Stackoverflow parsing Eigen

jlaxson commented 4 years ago

Brief Description

When parsing a header that #includes <Eigen/Dense> or similar, the parse hanges for a long time before failing with a Stack overflow. I certainly don't need all (or any) of the Eigen functionality mapped but since it is failing in the parse stage, seems like applying TypeMap won't help.

OS: OS X Built from master with downloaded llvm

Used headers

#include <Eigen/Dense>

struct MyStruct {
  Eigen::Vector3f eigen_member_;
};

Used settings

mono bin/CppSharp.CLI.exe testheader.h -I /usr/local/include/eigen --debug Target: Clang

@jlaxson we know about this bug, in fact, it's been reported with the very same header. Out free time is limited at present but you can always try contacting our support.

Are there any updates on that issue ? I am facing the same problem and I don't really see any workaround for now : |

@brunnerant Wish I had a better answer to tell you but the fact is our time to work on these kind of fixes is extremely limited, given all the other issues and improvements we could be doing.

The fastest way to get this over the line is to get in contact with either me or @josetr and sponsor the fix, we offer pretty fair rates for this kind of support work and will gladly help you with what you need.
