Emmake make errors when used for Modsecurity

[giantcroc]

Hi! When I use emmake make Modsecurity, I get the following errors.

Please help me with it. Thanks.

The first and biggest problem is see there is -I/usr/include -I/usr/include/libxml2 on the command line. Including those paths to your system headers is recipe for trouble. Emscripten builds should never use include files of libraries from the host OS and that is causing the C++ and C standard headers to get rather muddled.

ok,it works.thanks.:)

@giantcroc I'm facing the same issue building Modsecurity, and I don't get where should I remove the inclusion of these paths. Could you please give me any details on how you made it work? Thanks!
