FYI, autoconf is not supplied by Xcode 5 (or 4.5); it has to be installed, such as I have done with MacPorts:
$ xcrun --find autoconf /opt/local/bin/autoconf $autoconf --version autoconf (GNU Autoconf) 2.69 I tried this: $ autoconf -W all configure.ac:95: warning: The macro `AC_PROG_LIBTOOL' is obsolete. configure.ac:95: You should run autoupdate. aclocal.m4:129: AC_PROG_LIBTOOL is expanded from... configure.ac:95: the top level configure.ac:107: warning: The macro `AC_CHECK_LIBM' is obsolete. configure.ac:107: You should run autoupdate. aclocal.m4:3593: AC_CHECK_LIBM is expanded from... configure.ac:107: the top level I did as I was told: $ autoupdate $ autoconf -W all I then reran configure, and the error from __arm__ being undefined is gone, but the Syntax error problem is still there. I had previously established that running ./configure with no options succeeded; I ran it again having defined CC and CPP to clang: > configure:3060: checking build system type > configure:3074: result: x86_64-apple-darwin13.0.2 > configure:3094: checking host system type > configure:3107: result: x86_64-apple-darwin13.0.2 > configure:3182: checking for gcc > configure:3209: result: > /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang > configure:3438: checking for C compiler version > configure:3447: > /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang > --version >&5 > Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn) > Target: x86_64-apple-darwin13.0.2 > configure:4119: checking how to run the C preprocessor > configure:4150: > /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang > -E conftest.c This works. So maybe it’s not clang per se, but something it’s being fed. All very confusing. Still waiting for insight.
