From: Bartosz Golaszewski Date: Thu, 9 Feb 2023 20:03:56 +0000 (+0100) Subject: configure: verify the availability of twalk_r() for tests X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ceaf80e5aba71a01b2df0d708e11ffbf74875842;p=qemu-gpiodev%2Flibgpiod.git configure: verify the availability of twalk_r() for tests Some C libraries (notably musl) don't have twalk_r() as of yet. Add a check for it in configure so that we fail sooner rather than at build-time.
