Hello Sylvain, I took a look at the trace, it looks like g++ 7 is confused with the xml.h include ; as libxml2 is already protected with ifdef __cplusplus extern "C" you might just move the #include <xml.h> from XMLDocument.hxx:28 out of the extern "C".
Sorry about that but gcc-7 is not our target for official releases, Debian/Ubuntu/Fedora all ship gcc-8 with a more stable c++17 support. I could only help to debug issues on the conda side.
