* config: compile test rather than run testChunwei Chen2014-03-201-1/+1
| | | | | | | | | | When testing compiler flags, we only need to do compile test. Otherwise, configure will fail with "configure: error: cannot run test program while cross compiling" when cross compiling. Signed-off-by: Chunwei Chen <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #2191
* In autoconf v2.68, AC_LANG_PROGRAM must be quotedPrakash Surya2011-11-281-1/+1
| | | | | | | | | | | | | | | | | This change updates the AC_LANG_PROGRAM autoconf macro invocations to be wrapped in quotes. As of autoconf version 2.68, the quotes are necessary to prevent warnings from appearing. Specifically, the autoconf v2.68 Forward Porting Notes specifies: It is important to note that you need to ensure that the call to AC_LANG_SOURCE is quoted and not expanded, otherwise that will cause the warning to appear nonetheless. Finally, because of the additional quoting we can drop the extra quotas used by the ZFS_AC_CONFIG_USER_STACK_GUARD autoconf check. Signed-off-by: Brian Behlendorf <[email protected]> Closes #464

The previous commit 8a7e1ceefa430988c8f888ca708ab307333b4464 wasn't quite right. This check applies to both the user and kernel space build and as such we must make sure it runs regardless of what the --with-config option is set too. For example, if --with-config=kernel then the autoconf test does not run and we generate build warnings when compiling the kernel packages.
