Build error with gsoap

[Vogt Josef]

Hi list

Trying to build kannel gateway with gsoap (version 1.4.4) on RHEL7, but unfortunately I'm stuck with an error:
./bootstrap.sh
./configure --with-gsoap
make

...

It seems these references are not present:
$ nm -D /usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/libgsoapssl.so | grep soap_putheader
U soap_putheader

Any ideas what is going wrong here?
Thanks!
