'configure' uses this to find programs.

In some cases it may be necessary to work around configuration results that do
|
||||
not match reality. For example, OS X 10.12 in conjunction with XCode 8 adds
|
||||
the os_unfair_lock_*() API, but if XCode 8 is used to build jemalloc on older
|
||||
versions of OS X, the configure script will determine that os_unfair_lock_*()
|
||||
is compilable, yet run-time failures will result. To work around this
|
||||
(ignoring that MACOSX_DEPLOYMENT_TARGET may be the correct fix), create a cache
|
||||
file (called e.g. darwin.cache) with the following contents to override the
|
||||
relevant configuration variable defined in configure.ac:
|
||||
|
||||
je_cv_os_unfair_lock=no
|
||||
|
||||
Invoke configure as such:
|
||||
|
||||
./configure --cache=darwin.cache

=== Advanced compilation =======================================================

To build only parts of jemalloc, use the following targets:
