I'm trying to compile a static library for the opencore-amr project to use in ios. My setup is Xcode4.2 / iOS5 sdk (since I'm still running Snow Leopard). I've tweaked the build script attached here to use -isysroot instead of --sysroot, and updated the SDK var to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk
This fails in the config checks at this point:
checking how to run the C preprocessor... /lib/cpp
configure: error: in `/Users/ldwong/Documents/xcode/opencore-amr-0.1.3':
configure: error: C preprocessor "/lib/cpp" fails sanity check
according to my config.log, the first failure during this check is in finding limits.h:
configure:7965: checking how to run the C preprocessor
configure:7996: gcc -arch armv6 -isysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -E conftest.c
In file included from conftest.c:12:
/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/../lib/gcc/arm-apple-darwin10/4.2.1/include/limits.h:15:25: error: no include path in which to search for limits.h
configure:7996: $? = 1
configure: failed program was:
...
and farther down it also fails to find assert.h with this command:
configure:7996: gcc -arch armv6 -isysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk -E -traditional-cpp conftest.c
conftest.c:14: error: assert.h: No such file or directory
Can anyone point out what I'm missing or doing wrong? Thanks!
