Handling Problems with FaCT++ not Finding Libraries

The C++ compile

In Progress...

Note that if you do this on a Mac then Xcode 2.2 or greater is recommended in order to get a universal binary.

First checkout FaCT++ with the command line call:

svn checkout http://factplusplus.googlecode.com/svn/trunk/ factplusplus.

We now need to edit the Makefile.include to use the options associated with the correct version of gcc. First we find the version of gcc with the command line

gcc -v

On my linux machine the result was

Reading specs from /usr/lib/gcc/i386-redhat-linux/3.4.6/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=i386-redhat-linux
Thread model: posix
gcc version 3.4.6 20060404 (Red Hat 3.4.6-9)

So I modified the Makefile.include so that the GENERAL_DEFINES were

GENERAL_DEFINES = $(GCC_OPT_OPT) $(GCC_34_OPT) $(ALL_DEF)

Now much of the building progresses fine. But it seems that building the jnilibrary does not work on most machines. So here are some machine specific options for how to finish the build.

Linking the JNI Library in os x.

The commands

cd FaCT++.JNI
g++ -dynamiclib -framework JavaVM -I/System/Library/Frameworks/JavaVM.framework/Headers \
  obj/FaCTPlusPlus.o ../Kernel/obj/*.o ../Bdd/obj/*.o -o obj/FaCTPlusPlus.jnilib

compile but don't work at runtime.

The Java Compile

There is no build file for the java file so we go back to basic java commands. Set the owlapi variable to the location of the owlapi jar file, e.g.

owlapi=~/dev/workspaces/protege4/owleditor/plugins/org.semanticweb.owl.owlapi/lib/owlapi-bin.jar

Then the command line

javac -cp $owlapi -d classes -g `find FaCT++.Java -name "*.java"`

works - though there were some compile errors that were easily fixed and I agreed with the compiler. Then

cd classes
jar -cf ../FaCTPlusPlus.jar `find . -name "*.class"`

finishes the job.
