Hi,

I am stumped about how to link a program such as the example trange1.pp into a jar file. I've followed the instructions here: http://wiki.freepascal.org/FPC_JVM

and the command

java -cp /full/path/to/fpcjvm/units/jvm-java/rtl:. trange1

works fine.

But I would like to make it a jar file. How? My google-foo has failed me.

Thanks,

Andrew Haines

Just create jar file the usual way. However, you'll need to give FPC-JVM RTL classes as well (those in org.freepascal namespace)

Ok, I'm not sure of the usual way but here's what I've tried:

~/downloads $ jar cf trange1.jar trange1.class
/usr/local/lib/fpc/2.7.1/units/jvm-java/rtl/.
~/downloads $ java -jar ./trange1.jar
Failed to load Main-Class manifest attribute from
./trange1.jar

also

~/downloads $ jar cfm trange1.jar manifest.txt
trange1.class /usr/local/lib/fpc/2.7.1/units/jvm-java/rtl/. ~/downloads $ java -jar ./trange1.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/freepascal/rtl/TObject

Program will exit.

where manifest.txt is
Main-Class: trange1

I've played around with MainClass: trange1.class MainClass Main main

Any hints?

Thanks,

Alright I've figured it out:

jar cfm trange1.jar manifest.txt trange1.class -C
/usr/local/lib/fpc/2.7.1/units/jvm-java/rtl/ .

then

java -jar trange1.jar works
