RXTX 2.2

Latest update with upstream: 2012-01-08

This fork of RXTX patches the upstream sources to introduce the following fixes:

• support to linux ttyACM* devices
• reduced latency (thanks @neophob)
• faster ports listing on Windows boxes with some particular hardware (Bluetooth) configurations (thanks eried from the forum)

Upgrading the source code

Check it out from CVS with the commands

export CVSROOT=:pserver:anonymous@qbang.org:/var/cvs/cvsroot
cvs login # (then hit return)
cvs checkout -r commapi-0-0-1 rxtx-devel

Compiling on linux

Have the necessary tools in place: on debian/ubuntu apt-get install build-essentials should suffice. Then, in the repo folder, run:

mkdir build
../configure
make

and get the resulting files: they should be in folder YOUR_ARCH/.libs/.

If you are using a 64 bit Linux, you can produce 32 bit binaries too: run apt-get install gcc-multilib then run

mkdir build
CFLAGS="-m32" ../configure
make

Compiling on windows

Have the necessary tools in place. These are:

• git
• Visual C++ 2010 Express
• Windows SDK 7.1
• Java Development Kit 1.4 (any JDK should actually suffice)
• JUnit.jar placed somewhere on your hard drive

After you have cloned the repo, run:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools>vsvars32.bat
Set­ting envi­ron­ment for using Microsoft Visual Studio 2010 x86 tools.
C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools>cd C:\RXTX\

C:\RXTX> mkdir build
C:\RXTX> copy Makefile.msvc build\Makefile
C:\RXTX> cd build
C:\RXTX\build> set path=%PATH%;"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin"

Then edit Makefile and correct path variables, in particular: JAVA_HOME, JUNIT_JAR, JAVAC, JAR, JAVAH, JAVA. Finally run:

C:\RXTX\build> nmake serial

Thanks to @neophob for his blog page.

Compiling on macosx

Have the necessary tools in place. These are:

• git
• Java 1.6
• XCode Command Line Tools
• glibtool

Then, in a new terminal, clone the repo, cd into its folder, then:

mkdir build
cd build
rm -rf *
CFLAGS="-arch i386" LDFLAGS="-arch i386" sh ../configure
sed -e 's|/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/../../../Headers|/System/Library/Frameworks/JavaVM.framework/Versions/Current/Headers|g' -i '' Makefile
sed -e 's|$(SHELL) glibtool|$(SHELL) glibtool --tag CC|g' -i '' Makefile
make
