编译安装
bash bootstrap.sh echo $? ./b2 echo $? sudo ./b2 install --prefix=/tmp/haha #/tmp/haha是我建立的目录 echo $? chunli@linux:~$ ll /tmp/haha/ total 8.0K drwxr-xr-x 3 root root 4.0K Oct 18 20:58 include drwxr-xr-x 2 root root 4.0K Oct 18 20:59 lib chunli@linux:~$ du -sh /tmp/haha/ 184M /tmp/haha/ chunli@linux:~$
写个测试程序:
root@linux:/tmp# cat main.cpp
#include <boost/lexical_cast.hpp>
#include <iostream>
using namespace std;
int main()
{
using boost::lexical_cast;
int a=lexical_cast<int>("123");
double b=lexical_cast<double>("123.0123456789");
string s0=lexical_cast<string>(a);
string s1=lexical_cast<string>(b);
cout<<"number: "<<a<<" "<<b<<endl;
cout<<"string: "<<s0<<" "<<s1<<endl;
int c=0;
try{
c=lexical_cast<int>("abcd");
}
catch(boost::bad_lexical_cast& e){
cout<<e.what()<<endl;
}
cout << "Hello \n";
return 0;
}
root@linux:/tmp# g++ main.cpp && ./a.out
number: 123 123.012
string: 123 123.0123456789
bad lexical cast: source type value could not be interpreted as target
Hello
root@linux:/tmp#编译报错:
chunli@ubuntu14:/tmp$ g++ main.cpp main.cpp:1:39: fatal error: boost/lexical_cast.hpp: No such file or directory #include <boost/lexical_cast.hpp> ^ compilation terminated.
解决办法:指定头文件
chunli@ubuntu14:/tmp$ g++ main.cpp -I haha/include/ chunli@ubuntu14:/tmp$ ./a.out number: 123 123.012 string: 123 123.0123456789 bad lexical cast: source type value could not be interpreted as target Hello chunli@ubuntu14:/tmp$
永久的解决办法,放到系统的路径下
chunli@ubuntu14:/tmp$ sudo mv haha/include/* /usr/include/ chunli@ubuntu14:/tmp$ sudo mv haha/lib/ /usr/lib/ chunli@ubuntu14:/tmp$ g++ main.cpp && ./a.out number: 123 123.012 string: 123 123.0123456789 bad lexical cast: source type value could not be interpreted as target Hello chunli@ubuntu14:/tmp$
