Let assume that I run a cmake with option `-DNETGEN_VERSION_GIT="v6.2.2204"` (or without this option at all) to avoid calling `git` which won't work when I've downloaded sources from GitHub as `.zip` file. If I try to compile sources and run it, it fails with error like: ``` libc++abi: terminating with uncaught exception of type std::invalid_argument: stoi: no conversion ``` after some digging I've discovered that `netgen_version.hpp` looks like: ``` #ifndef NETGEN_VERSION_HPP_INCLUDED #define NETGEN_VERSION_HPP_INCLUDED #define NETGEN_VERSION "6.2.0-v6.2.0.0-v6.2.0.0" #define NETGEN_VERSION_MAJOR 6 #define NETGEN_VERSION_MINOR 2 #define NETGEN_VERSION_PATCH 0 #define NETGEN_VERSION_TWEAK v6.2.0.0 #define NETGEN_VERSION_HASH "v6.2.0.0" #endif // NETGEN_VERSION_HPP_INCLUDED ``` This is happened because `string(REGEX REPLACE` copied original string to target and replaces it by regex. If regex doesn't match => it still copied an original value. So, this commit prevented this mess from happened.
Netgen mesh generator
NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement. Netgen 6.x supports scripting via a Python interface. Netgen is open source based on the LGPL license. It is available for Unix/Linux, Windows, and OSX.
