I needed to use the openc++ parser for an application that i was developing. The platform for use is Ubuntu Linux 10.04. Basically what i need is a c++ parser and openc++ seemed to be a worthy candidate. however on running the wrapper example i get the following error, /usr/include/wchar.h:220: parse error before `"wcschr"' /usr/include/stdlib.h:525: parse error before `"at_quick_exit"' /usr/include/c++/4.4/bits/cpp_type_traits.h:99: parse error before `>' /usr/include/c++/4.4/bits/cpp_type_traits.h:104: parse error before `template' /usr/include/c++/4.4/ext/type_traits.h:37: parse error before `__gnu_cxx' /usr/include/c++/4.4/ext/type_traits.h:174: parse error before `+' /usr/include/c++/4.4/ext/type_traits.h:186: parse error before `+' /usr/include/c++/4.4/ext/type_traits.h:199: parse error before `+' /usr/include/c++/4.4/ext/numeric_traits.h:37: parse error before `__gnu_cxx' /usr/include/c++/4.4/ext/numeric_traits.h:63: parse error before `template' occ: too many errors Please suggest what i can do to correct this error. Alternatively if you could suggest some other way of developing a wrapper for openc++, where i could get the parse tree of a cpp file programmatically then it would be a great help. I tried printing out the parse tree using the -s arguement and by supressing preprocessing then it works fine (on the terminal). Harsh Gupta |

AFAIK, you may either use an older compiler. I'd guess gcc 3.3 would work. Or you may update the openc++ parser so it can parse the new C++ implemented by gcc 4.4. -- __Pascal Bourguignon__ http://www.informatimago.com/ A bad day in () is better than a good day in {}. |

Hi Harsh, OpenC++ maitenance ceased around gcc version 3.x (perhaps 3.3 as Pascal points out). OpenC++ does not handle certain template constructs that are present in the standard headers of the library distributed with gcc beyond that version -- most likely this is where your problem comes from. Going back to earlier gcc seems like the only quick solution.

hi Greg, I dont need to parse the headers, i just need to parse the programs written in c plus plus. My application just requires a parse tree of the c plus plus file. Is it possible to build a wrapper for the parser in openc++? Please share some pointers. Harsh Gupta Date: Sat, 21 May 2011 13:24:50 +0200 Subject: Re: [Opencxx-users] compiling on linux.

The OpenC++ parser has some sever limitations, which have become quite apparent as changes and improvements have been applied to libstdc++, making the two incompatible.

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.
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,

Try to reproduce with static linking, a wild gues would be you are running

On compiling with g++ parse.cpp -dynamic /usr/lib/libocc.so
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: mcc1plus: 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?

(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.

Thanks a ton greg. Removing the dynamic option solved the problem..

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.
Greg
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,
