Define _SVID_SOURCE and _POSIX_SOURCE for Comeau

[mloskot <mateusz@…>]

According to ​manual of Comeau C++ 4.3, on Linux

In order to use some POSIX or SVID extension routines/struct's, it may be necessary to define _POSIX_SOURCE or _SVID_SOURCE

The attached patch adds these definitions to Jamfile.v2 for the build. However, I don't know where it would be required else, for example, when Boost.Test is used in included mode, etc.

My environment:

• Linux 32-bit
• Comeau C/C++ 4.3.10.1
• GCC 4.3.3

Patch adding <define> entries enabling POSIX support from Comeau

[mloskot <mateusz@…>]

Gennadiy,

GI found another workaround which is simpler and seems to solve number of other issues related to C99 and POSIX. It is define of _ GNU_SOURCE in Jamfile:

<toolset>como-linux:<define>_GNU_SOURCE=1

Quick test shows that it enables C99 features like even snprintf and vsnprintf as well as POSIX features like time functions or signals.

I've just discovered this define while trying to enable signal.h definitions, but I'm going to consult it with Comeau team, so in case you'd be up to, please do not apply these patches here neither the patch I added today ago for #3558 . I'm going to confirm all these and run more tests. Sorry for making noise in the tickets, but I think it may be relevant to have some steps documented. Thanks for patience!

Is it fixed already in common Jamfile?

I have submitted those fixes in separate ticket #3692 for Boost Build. I think this ticket can be closed.
