AW: [Ccrtp-devel] Problems building ccRtp for win32

[Steindl Christian]

hi john,

well, i gave up resolving this problem. i set the linker option force and ignored duplicate definition. that was just a workaround. if you have a better solution, please inform me. by the way, now i use the jrtplib2-7 ;-) which compiled failure free on first try on VC++6 and VC++7.

sincerely

chris

Hi Steindl,

 

Have you ever figured out this link problem with ccRTP?  I get the same errors.

I tried to build ccrtp-1.0pre2 with VS C++ 6.0.

For that i got following packages:
- commoncpp2-1.0.8
- libxml-2.5.4
- iconv-1.8

Unfortunately i had to do some tricks to get further:
1. there's no <cc++/pointer.h> file so i copied the file template/pointer.h
of the commoncpp package to its cc++ directory.
2. in file src/duplex.cpp(65) showed following error:
{
d:\ccrtp\ccrtp-1.0pre2\src\duplex.cpp(66) : error C2247: 'Error' not
accessible because 'ost::UDPSocket' uses 'public' to inherit from
'ost::Socket'
        d:\ccrtp\commoncpp2-1.0.7\include\cc++\socket.h(513) : see
declaration of 'Error'
d:\ccrtp\ccrtp-1.0pre2\src\duplex.cpp(66) : error C2247: 'Error' not
accessible because 'ost::UDPSocket' uses 'public' to inherit from
'ost::Socket'
        d:\ccrtp\commoncpp2-1.0.7\include\cc++\socket.h(513) : see
declaration of 'Error'
}
so i modified src/sha.cpp(554) from private to public inheritance!
3. project settings modified linking objects: replaced ccgnu2d.dll to
ccgnu2d.lib.

Now there's still a linking problem:
{

ccrtp1.dll - 7 error(s), 10 warning(s)

How come that thread, mutex etc. things are definied in control.obj ?

Thanks for any help building ccrtp on a win32-platform!
Sincerely
