JasPer-4.2.4

Introduction to JasPer

The JasPer Project is an open-source initiative to provide a free software-based reference implementation of the JPEG-2000 codec.

[Note]

Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

JasPer Dependencies

Required

CMake-3.31.1

Recommended

libjpeg-turbo-3.0.1

Optional

Freeglut-3.6.0 (required for jiv), Doxygen-1.12.0 (needed for generating html documentation), and texlive-20240312 (needed to regenerate the pdf documentation)

Installation of JasPer

[Note]

Note

The tarball jasper-4.2.4.tar.gz will extract to jasper-version-4.2.4.

Install JasPer by running the following commands: 

mkdir BUILD &&
cd    BUILD &&

cmake -D CMAKE_INSTALL_PREFIX=/usr    \
      -D CMAKE_BUILD_TYPE=Release     \
      -D CMAKE_SKIP_INSTALL_RPATH=ON  \
      -D JAS_ENABLE_DOC=NO            \
      -D ALLOW_IN_SOURCE_BUILD=YES    \
      -D CMAKE_INSTALL_DOCDIR=/usr/share/doc/jasper-4.2.4 \
      ..  &&
make

To test the results, issue: make test.

Now, as the root user: 

make install

Command Explanations

-D CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes cmake remove hardcoded library search paths (rpath) when installing a binary executable file or a shared library. This package does not need rpath once it's installed into the standard location, and rpath may sometimes cause unwanted effects or even security issues.

-D JAS_ENABLE_DOC=NO: This option disables rebuilding the pdf documentation if texlive-20240312 is installed.

-D ALLOW_IN_SOURCE_BUILD=YES: This switch allows building from within the source tree. In our case, this is needed to allow us to build inside of the BUILD directory instead of needing to create another directory outside of the source tree.
