Hello,
I recently download the FastCV SDK. I want to compile the examples supplied with it.
I go into samples/fastcvdemo and I tape : make
I get that error:
Host OS was auto-detected: linuxAndroid NDK: WARNING:jni/apis/featureDetection/Android.mk:fastcvFeatDetect: non-system libraries in linker flags: -lfastcvAndroid NDK: This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIESAndroid NDK: or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of theAndroid NDK: current modulemake[1]: Entering directory `/home/xavier/Qualcomm/fastcv-android-1-7-1/samples/fastcvdemo'/home/xavier/android-ndk-r14b/build/core/build-binary.mk:687: Android NDK: Module fastcvFeatDetect depends on undefined modules: fastcv log GLESv2/home/xavier/android-ndk-r14b/build/core/build-binary.mk:700: *** Android NDK: Aborting (set APP_ALLOW_MISSING_DEPS=true to allow missing dependencies) . Stop.make[1]: Leaving directory `/home/xavier/Qualcomm/fastcv-android-1-7-1/samples/fastcvdemo'Makefile:54: recipe for target 'all' failedmake: *** [all] Error 2
How to use the Makefile file? I don't really understand own to generate my exe file.
Hi,
Follow below steps to build fastcv application with Hexagon SDK 64-bit, if you're platform is different means please replay which platform you're using
FastCV SDK environment setup
FastCV SDK download
https://developer.qualcomm.com/software/fast-cv-sdk/tools
Download v1.7.1 for Linux Embedded
FastCV installation and compilation
The FastCV binary file is fastcv-installer-linuxembedded-1-7-1.bin. Follow the steps below to install it:
chmod 777 fastcv-installer-linuxembedded-1-7-1.bin
./fastcv-installer-linuxembedded-1-7-1.bin
Building Sample Applications
fastcvSimpleTest using Hexagon sdk 64-bit
1. Download Hexagon DSP SDK from Qualcomm developer network
https://developer.qualcomm.com/software/hexagon-dsp-sdk
2. Download gcc-linaro-4.9-2014.11-x86_64_aarch64-linux-gnu.tar.xz
http://releases.linaro.org/archive/14.11/components/toolchain/binaries/aarch64-linux-gnu
Extract the tar file and copy folder gcc-linaro-4.9-2014.11-x86_64_aarch64-linux-gnu
To <Hexagon_SDK_ROOT>/tools/ folder.
Rename gcc-linaro-4.9-2014.11-x86_64_aarch64-linux-gnu folder to linaro64.
3. Copy the fastcvSimpleTest folder inside <Hexagon_SDK_ROOT>/examples/common/.
Copy 64-bit libfastcv.a from libs provided in the fastcv sdk
(fastcv-1-7-1_LinuxEmbedded\lib\64-bit\libfastcv.a) to
<Hexagon_SDK_ROOT>/examples/common/fastcvSimpleTest/lib/ folder.
4. Open a new terminal from the root directory <Hexagon_SDK_ROOT> of the Hexagon SDK
and run setup_sdk_env.source.
This script configures the local environment. These changes are not persistent in the
terminal instance, so you must run setup_sdk_env.source on each terminal you want to
develop in.
$ cd < Hexagon SDK root directory, default is: ~/Qualcomm/Hexagon_SDK/<version>>
$ source setup_sdk_env.source
5. Change the directory to fastcvSimpleTest folder
cd examples/common/fastcvSimpleTest
Execute command: make tree V=UbuntuARM_Debug_aarch64
6. A folder with name "UbuntuARM_Debug_aarch64" should get generated in
the fastcvSimpleTest folder. It will contain the fastcvSimpleTest binary file.
FastCV SDK Test
1. Push the fastcvSimpleTest binary file in the target:
adb push
<Hexagon_SDK_ROOT>\examples\common\fastcvSimpleTest\UbuntuARM_Debug_aarch64\s
hip\fastcvSimpleTest /usr/bin/
2. Change bin permissions and execute the fastcvSimpleTest:
adb shell chmod 777 /usr/bin/fastcvSimpleTest
adb shell /usr/bin/fastcvSimpleTest
