Compile with MozJPEG

[adrianmihalko]

I am not a CLI master, can you please provide me more details about how to compile with MozJPEG support?

I tried:

$ ls /opt/mozjpeg
bin  include  lib64  share

Now it runs fine, but I am not sure if it is using the mozjpeg library.

 jpegoptim -m 91 120,902.jpg -d ./hello/
 cjpeg -quality 91 120,902.jpg > ./hello/comp91.jpg

-rw-rw-r-- 1 madrian madrian 91089 Dec 17 15:30 comp91.jpg

So the 2 files has different file sizes.

Had to add /opt/mozjpeg/lib64 to ldconfig manually, but now jpegoptim creates files 3-4% smaller than before.
echo '/opt/mozjpeg/lib64/' > /etc/ld.so.conf.d/mozjpeg.conf && ldconfig

a buddy and I were just talking about this yesterday and he came up with these instructions, which also work on Mac OS if you have homebrew installed (for pkg tools). Just for reference if anyone wants the steps to do this. Props to @wseemann :

# get the depdendencies (view brew)
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install pkg-config autoconf automake libtool nasm

# get mozjpeg
wget https://github.com/mozilla/mozjpeg/releases/download/v3.2/mozjpeg-3.2-release-source.tar.gz
tar -xvf mozjpeg-3.2-release-source.tar.gz
cd mozjpeg-3.2-release-source

# build mozjpeg
autoreconf -fiv
./configure
make
sudo make install

# get jpegoptim
git clone https://github.com/tjko/jpegoptim.git
cd jpegoptim.git

# build jpegoptim
./configure CPPFLAGS=-I/opt/mozjpeg/include LDFLAGS=-L/opt/mozjpeg/lib
make
sudo make install

# run it (from terminal)
jpegoptim -V

a bit late but it might be helpful to somebody else
I compiled it with mozjpeg on windows with gcc just by using the switch
./configure --with-libjpeg=/d/mozjpeg-3.3.1/.libs
I had to manually copy the mozjpeg include files (jconfig.h, jerror.h, jmorecfg.h, jpeglib.h, turbojpeg.h) to C:\msys64\mingw64\include\ or the ./configure script couldn't find them
but this is doable on linux too if you don't want to install the mozjpeg binaries just pass the path to where libjpeg.a is and copy the above mentioned include files to /usr/local/include (you can delete them after compile)

[dvershinin]

Users of CentOS / RedHat 7 may want to install jpegoptim compiled with MozJPEG using these instructions (no compilation required, ready to install package).

[ozcoder]

If you are OK with using ABI 8 of libjpeg then this works.
Build mozjpeg and install to prefix of /usr/local

mkdir build
cd build
cmake -GUnix Makefiles ../ -DCMAKE_INSTALL_PREFIX=/usr/local -DWITH_JPEG8=1
make
sudo make install/strip

Now build jpegoptim

./configure --with-libjpeg=/usr/local
make
make strip
sudo make install

Now as root, tell jpegoptim where the library is
echo '/usr/local/lib/' > /etc/ld.so.conf.d/jpegoptim.conf

[adrianmihalko]

Guys, can you verify what should be the output when mozjpeg is enabled?

I am compiling with

@ubuntu:~/scripts/jpegoptim$ ./configure CPPFLAGS=-I/opt/mozjpeg/include LDFLAGS=-L/opt/mozjpeg/lib64 --with-libjpeg=/opt/mozjpeg/lib64
@ubuntu:~/scripts/jpegoptim$ make
gcc  -g -O2 -I/opt/mozjpeg/include -I/opt/mozjpeg/lib64 -DHAVE_CONFIG_H   -c -o jpegoptim.o jpegoptim.c

gcc  -g -O2 -I/opt/mozjpeg/include -I/opt/mozjpeg/lib64 -DHAVE_CONFIG_H   -c -o jpegdest.o jpegdest.c
gcc  -g -O2 -I/opt/mozjpeg/include -I/opt/mozjpeg/lib64 -DHAVE_CONFIG_H   -c -o misc.o misc.c
gcc  -g -O2 -I/opt/mozjpeg/include -I/opt/mozjpeg/lib64 -DHAVE_CONFIG_H -o jpegoptim jpegoptim.o jpegdest.o misc.o  -L/opt/mozjpeg/lib64 -L/opt/mozjpeg/lib64 -lm -ljpeg
```

Output is:

```
ubuntu:~/scripts/jpegoptim$  /usr/local/bin/jpegoptim -V

@adrianmihalko the output of jpegoptim -V won't be illustrative, because libjpeg version: 6b 27-Mar-1998 will be there irrespective of using the standard library or MozJPEG.

The best way to check if you have successfully compiled MozJPEG in is with ldd /path/to/jpegoptim | grep jpeg. If the output is empty, it means the library was linked in statically.

Thank you, based on this I think mozjpeg is enabled:

$ ldd /usr/local/bin/jpegoptim | grep jpeg
libjpeg.so.62 => /opt/mozjpeg/lib64/libjpeg.so.62 (0x00007f7ee9b70000)

[ozcoder]

If you want some more detail

$ ldd /usr/local/bin/jpegoptim | grep -i jpeg | tr -d "\n" | cut -d">" -f2 | cut -d' ' -f2 | xargs -i{} strings {} | grep mozjpeg

mozjpeg version 4.0.0 (build 20191127)

I think after 3 years I can close this issue. Thanks for tips.
