AFAICT, you only have to touch the following locations: * apps/graph/src/Makefile.inc: Remove the references to nauty, try this instead: graph_compare$O : ExtraCXXFLAGS = -I/usr/include/bliss LIBS += -lbliss (assuming a systemwide package of bliss). * apps/graph/src/graph_compare.h, apps/graph/src/graph_compare.cc: This is the actual code using nauty. There are 2 layers of abstraction: a public API wraps the NautyGraph class declared in the header, which itself is actually implemented in the .cc file. With those abstractions, it should be possible to replace this with an implementation using bliss without touching any other code file. * apps/graph/rules/comparing.rules: I'm not sure how CREDIT is processed, but I think you need to change: CREDIT nauty Computation of automorphism groups of graphs. Copyright by Brendan McKay. http://cs.anu.edu.au/~bdm/nauty/ to: CREDIT bliss Computation of automorphism groups of graphs. Copyright by Tommi Junttila and Petteri Kaski. http://www.tcs.hut.fi/Software/bliss/ * apps/polytope/rules/polytope_properties.rules: Again, I'm not sure how CREDIT is processed, but you should probably change "CREDIT nauty" to "CREDIT bliss". * ext_lib/nauty: rm -rf the whole directory from the source tarball * external/nauty: rm -rf the whole directory from the source tarball You should also unbundle cdd and lrs (i.e. use separate packages for those) and check that you don't have GPL version conflicts (v2 only vs. v3 only). (FYI, bliss is GPLv3.) Kevin Kofler -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
