Re: [Mingw-users] unknown error

[Christoph H. <sha...@ar...>]

Hi,
thank you the compile log is now only five lines :)

I used your tips with the new and std:: and I also found out that I 
didn't need #include<vector> in the main.cpp.
But still the allocation fails. It says something like function call in 
constant expression. I tried to read the values in temporary variables, 
but it say again that t0,t1 (the temp vars) cannot appear as constant 
expression.

Any workarounds for this?

Regards,
   Christoph

The problem:
  int * Plasma;
  
Plasma=new(std::nothrow)int[Config.getInt("PlasmaWidth")][Config.getInt("PlasmaHeight")];

The current compile log:
  E:\files\programmierung\arbeitsproben\plasmagen\src\main.cpp In 
function `int SDL_main(int, char**)':
  189 E:\files\programmierung\arbeitsproben\plasmagen\src\main.cpp 
`Config' cannot appear in a constant-expression
  189 E:\files\programmierung\arbeitsproben\plasmagen\src\main.cpp `.' 
cannot appear in a constant-expression
  189 E:\files\programmierung\arbeitsproben\plasmagen\src\main.cpp a 
function call cannot appear in a constant-expression
  E:\files\programmierung\arbeitsproben\plasmagen\src\Makefile.win
