My ubuntu is 10.04. boost was installed from apt-get.
I compiled the following code. But the library is not available to link. Would you please let me know how what link option I should use?
$ cat main.cpp #include
#include <iostream> #include <string> int main() { boost::filesystem::path path1("/tmp/dir1/test1.c "); boost::filesystem::path path2("/tmp/dir1/.test1.profile"); std::string result1 = boost::filesystem::basename (path1); std::string result2 = boost::filesystem::basename (path2); std::cout << result1 << std::endl; std::cout << result2 << std::endl; return 0; }
$g++ -o main.exe main.cpp /tmp/ccSvyGYq.o: In function `__static_initialization_and_destruction_0(int, int)': main.cpp:(.text+0x15d): undefined reference to `boost::system::get_system_category()' main.cpp:(.text+0x169): undefined reference to `boost::system::get_generic_category()' main.cpp:(.text+0x175): undefined reference to `boost::system::get_generic_category()' main.cpp:(.text+0x181): undefined reference to `boost::system::get_generic_category()' main.cpp:(.text+0x18d): undefined reference to `boost::system::get_system_category()' collect2: ld returned 1 exit status make: *** [main.exe] Error 1
In addition to the boost_filesystem lib, you also need to link against the boost_system lib. I believe this should solve your problem. Regards, Mostafa
