我正在尝试通过串口访问外部设备,并希望使用Boost.Asio来实现此建议.我为MinGw构建了boost库并成功编译了正则表达式示例.
但是如果我包含来自Boost.Asio的内容,我在编译代码时遇到问题:
#include <boost/asio/serial_port.hpp>
int main() {
return 0;
}
g++ -D _WIN32_WINNT=0x0501 -O0 -g3 -Wall -c -fmessage-length=0 -osrc\SerialPortTest.o ..\src\SerialPortTest.cpp
g++ -LC:\boost-libs\boost\bin.v2\libs\thread\build\gcc-mingw-4.5.2\release\link-static\threading-multi -LC:\boost-libs\boost\bin.v2\libs\system\build\gcc-mingw-4.5.2\release\link-static\threading-multi -oSerialPortTest.exe src\SerialPortTest.o -lboost_thread-mgw45-mt-1_48 -lboost_system-mgw45-mt-1_48

collect2: ld returned 1 exit status
对我来说,它似乎是一个链接问题,但我不明白.
