Dear all, I tried to compiled one of the examples in nsapi folder. I got the following error:

[webdev] /opt/ns40sp6/plugins/nsapi/examples # gcc -I/opt/ns40sp6/plugins/inc>
In file included from /opt/ns40sp6/plugins/include/base/util.h:19,

What is wrong with the nsapi.h file? or gcc? or HPUX patching? Please advise.
