Can't build using Amazon Linux

[ccoffey]

I've been struggling to build ffmpegthumbnailer on Amazon Linux for the past hour and I'm looking for some help. Below is the beginning of a set of steps.

Amazon Linux has cmake version 2.8.12.2 installed by default, we need a newer version.

1. Get newest version of cmake

wget https://cmake.org/files/v3.9/cmake-3.9.1-Linux-x86_64.sh
sh ./cmake-3.9.1-Linux-x86_64.sh

2. Clone ffmpegthumbnailer

git clone https://github.com/dirkvdb/ffmpegthumbnailer.git
cd ffmpegthumbnailer/

3. Attempt to build

/home/ec2-user/cmake-3.9.1-Linux-x86_64/bin/cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GIO=ON -DENABLE_THUMBNAILER=ON .

[dirkvdb]

It cannot find the ffmpeg libraries. Check the .travis.yml in the root of the archive on how to install ffmpeg yourself if needed: line 28-30

[ccoffey]

Thanks for your help @dirkvdb but I must be still doing something wrong! Before step 3 above, lets call it step 2.1 I did as you suggested and this step passed without any errors. However when I subsequently attempt to build ffmpegthumbnailer I still get an error about libavcodec.

2.1. Install ffmpeg libraries

wget http://ffmpeg.org/releases/ffmpeg-3.1.3.tar.bz2
tar xf ffmpeg-3.1.3.tar.bz2
cd ffmpeg-3.1.3 && ./configure --prefix=/usr --disable-static --enable-shared --disable-avdevice --disable-doc --disable-htmlpages --disable-manpages --disable-programs --disable-encoders --disable-muxers --enable-swscale --disable-yasm --enable-protocol=file --enable-protocol=http --enable-iconv  && make -j4 && sudo make install

3. Attempt to build

/home/ec2-user/cmake-3.9.1-Linux-x86_64/bin/cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_GIO=ON -DENABLE_THUMBNAILER=ON .

-- Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR) -- Checking for module 'libavcodec' -- No package 'libavcodec' found CMake Error at /home/ec2-user/cmake-3.9.1-Linux-x86_64/share/cmake-3.9/Modules/FindPkgConfig.cmake:412 (message): A required package was not found Call Stack (most recent call first): /home/ec2-user/cmake-3.9.1-Linux-x86_64/share/cmake-3.9/Modules/FindPkgConfig.cmake:588 (_pkg_check_modules_internal) CMakeLists.txt:56 (PKG_CHECK_MODULES)

[dirkvdb]

Do you have sudo rights on the machine, did you actually install the libraries in /usr? Verify that /usr/lib contains the libavcodec/libavutil/... libraries

[ccoffey]

Yes I have sudo rights on the machine.

Here is what I executed

cd ffmpeg-3.1.3
./configure --prefix=/usr --disable-static --enable-shared --disable-avdevice --disable-doc --disable-htmlpages --disable-manpages --disable-programs --disable-encoders --disable-muxers --enable-swscale --disable-yasm --enable-protocol=file --enable-protocol=http --enable-iconv  && make -j4 && sudo make install

and the output that I got was

[dirkvdb]

What is the output of pkg-config --cflags libavcodec

[ccoffey]

pkg-config --cflags libavcodec

Package libavcodec was not found in the pkg-config search path. Perhaps you should add the directory containing `libavcodec.pc' to the PKG_CONFIG_PATH environment variable No package 'libavcodec' found

[dirkvdb]

pkg-config is not able to find the ffmpeg library description files, they should be in /usr/lib/pkgconfig

[ccoffey]

ls /usr/lib/pkgconfig

libavcodec.pc libavfilter.pc libavformat.pc libavutil.pc libswresample.pc libswscale.pc

Is there something weird about pkg-config and Amazon Linux?

Is PKG_CONFIG_PATH suppose to be set to something? I'm getting nothing for echo $PKG_CONFIG_PATH

[dirkvdb]

try setting it to /usr/lib/pkgconfig and see if it helps

[ccoffey]

Ok so the following gets me one step further

2.2 Set PKG_CONFIG_PATH on Amazon Linux

export PKG_CONFIG_PATH=/usr/lib/pkgconfig

png support = disabled above looks worrying, I see your script has sudo apt-get install libpng-dev I'm guessing I need to do the equivalent for yum.

[dirkvdb]

you need to have the png development libraries installed yes

[ccoffey]

sudo yum install libpng-devel

So close and yet so far!!!

[dirkvdb]

I have never used yum. But make sure your system is updated before trying to install the lib.

[ccoffey]

Ok it looks like I managed to get it working

Where is the binary tho? I was hoping to do something like bin/ffmpegthumbnailer --version or something to verify that its built correctly and working.

[ccoffey]

Weird

make
sudo make install
ffmpegthumbnailer
ffmpegthumbnailer: error while loading shared libraries: libffmpegthumbnailer.so.4: cannot open shared object file: No such file or directory

[ccoffey]

Not really sure whats wrong here, any ideas?

[ccoffey]

Finally got it! I had to do the following!

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/local/lib64

Then I can do

ffmpegthumbnailer -v
ffmpegthumbnailer version: 2.2.0

[dirkvdb]

Your system seems to behave weird when it comes to library locations. Setting the LD_LIBRARY_PATH manually will always do the trick. Good to see you git it working.

[tanya-an]

@dirkvdb I'm trying to build ffmpegthumbnailer on Amazon Linux AMI, and I need help. Here are all my steps:

git clone https://github.com/dirkvdb/ffmpegthumbnailer.git
cd ffmpegthumbnailer/
make
sudo make install

ffmpeg version 4.1-static https://johnvansickle.com/ffmpeg/ cmake-3.13.1-Linux-x86_64
