From b7004b11991d154dbf6ff88e619b68b817b78bca Mon Sep 17 00:00:00 2001 From: gbeauche <> Date: Sun, 3 Jul 2005 13:05:36 +0000 Subject: [PATCH] Add necessary configury + support code to support slirp in SheepShaver, the user-space network emulation layer. Enable it on all Unix supported platforms where I know it works. --- SheepShaver/Makefile | 6 +- SheepShaver/src/Unix/Linux/ether_linux.cpp | 510 --------------------- SheepShaver/src/Unix/Makefile.in | 10 +- SheepShaver/src/Unix/configure.ac | 51 ++- SheepShaver/src/Unix/user_strings_unix.cpp | 1 + SheepShaver/src/Unix/user_strings_unix.h | 1 + 6 files changed, 57 insertions(+), 522 deletions(-) delete mode 100644 SheepShaver/src/Unix/Linux/ether_linux.cpp diff --git a/SheepShaver/Makefile b/SheepShaver/Makefile index 2895314a..8d08bc54 100644 --- a/SheepShaver/Makefile +++ b/SheepShaver/Makefile @@ -60,11 +60,11 @@ links: Unix/sigsegv.h Unix/sigsegv.cpp Unix/vm_alloc.h Unix/vm_alloc.cpp \ Unix/posix_sem.cpp Unix/video_vosf.h Unix/video_blit.h \ Unix/video_blit.cpp Unix/config.sub Unix/config.guess \ - Unix/keycodes Unix/tunconfig Unix/clip_unix.cpp \ - Unix/m4 Unix/Linux/scsi_linux.cpp Unix/Linux/NetDriver \ + Unix/keycodes Unix/tunconfig Unix/clip_unix.cpp Unix/m4 \ + Unix/Linux/scsi_linux.cpp Unix/Linux/NetDriver Unix/ether_unix.cpp \ Unix/Darwin/lowmem.c Unix/Darwin/pagezero.c Unix/Darwin/testlmem.sh \ dummy/audio_dummy.cpp dummy/clip_dummy.cpp dummy/serial_dummy.cpp \ - dummy/prefs_editor_dummy.cpp dummy/scsi_dummy.cpp SDL \ + dummy/prefs_editor_dummy.cpp dummy/scsi_dummy.cpp SDL slirp \ MacOSX/sys_darwin.cpp MacOSX/clip_macosx.cpp \ MacOSX/macos_util_macosx.h MacOSX/extfs_macosx.h \ MacOSX/extfs_macosx.mm Windows/clip_windows.cpp \ diff --git a/SheepShaver/src/Unix/Linux/ether_linux.cpp b/SheepShaver/src/Unix/Linux/ether_linux.cpp deleted file mode 100644 index 85c5c19d..00000000 --- a/SheepShaver/src/Unix/Linux/ether_linux.cpp +++ /dev/null @@ -1,510 +0,0 @@ -/* - * ether_linux.cpp - SheepShaver Ethernet Device Driver (DLPI), Linux specific stuff - * - * SheepShaver (C) 1997-2005 Marc Hellwig and Christian Bauer - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
