Question

我正在http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/ACE-INSTALL.html#mingw中使用MinGW以下步骤构建自适应通信环境（ACE）6.4.2。我使用Windows10 64位操作系统。我是构建C ++项目的新手。

我从https://sourceforge.net/projects/mingw/files/安装了MinGW。我相信它是32位版本。我使用MinGW安装管理器下载所有软件包。

我从http://download.dre.vanderbilt.edu/下载了ACE 6.4.2并解压缩到E：/dependencies/ACE-6.4.2

MinGW的根级文件夹结构如下所示。

我将E：/ dependencies / MinGW / bin和E：/dependencies/MinGW/msys/1.0/bin包含在系统变量path中。

我做了以下步骤：

打开MSYS shell。将PATH环境变量设置为MinGW的bin目录：

export PATH=/e/dependencies/MinGW/bin:$PATH
添加了指向ACE包装器源树根的ACE_ROOT环境变量：

export ACE_ROOT=/e/dependencies/ACE-6.4.2/ACE_wrappers
在config.h目录中创建了一个名为$ACE_ROOT/ace的文件，其中包含： #include "ace/config-win32.h"
在platform_macros.GNU目录中创建了一个名为$ACE_ROOT/include/makeinclude的文件，其中包含：

include $(ACE_ROOT)/include/makeinclude/platform_mingw32.GNU INSTALL_PREFIX=/e/dependencies/ACE-6.4.2-install
在MSYS shell中，

cd $ACE_ROOT/ace make

我所理解的是g++中的MinGW将被使用。

最终，我必须使用QT Creator使用ACE进行应用程序开发。我只能找到MinGw 32位版本的QT版本。这就是为什么我选择MinGW 32位来构建ACE。

Answer 1

我遇到了与timespec重新定义相同的问题。我正在tdm-gcc-5.1.0-3使用git-bash。就我而言，问题是timespec和pthread.h都定义了ace/os_include/os_time.h。解决此问题的一种方法是编辑ace/config.h：

// Get 'timespec' explicitly from here. 
#include <pthread.h>

// Tell ACE to do not declare 'timespec'. 
#define ACE_HAS_POSIX_TIME 1

// Tell ACE to declare 'timespec_t' alias.
#define ACE_LACKS_TIMESPEC_T 1

// Default windows config, see ACE install manual.
#include "ace/config-win32.h"

使用HAVE_STRUCT_TIMESPEC的方法在我的案例中不起作用。一般来说，it is not a good solution。

如果您使用的mingw + msys都来自mingw-get，那么您将在timespec中定义time.h。解决方案类似：

// Tell ACE to do not declare 'timespec'. 
#define ACE_HAS_POSIX_TIME 1

// Tell ACE to declare 'timespec_t' alias.
#define ACE_LACKS_TIMESPEC_T 1

// Default windows config, see ACE install manual.
#include "ace/config-win32.h"

如果没有帮助，请查看ace/os_include/os_time.h。您可能会发现适合您的问题的特定宏。

作为旁注，我在使用tdm和git-bash时遇到链接错误。看起来很奇怪，我还不知道为什么会这样。例如，

代表ACE-6.3.2：

C:/TDM-GCC-32/bin/../lib/gcc/mingw32/5.1.0/../../../../mingw32/bin/ld.exe: cannot find .: Permission denied
collect2.exe: error: ld returned 1 exit status

代表ACE-6.4.0：

g++.exe: error: .shobj/Filecac: No such file or directory

代表ACE-6.4.6：

g++.exe: error: .shobj/Co: No such file or directory

虽然mingw和msys提供了成功的构建。

Answer 2

我做了完全相同的事情并遇到了同样的错误。我知道它是一个开源的。但是，该指令需要更新或至少指定用于进行构建的版本。添加 config.h文件中的“#define ACE_HAS_POSIX_TIME 1”确实修复了错误。 struct timespec在mingw / include / time.h中定义。（我的g ++。exe版本是6.3.0）。如果未定义ACE_HAS_POSIX_TIME，则$ ACE_ROOT / ace / os_include / os_time.h将尝试再次定义它，因此出现错误。

Answer 3

在示例中，您可以按照错误消息进行操作：

ace/os_include/os_time.h:56:16: error: redefinition of 'struct timespec'
 typedef struct timespec

如果在该行打开文件，则typedef将被 #if定义的XXX 宏包围，您可以从中看到需要定义或取消定义XXX的宏。对于我来说，例如类似的问题，我必须通过以下方式修改config.h：

#define ACE_HAS_POSIX_TIME 1
#define ACE_LACKS_TIMESPEC_T 1

#include "ace/config-win32.h"
#undef ACE_LACKS_CLOCKID_T
