From: Paul Fertser Date: Wed, 3 Jul 2013 09:54:16 +0000 (+0400) Subject: ft2232_libftdi: perform basic configure checking when cross-compiling X-Git-Tag: v0.8.0-rc1~375 X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=6aba46257665b3438e6fef0859ee641bc5a6e71f;hp=bb60cc4fef07fdb2ba090a796430f6f15e9c40a4;ds=sidebyside ft2232_libftdi: perform basic configure checking when cross-compiling When cross-compiling, current configure script fully ignores libftdi unavailability and proceeds with LIBS having -lftdi -lusb, that results in a non-obvious failure much later. Try to verify libftdi is available by checking if ftdi_new function is linkable.
