Hi, I'm new to stunnel and I'd like to compile it to ARM and x86 platforms. I downloaded the stunnel-5.17 package and I'm using the build-android.sh and android-ndk-r10e script to compile it: ../../configure --with-sysroot=/home/ptofanelli/android-ndk-r10e/platforms/android-18/arch-arm/ --build=i686-pc-linux-gnu --host=arm-linux-androideabi --prefix=/data/local I'm getting the message "The C compiler cannot create executables" and checking the logs I've found that the problem is this: configure:3538: arm-linux-androideabi-gcc conftest.c >&5 /home/ptofanelli/android-ndk-r10e/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.8/../../../../arm-linux-androideabi/bin/ld: error: cannot open crtbegin_dynamic.o: No such file or directory /home/ptofanelli/android-ndk-r10e/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.8/../../../../arm-linux-androideabi/bin/ld: error: cannot open crtend_android.o: No such file or directory /home/ptofanelli/android-ndk-r10e/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.8/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lc /home/ptofanelli/android-ndk-r10e/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.8/../../../../arm-linux-androideabi/bin/ld: error: cannot find -ldl collect2: error: ld returned 1 exit status I searched for this problem and a topic in stackoverflow ( http://stackoverflow.com/questions/16795583/android-error-cannot-open-crtbeg...) is said that the problem is the sysroot, so I tried to use the option --with-sysroot, but I'm getting the same problem. Can you help me? Thanks and regards, Pio Tofanelli
