FFmpeg unable to compile for DeckLink Duo

Dear all,

A couple of days ago I installed a DeckLink Duo on my computer.
I updated the driver as soon as I restarted the desktop.
I first downloaded the latest Blackmagic DeckLink SDK 10.11.4
And secondly I downloaded FFmpeg from the official git.

I tried to configure with --enable-decklink, --extra-cflags and --extra-ldflags

Here is the command I made:

Code: Select all

sudo PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-cflags="-I$HOME/Blackmagic\ DeckLink\ SDK\ 10.11.4/Linux/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --extra-ldflags="-L$HOME/Blackmagic\ DeckLink\ SDK\ 10.11.4/Linux/include" --extra-libs="-lpthread -lm" --bindir="$HOME/bin" --enable-decklink --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-nonfree && PATH="$HOME/bin:$PATH" make && make install


However I get the following message: C compiler test failed.

I am on ubuntu 18.04.1

I do not know what is my mistake, your help is very welcome.
Please ask me if I forgot to mention any relevant data.

Look into the config.log

Thank you for your comment,
It was not happy with the spaces in the default Blackmagic Decklink SDK folder's name.
I replace it with underscore and now it is compiling.
