加大对GCC臂工具链C ++库 [英] Boost C++ libraries for gcc-arm toolchain
问题描述
我对TimeSys的手臂gcc工具没有烦恼建设1.35.0,以及1.36.0,无论是静态(链接静态)和动态(。所以,默认选项)。
然而,当我尝试链接一个简单的示例文件系统的应用程序:
的#include<升压/ filesystem.hpp>
#包括LT&;的iostream>命名空间FS =的boost ::文件系统;INT主(INT ARGC,CHAR *的argv []){
为const char *文件名=的argv [1];
性病::法院LT&;< 文件:<<文件名<< =><< FS ::存在(文件名)<<的std :: ENDL;
返回0;
}
我得到下面的连接错误:

有谁知道我怎样才能推动建立海合会臂工具链?
您需要在文件中添加boost_1_35_0 /升压/配置/ user.hpp中
的#define BOOST_SP_USE_PTHREADS
顺便说一句,你需要设置GCC工具链中的文件'boost_1_35_0 /工具/建设/ V2 /用户config.jam中到:
使用gcc

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 . /tmp/ccex3NGb.o: In function `boost::detail::atomic_decrement(int*)': exists.cpp:(.text._ZN5boost6detail16atomic_decrementEPi[boost::detail::atomic_decrement(int*)]+0x1c): undefined reference to `__sync_fetch_and_add_4' /tmp/ccex3NGb.o: In function `boost::detail::atomic_increment(int*)': exists.cpp:(.text._ZN5boost6detail16atomic_incrementEPi[boost::detail::atomic_increment(int*)]+0x1c): undefined reference to `__sync_fetch_and_add_4' collect2: ld returned 1 exit status
Does anyone know how I can get Boost to build for the gcc-arm toolchain?
解决方案You need to add in file 'boost_1_35_0/boost/config/user.hpp':
#define BOOST_SP_USE_PTHREADS
btw, you need to set the gcc tool-chain in file 'boost_1_35_0/tools/build/v2/user-config.jam' to:
using gcc : arm : /opt/timesys/at91sam9263_ek/toolchain/bin/armv5l-timesys-linux-gnueabi-gcc ;
This will solve the problem of linking now.
