changing const int value in library header file

[aryan]

Hi,

I need to change the value of a const int variable defined in the
header file of a library. The variable is used to dynamically set size
of a char buffer within a class of the library. Its not used anywhere
else. It seems to work without recompiling atleast one application.
Would it work with other applications without recompiling?

thnx in advance

Depends on how it was defined (in a header or a separate cpp file),
toolchain, optimization flags details. Because a "const int" may be
completely compile time optimized out (that is where you use it the
compiler may directly put the value as of a "#define") instead of really
refer to some storage where the value is stored.
