The libjpeg sources are not in the git sources but are normally downloaded during the build process. If you build the entire solution that should not be a problem since it has the project dependencies set: libjpeg.2012
depends on Download libjpg.2012
, which means the latter gets built before the first. All Download libjpg.2012
is run a cscript
which downloads libjpeg from http://www.ijg.org/files/jpegsrc.v8d.tar.gz (see inside the project file).
So if you do not have the sources, either you are building incorrectly (not in VS for instance, or with a broken solution file) or the download script is broken. In that case, you should inspect the output: I assume it shows errors when it can not download the libs.
