Release Notes
|
||||
--------------
|
||||
This version of the library has been tested under the following OS:
|
||||
- RedHat Linux 9.0
|
||||
|
||||
You should be able to link progams with the -lopenjpeg option after the library is compiled and installed.
|
||||
You can also statically link with libopenjpeg.a.
|
||||
If you use a really old version of gcc and it chokes on the CRs in the file, you can type 'make dos2unix'
|
||||
to run all of the files through dos2unix which converts CRLF to LF. This no longer appears to be required
|
||||
for RedHat 7.3 or 9.
|
||||
|
||||
Please let us know how this works for you under other Linux distributions or any other *nix.
|
||||
|
||||
Installation
|
||||
------------
|
||||
Note: You will need to have root privileges in order to install the library in the /usr/lib directory.
|
||||
The installation process is as simple as this :
|
||||
1) Enter the OpenJPEG directory
|
||||
2) Build the distribution :
|
||||
make
|
||||
make install
|
||||
3) Clean all files produced during the build process
|
||||
make clean

Release Notes
|
||||
--------------
|
||||
This version of the library has been tested under OSX 10.2 using gcc 3.3.
|
||||
|
||||
While the makefiles will make a .dylib and a .a, it is recommended to simply staticly link with the .a file.
