Hi All, I'm trying to cross compile libxml2 (http://www.xmlsoft.org/downloads.html) for Android. libxml2 use autotools. I have a script the detects the Android NDK gear and sets the environment, path, CPP, CC, CXX, AS, AR, LD, SYSROOT, etc. It works great for projects such as Botan, Crypto++, Cryptlib, OpenSSL, libcurl, etc. For example: $ echo $CPP arm-linux-androideabi-cpp $ echo $CC arm-linux-androideabi-gcc $ echo $ANDROID_NDK_ROOT /opt/android-ndk-r9 $ echo $ANDROID_SYSROOT /opt/android-ndk-r9/platforms/android-14/arch-arm $ echo $CFLAGS --sysroot=/opt/android-ndk-r9/platforms/android-14/arch-arm $ echo $PATH /opt/android-ndk-r9/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86_64/bin: /opt/android-sdk-macosx/tools/:/opt/android-sdk-macosx/platform-tools/: /opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin: /opt/X11/bin:/usr/local/MacGPG2/bin .. Building libxml2 is having some trouble. When I try to configure: $ ./configure --host=arm --build=arm --with-sysroot=$ANDROID_SYSROOT checking build system type... arm-unknown-none checking host system type... arm-unknown-none checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... ./install-sh -c -d checking for gawk... no checking for mawk... no checking for nawk... no checking for awk... awk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking for arm-gcc... arm-linux-androideabi-gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... configure: error: in `/Users/jwalton/libxml2-2.9.1': configure: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details When I check the log: $ cat config.log ... configure:3612: checking whether we are cross compiling configure:3620: arm-linux-androideabi-gcc -o conftest --sysroot=/opt/android-ndk-r9/platforms/android-14/arch-arm conftest.c >&5 configure:3624: $? = 0 configure:3631: ./conftest ./configure: line 3633: ./conftest: cannot execute binary file configure:3635: $? = 126 configure:3642: error: in `/Users/jwalton/libxml2-2.9.1': configure:3644: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details I'm not sure why I'm trying to trick the build system with host=arm since the host is x86_64. And it feels like I am not specifying the target properly, but `configure --help` does not list any target configuration options. Even with a `--host=arm`, configure is telling me to specify a cross compile with `--host`. I feel like I'm taking stabs in the dark with libxml2. Google is not being very helpful because the leading dash (i.e., --host) means the term should be excluded from the search terms. Would someone be kind and tell me precisely what I should be supplying to `config`?
