Subject: configure.ac: Add AC_CANONICAL_SYSTEM macro.
X-Git-Tag: libsigrok-0.4.0~650
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=3cdff6cd2d1ce64e901540fa86a263666222ac07;p=libsigrok.git

configure.ac: Add AC_CANONICAL_SYSTEM macro.

In order to determine the target OS when cross-compiling libsigrok
we need autotools to set the 'target_os' variable. This macro
determines the system type and sets output variables to the names
of the canonical system types.
