I have no trouble building 1.35.0, as well as 1.36.0 on the timesys arm-gcc toolchain, both statically (link-static) as well as dynamically (.so, default option).
However, when I try to link a simple sample filesystem app:
#include <boost/filesystem.hpp>
#include <iostream>
namespace fs = boost::filesystem;
int main(int argc, char *argv[]) {
const char* fileName = argv[1];
std::cout << "file: " << fileName << " => " << fs::exists(fileName) << std::endl;
return 0;
}
I get the following linker error:
developer@eldp01:~/boost/test$ /opt/timesys/at91sam9263_ek/toolchain/bin/armv5l-timesys-linux-gnueabi-gcc
exists.cpp -o exists.exe -I ../boost_1_35_0/ -lboost_filesystem -lboost_system -lstdc++ -L .

collect2: ld returned 1 exit status
Does anyone know how I can get Boost to build for the gcc-arm toolchain?
