IBM XLC++ 9.0/AIX 5.3] tr1/cstdint limit macros incompatible with system provided C headers
-------------------------------------------------------------------------------------------
Key: STDCXX-677
URL: https://issues.apache.org/jira/browse/STDCXX-677
Project: C++ Standard Library
Issue Type: Bug
Components: TR1.8 - C Compatibility
Affects Versions: 4.2.0
Reporter: Travis Vitek
Assignee: Travis Vitek
Fix For: 4.2.1
The following testcase fails to compile because both the C library stdint.h and our tr1/cstdint headers define defines the C99 limit macros. It looks like we need to avoid defining the macros if a previous definition already exists. Is that a sufficient solution? What if our defintion is different for some reason?

[jira] Commented: (STDCXX-677) [IBM XLC++ 9.0/AIX 5.3] tr1/cstdint
limit macros incompatible with system provided C headers
Posted by "Martin Sebor (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/STDCXX-677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12549248 ]
Martin Sebor commented on STDCXX-677:
-------------------------------------
I agree that we should avoid interfering with the native C library if it defines these things.
The tr1/ subdirectory isn't supported (whatever that means in our world) and its contents will eventually (in 4.3 or later) be moved directly under include, when we enable at least partial support for C++ 0x. Until then, I suppose we can guard against the re-#definition of these macros in our <cstdint>.

[jira] Updated: (STDCXX-677) [IBM XLC++ 9.0/AIX 5.3] tr1/cstdint
limit macros incompatible with system provided C headers
Posted by "Travis Vitek (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/STDCXX-677?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Travis Vitek updated STDCXX-677:
--------------------------------
Summary: [IBM XLC++ 9.0/AIX 5.3] tr1/cstdint limit macros incompatible with system provided C headers (was: IBM XLC++ 9.0/AIX 5.3] tr1/cstdint limit macros incompatible with system provided C headers)
> [IBM XLC++ 9.0/AIX 5.3] tr1/cstdint limit macros incompatible with system provided C headers
> --------------------------------------------------------------------------------------------
>
> Key: STDCXX-677
> URL: https://issues.apache.org/jira/browse/STDCXX-677
> Project: C++ Standard Library
> Issue Type: Bug
> Components: TR1.8 - C Compatibility
> Affects Versions: 4.2.0
> Reporter: Travis Vitek
> Assignee: Travis Vitek
> Fix For: 4.2.1
>
>
> The following testcase fails to compile because both the C library stdint.h and our tr1/cstdint headers define defines the C99 limit macros. It looks like we need to avoid defining the macros if a previous definition already exists. Is that a sufficient solution? What if our defintion is different for some reason?
