/usr/bin/java seems to belong to a pure Java runtime installation: JNI headers (most prominently jni.h) were not found. If they happen to reside at a different location, please specify it using --with-jni-headers option (but double-check upfront whether they really suit the chosen Java environment)...

These errors are due to the changes made in gcc 4.6. To compile 2.9.10 you should install gcc44 and g++44, and the configure with polymake 2.10 should compile with gcc 4.6 without any errors (except maybe some warnings like from libreadline).

Hello, If you want to use the callable library from a shared module which is loaded on demand via dlopen you need to specify the RTLD_GLOBAL flag (at least for now). More details: polymake (and the same is true for perl) consists of one main library (libpolymake.so) and several different modules (e....

Hi, thanks for the report! You are correct, it should compute the total rank, as we cannot assume the rays to be orthogonal to the lineality space: int fanDim = rank(rays/linealitySpace); After changing that line and recompiling it, the client should produce a correct facet description of the fan.

On Ubuntu 11.04, I think the easiest option is to install the ubuntu packages gcc-4.4 and g++-4.4 and use this compiler with the following configure options CC=gcc-4.4 CXX=g++-4.4 Concerning the custom gcc: The problem is the "--enable-version-specific-runtime-libs" option together with th...

There is/was indeed a bug in the parsing of demangled c++ types with recent version of binutils (c++filt).
The attached patch should fix the problem with non-compiling wrappers.

It can be applied by running the following command in the polymake directory.

Seems to be a problem with the gcc you have built.
There should be a config.log in the directory where you ran those commands, can you attach it to a post?

The result was ~/bin/polymake/polymake-2.10/build.x86_64/external/nauty$ sh -c "CC=/usr/local/bin/gcc-4.4.6 ../../../external/nauty/configure; rm Makefile" loading cache ./config.cache checking host system type... configure: error: can not guess host type; you must specify one First, the ...

make -C build.i686/external/nauty helped to create nauty.h and whatever was supposed to be in build.i686/external/nauty. I don't know why they haven't been created automatically but at least this helped for you. However, I now get a new error message, which seems to be caused by javaview: polymake:...

If you do not have those nauty headers after running the make command i posted it seems that the nauty configuration fails, which i have never seen happen. Could you please change into build.xxx/external/nauty and run sh -c "CC=/usr/local/bin/gcc-4.4.6 ../../../external/nauty/configure; rm make...
