It seems this is a subtle issue in the interplay between ecls and boehm-gc.
The GC initializes as soon as a thread is started, but ecls seems to assume
it manually needs to initialize. This generates the error, since the
initialization can be done only once. To further
Hello,
Right now, no. My graphs do not have parallel edges.
You are right it is horrible to provide an efficient implementation for
labeled subgraph extractions. Just one idea makes my mind busy. I believe
what makes the function subgraph does not work for labeled graphs is
isomorphic
Hello,
I am not sure that I understood your message very well. Are you saying
that one way to achieve what you do would be to call the current
subgraph_search methods, and to *filter* among its results those
which are actually *equal* (considering edge labels) to the graph you
are looking for?
