Building Adaptive Communication Environment (ACE) using MinGW

Question

I am building Adaptive Communication Environment (ACE) 6.4.2 using MinGW following steps in http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/ACE-INSTALL.html#mingw . I use Windows10 64 bit Operating system. I am very new to building C++ projects.

I installed MinGW from https://sourceforge.net/projects/mingw/files/ . I believe it is a 32 bit version. I used MinGW installation Manager to download all packages.

I downloaded ACE 6.4.2 from http://download.dre.vanderbilt.edu/ and extracted to E:/dependencies/ACE-6.4.2

The root level folder structure of MinGW is shown below.

I include E:/dependencies/MinGW/bin and E:/dependencies/MinGW/msys/1.0/bin to system variable path .

I did the following steps:

1. Open a MSYS shell . Set PATH environment variable to MinGW's bin directory:

   export PATH=/e/dependencies/MinGW/bin:$PATH

2. Added ACE_ROOT environment variable pointing to the root of ACE wrappers source tree:

   export ACE_ROOT=/e/dependencies/ACE-6.4.2/ACE_wrappers

3. Created a file called config.h in the $ACE_ROOT/ace directory that contains: #include "ace/config-win32.h"

4. Created a file called platform_macros.GNU in the $ACE_ROOT/include/makeinclude directory containing:

   include $(ACE_ROOT)/include/makeinclude/platform_mingw32.GNU INSTALL_PREFIX=/e/dependencies/ACE-6.4.2-install

5. In the MSYS shell,

   cd $ACE_ROOT/ace make

What I have been understood is that g++ within MinGW will be used.

And the error log

Ultimately, I have to use QT Creator for application development using ACE. And I could find only MinGw 32 bit versions of QT build. That is why I choose MinGW 32 bit for building ACE.

Answer 1

I encountered the same problem with timespec redefinition. I'm using tdm-gcc-5.1.0-3 with git-bash . In my case, the problem is that timespec is defined in both pthread.h and ace/os_include/os_time.h . One way to solve it is to edit 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"

An approach to use HAVE_STRUCT_TIMESPEC didn't work in my case. In general, it is not a good solution .

If you are using mingw + msys both installed from mingw-get , then you'll get timespec defined in time.h . Solution is similar:

// 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"

If it doesn't help, take a look at ace/os_include/os_time.h . You may find particular macro suitable for your problem.

As a side note, I'm getting link error when using tdm and git-bash . It looks quite strange, I don't yet know why it's happening. For example,

for 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

for ACE-6.4.0 :

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

for ACE-6.4.6 :

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

While mingw and msys provide successful build.

Answer 2

I have done exactly the same thing and encountered the same error. I understand it is an open source. However, the instruction needs to be updated or at least specifies the versions that are used to make the build. Adding "#define ACE_HAS_POSIX_TIME 1" in the config.h file does fix the error. The struct timespec is defined in mingw/include/time.h. (my g++.exe is at version 6.3.0). If ACE_HAS_POSIX_TIME is not defined, then $ACE_ROOT/ace/os_include/os_time.h will try to define it again, hence the error comes.

Answer 3

You can follow the error message, in your example:

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

If you open the file at that line, the typedef will be surrounded by an #if defined XXX macro, from which you can see that you need to define or undef XXX. For my, kind of similar issues for example I had to modify my config.h the following way:

#define ACE_HAS_POSIX_TIME 1
#define ACE_LACKS_TIMESPEC_T 1

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