anonymous namespace issue

[amigo421]

(not sure that is a problem of the lib).
I was writing an own project with a lot of headers (with logic) and added TEST_CASEs into each one. and was debugging/testing these ones individually. But after merging all headers into one project I faced with a number of similar issue which refer to TEST_CASE declaration in various modules in my project
(just for sure, my code works as designed and removing a part of TEST_CASEs solve the problem ), I'm also confirming that all TEST_CASEs compiled and work correctly in case of including into the project without other headers (looks like a conflict). the errors looks like these ones:

c:\dev\workspace\algolist\src\algolist.hpp(143): error C2374: '`anonymous-namespace'::autoRegistrar143': redefinition; multiple initialization
c:\dev\workspace\algolist\src\mfactory.hpp(143): note: see declaration of '`anonymous-namespace'::autoRegistrar143'
c:\dev\workspace\algolist\src\algolist.hpp(143): error C2084: function 'void ____C_A_T_C_H____T_E_S_T____143(void)' already has a body
c:\dev\workspace\algolist\src\mfactory.hpp(143): note: see previous definition of '____C_A_T_C_H____T_E_S_T____143'

#define CATCH_INTERNAL_LINEINFO ::Catch::SourceLineInfo( FILE, static_caststd::size_t( LINE ) )

The unique name don't have to use line number, otherwise when including other files you'll get this error

If possible (the compiler supports it), we now use __COUNTER__ to generate the unique name. Can you please check whether current single-include release still causes this error for you?

hi mate,
is the problem still actual?
from those times, I changed my style and now never write a tests in the same header with a logic.
so that is a no issue for me yet, but I can try to do this , just to assist with a testing

[horenmar]

@amigo421 It should be fixed, but testing is always welcome.

[philsquared]

Any feedback would be welcome. However please note that it does depend on whether we detect compiler support for __COUNTER__.

[amigo421]

if you treat this as solved, I won't test this right now , just will report this in case Iwill have faced with this again (i'm mostly using vc++ which supports __COUNTER__)

p.s. congrats-glad to see that you now work with jetbrains
