Install notepadqq on Debian 8 (jessie)

13 Comments

Notepadqq is a version of notepad++ adapted for Linux. I love notepad++ for its powerful features and also because it’s free. Notepadqq has a ppa configured for easy installation for Ubuntu users, but for everyone else they must resort to compiling it. Fortunately it’s not too complicated. Thanks to linuxbabe for the guidance.

For Debian 8 users this is what you have to do:

sudo apt-get install qt5-qmake libqt5webkit5 libqt5svg5 coreutils libqt5webkit5-dev libqt5svg5-dev qttools5-dev-tools git
git clone https://github.com/notepadqq/notepadqq.git
cd notepadqq
./configure
make
sudo make install

After a bit of time notepadqq will be compiled and installed. That’s it!

If you are running gnome-shell or a derivative (such as cinnamon) then you can get your newly installed program to show up in the menu by pressing alt+f2, hitting r, and then hitting enter. This causes the shell to reload so it will pick up your newly installed program.

Compile ffmpeg on CentOS 7

2 Comments

Recently I had to compile ffmpeg from scratch on CentOS 7. The reason? I wanted libfdk_aac support. Here are my notes on the procedure. The how-to on https://trac.ffmpeg.org/wiki/CompilationGuide/Centos was actually quite helpful and accurate.

Install necessary dependencies and set up build folder

yum install autoconf automake cmake freetype-devel gcc gcc-c++ git libtool make mercurial nasm pkgconfig zlib-devel
mkdir ~/ffmpeg_sources

Build necessary components
I only needed x264 and libfdk_aac, so that’s all I ended up doing:

#yasm
cd ~/ffmpeg_sources
git clone --depth 1 git://github.com/yasm/yasm.git
cd yasm
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install
make distclean
#libx264
cd ~/ffmpeg_sources
git clone --depth 1 git://git.videolan.org/x264
cd x264
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
make
make install
make distclean
#libfdk_aac
cd ~/ffmpeg_sources
git clone --depth 1 git://git.code.sf.net/p/opencore-amr/fdk-aac
cd fdk-aac
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
make distclean

Compile ffmpeg
I actually specified a git mirror because the sources at ffmpeg site were glacially slow.

cd ~/ffmpeg_sources
git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg
PKG_CONFIG_PATH="$HOME/FFmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/FFmpeg_build" --extra-cflags="-I$HOME/FFmpeg_build/include" --extra-ldflags="-L$HOME/FFmpeg_build/lib" --bindir="$HOME/bin" --pkg-config-flags="--static" --enable-gpl --enable-nonfree --enable-libfdk-aac  --enable-libx264
make
make install
make distclean
hash -r

Optionally, remove existing ffmpeg

sudo yum remove ffmpeg

That was it! After a bit of compile time ffmpeg worked with the items I wanted it to.
