Bug #: 56306
Summary: -m32 does not support all includes
Classification: Unclassified
Product: gcc
Version: 4.3.4
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: preprocessor
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: uwe.seidler@siemens-enterprise.com
Created attachment 29437
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29437
simple test program
Scenario: Compilation of a 32bit application on a 64bit host.
For "compiler internal" header files the preprocessor accesses the corret
header files, e.g. #include <bits/stdc++.h> includes 32/bits/stdc++.h.
For includes located somewher in the sysroot folders this usefull mechanism
does not work.
gcc-4.3 -m32 curlbr.c
does not work if 32bit variant of curlbuild.h is provided in a 32/curl folder.

In this case this is a bug of whoever provides curlbuild.h. I don't see how this is a bug in GCC, so I'm re-labeling it as enhancement. ^ permalink raw reply [flat|nested] 5+ messages in thread

It can't possibly know about arbitrary non-GCC paths or whether it's correct or safe to append "32" to those paths. ^ permalink raw reply [flat|nested] 5+ messages in thread
