Hi Kuba,
for whatever reason I get the message
selection.cpp:675:10: error: ‘for_each’ is not a member of ‘std’
this is what make executes:
g++ -c -m64 -pipe -O2 -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2
-fstack-protector -funwind-tables -fasynchronous-unwind-tables -g
-Wall -W -D_REENTRANT -DRESOURCES_DIR=\"/usr/lib/xcircuit-3.7\"

-I/usr/include/QtGui -I/usr/include -I. -o selection.o selection.cpp
I thought maybe I am missing a development library or two so I found a
snippet using for_each to test:
// for_each example
#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
void myfunction (int i) {
cout << " " << i;
}
struct myclass {
void operator() (int i) {cout << " " << i;}
} myobject;
int main () {
vector<int> myvector;
myvector.push_back(10);
myvector.push_back(20);
myvector.push_back(30);
cout << "myvector contains:";
for_each (myvector.begin(), myvector.end(), myfunction);
// or:
cout << "\nmyvector contains:";
for_each (myvector.begin(), myvector.end(), myobject);
cout << endl;
return 0;
}
and that one works perfectly with g++, so I don't think I am missing
any library. I have never used for_each before so I don't know what I
am missing out. On pure trial-and-error I included a
#include <algorithm>
to selection.cpp and then at least that file compiled.
Kind regards,
