 Posted: Fri Mar 30, 2012 7:07 pm Post subject: Errors compiling with MinGW |
 |
|
I'm attempting to rebuild my project under Windows using MinGW (using GCC 4.6.2)., but I'm getting an error immediately at the line where I include cml.h (before I even use it).
It looks like the main issue is in regard to the use of "ssize_t". I'm not sure if this problem is specific to MinGW or GCC, or if MSVC was just more tolerant of something CML is doing?
I tried both the 1.0.3 release, and the latest in SVN, and both give the same result.

| I don't currently have that particular toolchain available (maybe Demian will have an answer), but in the meantime, could you post a minimal program that generates the error? (Ideally something with no dependencies so that one of us can drop it into our compiler if needed.) |

The error is triggered by including the header, so this does the same thing:
| Code: | #include <cml/cml.h>
int main( void )
{
return 0;
}
|
However, in the process of testing this, I've narrowed the problem down, and it may just be a GCC issue. The above file compiles fine, as long as you don't enable GCC's C++0x support (via "-std=c++0x"). Once you add that flag, it spews the errors I listed previously.
On the other hand, I just found that using the "-std=gnu++0x" flag (which allows for GCC-specific extensions on top of C++0x) allows it to compile again. Again, I don't know if this is a GCC issue, or if CML is doing something that isn't conforming to the new standard without the use of an extension. But at least it's compiling now.  |

I uploaded a quick fix to the SVN repository, but I could only test it on gcc 4.6.2 (no -std, -std=c++0x, -std=gnu++0x) and VC10 Express at this point. The changes also fix some compilation errors in the performance tests, but shouldn't affect general use.
Cheers,
Demian |

| That appears to have done the trick! The test compiles successfully now, both with -std=c++0x and -std=gnu++0x. Thanks! |
