下载 mpfr gmp mpc

安装mpfr

./configure --prefix=/usr/local

安装gmp

./configure --prefix=/usr/local

安装mpc

./configure --prefix=/usr/local

导出库路径 

    ~/.bashrc修改库加载路径 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

    在 /etc/ld.so.conf里添加库路径/usr/local/lib，保存退出后执行命令 

sudo ldconfg

    退出终端重进

安装 glibc.i686 glibc-devel.i686 （64位机器上没有32位glibc库和头文件，会报找不到头文件gnu/stubs-32.h的错误）

sudo yum install glibc.i686 glibc-devel.i686

上面这些都做好了登出重新登录一下

把gcc-4.6.2.tar.gz 移动到 codeviz-1.0.12/compilers 目录下

把 codeviz-1.0.12/compilers/install_gcc-4.6.2.sh 这几行修改一下就能让这里构建通过，主要是添加 --disable-bootstrap

-INSTALL_PATH=$HOME/gcc-graph

+INSTALL_PATH=/usr/local/gcc-graph

-../gcc-4.6.2/configure --prefix=$INSTALL_PATH --enable-shared --enable-languages=c,c++ || exit

-make bootstrap+CFLAGS="-O2 -fPIC" ../gcc-4.6.2/configure --prefix=$INSTALL_PATH --disable-bootstrap --enable-shared --enable-languages=c,c++ || exit+make -j 4

回到目录 codeviz-1.0.12 执行命令

./configure --gccgraph=/usr/localmakesudo make install

安装成功：

*** CodeViz is now installed to  and testsuites passed ***

Patched gcc is installed to /usr/local. To compile a project

for use with CodeViz, genearlly the following will work

make CC=/usr/local/bin/gcc or g++

To generate a full.graph file for C, use

genfull

For C++, make sure you use the cppdepn method with

genfull -g cppdepn

or the results will not be what you expect.

编译生成 *.cdepn文件

make

生成full.graph文件

genfull -g cppdepn

生成图片

gengraph --output-type "png" --output-layout "LR" -d "10" -f "main"
