从源代码构建libjepeg-turbo不会构建库libturbojpeg.so *

Question

I'm trying to build libjpeg-turbo from source to include 12 bit support. I downloaded the source code from here (2.0.1) then followed instruction given in Building.md

    cd libjpeg-turbo-2.0.1 
    mkdir build && cd build
    cmake -G"Unix Makefiles" -D WITH_12BIT=1 -D WITH_TURBOJPEG=1 ..
    make -j8
    sudo make install

The compilation is successful and generates only libjpeg.so , libjpeg.so.62 and libjpeg.so.62.3.0 along with bunch of other binary files. But its not building the lib files libturbojpeg.so.0.2.0 , libturbojpeg.a and libturbojpeg.so which i need. I'm not sure where I am going wrong. i have also tried without the -D WITH_TURBOJPEG flag.

I'm trying this on Ubuntu 16.04 on Nvidia Tx2.

Any help is greatly appreciated.

Thanks

Answer 1

Line 201 of CMakeLists.txt turns WITH_TURBOJPEG off when building with WITH_12BIT enabled.

Don't enable WITH_12BIT and then WITH_TURBOJPEG will be default enabled and should build those libraries.
