Compiling a simple Gsoap Service

I'm very new to gsoap and am attempting to follow this example.

Gsoap Example

I successfully installed Gsoap by downloading the binaries and using the following commands:

./configure --disable-ssl, make, sudo make install

I then created my .h file as shown in the example and compiled it using soapcpp2. I created a .cpp file as the example shows and attempted to compile.

When compiling, I am receiving compile errors in my automatically generated soapC.cpp class as well as my auto generated soapServer.cpp class. There are multiple errors and they are all approximately the same.

soapServer.cpp: undefined reference to 'ns_sub(soap*, double, double ,double*)'

I'm sure that this is a linker error. I am linking to the gsoap++ library that was created during the make process. Does anybody have any ideas? Thanks!

Ps. Here is the command that is being issued by eclipse:

g++ -o "GsoapTest" ./src/GsoapTest.o ./src/soapC.0 ./src/soapServer.o ./src/soapServerLib.o -lgsoap++

Solution

  • Are you sure that you have specified the service operation ns__sub correctly in step 1 of the example? The generated soapServer.cpp does not find a reference to ns_sub with one _ but I guess you have implemented it as in step 2 (ns__sub, with a double underscore).
