* Make license compatibility checks consistentBrian Behlendorf2014-10-171-1/+1
| | | | | | | | Apply the license specified in the META file to ensure the compatibility checks are all performed consistently. Signed-off-by: Brian Behlendorf <[email protected]> Issue #2757
* Only use gcc -Wunused-but-set-variable when availableBrian Behlendorf2013-01-101-1/+1
| | | | | | | | | | | | | | | | | | | Certain versions of gcc generate an 'unrecognized command line option' error message when -Wunused-but-set-variable is used unconditionally. This in turn can cause several of the autoconf tests to misdetect an interface. Now, the use of -Wunused-but-set-variable in the autoconf tests was introduced by commit b9c59ec8 to address a gcc 4.6 compatibility problem. So we really only need to pass this option for version of gcc which are known to support it. Therefore, the tests have been updated to use the result of the existing ZFS_AC_CONFIG_ALWAYS_NO_UNUSED_BUT_SET_VARIABLE which determines if gcc supports this option.

* Fix configure tests to play nice with GCC 4.6Prakash Surya2011-11-291-0/+3
| | | | | | | | | | | | As of GCC 4.6, specific kernel 2.6.32 header files do not compile cleanly without warnings. One specific example of this is the arch/x86/include/asm/percpu.h file. Thus, a few of the configure tests were getting hung up on this and the '-Wno-unsued-but-set-variables' compile option had to be introduced.

* Add build systemBrian Behlendorf2010-08-311-0/+37
Add autoconf style build infrastructure to the ZFS tree. This includes autogen.sh, configure.ac, m4 macros, some scripts/*, and makefiles for all the core ZFS components.
