I have cloned the repo, and installed boost and boost-build using Homebrew on the Mac. I copied the configuration files as instructed, but I am getting this error with b2 release: ~/src/owlcpp $ b2 release /usr/local/Cellar/boost-build/1.76.0/share/boost-build/src/build/project.jam:259: in find-jamfile from module project error: Unable to load Jamfile. error: Could not find a Jamfile in directory '/usr/local/Cellar/boost/1.76.0'. error: Attempted to find it with pattern '[Bb]uild.jam [Jj]amfile.v2...

I intend to work with owlcpp and in the installation process I need to install Boost. I am working on the version of ubuntu 18.04. When I try to run the example for testing: b2 release I have this error: 'boost-build /usr/include/boost ;' but we were unable to find "bootstrap.jam" in the specified directory or in BOOST_BUILD_PATH (searching /usr/include/boost, /usr/share/boost-build). When I install or Boost generated header file is in /usr/local/lib/boost/include, and the binary library file is...

owl-cpp uses FaCT++ with the Boost license, but the FaCT++ project is GNU 2 software. My company is interested in using (and contributing) open source software so long as it isn't viral, but it would seem that use of FaCT++ would make all software that uses it subject to the GNU 2 license. Am I wrong that owl-cpp's dependency on FaCT++ code makes it "viral" in the sense intended by the FSF's GNU license terms?

Dear Mikhail! Thanks for taking care of this project! This is to report, that the last versions of FaCT++ (e.g. 1.7.0, see https://bitbucket.org/dtsarkov/factplusplus) have slightly changed folder layout, so compilation fails.

Hi all, I'm trying to get inferred equivalence for classes with FaCT++. I guess I have to use the following method : "get_sub_super" ? Anyone have an example of this method usage ? Especially for the firt parameter (Predicate). Best regards, Yves

Hi Mikhail, Are there example of usage of FaCT++ for inferred triple retreiving ? I saw the Kernel class. But I don't know exactly how to retreive inferred triple after ontology submission. My ontology is consistent and all classes are satisfiables. FaCT++ have generated some axioms. Best regards, Yves

Hi, I'm trying to build an application using OWPCPP and the FaCT++ reasoner. During the link step I have the following error : libowlcpp_logic.so : undefined reference to « vtable for TIndividual » I suspect the Save and Load method to not be implemented. I'm trying to find an example of application using owpcpp and fact++ by without success. Anyone have an idea ? BR, Yves Teissier

Hello, I was trying to build owlcpp in Ubuntu 14.04 with Boost version 1.65.1, Raptor library 2-2.0.15, libxml library version 2-2.9.0, Fact++ library version 1.6.3. When I fire the command "b2 release" from owlcpp library then I get the following error: /home/sounak/OWL_CPP/boost_1_65_1/tools/build/src/build/toolset.jam:44: in toolset.using ERROR: rule "ext/raptor.init" unknown in module "toolset". /home/nei-admin/OWL_CPP/boost_1_65_1/tools/build/src/build/project.jam:1053: in using external/jamfile.jam:15:...

After a lot of version issues with the various dependencies, the compilation and linking succeeds. I try one of the example programs, "validate.cpp", and I get a segmentation fault. I want to debug, so I re-compile using the debug option, "b2 debug". But the debug version doesn't seg fault! It works fine! Intrigued, I use gdb on the release version anyway (lack of "debugging symbols" notwithstanding). Here is the backtrace, for your information: Reading symbols from validate...(no debugging symbols...

It does not find your subject and returns a null pointer. You are looking for a blank node, right? Have you tried using tripple_store.find_blank(n, did)?

Hi, I have an issue when I want to build the owlcpp lib. I think I have correctly installed Boost.build (boost-build-2014-10.tar.bz2). After untar the archive I have launched : /> b2 install --prefix= I have copied the owlcpp/doc/boost-build.jam to owpcpp/apps and I have set the path to: boost-build "boost_build_dir" ; I have copied the user-config.jam to my home directory and modified the following lines: using gcc ; constant BOOST : "/media/sf_Documents/SCHNEIDER/XDI/TOOLS/OWL_LIBS/OWLCPP/boost-build"...

I have solved my problem. It's was due to a wrong version of libxml2 (2.9.3 instead 2.9.0). This is my working configuration: ** /> cat user-config.jam using gcc ; constant BOOST : "/media/sf_Documents/SCHNEIDER/XDI/TOOLS/OWL_LIBS/OWLCPP/boost_1_53_0" 1.53.0 ; constant LIBXML2 : "/media/sf_Documents/SCHNEIDER/XDI/TOOLS/OWL_LIBS/OWLCPP/libxml2-2.9.0" 2.9.0 ; constant RAPTOR : "/media/sf_Documents/SCHNEIDER/XDI/TOOLS/OWL_LIBS/OWLCPP/raptor2-2.0.8" 2.0.8 ; constant FACTPP : "/media/sf_Documents/SCHNEIDER/XDI/TOOLS/OWL_LIBS/OWLCPP/FaCT++-1.6.2"...
