[Live-devel] calling Live555 libraries from a C app under Embedded Visual C++ 4.0

[Rodrigo Weymar]

Hi Bertram,


is your application written in C or C++ ? Were you able to mix C and C++
code and to declare C++ functions as extern "C" under EVC++ without using
#ifdef __cplusplus ?

If I try to use extern "C" under EVC++ without using #ifdef __cplusplus, I
get a

error C2059: syntax error : 'string'

as explained in http://www.kbalertz.com/kb_133070.aspx


regards,
Rodrigo
