Move many third-party components' source codes from the src folder to a new folder called deps_src. The goal is to make the code structure clearer and easier to navigate.

Redefine qh_exit() as 'throw std::runtime_error("QH10003 ...")'
|
|
|
|
This file is not included in the Qhull builds.
|
|
|
|
qhull_r calls qh_exit() when qh_errexit() is not available. For example,
|
|
it calls qh_exit() if you linked the wrong qhull library.
|
|
|
|
The C++ interface avoids most of the calls to qh_exit().
|
|
|
|
If needed, include usermem_r-cpp.o before libqhullstatic_r.a. You may need to
|
|
override duplicate symbol errors (e.g. /FORCE:MULTIPLE for DevStudio). It
|
|
may produce a warning about throwing an error from C code.
