linux下如何使用SGI STL？

[hz129]

我在linux9(G++3.2.2)下，默认使用的标准STL库，我想使用SGI STL库，请问该如何设置？

[victor_cui]

可以这样做，首先当然是要包含SGI的头文件，并引用其中的模板类，编译是在makefile中包含-I 相应头文件路径，当然如果你已经在包含的时候写了全路经可以声调这一选项。然后连接的时候指定库 -L （lib）即可，如果定义了库路径的环境，可以直接输入库文件名，如果没有的话需要制定全路经

[hz129]

标准STL头文件目录：/usr/include/c++/3.2.2
SGI STL头文件目录：/usr/include/g++-3
但我不知道lib的目录在哪里，我现在用
g++ -I/usr/include/g++-3 xxx.cpp -o xxx.out
出现了一堆的错误：（

是编译期错误还是连接错误？

源程序如下：
// file : 4slist-test.cpp
#include <slist>
#include <iostream>
#include <algorithm>
using namespace std;

int main() {
int i;
slist<int> islist;
cout << "size=" << islist.size() << endl; // size=0

islist.push_front(9);
islist.push_front(1);
islist.push_front(2);
islist.push_front(3);
islist.push_front(4);
cout << "size=" << islist.size() << endl; // size=5

slist<int>::iterator ite = islist.begin();
slist<int>::iterator ite2 = islist.end();
for(; ite != ite2; ++ite)
cout << *ite << ' ';
cout << endl; // 4 3 2 1 9

ite = find(islist.begin(), islist.end(), 1);
if (ite != 0)
islist.insert(ite, 99);

cout << "size=" << islist.size() << endl; // size=6
cout << *ite << endl; // 1

ite = islist.begin();
ite2 = islist.end();
for(; ite != ite2; ++ite)
cout << *ite << ' ';
cout << endl; // 4 3 2 99 1 9

ite = find(islist.begin(), islist.end(), 3);
if (ite != 0)
cout << *(islist.erase(ite)) << endl; // 2

ite = islist.begin();
ite2 = islist.end();
for(; ite != ite2; ++ite)
cout << *ite << ' ';
cout << endl; // 4 2 99 1 9
}

g++ -I/usr/include/g++-3 xxx.cpp -o xxx.out

你既然不使用stl库，为什么还是用它的名字空间啊，还有就是要需要声明使用SGI的名字空间

[victor_cui]

std

[hz129]

我看了一下slist的代码，其中有如下一行：
...
__STL_BEGIN_NAMESPACE
...

在stl_config.h中有此宏的定义：
# define __STL_BEGIN_NAMESPACE namespace std {
我的GCC版本>2.8，所以此宏是有效的

那么我还是应该使用std才对吧

[sevencat]

??不是说GCC用的就是SGI的STL吗？

[hz129]

终于搞定了，原来G++3.2.2使用的还是SGI STL，但是它把非标准的部分放在了ext子目录下，只要改为：

#include <ext/slist>
#include <iostream>
#include <algorithm>
using namespace std;
using namespace __gnu_cxx;

就行了。
