# Default build rules for all user space components, every Makefile.am
# should include these rules and override or extend them as needed.

Support custom build directories and move includes One of the neat tricks an autoconf style project is capable of is allow configurion/building in a directory other than the source directory. The major advantage to this is that you can build the project various different ways while making changes in a single source tree. For example, this project is designed to work on various different Linux distributions each of which work slightly differently. This means that changes need to verified on each of those supported distributions perferably before the change is committed to the public git repo. Using nfs and custom build directories makes this much easier. I now have a single source tree in nfs mounted on several different systems each running a supported distribution. When I make a change to the source base I suspect may break things I can concurrently build from the same source on all the systems each in their own subdirectory. wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz tar -xzf zfs-x.y.z.tar.gz cd zfs-x-y-z ------------------------- run concurrently ---------------------- <ubuntu system> <fedora system> <debian system> <rhel6 system> mkdir ubuntu mkdir fedora mkdir debian mkdir rhel6 cd ubuntu cd fedora cd debian cd rhel6 ../configure ../configure ../configure ../configure make make make make make check make check make check make check This change also moves many of the include headers from individual incude/sys directories under the modules directory in to a single top level include directory. This has the advantage of making the build rules cleaner and logically it makes a bit more sense.

AM_CFLAGS = -std=gnu99 -Wall -Wstrict-prototypes -fno-strict-aliasing
compile with -fno-omit-frame-pointer By default, depending on the version, gcc can reuse the frame pointer register. This is a micro-optimization that might help on some very old x86 processors. However, it also makes dynamic tracing less useful because the stacks cannot be easily observed. This rule change instructs gcc to use the -fno-omit-frame-pointer option when compiling.

AM_CPPFLAGS += -DHAVE_LARGE_STACKS=1
Use large stacks when available While stack size will vary by architecture it has historically defaulted to 8K on x86_64 systems. However, as of Linux 3.15 the default thread stack size was increased to 16K. These kernels are now the default in most non- enterprise distributions which means we no longer need to assume 8K stacks. This patch takes advantage of that fact by appropriately reverting stack conservation changes which were made to ensure stability. Changes which may have had a negative impact on performance for certain workloads. This also has the side effect of bringing the code slightly more in line with upstream.

AM_CPPFLAGS += -DTEXT_DOMAIN=\"zfs-linux-user\"
Add defs for makefile installation dir vars Add macro definitions to AM_CPPFLAGS to propagate makefile installation directory variables for libexecdir, runstatedir, sbindir, and sysconfdir. https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Installation-Directory-Variables.html A corollary is that you should not use these variables except in makefiles. For instance, instead of trying to evaluate datadir in configure and hard-coding it in makefiles using e.g., 'AC_DEFINE_UNQUOTED([DATADIR], ["$datadir"], [Data directory.])', you should add -DDATADIR='$(datadir)' to your makefile's definition of CPPFLAGS (AM_CPPFLAGS if you are also using Automake). The runstatedir directory is for "installing data files which the programs modify while they run, that pertain to one specific machine, and which need not persist longer than the execution of the program". https://www.gnu.org/prep/standards/html_node/Directory-Variables.html It will be defined by autoconf 2.70 or later, and default to "$(localstatedir)/run". http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commit;h=a197431414088a417b407b9b20583b2e8f7363bd Signed-off-by: Chris Dunlap <cdunlap@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #2
