Thank you, Martin, for your knowledgeable explanation. I was able to
determine that the ARM Apple uses has a VFP co-processor, so I did a little
more testing and eventually found out that... I was using the wrong version
of GCC to build it! Apple included two versions of GCC for cross-compiling
to ARM, and I used the wrong one.
Unfortunately, I am still having problems. I believe I am getting through
the configuration process without any warnings (at least when I compile
without GMP). There are new problems in what appears to be the lisp phase of
the build.
My configuration instruction:
#!/bin/sh
./configure \
--prefix=/Users/red/lib/iphoneos-ecl/ \
--host=arm-apple-darwin \
--without-gmp \
--disable-shared \
CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.0 \
AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar \
CFLAGS="-arch armv6 -pipe -std=c99 -Wno-trigraphs -fpascal-strings
-fasm-blocks -O0 -Wreturn-type -Wunused-variable -fmessage-length=0
-fvisibility=hidden -miphoneos-version-min=2.0 -gdwarf-2 -mthumb -miphon\

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk" \
CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp
The build appears to abort to the top-level

>From what I can tell, one problem is that not all the GCC flags I specified
in the configuration stage are preserved in this latter stage of the build.
The command issued at the end of the final output,
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.0 -o
"/Users/red/Projects/ecl/ecl-iphone/build/bin/ecl"
-L"/Users/red/Projects/ecl/ecl-iphone/build/"

"-lsockets" "-lprofile" "-lcmp" "-L./" libecl.a -leclgc -lm
does not contain the -arch arm etc. flags specified in my call to
configure. However, many other calls to gcc do have those flags.
The AR value I specify also does not make it all the way to the lisp stage.
Commands like " ar cr libsockets.a ..." are being called instead of
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar. I'm not sure
what difference this makes.
I will keep hacking away at this but your expert opinions would be helpful!
I avoid C as much as I can, so this is a different world.
Thanks,
Red
