Hi!
I am using xcode 3.1 and I am trying to build a 32bit boost test
application. I have done this successfully on windows (Header only libraries
are working fine in xcode). These are the steps I followed:
1) ./configure
--with-libraries=date_time,filesystem,iostreams,program_options,serialization,system,thread
2) sudo make install
I dont get any error and the installation says it updated all targets.
3) Next, I create a simple thread application to test:
#include
#include <iostream>
void hello()
{
std::cout <<"Hello world, I'm a thread!"<< std::endl;
}
int main(int argc, char* argv[])
{
boost::thread myThread(&hello);
myThread.join();
return 0;
}
4) I go to project > edit project settings and add the following two paths
in the search path section:
/usr/local/lib (for library path) and
/usr/local/include/boost-1_37 for header path.
BOOST_ROOT is set as /Users/Framebuffer/boost_1_37_0
I have even tried to change it to /usr/local/ but the errors persist
I have examined the two folders and the libraries and headers are indeed
present there (for eg, libboost_thread-xgcc40-mt-1_37.dylib is in the lib
folder)
5) When I try to compile either the debug or release version, I get errors.
Here are the errors for debug build results:

Both files libboost_thread-xgcc40-mt-1_37.dylib and
libboost_thread-xgcc40-mt-1_37.a are present in /usr/local/lib
What am I missing? Any help will be appreciated.
ALSO, I tried to compile and run a date time example, and it seems to be
working fine. (Both debug and release) Below is the code that is working.
Other libraries like filesystem etc and not working though.
#include "boost/date_time/gregorian/gregorian.hpp"
#include "boost/date_time/posix_time/posix_time.hpp"
#include <iostream>
using namespace boost::gregorian;
using namespace boost::posix_time;
int main()
{
date d(2002,Feb,1); //an arbitrary date
ptime t1(d, hours(5)+milliseconds(100)); //date + time of day offset
ptime t2 = t1 - minutes(4)+seconds(2);
ptime now = second_clock::local_time(); //use the clock
date today = now.date(); //Get the date part out of the time
date tomorrow = today + date_duration(1);
ptime tomorrow_start(tomorrow); //midnight
//input streaming
std::stringstream ss("2004-Jan-1 05:21:33.20");
ss >> t2;
//starting at current time iterator adds by one hour
time_iterator titr(now,hours(1));
for (; titr < tomorrow_start; ++titr)
{
std::cout << (*titr) << std::endl;
}
return 0;
}
I found this tutorial :
http://soulstorm-creations.com/PROJECT_SOULSTORM_2_0/index.php?option=com_content&view=article&id=47:xcode-and-boost-liraries-a-setup-tutorial-article&catid=18:programming-articles&Itemid=39
and I tried his method and its giving the same 9 errors out of the box.
Thanks,
fb.
