imported Iakin's public domain jcpuid library allowing the detection of CPU types from java imported Iakin's modifications to jbigi to use the jcpuid library in detecting what jbigi implementation to load imported and slightly updated Iakin's scripts to build jbigi for lots of architectures (yay iakin!)

* libjbigi: - Add documentation on dynamic build option - Add two speed tests to the build script - Clean up the build script, make it easier to build dynamic

Execute the build.sh script to produce jbigi library files optimized for a number of different CPU-types.

* JBigI: - Replace old non-PIC 62-bit linux libs (GMP 4.1.4 built in 2005) with PIC libs built with GMP 5.0.2. License is LGPLv3. Built by sponge with GCC 4.4.4, downloaded from http://sponge.i2p/files/jbigi/gmp-5.0.2/ For 64-bit processors, both performance testing and the GMP changelog led us to use 5.0.2 for both the 32- and 64-bit versions, even though the files are twice as big. See http://zzz.i2p/topics/306 for discussion and test results. libjbigi-linux-athlon64.so was a 64 bit file; by the new naming standard supported by NativeBigInteger, it is now a 32-bit file and the 64-bit one is libjbigi-linux-athlon64_64.so. All new 64-bit libs will have _64 appended. - Update build docs

===========================
update of jbigi scripts - merge mbuild_jbigi.sh into build_jbigi.sh and drop mbuild_jbigi.sh - make build.sh's tests optional - try to determine the locations of JAVA_HOME and I2P
2012-01-08 23:23:00 +00:00
Some linux distributions come bundled with GMP.

Try 'locate lib/libgmp.so' to see.

In Debian/Ubuntu, install the the libgmp3-dev package to get the libgmp headers.

Then export I2P=/path/to/your/i2p/install.
Then do 'build.sh dynamic'. This will do a quick build using your installed libgmp library
and then test it and the jbigi in your I2P installation to see which is faster.
If the new jbigi is slower, then run 'build.sh' (without the 'dynamic'), which will download

The best way of building the jbigi dll's is to install Mingw {URL} and msys {URL}.
The combination of these two should be able to run the included build-scripts without modifications.
