Thanks Jonathan. I was aware that Boehm was broken, and so I added --with-sgen=yes and --disable-boehm as noted (though it looks like the configure line in my email was missing the options - sorry for the confusion).
I've also tried adding --with-gc=none instead of --disable-boehm, and in addition to --disable-boehm, and a few combinations of the three options. I've even thrown in --with-moon-gc=sgen: note the following differences between these attempts and my earlier email: - replaced --host and --target with armv7-a-linux-androideabi. Previously I was using armv5-linux-androideabi - Changed CFLAGS and CXXFLAGS to "-DARM_FPU_VFP". Previously I was using "-DARM_FPU_NONE=1" - hard coded "i686-pc-linux-gnu" for --build. Previously I was using --build=`config.guess` which gave a "command config.guess not found" error. I ran ./config.guess manually and inserted the value into the options. -- Original, successful build config for mono branch mono-2-10-8: ./autogen.sh --build="i686-pc-linux-gnu" --host=armv7-a-linux-androideabi --target=armv7-a-linux-androideabi --enable-nls=no --with-mcs-docs=no --with-mcs-build=no --with-moonlight=no --with-gc=none CFLAGS="-DARM_FPU_VFP=1" CXXFLAGS="-DARM_FPU_VFP" This builds successfully.
