5 years ago Add the -DUSE_TREETRACKER=OFF flag to the cmake command. I should probably make that the default.

5 years ago Yes, I tried that before but I get another problem when I run the make command at approximately 97% in SympyDummies.cc, because that file depends on treetracker.h. I get the following error:
[ 1%] Building CXX object CMakeFiles/cadabra2++objects.dir/SympyDummy.cc.o /home/tomaco/Tomaco/Hobbies/Programacion/Cadabra/cadabra2/c++lib/SympyDummy.cc:7:10: fatal error: treetracker.h: No such file or directory

Then, I tried commenting #include "treetracker.h" inside SympyDummies but it did not work yet I get:

5 years ago Thank you so much, it works! I am having a few troubles with the include path but I guess I will figure it out on my own. Regarding my interest in cadabra2 as a C++ library, nowadays I am trying to make an "all_contractions" program to take a few objects with particular indices and symmetries and get the most general combination (contraction) of them. If I am not mistaken, I think that you had a version of that program on cadabra1, but I do not find it in cadabra 2. These days I am trying to make a humble version of the program using a mixed between python and cadabra2 tools inside jupyter notebook, but now that you solved the C++library problem I guess that it would be much more easier from the source code of cadabra2, is it true? I would appreciate every advice you can give me regarding this program that I would like to build!
Best wishes, Tomas.

5 years ago The all_contractions algorithm is no longer present in cadabra2 because it was only incompletely implemented in cadabra1. This problem is quite a bit more tricky than you might think. There are two issues which cadabra1 did not solve:
Dimension dependent identities, which mean that not all monomials which are independent in arbitrary dimensions are independent in low dimensions (there is an example of such a thing in the hep-th cadabra paper). As a consequence, there situations in which the list of contractions which Cadabra returns is not independent.
Contractions which involve not just the metric but also the totally anti-symmetric epsilon tensor; these are singlets and thus count towards the group-theoretical 'number of singlets', but Cadabra did not generate them. As a consequence, there are again situations in which the list of contractions which Cadabra returns is not independent.
This may not matter for your particular application, but it is good to keep this in mind.
We are at the moment implementing new algorithms which handle the first problem correctly, but have not yet tackled the second one. If you are interested I am happy to discuss this with you though. Email me privately.
Hello there. I already have cadabra2 inside jupyter notebook but I'd like to have the chance to use it as a C++ library from time to time. However, when I try to build the library from source following the GitHub instructions I get the following error:
cmake .. -- The C compiler identification is GNU 7.3.0 -- The CXX compiler identification is GNU 7.3.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- CMake version = 3.13.4 -- Found gmp /usr/lib/x86_64-linux-gnu/libgmp.so -- Found gmpxx /usr/lib/x86_64-linux-gnu/libgmpxx.so -- Found PCRE: /usr/lib/x86_64-linux-gnu/libpcrecpp.so

I guess that I don't have that header... What should I do?
