[jira] [Commented] (QPID-3295) Under some conditions autoconf incorrectly detects that gcc doesn't support -Werror

Andrew Stitcher commented on QPID-3295:
---
Configure.ac uses the gl_COMPILER_FLAGS macro to test whether the compiler
accepts a particular flag. However the program it uses to test compile has an
unused variable in it.
The program is:
int main() {
int x;
;
return 0;
}
when compiled with -Wall -Werror this program reports an error and so autoconf
thinks that -Werror isn't a valid flags for gcc
Under some conditions autoconf incorrectly detects that gcc doesn't support
-Werror

Key: QPID-3295
URL: https://issues.apache.org/jira/browse/QPID-3295
Project: Qpid
Issue Type: Bug
Affects Versions: 0.8, 0.10
Reporter: Andrew Stitcher
Assignee: Andrew Stitcher
Labels: autoconf, gcc
If CFLAGS or CXXFLAGS contains -Wall when running configure, autoconf
incorrectly detects that gcc doesn't support -Werror
This is problematic because it is an important aspect of our policy that
there should be no compiler warnings, and this bug stops this being enforced.
Notably, the fedora package build has this issue and has been shipping with
some unnoticed warnings for a while.
