Compiling and Running the Example |
The following code shows the contents of a shell script 'test' that will compile and run the test program:
#!/bin/sh # Compile the java program. javac Test.java # Compile the object code, you will probably # need to edit the path # locations to match your system. g++ -c -I/usr/java/include -I/usr/java/include/linux Test.cpp # Build the shared library libtest.so # (edit to fit your system/compiler). g++ -shared -Wl,-Bstatic -o libtest.so Test.o # Ensure the shared library is on the local path. export LD_LIBRARY_PATH=. # Run the test java program. java Test |
A correct invocation of the script should look like:
$ sh test Before calling the world of C! After calling the world of C! |
There will be a pause when the script is run while it compiles the source of the Java and C++ code. On a faulty platform, the Java program will abort before the line "After calling the world of C!" is output.
