uftrace for POCO - namhyung/uftrace GitHub Wiki
Getting Started With The POCO C++ Libraries
1. download prerequisites
$ sudo apt-get install openssl libssl-dev
$ sudo apt-get install libiodbc2 libiodbc2-dev
2. download poco
$ git clone https://github.com/pocoproject/poco.git
$ cd poco
$ git checkout poco-1.7.5-release
3. configure and build poco with -pg
$ mkdir cmake_build
$ cd cmake_build
$ cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/usr \
-DCMAKE_C_FLAGS="-g -pg -fno-omit-frame-pointer" \
-DCMAKE_CXX_FLAGS="-g -pg -fno-omit-frame-pointer"
$ make
$ make install
4. test program
$ cat poco-test.cpp
#include "Poco/BasicEvent.h"
#include "Poco/Delegate.h"
#include <iostream>
using Poco::BasicEvent;
using Poco::Delegate;
class Source
{
public:
BasicEvent<int> theEvent;
void fireEvent(int n)
{
theEvent(this, n);
}
};
class Target
{
public:
void onEvent(const void* pSender, int& arg)
{
std::cout << "onEvent: " << arg << std::endl;
}
};
int main(int argc, char** argv)
{
Source source;
Target target;
source.theEvent += Delegate<Target, int>(
&target, &Target::onEvent);
source.fireEvent(42);
source.theEvent -= Delegate<Target, int>(
&target, &Target::onEvent);
return 0;
}5. compile a poco test program
$ g++ -pg -g -I$HOME/usr/include poco-test.cpp -L$HOME/usr/lib -lPocoFoundation
$ ./a.out
onEvent: 42
6. run uftrace record and replay
$ uftrace -D 2 ./a.out
onEvent: 42
