If you want to statically link this program against a non-dll .a file, you must |
23 |
|
define PCRE_STATIC before including pcre.h, otherwise the pcre_malloc() and |
24 |
|
pcre_free() exported functions will be declared __declspec(dllimport), with |
25 |
|
unwanted results. So in this environment, uncomment the following line. */ |
