Hi, Have you see this issue before? plz help me go forward.. I'm in trouble to getting start build on PJSIP for Android on Cygwin(Win7). could't complete "checking whether the C compiler works" in './configure-android' I'v verified Android NDK already and Environment variables as below before run 'configure-android' TARGET_ABI=armeabi APP_PLATFORM=android-8 There is 'libc.so' and 'libgcc.so' in linker search directory correctly. I have a suspicion that linker was picked as 'AndroidNDK\android-ndk-r8e\toolchains\arm-linux-androideabi-4.4.3\prebuilt\windows-x86_64\arm-linux-androideabi\bin\ld.exe' instead of 'AndroidNDK/android-ndk-r8e/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows-x86_64/bin/arm-linux-androideabi-ld' $ ./configure-android configure-android: calling ./configure with env vars: CC = /cygdrive/d/SW/Development/AndroidNDK/android-ndk-r8e/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows-x86_64/bin/arm-linux-androideabi-gcc CXX = /cygdrive/d/SW/Development/AndroidNDK/android-ndk-r8e/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows-x86_64/bin/arm-linux-androideabi-g++ CFLAGS = -I/cygdrive/d/SW/Development/AndroidNDK/android-ndk-r8e/platforms/android-8/arch-arm/usr/include CXXFLAGS = -shared --sysroot=/cygdrive/d/SW/Development/AndroidNDK/android-ndk-r8e/platforms/android-8/arch-arm LDFLAGS = -nostdlib -L/cygdrive/d/SW/Development/AndroidNDK/android-ndk-r8e/platforms/android-8/arch-arm/usr/lib/ LIBS = -lc -lgcc checking build system type... i686-pc-cygwin checking host system type... arm-unknown-linux-androideabi checking target system type... arm-unknown-linux-androideabi checking for arm-linux-androideabi-gcc... /cygdrive/d/SW/Development/AndroidNDK/android-ndk-r8e/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows-x86_64/bin/arm-linux-androideabi-gcc checking whether the C compiler works... no aconfigure: error: in `/cygdrive/d/Projects/FanLing/SIP/PJSIP/android-target': aconfigure: error: C compiler cannot create executables See `config.log' for more details == config.log == This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.
