[pjsip] pjproject-1.5.5 cross compile to iPod -compile test -Passed and fix

[Woscek, Martin W.]

Just got back to setting up my environment and testing that.  Seemed to be a version thing between Leopard and Snow-Leopard. But the following were my steps just to get a test compile to succeed:

1.       I uninstalled the Snow-Leapard (iphone_sdk_3.1.3_with_xcode_3.2.1_snow_leopard__10m2003a.dmg) and deleted all directory tree left behind (/Developer).

2.       Next I installed the Leopard version (iphone_sdk_3.1.3_with_xcode_3.1.4_leopard__9m2809a.dmg).  ** Still cant compile!  Different errors but same basic result.

3.       Rather than uninstalling the Leopard version, I re-installed the Snow-Leopard on top and verified that  "upgrade" was selected where appropriate.  **Im now beyond the basic compile test:

pjproject-1.5.5-21Feb10$ arm-apple-darwin9-gcc-4.2.1  -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.sdk ./martin.c
ld: warning: -force_cpusubtype_ALL will become unsupported for ARM architectures

pjproject-1.5.5-21Feb10$ file a.outa.out: Mach-O executable arm
Ya Hoo!

Also required slight updates to the shell script listed in the  "Compilation" section of:

Subject: [pjsip] pjproject-1.5.5 cross compile to iPod -compile test fail

Hello all,

I am now moving onto the cross compiling to the iPod (because I have one temporarily until I get an iPhone) and am having problems with the basics env setup.
I have followed both links for the pjproject-1.5.5 cross compile:

http://code.google.com/p/siphon/wiki/CompilationForiPhoneOS2_X

http://www.piemontewireless.net/PJSip155_and_iPhoneSDK312

Using the linked compiler arm-apple-darwin9-gcc I fail the simple compile test during the configure run and receive:

ld: library not found for -lcrt1.o

The GNU gcc worked for my earlier cross-compile over to the iPaq.   This was modified/enhanced version based on pjproject-1.0.1 with no problems executing on the iPAQ running Angstrom's Linux:
./configure arm --host arm-linux -target xscale

export CFLAGS="-mcpu=xscale"

export LDFLAGS="-static -static-libgcc"
make dep;make

Shouldn't I be able to use gcc with the -mcpu options rather than the
arm-apple-darwin9-gcc  -> arm-apple-darwin9-gcc-4.2.1 ??

This is probably a MAC OS environment issue here....but any help is appreciated.
