首先把XFree86的包解开,看里面的BUILD.txt文档。跟着里面作就可以了,主要是生成lndir命令(很有用的命令)创建工作目录连接。然后创建

config/cf/host.def
代码
#define TinyXServer     YES
#define XfbdevServer    YES
#define BuildServersOnly YES
#define XF86Server      NO
#define XdmxServer      NO
#define XnestServer     NO
#define XsunServer      NO
#define Xsun24Server    NO
#define XsunMonoServer  NO
#define XsunLynxServer  NO
#define XSavageServer   NO
#define XIgsServer      NO
#define XTridentServer  NO
#define XchipsServer    NO
#define Xmach64Server   NO
#define Xi810Server     NO
#define XSis530Server   NO
#define XTrioServer     NO
#define XipaqServer     NO
#define XTS300Server    NO
#define XItsyServer     NO
#define XvesaServer     NO
#define XDarwinServer   NO
#define XVirtualFramebufferServer   NO
#define XprtServer      NO
#define BuildXprintClients  NO
#define CrossCompiling      YES
#define ProjectRoot             /usr/X11R6
#define NothingOutsideProjectRoot   YES

#define BuildLibraries         YES
#define BuildDocs       NO

#undef  BuildRender
#define BuildRender             YES

#define UseRgbTxt               YES

#define OmitSnfSupport          YES
#define HasMTRRSupport          NO
#define UseX86Emu               NO
#define BuildGlxExt     NO

#define XF86INT10_BUILD         X86INT10_STUB

#define XInputDrivers       mouse keyboard


如果是交叉编译,还需要修改(如果采用本机编译器,则不要进行此步骤)

config/cf/cross.def
代码
/* $XFree86: xc/config/cf/cross.def,v 1.3 2002/04/04 14:05:33 eich Exp $ */
/*
* This file contains redefinitions of some symbols to enable
* cross compilation: e.g. paths for include files and paths to
* compiler images.  It will have to be edited to reflect these
* given your local configuration.
*/
#undef i386Architecture
#undef Arm32Architecture
#define Arm32Architecture

#undef OptimizedCDebugFlags
#define OptimizedCDebugFlags    -O2
#define ServerCDebugFlags   -O2
#undef StandardDefines
#define StandardDefines     -Dlinux -D__arm__ -D_POSIX_SOURCE \
                -D_BSD_SOURCE -D_GNU_SOURCE -DX_LOCALE -DUSE_DYNAMIC_LC -DUSE_UTF8_LOADER \
                -DUSE_DYNAMIC_LOADER

#undef CcCmd
#define StdIncDir
#define PreIncDir
#undef PostIncDir
#define PostIncDir
#define CcCmd /opt/cross-compile-arm/gcc-3.3/bin/arm-linux-gcc -L/opt/cross-compile-arm/gcc-3.3/arm-linux/lib/ -I/opt/cross-compile-arm/gcc-3.3/arm-linux/include/

#undef CplusplusCmd
#define HasCplusplus NO
#define CplusplusCmd NO
#define DoRanlibCmd YES
#define RanlibCmd /opt/cross-compile-arm/gcc-3.3/bin/arm-linux-ranlib
#undef ExtraLoadFlags
#define ExtraLoadFlags
#define FbNoPixelAddrCode
#undef TermcapLibrary
#define TermcapLibrary -L/usr/lib/ -lncurses

#undef LdPostLib
#define LdPostLib

#undef ExtensionOSDefines
#define ExtensionOSDefines

#define ServerXdmcpDefines  /**/

/*
#define HostCcCmd /opt/cross-compile-arm/gcc-3.3/bin/arm-linux-gcc -L/opt/cross-compile-arm/gcc-3.3/arm-linux/lib/ -I/opt/cross-compile-arm/gcc-3.3/arm-linux/include/
*/

#define HostCcCmd gcc
#include <cross.rules>


然后修改lib/X11/Imakefile,在第一层的#if中增加
代码
&& !TinyXServer

条件,这样编译tinyx的时候也会编译X11中的库,不加这个条件会出错。

本机编译运行命令
代码
make World > World.log 2>&1

交叉编译运行命令(假设交叉编译器的gcc程序在 /opt/cross-compile-arm/gcc-3.3/bin/ 目录下)
代码
make World CROSSCOMPILEDIR=/opt/cross-compile-arm/gcc-3.3/bin/ > World.log 2>&1


编译好了以后,拷贝到板子上(本机编译可以运行 make install),运行:Xfbdev -fp /usr/share/fonts -fn -misc-fixed-medium-r-normal--18-120-100-100-c-90-iso8859-1 -fc -misc-fixed-medium-r-normal--18-120-100-100-c-90-iso8859-1。如果一切正常,X11会起来的。其中字体部分可以通过fontconfig配置好,然后直接运行Xfbdev就可以了。

另外,编译tinyx在linux kernel2.4运行时出错。NR_KEY在2.4的内核中是128,在2.6的内核中是256,因此数组越界。在tinyx中把NR_KEYS设置为128就可以了。

还有如果在tinyx中新加一个硬件显卡的framebuffer驱动也比较麻烦。主要步骤如下:修改xfree86.cf文件;修改Xserver目录下的Imakefile文件;修改tinyx目录下的Imakefile文件;增加tinyx相应的驱动(在tinyx目录下增加驱动的目录和相应的文件)。
