交叉编译用mingw在Linux上运行一个pthread

我尝试用mingw编译一个简单的线程程序用于Win上的Linux。交叉编译用mingw在Linux上运行一个pthread

为此，我加载source并将源代码放到我的目录中。比我写了一个makefile。对于Linux，它运行得非常好。但赢我有许多错误 - 他们中的一些我已经不能修复：

我如何解决这个问题的链接？

到达亚尔RAI

的包括我的头是（按顺序，我认为，他们被称为）：

的main.c

/*#include <errno.h> */ 
/*#include <fcntl.h> */ 
#include <inttypes.h> 
#include "./pthreads/pthread.h" 
#include <stdio.h>  
#include <stdlib.h> 
#include <string.h> 
/*#include <termios.h> */ 
/*#include <unistd.h> */ 

#include "usleep.h"  /* um usleep nutzen zu können */

usleep.h

... 
#include "unistd.h" 
#include <inttypes.h> 
#include <stdio.h> 
...

可能是因为windows目标包含unistd.h是错误的吗？

我还额外减少标题的数量并在任何可能的情况下更改它们的顺序，但错误仍然存在。我不知道它来自....

的main.c

#include <inttypes.h> /* Spezielle int-Datentypen */ 
#include <stdio.h> 

#if defined(FORCEWIN) || defined(_WIN64) || defined(_WIN32) 
    #include <time.h> 
    #include <winsock2.h> 
#elif __unix /* all unices not caught above */ 
    #include <sys/time.h> 
    #include <sys/socket.h> 
#endif

我看在lib的objectfile太的发现符号主要有一点不同：

可能剥离或目标文件重命名符号它是有用的？

根据gcc规则'如果任何[静态]库A依赖于库B中定义的符号，则库A应该首先出现在提供给链接器的列表中。“请检查源文件的顺序是否有任何不匹配和你的build命令中的库。 –

为了让你的编译器错误可以被不懂德语的人阅读，运行'LC_ALL = C make'。 –

谢谢 - 我会添加这个 – Alex44

错误：

./usleep.o:usleep.c:(.text+0x3c): undefined reference to `__imp_select'

意味着符号__imp_select没有定义。它可能在其他一些C文件中，您没有包含在最终的链接步骤中。

是的，我理解它的方式，但没有什么'grep -e __imp_select *'什么都不给我。 – Alex44

http://stackoverflow.com/questions/6356123/where-to-find-select-source-code-in-glibc-source –

在我看来，这是正确的方向。但我无法修复它。我必须添加编译器标志，以便找到lib。在上面的链接中，它意味着包含“glibc” - 但没有任何事情发生.... – Alex44

它看起来像你已经创建了一个静态库文件libpthreadGC2.a，但你的链接命令x86_64-w64-mingw32-gcc ./main.o ./usleep.o ./pthreads/pthread.o -o possix.exe -v只链接三个目标文件，它不在其中。尝试将-lpthreadGC2或libpthreadGC2.a添加到链接命令。

如果要检查目标文件是否包含缺少的符号（例如__imp_pthread_mutex_unlock），则可以尝试运行nm libpthreadGC2.a | grep '__imp_pthread_mutex_unlock'以查看它是否存在。

我在自述文件中阅读了链接到的pthread源文件，您必须在构建时定义PTW32_STATIC_LIB - 是否存在删除-DPTW32_STATIC_LIB选项的原因？

2013-09-23 15:24:43

我无法确定目标文件的格式。 nm总是告诉'文件格式不被识别'。顺便一提。有可能通过其他选择制作pthread-lib。有_dll C清理code_，_inlined dll C清理code_和_inlined静态库C清理code_。我应该使用另一个？ – Alex44

在调试模式中，我看到所有的possix命令都是未定义的引用。在手动pf pthread中，它说我必须使用CFLAG -pthread - 但是如果我使用它，编译器不会找到lib：'x86_64-w64-mingw32-gcc：error：无法识别的选项'-pthread'' – Alex44

如果我使用'x86_64-w64-mingw32-nm main.o'而不是'nm'它可能会查看目标文件:) 我会将这些响应添加到问题中... – Alex44

交叉编译用mingw在Linux上运行一个pthread
