C++: What is the appropriate use for the std::logic_error exception?


C++: What is the appropriate use for the std::logic_error exception?

I think the issue was by ths following , logic_error is the base for these exceptions: domain_error, invalid_argument, length_error, out_of_range.
Those are all logical errors: Somethings wrong with the input such that the output would be illogical. So I'd say you usually don't need to use it directly, since those four cover any logic errors I can think of. But those give you an idea of what the category is.

I wish did fix the issue. Edit from the edited question, it now became clear that CMain.exe is not being executed, but rather being built.
The same story applies (see below), but I'll post more relevant hints once there is more new information. Hang on
code :
getenv(...)
 std::string s = getenv("SOMEVAR");   // WRONG!
 const char* raw = getenv("SOMEVAR");
 std::string s = raw?raw:"";         // RIGHT!

To fix the issue you can do
[W]hy is the inheritance [w.r.t. exceptions] in the standard library not virtual?
Why is there std::logic_error?

To fix this issue Consider this code snippet, part of a million of lines of code product:
std::logic_error::logic_error undefined

std::logic_error::logic_error undefined

will be helpful for those in need Judging from undefined reference to std::logic_error::logic_error linker message it looks like you are linking with gcc. You need to link C++ applications with g++. Or link with gcc and add -lstdc++ to the linker command line.

I hope this helps you . The C++ standard says this about logic_error (§22.2.2) :
