Hi I intended to upgrade r-cran-igraph[1] to the latest upstream version but I stumbled upon a strange issue where a #define statement seems to be ignored by the C prepocessor. At first I assumed that some printf format statement would be the cause which I tried to fix in a patch[2] but it seems that rather the
#define GRAPHML_NAMESPACE_URI "http://graphml.graphdrawing.org/xmlns" in the file src/foreign-graphml.c is ignored and makes the code fail. Any idea what might be wrong here? Kind regards Andreas.
