记录Mesa配置文件如下：
Mesa版本：Mesa-10.2.3
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/Mesa --target=arm-linux --host=arm-linux --enable-gles2 --enable-gles1 --disable-glx --enable-egl --disable-dri --enable-shared-glapi --with-egl-platforms=fbdev --with-dri-drivers=swrast
- 或者
- unset PKG_CONFIG_PATH
- export PKG_CONFIG_PATH=/home/work/DownLoad/presen/lib/pkgconfig:/home/work/DownLoad/libdrm/lib/pkgconfig
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --target=arm-linux --host=arm-linux --prefix=/home/work/DownLoad/Mesa-10.0 --enable-gl --enable-gles2 --enable-gles1 --enable-opengl --enable-shared-glapi --disable-dri --enable-shared-dricore --enable-gles1 --enable-opengl --enable-gallium-egl --with-egl-platforms=fbdev --with-gallium-drivers=swrast --with-dri-drivers=swrast CFLAGS="-I/home/work/DownLoad/libudev/include -L/home/work/DownLoad/libudev/lib/arm-linux-gnueabi"
- make &&make install
Qt配置:
- ./configure -prefix /usr/local/qt-5.2.1-embedded-arm-quick -release -opensource -qt-libpng -qt-libjpeg -plugin-sql-sqlite -widgets -qt-sql-sqlite -make libs -no-cups -no-nis -no-iconv -no-dbus -no-openssl -no-iconv -no-accessibility -no-javascript-jit -no-sse2 -silent -xplatform linux-arm-gnueabi-g++ -nomake tools -nomake examples -nomake tests -qt-freetype -opengl es2 -qreal float -no-glib -strip -xinput2 -linuxfb -plugindir /usr/local/qt-5.2.1-embedded-arm-quick/plugin -qmldir /usr/local/qt-5.2.1-embedded-arm-quick/qml -importdir /usr/local/qt-5.2.1-embedded-arm-quick/imports -L/home/work/DownLoad/Mesa/lib -I/home/work/DownLoad/Mesa/include -confirm-license "$@" -verbose
- make && make install
- qmake.conf中需要加入:QMAKE_LIBS_OPENGL_ES2 = -lglapi -lGLESv2 -lEGL
- 这是由于libGLESv2.so依赖于libglapi.so，可以用arm-none-linux-gnueabi-ld查看关系库的依赖关系。Mesa交叉编译的时候如果没有 --enable-shared-glapi,则会报如下错误：
- libGLESv2.so: undefined reference to ‘_glapi_get_dispatch‘
- libGLESv2.so: undefined reference to‘_glapi_Dispatch‘
XLib所有源码下载地址：
- http://cgit.freedesktop.org/xorg/
http://cgit.freedesktop.org/xorg/
ubuntu 命令行批量下载: wget -r -np -nd ftp://mirrors.go-part.com/xorg/X11R7.7/
记录LibX11-1.3.2的配置如下：
- echo enable_malloc0returnsnull=yes>arm-linux.cache
这一句是为了保证可以交叉编译，不然交叉编译的时候test是不会过的，会报如下错误:
checking whether malloc(0) returns NULL... configure: error: in `/home/work/DownLoad/libX11-1.3.2‘:
configure: error: cannot run test program while cross compiling
这是由于xlib在使用--host=arm-linux的时候禁止交叉编译。解决方法为从congfirue中找到报错的那一句，查看具有+set的那一句脚本，例如本例中为：
- vim configure
- 查找checking whether malloc(0) returns Null...这一句，得到以下信息
- # Check whether --enable-malloc0returnsnull was given.
- if test "${enable_malloc0returnsnull+set}" = set; then
- enableval=$enable_malloc0returnsnull; MALLOC_ZERO_RETURNS_NULL=$enableval
- else
- MALLOC_ZERO_RETURNS_NULL=auto
- fi
-
-
- { $as_echo "$as_me:$LINENO: checking whether malloc(0) returns NULL" >&5
- $as_echo_n "<span style="color:#FF0000;">checking whether malloc(0) returns NULL... " >&6; }
- if test "x$MALLOC_ZERO_RETURNS_NULL" = xauto; then
- if test "$cross_compiling" = yes; then
- { { $as_echo "$as_me:$LINENO: error: in \`$ac_pwd‘:" >&5
- $as_echo "$as_me: error: in \`$ac_pwd‘:" >&2;}
- { { $as_echo "$as_me:$LINENO: error: cannot run test program while cross compiling
- See \`config.log‘ for more details." >&5
- $as_echo "$as_me: error: cannot run test program while cross compiling
- See \`config.log‘ for more details." >&2;}
由于他是在if test "${enable_malloc0returnsnull+set}" = set;
- make clean && make distclean
- rm -rf arm-linux.cache
- echo enable_malloc0returnsnull=yes>arm-linux.cache
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/ --disable-xf86bigfont --host=arm-linux --target=arm-linux CFLAGS="-I/home/work/DownLoad/libX11/include -I/home/work/DownLoad/libX11/libxcb/include -L/home/work/DownLoad/libX11/lib -L/home/work/DownLoad/libX11/libxcb/lib" --includedir=/home/work/DownLoad/libX11/include XPROTO_LIBS=/home/work/DownLoad/libX11/lib --cache-file=arm-linux.cache
- make && make install
- CFLAGS="-I/home/work/DownLoad/libX11/include -L/home/work/DownLoad/libX11/lib",这句制定xPorto的路径，因为需要用到xProto中的x.h
交叉编译X11需要交叉编译Xproto(版本xproto-7.0.17):
Xporto下载地址：
- http://cgit.freedesktop.org/xorg/proto/xproto/
- configXproto.sh如下：
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/ --host=arm-linux --target=arm-linux
- make && make install
由于需要用到Xtrans.h，故而需要下载xtrans，下载地址为：
- http://www.x.org/releases/X11R7.5/src/lib/
我所选的版本为：xtrans-1.2.5
交叉编译和上面的类似
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/ --host=arm-linux --target=arm-linux --cache-file=arm-linux.cache
- make && make install
由于报错XKB.c:36:37: fatal error: X11/extensions/XKBproto.h: No such file or directory，故而还需要用到kbproto-1.0.6
kbproto-1.0.6下载地址：
- http://cgit.freedesktop.org/xorg/proto/kbproto/
kbproto-1.0.6交叉编译和上面的类似：
- make clean && make distclean
- rm -rf configure
- ./autogen.sh
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/kbproto --host=arm-linux --target=arm-linux
- make && make install
需要XI.h,需要下载inputproto-2.1.99.6，下载地址为：
- http://cgit.freedesktop.org/xorg/proto/inputproto/
iputProto-2.1.99.6交叉编译和上面类似
- make clean && make distclean
- rm -rf configure
- ./autogen.sh
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/inputporto/ --host=arm-linux --target=arm-linux
错误：../include/X11/Xlib-xcb.h:7:21: fatal error: xcb/xcb.h: No such file or directory
需要下载libXcb,下载地址
- http://xcb.freedesktop.org/dist/
libxcb-1.8.1交叉编译如下：
- export PKG_CONFIG_PATH=/home/work/DownLoad/libX11/xcbproto/lib/pkgconfig
- make clean && make distclean
- rm -rf arm-linux.cache
- echo ac_cv_path_XSLTPROC=/home/work/DownLoad/libX11/libxslt/bin > arm-linux.cache
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/libxcb/ CFLAGS="-I/home/work/DownLoad/libX11/libxslt/include -I/home/work/DownLoad/libX11/LibXau/include -I/home/work/DownLoad/libX11/include -L/home/work/DownLoad/libX11/libxslt/lib -L/home/work/DownLoad/libX11/LibXau/lib" --host=arm-linux --target=arm-linux --cache-file=arm-linux.cache
- 错误信息：configure: error: XCB requires xsltproc
下载xsltproc，下载地址：
- https://git.gnome.org/browse/libxslt/
- <pre name="code" class="html">CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --with-libxml-libs-prefix=/home/work/DownLoad/libX11/libxml2/lib --with-libxml-include-prefix=/home/work/DownLoad/libX11/include/libxml2/libxml/ --prefix=/home/work/DownLoad/libX11/libxslt/ --host=arm-linux --target=arm-linux
如果已经交叉编译并且已经指定libxml2的路径，然而还是找不到libxml2,可以将在congfigure中手动指出xml的路径
LIBXML_CONFIG_PREFIX="/home/work/DownLoad/libX11/libxml2"
xsltproc需要下载libxml，下载地址：
- ftp://xmlsoft.org/libxml2/
- 交叉编译和上面的类似
-
- xcb需要xcb-proto，下载地址:http://xcb.freedesktop.org/dist/
- xcb-proto-1.7交叉编译如下：
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/xcbproto/ --host=arm-linux --target=arm-linux
- make && make install
- xcb需要libxau,下载地址：http://cgit.freedesktop.org/xorg/lib/libXau/
- libXau-1.0.7交叉编译：
- make clean && make distclean
- rm -rf configure
- ./autogen.sh
- CC=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc CXX=/usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ ./configure --prefix=/home/work/DownLoad/libX11/LibXau/ --host=arm-linux --target=arm-linux CFLAGS="-I/home/work/DownLoad/libX11/include"
- make && make instal
附录一下交叉编译成功后的lib库的下载地址，用以以后下载使用：
