On compiling with g++   parse.cpp -dynamic /usr/lib/libocc.so 

(1) Your g++ is not interpretting '-dynamic' as an option, it reads '-dy -n -a -m -i -c'


(2) Your are not getting the static linking right -- you need to be linking with .a or .o file. Look whether you have libocc.a, if not, build it and link against it. Make sure to build it with -g for debugging symbols.

the program runs correctly. However it prints out a couple of warnings:
g++   parse.cpp -dynamic /usr/lib/libocc.so cc1plus: warning: unrecognized gcc debugging option: ncc1plus: warning: unrecognized gcc debugging option: m
cc1plus: warning: unrecognized gcc debugging option: icc1plus: warning: unrecognized gcc debugging option: cparse.cpp:1: warning: The C++ parser does not support -dy, option ignored

Any idea why these are coming up?

I noticed that ubuntu has a package for clang that functions perfectly. By reading the documentation , i deduce that it is possible to get a Ptree of a express specified as a string. 


however i ran into a bit of a problem. While occ works fine if i call it via the command line , but when i include the headers , it gives me a segmentation fault.


Try to reproduce with static linking, a wild gues would be you are running into some problems with dynamic linking.

My code is :
#include<iostream>

#include<openc++/parser/PtreeArray.h>
int main()

{    std::cout<<"i am here"<<std::endl;     Opencxx::PtreeArray a;

}
and the command i used to compile it is:

g++ -g  parse.cpp -shared /usr/lib/libocc.so
however the line i am here is not printed. and the seg fault occurs before that. The stack trace is :


(gdb) rStarting program: /home/kartikeya/temp/a.out 


Program received signal SIGSEGV, Segmentation fault.0x00000001 in ?? ()(gdb) bt

#0  0x00000001 in ?? ()
Please point out the mistake.



Thanks in advance,
Harsh Gupta

What Every C/C++ and Fortran developer Should Know!

Read this article and learn how Intel has extended the reach of its

next-generation tools to help Windows* and Linux* C/C++ and Fortran
