cross-compile libiconv-1.14 on MacOS10.7,I will introduce step by step:

⑴：download source code (http://ftp.gnu.org/pub/gnu/libiconv/)

⑵：execute build command

./configure --prefix=/Users/jwang/libiconv --host=arm-apple-darwin --enable-static=yes --enable-shared=no CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc CFLAGS="-arch
armv6 -pipe -mdynamic-no-pic -Wno-trigraphs -fpascal-strings -O0 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=2.0 -gdwarf-2 -mthumb -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/include/libxml2
-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk" CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk
-Wl,-dead_strip -miphoneos-version-min=2.0" LD=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ld--disable-cxx

if you meet with this problem:

unistd.h:668:28: error: crt_externs.h: No such file or directory

you can execute:

cp /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/include/crt_externs.h

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/include/

⑶：execute make and make install all right
