Prior to building the jbigi library, you will need to fetch the GMP source
|
2008-02-27 15:18:32 +00:00
|
|
|
from http://www.swox.com/gmp/, saving it to jbigi/gmp-4.2.2.tar.bz2 (it will
|
2004-08-21 07:56:53 +00:00
|
|
|
be unpacked and built as necessary).

|
Version 4.2.2 has not been extensively tested with I2P. If you would like
|
|
|
|
|
to use a well-tested version, get gmp-4.1.4.tar.bz2, and edit jbigi/build.sh
|
|
|
|
|
to change the version number.

To build the native jbigi and jcpuid libraries for the current host CPU,
|
|
|
|
|
simply run sh build.sh and the results will be packaged up into jbigi.jar
|
2008-02-27 15:18:32 +00:00
|
|
|
and the libjbigi.so library. To test, copy jbigi/lib/libjbigi.so
|
|
|
|
|
and jcpuid/lib/freenet/support/CPUInformation/libjcpuid-*.so
|
|
|
|
|
to your i2p/ directory. You can also copy jbigi.jar to the i2p/lib/ directory;
|
|
|
|
|
it will be used only if the router fails to load the native library.

|
|
|
|
To build the native jbigi libraries for all supported CPUs (on the current OS),
|
|
|
|
|
go into jbigi/ and run build-all.sh (the results will be under jbigi/lib/)

|
|
|
After copying the files to the i2p/ directory,
|
|
|
|
|
to run a speed test comparing the native library to the java library,
|
|
|
|
|
run the shell script below.
