X-Received-From: 192.134.164.83 Subject: [Qemu-devel] [PATCH] Fix cursesw detection X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Samuel Thibault , pbonzini@redhat.com, mjt@tls.msk.ru, kraxel@redhat.com, peter.maydell@linaro.org Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP On systems which do not provide ncursesw.pc and whose /usr/include/curses.h does not include wide support, we should not only try with no -I, i.e. /usr/include, but also with -I/usr/include/ncursesw. To properly detect for wide support with and without -Werror, we need to check for the presence of e.g. the WACS_DEGREE macro. We also want to stop at the first curses_inc_list configuration which works, and make sure to set IFS to : at each new loop.
