Andreas,
The problem is a CMake issue with how ';' is interpreted. In the
USE_JAVA.CMAKE file (lines 227-243):
> if (_JAVA_COMPILE_FILES)
> # Compile the java files and create a list of class files
> add_custom_command(
> TARGET ${_TARGET_NAME}
> COMMAND ${CMAKE_Java_COMPILER}
> ${CMAKE_JAVA_COMPILE_FLAGS}
> -classpath ${CMAKE_JAVA_INCLUDE_PATH_FINAL}
> -d ${CMAKE_JAVA_CLASS_OUTPUT_PATH}
> ${_JAVA_COMPILE_FILES}
> COMMAND ${CMAKE_COMMAND}
> -DCMAKE_JAVA_CLASS_OUTPUT_PATH=${CMAKE_JAVA_CLASS_OUTPUT_PATH}
> -DCMAKE_JAR_CLASSES_PREFIX="${CMAKE_JAR_CLASSES_PREFIX}"
> -P ${_JAVA_CLASS_FILELIST_SCRIPT}
> WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
> COMMENT "Building Java objects for ${_TARGET_NAME}.jar"
> )
> endif (_JAVA_COMPILE_FILES)
Line 233
> -classpath ${CMAKE_JAVA_INCLUDE_PATH_FINAL}
On windows with the VS generator this converts the ';' characters to spaces. I
can't remember how to adjust this line so that this classpath value is correct
on all platforms? This is were I hope a CMake guru could help.
So in summary, two issues; the classpath on windows and my suggested addition
of the ${_TARGET_NAME}_CLASSPATH variable. Everything else is fine with me!
I owe you a lunch for making my task easy,
Allen
