The following issue has been SUBMITTED. ====================================================================== http://bugs.librdf.org/mantis/view.php?id=517 ====================================================================== Reported By: Pascal Assigned To: ====================================================================== Project: Rasqal RDF Query Library Issue ID: 517 Category: configuration Reproducibility: always Severity: minor Priority: normal Status: new Query Language: ====================================================================== Date Submitted: 2012-07-18 16:05 Last Modified: 2012-07-18 16:05 ====================================================================== 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 $PATH, e.g. /usr/local/bin, and run # "ios-configure" instead of "./configure". Afterwards, just run "make" and # "sudo make install". By default, the libraries will be installed into # "/usr/local/ios-x.x" # # This script has last been tested with Xcode 4.5-DP2 on OS X 10.8 # export SDKVER="6.0" export PREFIX="/usr/local/ios-$SDKVER" #ARMV6="-arch armv6" ARMV7="-arch armv7" # clean up unset CPATH unset C_INCLUDE_PATH unset CPLUS_INCLUDE_PATH unset OBJC_INCLUDE_PATH unset LIBS unset DYLD_FALLBACK_LIBRARY_PATH unset DYLD_FALLBACK_FRAMEWORK_PATH # determine SDK-root export BUILD_DARWIN_VER=`uname -r` export XCODE="$(xcode-select --print-path)" export DEVROOT="$XCODE/Platforms/iPhoneOS.platform/Developer" if [ ! -d "$DEVROOT" ]; then echo "There is no iOS SDK at \"$DEVROOT\"" exit 1 fi export SDKROOT="$DEVROOT/SDKs/iPhoneOS$SDKVER.sdk" if [ ! -d "$SDKROOT" ] ; then echo "The iPhone SDK could not be found.
