Summary: Autoconf errors when checking for several headers
Description:
When cross-compiling for ARM, configure fails to recognize several headers with
the "Header Present But Cannot Be Compiled" issue
(http://www.gnu.org/software/autoconf/manual/autoconf-2.67/html_node/Present-But-Cannot-Be-Compiled.html).
It seems this can be fixed by adjusting configure.ac, but I'm not an expert with
autoconf at all. I'll append the cross-compile setup and the full output on the
affected headers, which are:
- errno.h
- stddef.h
- getopt.h
- regex.h
- sys/time.h
- time.h
- math.h
- limits.h
- libxml/xmlschemas.h
- libxml/xmlschemastypes.h
- libxml/schemasInternals.h
Sidenote: raptor does cross-compile fine with the attached setup
Steps to Reproduce:
- Install Xcode 4.4+ on OS X
- From within Xcode, run "Install Command Line Utilities"
- install pgk-config if you haven't already
- Download rasqal's source, unpack and cd into it
- run the following script (which will run ./configure):
#!/bin/bash
#
# This script runs the GNU Autotools created "./configure" script in order to
# cross compile C libraries for iOS.
#
# Easiest is to place this script in your $PATH, e.g. /usr/local/bin, and run
# "ios-configure" instead of "./configure". Afterwards, just run "make" and
# "sudo make install". By default, the libraries will be installed into
# "/usr/local/ios-x.x"
#
# This script has last been tested with Xcode 4.5-DP2 on OS X 10.8
