Export the values of the following standard compiler and compiler flag
variables in the main makefile, avoiding the need to pass through each
one to child make processes manually:
CC
CXX
LD
JAVAC
JAVACC
Since JAVAC is manually exported as "$(JAVAC) $(JFLAGS)" by the main
makefile, additionally separate JAVAC and JFLAGS into separate variables
from the perspective of child make processes.
Rename the following makefile variables for the sake of clarity in child
makefiles:
SRC_DIR -> PRISM_SRC_DIR
CLASSES_DIR -> PRISM_CLASSES_DIR
OBJ_DIR -> PRISM_OBJ_DIR
LIB_DIR -> PRISM_LIB_DIR
INCLUDE_DIR -> PRISM_INCLUDE_DIR
IMAGES_DIR -> PRISM_IMAGES_DIR
DTDS_DIR -> PRISM_DTDS_DIR
The helper script src/scripts/printversion.sh also makes use of the
value of SRC_DIR exported from the main makefile, so use PRISM_SRC_DIR
in that script too.
As noted in #68, the javah tool has been removed in JDK10. Here, we switch to the new way of generating the JNI .h files, using the -h option of the regular javac compiler.
We have to adapt all Makefiles (not only those in directories that contain classes with native methods), as javac compiles all required classes (and generates their JNI headers) beyond the directory with the Makefile.
The .h files generated by javac -h had a different naming scheme, now there is a prefix for the package name. To avoid having to touch all the #includes, we generate the new .h files in prism/include/jni and provide legacy headers in the old location and with the old name, forwarding the the corresponding new header. In the future, at an appropriate moment, those legacy headers can be removed and replace with direct includes.
Currently, there is a post-processing step on Windows: After the .h file is generated, dos2unix is called to replace the Windows CRLF line endings. Otherwise, the generated headers show up as changed files in version control. As now there are no special targets for the generation of the .h files anymore, we move to a global post-processing step and call dos2unix on prism/include/jni/*.h at the end of building.
Currently, building PRISM with parallel building does not work,
as there are dependencies between targets that are not fully
encoded in the Makefiles. Building with -j n flag would lead to error.
Now, we add the .NOTPARALLEL target to most of the Makefiles,
which tell GNU make to ignore the -j flag. Note that this
only inhibits parallel builds for the current Makefile, we
thus have to specify it for all sub-Makefiles as well
(see https://www.gnu.org/software/make/manual/html_node/Parallel.html)
For the external libraries, CUDD and LPSolve don't seem to mind building
in parallel, so we don't inhibit there and can get some minor compile time
speed-up by using multiple cores if the -j option is specified.

This method transforms X phi operators to X ("label" & phi).
This will be used to ensure "strong" semantics for the next-step
operator for co-safe LTL reward computations.

There's actually JDK library functionality for a hash map that
uses object identity instead of .equals(), making PlainObjectReference
unnecessary. Use IdentityHashMap instead.
