miniGui交叉编译

本文主要描述minigui交叉编译过程：

1.jpeg-7

step1:
./configure --prefix=/home/book/work/toolchain_book/arm/jpeg-7 --host=arm-linux CC=arm-linux-gnueabihf-gcc

step2:
make

step3:
make install

2.freetype

step1:
./configure --prefix=/home/book/work/toolchain_book/arm/freetype --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc –with-zlib=no
step2:
make
step3:
make install

3.harfbuzz

step1:

./configure --prefix=/home/book/work/toolchain_book/arm/harfbuzz --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --with-glib=no --with-freetype=yes PKG_CONFIG_PATH=/home/book/work/toolchain_book/arm/freetype/lib/pkgconfig

step2:
make
step3:
make install

FAQ:
1.添加了—with-freetype=yes，执行configure后报错：
configure: error: FreeType support requested but libfreetype2 not found
解决办法：
添加变量PKG_CONFIG_PATH

4.zlib

step1:
./configure --shared –prefix=/home/book/work/toolchain_book/arm/zlib
step2:
修改Makefile文件 ,在工具链前加上arm-linux-gnueabihf-
step3:
make
step4:
make install

FAQ:
./configure –help
usage:
configure [–shared] [–prefix=PREFIX] [–exec_prefix=EXPREFIX]
[–libdir=LIBDIR] [–includedir=INCLUDEDIR]

Zlib配置是不支持—host项，交叉编译时需要手动更改Makefile，将Makfile里的gcc、ar、ranlib均加上前缀arm-linux-gnueabihf-，再执行make && make install，编译安装成功后在—prefix指定的目录下生成include、shared和lib目录.

5.libpng

step1:
./configure --prefix=/home/book/work/toolchain_book/arm/libpng --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc执行此操作直接报错：configure: error: zlib not installed.继续添加其他变量依然无法解决该问题。

解决办法：
要解决这个问题最重要的是要了解到libpng库是不需要configure的，因为在scripts目录下已经提供makefile，所以没有必要使用configure来创建makefle文件了。
因此把scripts目录下makefile.linux拷贝到源码包根目录中，直接make就可以。但是为了解决找不到zlib库这个问题，所以需要修改这个makefile。

以下是安装libpng的具体步骤：
（1）cp scripts/makefile.linux makefile

（2）vim makefile

（3）makefile中找到zlib相关的两行，修改成实际的zlib/lib和zlib/include，再找到prefix项，修改为你想prefix的目录中，

如果此处是交叉编译的话，还需要在cc那边把gcc修改成您系统的交叉编译器，比如：arm-linux-gcc

（4）保存并且make && make install

6.chipmunk

step1:
cmake -DCMAKE_C_COMPILER=arm-linux-gnueabihf-gcc -DCMAKE_INSTALL_PREFIX=/home/book/work/toolchain_book/arm/chipmunk
step2:
make
step3:
make install

如果cmake命令不执行，先下载cmake和cmake-gui，cmake-gui是图形命令

7.libminigui

FAQ:
1.pcxvfb.c: In function ‘PCXVFB_VideoInit’:

Makefile:386: recipe for target ‘pcxvfb.lo’ failed
make[4]: *** [pcxvfb.lo] Error 1
主要原因是在链接的时候出现了/usr/include路径，

configure: WARNING: unrecognized options: --enable-rtosxvfb, --enable-pcxvfb

查看configure -h，可以找到相对应的功能模块，这些模块是我们移植过程中不需要的，禁用此模块便可以编译通过。（–enable-videortosxvfb –enable-videopcxvfb）

step1:
./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --prefix=/home/book/work/toolchain_book/arm/minigui --with-ft2-includes=/home/book/work/toolchain_book/arm/freetype/include/freetype2 --with-runmode=ths --enable-videoqvfb=no --enable-videortosxvfb=no --enable-videopcxvfb=no --enable-videodri=no

此时出现—with-ft2-includes赋值无效，在configure文件中找到对应的位置发现对该变量赋值为空，删除此行。

arm-linux-gnueabi-gcc编译器编译:
./configure --host=arm-linux-gnueabi CC=arm-linux-gnueabi-gcc --prefix=/home/book/work/toolchain_book/arm-gnueabi/minigui --with-ft2-includes=/home/book/work/toolchain_book/arm-gnueabi/freetype/include/freetype2 --with-hb-includes=/home/book/work/toolchain_book/arm-gnueabi/harfbuzz/include/harfbuzz --with-runmode=ths --enable-videoqvfb=no --enable-videortosxvfb=no --enable-videopcxvfb=no --enable-videodri=no --enable-jpgsupport --enable-pngsupport --enable-consoleial --with-targetname=fbcon LIBS="-lrt -lpthread" DFLAGS="-L/home/book/work/toolchain_book/arm-gnueabi/freetype/lib -L/home/book/work/toolchain_book/arm-gnueabi/harfbuzz/lib -L/home/book/work/toolchain_book/arm-gnueabi/jpeg-7/lib -L/home/book/work/toolchain_book/arm-gnueabi/libpng/lib" CPPFLAGS="-I/home/book/work/toolchain_book/arm-gnueabi/freetype/include/freetype2 -I/home/book/work/toolchain_book/arm-gnueabi/harfbuzz/include -I/home/book/work/toolchain_book/arm-gnueabi/jpeg-7/include -I/home/book/work/toolchain_book/arm-gnueabi/libpng/include"

8.minigui-res

step1:
./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc –prefix=/home/book/work/toolchain_book/arm/minigui-res

step2:
make
step3:
make install

9.libmgplus

FAQ:
Q1：
执行configure命令时报如下错误：
checking whether the C compiler works… no
configure: error: in /home/book/work/minigui/miniGui4.0/miniGui-core/libmgplus-1.4.0': configure: error: C compiler cannot create executables Seeconfig.log’ for more details

原因：CPPFLAGS=/xxx，必须接-I/XXXX

Q2：
In file included from path.h:63:0,
from path.cpp:51:
…/agg/font_freetype/agg_font_freetype.h:49:22: fatal error: ft2build.h: No such file or directory
#include <ft2build.h>
^
compilation terminated.

原因：ft2build.h头文件找不到
CPPFLAGS连接多个头文件的路径时后面的变量值用双引号包含，不可多次使用CPPFLAGS赋值，否则后面的值会覆盖前面的值。

Step1:

./configure --host=arm-linux-gnueabihf CC=arm-linux-gnueabihf-gcc --prefix=/home/book/work/toolchain_book/arm/mgplus PKG_CONFIG_PATH=/home/book/work/toolchain_book/arm/minigui/lib/pkgconfig CPPFLAGS="-I/home/book/work/toolchain_book/arm/minigui/include/ -I/home/book/work/toolchain_book/arm/freetype/include/freetype2/"

step2:

configure: error: in /home/book/work/minigui/miniGui4.0/miniGui-core/libmgutils-1.2.2': configure: error: C compiler cannot create executables Seeconfig.log’ for more details
遇到此问题时，先查看config.log信息。
