vSphere SDK compilation fails with gSOAP and Power-PC compiler

[Saurabh20111014]

Hello VmWARE Gurus,

I am developing a vCenter application in C++ and using gSOAP to generate the C++ SDK from vCenter WSDL file.

SDK version: vSphere Web Services SDK 4.0

gSOAP version: gSOAP 2.8.3

powerpc-linux-g++: 3.4.6

gSOAP tools generate 2 cpp files:

-rw-r--r--   1 xxxx yyyy 52336045 Aug 25 22:23 soapC.cpp                      -> 52 MB

-rw-r--r--   1 xxxx yyyy  1033108 Aug 25 22:23 soapVimBindingProxy.cpp

When I try compiling these files and build my application, I get these linker errors:

powerpc-linux-g++ -g -O1 objs/vcenterClient.o objs/soapC.o objs/soapVimBindingProxy.o objs/stdsoap2.o  -lssl -lcrypto -o vcenterClient

2nd problem is while building the object for these files with -fPIC option. Compilation of soapC.cpp fails with this error:

I did some search on the google and realized that because of the huge file size (52 MB) this problem is happening. As a work around I tried to trim the vim.wsdl file and use only those operations/messages/request-response types in which I am interested.

By trimming the WSDL file, the file size got reduced by ~20% (42MB), it helped me linking the application successfully. But trimming the WSDL file manually is not a good idea considering to support future verions of WSDL.

Can somebody look into this and suggest a better solution to this problem?

Is there a way to get a WSDL as per our requirements instead of a single WSDL for all the operations?
