arm-linux-androideabi-ld: , noexecstack: unknown -z option

[Sinhbk]

Hi,

When I am running build_android.sh, I got the issue:

arm-linux-androideabi-ld: , noexecstack: unknown -z option

I think the issue is taken by the below code with piece code -z,noexecstack

Anyone help or suggest me how to fix it?

Thanks!

function build_one { cd ffmpeg PLATFORM=$NDK/platforms/$PLATFORM_VERSION/arch-$ARCH/ $PREBUILT/bin/$EABIARCH-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib -soname $SONAME -shared -nostdlib -z,noexecstack -Bsymbolic --whole-archive --no-undefined -o $OUT_LIBRARY -lavcodec -lavformat -lavresample -lavutil -lswresample -lass -lfreetype -lfribidi -lswscale -lvo-aacenc -lvo-amrwbenc -lc -lm -lz -ldl -llog --warn-once --dynamic-linker=/system/bin/linker -zmuldefs $PREBUILT/lib/gcc/$EABIARCH/4.4.3/libgcc.a || exit 1 cd .. }

Thanks

I'm get this error too:

INSTALL libavcodec/libavcodec.a

I think the same of @Sinhbk , I go try with that code:

$PREBUILT/bin/$EABIARCH-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib  -soname $SONAME -shared -nostdlib  -z noexecstack -Bsymbolic --whole-archive --no-undefined -o $OUT_LIBRARY -lavcodec -lavformat -lavresample -lavutil -lswresample -lass -lfreetype -lfribidi -lswscale -lvo-aacenc -lvo-amrwbenc -lc -lm -lz -ldl -llog  --warn-once  --dynamic-linker=/system/bin/linker -zmuldefs $PREBUILT/lib/gcc/$EABIARCH/4.8/libgcc.a || exit 1

instead

$PREBUILT/bin/$EABIARCH-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib  -soname $SONAME -shared -nostdlib  -z,noexecstack -Bsymbolic --whole-archive --no-undefined -o $OUT_LIBRARY -lavcodec -lavformat -lavresample -lavutil -lswresample -lass -lfreetype -lfribidi -lswscale -lvo-aacenc -lvo-amrwbenc -lc -lm -lz -ldl -llog  --warn-once  --dynamic-linker=/system/bin/linker -zmuldefs $PREBUILT/lib/gcc/$EABIARCH/4.8/libgcc.a || exit 1

note the "-z noexecstack" instead "-z,noexecstack".

now with the code as follow, I'm getting the error:

$PREBUILT/bin/$EABIARCH-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib  -soname $SONAME -shared -nostdlib  -z noexecstack -Bsymbolic --whole-archive --no-undefined -o $OUT_LIBRARY -lavcodec -lavformat -lavresample -lavutil -lswresample -lass -lfreetype -lfribidi -lswscale -lvo-aacenc -lvo-amrwbenc -lc -lm -lz -ldl -llog  --warn-once  --dynamic-linker=/system/bin/linker -zmuldefs $PREBUILT/lib/gcc/$EABIARCH/4.8/libgcc.a || exit 1

/home/ademar/android-ndk-r9/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/arm-linux-androideabi-ld: use the --help option for usage information

So, looking to helper:

$ /home/ademar/android-ndk-r9/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/arm-linux-androideabi-ld --help | grep warn

I no see the option "--warn-once", i will try wothou it, like as follow:

$PREBUILT/bin/$EABIARCH-ld -rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -L$PREFIX/lib  -soname $SONAME -shared -nostdlib  -z noexecstack -Bsymbolic --whole-archive --no-undefined -o $OUT_LIBRARY -lavcodec -lavformat -lavresample -lavutil -lswresample -lass -lfreetype -lfribidi -lswscale -lvo-aacenc -lvo-amrwbenc -lc -lm -lz -ldl -llog --dynamic-linker=/system/bin/linker -zmuldefs $PREBUILT/lib/gcc/$EABIARCH/4.8/libgcc.a || exit 1

it seems the error occurs in ndk-r9. I downloaded ndk-r8b and it works as expecting.

I am use ndk-r9c, in build_android.sh, change "-z,noexecstack" to "-z noexecstack", and delete "--warn-once", then build OK.
