Hi All,
I've just discovered Carrot (from slashdot) and have been playing around
with root and I've seemed to have struck trouble. I couldn't find a
pcre compatible class so I though I might try my hand at writing a
wrapper for pcre. I found a C++ class called pcre++ which looks very
close to what I need.
Just for starters I thought I might see if it compiled straight after
adding a ClassDef(TPcre,0) to the class definition (after changing the
class name to TPcre from Pcre (for "convention" ;-) ).
[I actually thought it might barf on the use of vector<int> etc but
after some testing in a test file it seemed to do what it was meant to :-) ]
Using the supplied pcre++ sample.cc I tried to compile it and I get
root [11] .x sample.C
Error: Too many '}' FILE:/usr/include/pcre.h LINE:107
If I do the naughty thing and drop down to root (user) and edit the file
and take out the
#ifdef __cplusplus
extern "C" {
#endif
and
#ifdef __cplusplus
}
#endif
and try to compile it I get:
root [12] .x sample.C
Error: Unexpected EOF G__fignorestream():3 FILE:/usr/include/pcre.h LINE:111
I got this error once before when I had forgotten to close a bracket
ie
void test()
{
TString s4("blah blah" //<--
//more stuff
}
but it's a normal system header, written by somebody who is infinitely
more able than me, so obviously there isn't (normall) any missing
bracket...
Is root missing something?
Event a straight..
rootcint pcre.C -c pcre++.h
Error: Too many '}' FILE:/usr/include/pcre.h LINE:107
Note: link requested for unknown class pcre FILE:G__auto17678LinkDef.h
LINE:7
Warning: Error occured during reading source files
Warning: Error occured during dictionary source generation
!!!Removing pcre.C pcre.h !!!
rootcint: error loading headers...
fails, yet the library compiles fine with g++
The smart question to ask first would be:
1. Has anyone written a pcre compatible class?
2. If not, anyone know why root might be failing with the brackets?
(I didn't change much in the normal distro of pcre++ so I'll just
provide the link to it instead of attaching it)

Thanks Everyone!
