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

[Bertram Junker]

Hi Rodrigo,

i have written an SIP phone with RTP Stack from LIVE555 for Pocket PC / 
Windows CE with EVC++ 4.0. Unfortunately I'm not able to solve your 
problem but I can ensure you, that LIVE555 works fine under EVC++. 
Further, I remember me fine, I have not set up any preprocessor directive.

Best regards,

    Bertram
