[Ccrtp-devel] undefined reference

[Uwe Pries]

hello list,

i just compiled the libccrtp on my redhat 9.0.
and tried to compile the demos/examples with following command:
g++ -lccrtp1 -lpthread -o rtphello rtphello.cpp

the linker tells me:
/usr/local/lib/libccrtp1.so: undefined reference to `vtable for
ost::MD5Digest'
/usr/local/lib/libccrtp1.so: undefined reference to
`ost::MD5Digest::getDigest(unsigned char*)'
/usr/local/lib/libccrtp1.so: undefined reference to
`ost::MD5Digest::MD5Digest[in-charge]()'
/usr/local/lib/libccrtp1.so: undefined reference to
`ost::MD5Digest::putDigest(unsigned char const*, unsigned)'
/usr/local/lib/libccrtp1.so: undefined reference to `VTT for ost::MD5Digest'
collect2: ld returned 1 exit status

end exits...

what am I dong wrong?
do I need another lib?
or include another lib?
...

thanks for your help
best regards
e-voc
