Hi all, I've been using regex 3.20 with g++ 2.95.3 with no problems. We're in the process of moving towards g++ 3.1.1 (we have a library we need to use and it core dumps with 2.95.3 due to a bug in the stdc++ that goes with it in ofstream). So, I have g++ 3.1.1 working fine in redhat 6.2. I couldn't find the regex standalone library so I ended up downloading the whole boost suite (1_29_0) and I built only the regex++ library. I have one comment regarding this version (which I don't know what it is BTW. What's the version of regex++ in boost 1_29_0?, I guess it's 3.31). It seems that boost:cmatch doesn't work anymore when doing a regex_search, I ended up modifying boost:cmatch with boost::match_results<std::string::const_iterator>, I hope that's ok. I'm also having some trouble compiling some code but this is a problem with the new STL implementation that ships with g++ 3.1.1 (the v3 STL). I can't seem to find the solution, that's why I'm asking here, if anybody has any pointers I'll be very grateful. Look at what I get: commit.cpp: In function `void findSopInstances(IDB_HANDLE**, const std::vector<CommitSopInfo, std::allocator<CommitSopInfo> >&, std::vector<CommitSopInfo, std::allocator<CommitSopInfo> >&, std::vector<CommitSopInfo, std::allocator<CommitSopInfo> >&)': commit.cpp:737: conversion from `__gnu_cxx::__normal_iterator<const CommitSopInfo*, std::vector<CommitSopInfo, std::allocator<CommitSopInfo>

And the code it complains about is this: static void findSopInstances( IDB_HANDLE** idbHandle, const std::vector<CommitSopInfo>& rSopList, std::vector<CommitSopInfo>& rSuccesses, std::vector<CommitSopInfo>& rFailures ) { static const char * func = "(findSopInstances)"; // Iterate over list of SOP instances for ( std::vector<const CommitSopInfo>::iterator pos = rSopList.begin(); pos < rSopList.end(); pos++ ) { // Test whether we have this instance if ( haveSopInstance( idbHandle, pos ) ) { ...... Where haveSopInstance is defined as: static bool haveSopInstance( IDB_HANDLE** idbHandle, const CommitSopInfo* pSopInfo ) { now, this used to compile fine under g++2.95.3 with its stdc++. I don't see why it's having difficuly converting the interator to the CommitSopInfo*. Any ideas? thanks a lot, -Anibal

The separate regex version number has been removed it's just boost-1.29.0 now.
It seems that boost:cmatch doesn't work anymore when doing a regex_search, I ended up modifying boost:cmatch with boost::match_results<std::string::const_iterator>, I hope that's ok.
That's because you should only use cmatch with C strings (const char*), use boost::smatch with std::string's, that's what it's there for.
I'm also having some trouble compiling some code but this is a problem with the new STL implementation that ships with g++ 3.1.1 (the v3 STL). I can't seem to find the solution, that's why I'm asking here, if anybody has any pointers I'll be very grateful.
Look at what I get:
And the code it complains about is this:
Your code is buggy, see fixes below:
static void findSopInstances( IDB_HANDLE** idbHandle, const std::vector<CommitSopInfo>& rSopList, std::vector<CommitSopInfo>& rSuccesses, std::vector<CommitSopInfo>& rFailures ) { static const char * func = "(findSopInstances)";
// Iterate over list of SOP instances
// this line is buggy, you are trying to convert a const-iterator to an iterator, it should be: + for ( std::vector<const CommitSopInfo>::const_iterator pos = rSopList.begin();
for ( std::vector<const CommitSopInfo>::iterator pos =
rSopList.begin();
pos < rSopList.end(); pos++ ) {
// Test whether we have this instance
// bug: an iterator is not a pointer, this should be: + if ( haveSopInstance( idbHandle, &(*pos) ) )
if ( haveSopInstance( idbHandle, pos ) ) { ......
Where haveSopInstance is defined as:
static bool haveSopInstance( IDB_HANDLE** idbHandle, const CommitSopInfo* pSopInfo ) {
now, this used to compile fine under g++2.95.3 with its stdc++. I don't
see
why it's having difficuly converting the interator to the CommitSopInfo*.
