Build Errors about v4l2test HOT 14 CLOSED

I checked you android.mk, I found it missing "\" ??

for example:

in yours
LOCAL_SRC_FILES :=
v4l2test.cpp
ffjpeg.cpp
camdev.cpp

but it shoud like this:
LOCAL_SRC_FILES :=
v4l2test.cpp \
ffjpeg.cpp \
camdev.cpp

maybe you are missing the "\". (or the github web display bug ?)

I built these codes under Allwinner A33 android 4.4 source code enviroment.
In theory it is possible using NDK, but I suggest you using NDK version which corresponding to the Android4.4.

good luck.

I checked and "" are in the mk file. It looks like a github web display bug. could you share your NDK toolchain mentioned in the readme (arm-linux-androideabi-4.7.1-full-linux-x86.tar.bz2)?

from v4l2test.

arm-linux-androideabi-4.7.1-full-linux-x86.tar.bz2
no problem, but how to give it to you ? about 39MB size.

from v4l2test.

I upload it to the Baidu cloud, please try download:

Got it. Thanks

from v4l2test.

dose it compile success now ? or not ?

from v4l2test.

Not yet. A seperate makefile is needed to build test programs using arm-linux-androideabi-4.7.1-full-linux-x86.tar.bz2 toolchain. Do you already have such a makefile?

from v4l2test.

sorry. I only use arm-linux-androideabi-4.7.1-full-linux-x86 toolchain to build ffmpeg library for v4l2test.
the source code of v4l2test need build using NDK or in android source code building enviroment.
the arm-linux-androideabi-4.7.1-full-linux-x86 toolchain is a standalone toolchain for android, it means you can use it to build c/c++ source without NDK.

from v4l2test.

Okay. I want to build v4l2test without using NDK. As I have build errors with NDK. How did you build v4l2test without using the NDK? Did you create a makefile to build c/c++ (e.g. v4l2test) using the arm-linux-androideabi-4.7.1-full-linux-x86 stnadalone toolchain?

from v4l2test.

some source code of v4l2test using android header files, example:

in camdev.h
#include <gui/Surface.h>
#include <gui/SurfaceComposerClient.h>
#include <gui/ISurfaceComposer.h>
#include <ui/DisplayInfo.h>
#include <ui/GraphicBufferMapper.h>

these header files are not included in the standalone toolchains.

so you need NDK and download related android source code or header files.

I sugguest you download the android 4.4 source code, and try to build it.

my build steps in android source code enviroment:

1. cd android-source dir
2. copy v4l2test to android-source dir
3. source build/envsetup.sh
4. lunch (select a device combo)
5. make -j8 (this will make whole android source code )
6. mmm v4l2test -B (this will build v4l2test project)

Thanks. I managed to build it.

from v4l2test.

great

from v4l2test.

you write a new makefile ?
could you please share you modification, this maybe helpful for other peoples.
thank you.

from v4l2test.

Sorry fro the late reply. I didnt make a new makefile. I just followed your steps build the project using mmm v4l2test -B
