg file would make compiler configuration easier! Also, i'm not experienced in compiling fp-cross-compilers, but is it possile to build ppcarm (for darwin) from svn trunk?

[fpc-devel] Porting FPC to Support OpenMoko
Hello, I have a real (not emulator) opnmoko PDA/cell phone. The main distro for it uses armv4tl. Is there a need to add extra support for OM, or will FPC (what version) will support it ? If there is a support, are there any known issues with it ? If there is work needed to be done, can you please point me to what is needed to be done ? Thanks, Ido ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

configuration easier!
No, because it's not enough that the compile can find its units. Xcode
can transparently link together C, C++, Objective-C and Pascal code,
but for this it needs to know all the necessary libraries and object
files. For this reason, the template generates a static library
containing the object files of all units shipped with FPC and tells
Xcode to link this library (it will only link the object files of the
actually used units).
It would be hard to get everything smoothly running if custom fpc.cfg
files were supported for a variety of reasons (no guaranteed order in
which script phases are executed in Xcode, no guaranteed common
directory to use by different targets). What would however be
possible, is to allow easily changing the location of the used
*installed* copy of FPC (so you don't have to install under /usr/
local, but anywhere you want). This requires some changes to the
template though.
Also, i'm not experienced in compiling fp-cross-compilers, but is it
possile to build ppcarm (for darwin) from svn trunk?
1) copy /Developer/FreePascalCompiler/iPhoneSnapshot-2.3.1-r12531/
Source/rtl/darwin/arm/sig_cpu.inc to the rtl/darwin/arm directory of
your svn checkout (that file was generated when you installed the FPC
iPhone SDK integration kit)
2) in the top level fpc directory of your checkout, execute the
following (in the first line, replace /iphone2.1 with the name of
the actual directory where you installed the iPhone SDK):
export IPHONEPLATFORMBASEDIR=/iphone2.1/Platforms/iPhoneOS.platform/
Developer
make FPC=your_ppc386_2.3.1 CPU_TARGET=arm CROSSOPT=-FD$
{IPHONEPLATFORMBASEDIR}/usr/bin -XR${IPHONEPLATFORMBASEDIR}/SDKs/
iPhoneOS2.0.sdk/ -ap all

In trunk/r12933 you can now force the compiler to always store
absolute path for include files using -gostabsabsincludes. See the
svn comment for why it's not the default (gcc also never does this,
you can't even force it to do that). There is no way to specify a
separate base directory for an include file in stabs, as opposed to
for the main source file.
The reason that gdb previously already found an absolute path for
some include files, was probably that they were located in the same
directory as the main unit file.
Sorry, for me it is somehow strange that this works different:
{file=C:/programming/fpc/rtl/i386/i386.inc,fullname=C:/
programming/fpc/rtl/i386/i386.inc} and
{file=./include/messagedialogs.inc}
main unit file is located in
C:/programming/mytest/0.9.27/SafeCall/project1.lpr
Did you recompile everything with -gostabsabsincludes? And did it
change anything at all?

No, I had not. I'm asking about default fpc behavior. I just found it
strange that 2 files are handled different while both have .inc extension.

They are not necessarily handled differently. When gdb finds an
include file specified in the debug information, then it will always
display the full path in the output above. If it doesn't find it (for
whatever reason), it will display what's stored in the debug
information (which can be a relative path).

FreePascal is only precompiled for the first configuration? i think so. even debian lenny uses eabi now, so this will probably change. Thanks in advance for any advice.
