vfgen fails to build as it's looking for vf_help_text.cpp #5

Closed sdwfrost closed 3 years ago

sdwfrost commented 4 years ago

The package fails to build as vf_help_text.o is listed in OBJ_FILES but there isn't a corresponding .cpp file in vfgen/src. Removing vf_help_text.o from OBJ_FILES allows compilation to continue, however, I then get the following error:

vfgen.o: In function `main':
vfgen.cpp:(.text.startup+0x3783): undefined reference to `VectorField::PrintBoostOdeint(std::map<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::less<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >)'
collect2: error: ld returned 1 exit status
Makefile.vfgen:53: recipe for target 'vfgen' failed

This is on Ubuntu 18.04.

@sdwfrost, thanks for reporting the problem. Back in May I made some changes to how the text for the help messages was stored. I updated CMakeLists.txt to deal with the change (so building with CMake should work), but I neglected to updated Makefile.vfgen. I'll take a closer look this weekend.

Thanks @WarrenWeckesser! I have an example of using vfgen in my online textbook of epidemiological models Epirecipes, so fixing would be great as I'm more of a configure/make person than CMake...

@sdwfrost, I just pushed an update to the Makefiles. If you are building from the github source, grab the latest version and let me know if you have any problems building vfgen.
