I run boost on Windows but the first things to check should be similar: 1. Does apt-get get the compiled version of boost or just get the sources ? Are the compiled shared and lib files there ? 2. In case the files are there, is the directory included in the search path for the linker ? Best regards, Mau. 2010/6/14 Peng Yu <pengyu.ut@gmail.com>:

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 <boost/filesystem.hpp> #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
