gsoap++ linking error

Question

I wrote a soap-client with gsoap++ library. once i compiled this one as a stand-alone test app it was compiled fine, but when i try to compile these classes including in my project i get a lot of linking errors:

../common/UserGausClient/UserGausClient.o: In function `GAUS::SSLInit()':

and so on. In Codeblocks it linking fined... Here is my Makefile:

I linked against all necessary libraries (-lgsoapssl++ -lssl -lcrypto) and I checked out requesting functions in these ones:

$ nm /usr/lib/libgsoapssl++.a | grep soap_begin_count
00018da0 T soap_begin_count

and there are in libraries. so, what a problem?

Answer 1

One possible reason for this is the order that the libraries are specified to the linker, some linkers require that the libarary containing the definition of a function appears after the object or library that requires it. Try re-arranging the library definitions so that this is the case here and check your linkers documentaion to see if it requires this.
