From 2b18a37786a45cd97a9b0481b49949210d22fc4a Mon Sep 17 00:00:00 2001 From: maximilian attems Date: Fri, 15 Jul 2011 11:18:13 +0800 Subject: [SHELL] Fix klibc DEBUG compilation dash didn't compile in DEBUG mode against klibc for all long time. Now it only fails at link stage for not having setlinebuf(3) and freopen(3). Fixes: usr/dash/show.o: In function `opentrace': show.c:(.text+0x36): undefined reference to `freopen' show.c:(.text+0x86): undefined reference to `setlinebuf' Skip setlinebuf and use fclose/fopen inside __KLIBC__ Compile tested with debug in klibc and against glibc in dash repo.
