Hi there, I'm packaging rxtx. It's a native library to be able to access the serial ports from Java. It provides this support for Linux - it works on i386 and I don't see any problems why it shouldn't work on other architectures. How can I verify my opinion?
My problem mentioned in the subject is that I need different parts of
the package at different locations for the different Sun JDKs (1.1 and
1.2). Therefor I put the files into separate directories and create
symlinks into the *existing* JDKs. And this is the first problem. The
package is not usable if the JDK is installed afterwards or
reinstalled/upgraded and so on.
So far this is my postinst:
<---------------
#!/bin/sh
set -e
RXTXJDK11PATH=/usr/lib/jdk1.1/lib
RXTXJDK12PATH=/usr/lib/jdk1.2/jre/lib/ext
case "$1" in
configure*)
ldconfig
# JDK 1.1
if [ -f $RXTXJDK11PATH/classes.zip ]; then
if [ -L $RXTXJDK11PATH/jcl.jar -o -e $RXTXJDK11PATH/jcl.jar ]; then
echo " "
else
echo "creating symlinks for JDK 1.1"
cd $RXTXJDK11PATH; ln -s ../../../share/java/jcl.jar .
fi
fi
# JDK 1.2
if [ -d $RXTXJDK12PATH ]; then
if [ -L $RXTXJDK12PATH/jcl.jar -o -e $RXTXJDK12PATH/jcl.jar ]; then
echo " "
else
echo "creating symlinks for JDK 1.2"
ARCH=`dpkg --print-architecture`
echo "Arch: $ARCH"
cd $RXTXJDK12PATH; ln -s ../../../../../share/java/jcl.jar .
#jdk1.2/jre/lib/i386:
cd $RXTXJDK12PATH/../../$ARCH/; ln -s /usr/lib/libSerial.so .
fi
fi
echo "This serial driver has to be enabled through modifying
javax.comm.properties"
echo "provided by the javax.comm package from sun. You may copy a file
with the "
echo "right content named /etc/javax.comm.properties."
echo
echo "The javax.comm package from sun has to be installed, too."

Now running lintian...
W: lib-rxtx-java: dpkg-print-architecture-in-maintainer-script postinst:26
Why is lintian complaining about the print-architecture?? The compiled
library is architecture dependent - of course.
My main problem now is: How can I remove safely the with postinst
created symlinks in postrm?
javax.comm.properties is file that is provided through the CommAPI
package from Sun. But it has to be modified to use the right library
or better the right interface driver. Is it okay to put the modified
file into /etc?
<-------------- /etc/javax.comm.properties
Driver=gnu.io.RXTXCommDriver

Depends: jdk1.1 | jdk1.2 | jdk1.1-native | jdk1.2-native
Suggests: jdk-common
Installed-Size: 76
Maintainer: Christian Leutloff <[EMAIL PROTECTED]>
Source: rxtx
Description: native interface to serial ports in java
This is a native library for jdk 1.1.*/1.2.*.
.
The CommAPI (javax.comm.*) from Sun is additionally needed to be able
to program the serial interfaces.
Due to the problem with the removal of symlinks the package is only
available from http://www.oche.de/~leutloff/debian/packages/.
Thanks in advance
Christian
