Boost.Asio 链接错误
我正在尝试通过串行端口访问外部设备,并希望使用 Boost.Asio 来实现此建议。 我已经为 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,我在编译代码时就会遇到问题:
#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,这似乎是一个链接问题,但我不明白。
I'm trying access an extern device via a serial port and want to use Boost.Asio for this propose.
I have build the boost libraries for MinGw and compiled the regex example successful.
But I have problems to compile my code if I include something from Boost.Asio:
#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
src\SerialPortTest.o: In function `ZN5boost4asio6detail17winsock_init_base7startupERNS2_4dataEhh':

collect2: ld returned 1 exit status
For me it seems to be a linking problem, but I don't get it.

添加 -lws2_32 标志以链接到 WinSockets 库。
另外,这可能有用: MinGW 链接器错误:winsock
Add -lws2_32 flag to link against WinSockets library.
Also, this might be useful: MinGW linker error: winsock
你错过了 wsock32 库。将其添加到您的依赖项中,它应该可以工作。
You miss wsock32 library. Add this to your dependencies and it should work.
