Introduction to JasPer
The JasPer Project is an
open-source initiative to provide a free software-based reference
implementation of the JPEG-2000 codec.
This package is known to build and work properly using an LFS 12.2
platform.
Package Information
JasPer Dependencies
Required
CMake-3.30.2
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
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.
