Centos手动编译安装vim8

系统：CentOs6.9

gcc版本：5.1.0

github上拉取vim工程之后，cd src，执行一下命令：

$ ./configure
$ sudo make
gcc -c -I. -Iproto -DHAVE_CONFIG_H     -g -O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1        -o objects/arabic.o arabic.c
gcc: error trying to exec 'cc1': execvp: No such file or directory
make: *** [objects/arabic.o] Error 1

发现找不到cc1。全局找下cc1在哪：

$ sudo find / -name cc1
/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/5.1.0/cc1
/usr/libexec/gcc/x86_64-redhat-linux/4.4.4/cc1
/root/software/gcc-5.1-build/gcc/cc1
/root/software/gcc-5.1-build/stage1-gcc/cc1
/root/software/gcc-5.1-build/prev-gcc/cc1

建立一个软连接：

$ sudo ln -s /usr/local/libexec/gcc/x86_64-unknown-linux-gnu/5.1.0/cc1 /usr/bin/cc1

重新编译一下：

$ sudo make
gcc -c -I. -Iproto -DHAVE_CONFIG_H     -g -O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=1        -o objects/arabic.o arabic.c
In file included from os_unix.h:21:0,
                 from vim.h:246,
                 from arabic.c:16:
/usr/include/stdio.h:34:21: fatal error: stddef.h: No such file or directory
compilation terminated.
make: *** [objects/arabic.o] Error 1

发现还是有问题，而且这个报错报在了库文件

全局找下这个文件：

$ sudo find / -name stddef.h
/usr/local/lib/gcc/x86_64-unknown-linux-gnu/5.1.0/include/stddef.h
/usr/include/linux/stddef.h
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/include/stddef.h
/root/software/gcc-5.1-build/gcc/include/stddef.h
/root/software/gcc-5.1-build/stage1-gcc/include/stddef.h
/root/software/gcc-5.1-build/prev-gcc/include/stddef.h
/root/software/gcc-5.1.0/gcc/ginclude/stddef.h
/root/software/gcc-5.1.0/libstdc++-v3/include/c_compatibility/stddef.h

发现是能找到，不过报错的文件的位置，是/usr/include/stdio.h，感觉是路径问题了。

尝试用sudo权限运行./configure：

$ sudo ./configure
configure: loading cache auto/config.cache
checking whether make sets $(MAKE)... (cached) yes
checking for gcc... (cached) gcc
checking whether the C compiler works... no
configure: error: in `/home/haiming.li/opensource/vim/src':
configure: error: C compiler cannot create executables
See `config.log' for more details

同样通过find命令，找到config.log所在的位置是src/auto下面，打开看看：

感觉很莫名的报错，而且为何sudo与非sudo执行的时候结果差别那么大呢？

猜测是sudo的gcc跟非sudo下的gcc，版本不一致，尝试验证下：

$ which gcc
/usr/local/bin/gcc

$ sudo which gcc
/usr/bin/gcc

果然，sudo和非sudo下，gcc调用的执行程序不一样。/usr/local/bin/gcc --version 和 /usr/bin/gcc --version的执行结果是一样的，这个比较莫名。不过如果做下软连接，我相信能解决问题。

先对原来的/usr/bin下的gcc做下备份：

$ cd /usr/bin/
$ sudo mv gcc gcc_bak
$ sudo ln -s /usr/local/bin/gcc gcc

继续：

$ ./configure
$ sudo make

然后报了类似这样的错误：

/opt/local/bin/gcc-mp-4.8 -c -I. -Iproto -DHAVE_CONFIG_H   -I/usr/local/include  -g -O2 -D_FORTIFY_SOURCE=1       -o objects/buffer.o buffer.c
In file included from vim.h:302:0,
                 from buffer.c:28:
auto/osdef.h:18:12: error: conflicting types for 'printf'
 extern int printf __ARGS((char *, ...));

google之后，只发现了一个日文网页，而且说得好像不是一个问题，灵机一动下，make clean了一下，然后make就通过了，接着

$ sudo make install

执行下vim：

$ vim
-bash: /usr/bin/vim: No such file or directory

在编译日志里面找了找，感觉vim应该是在/usr/local/bin/vim：

$ /usr/local/bin/vim --version
VIM - Vi IMproved 8.1 (2018 May 17, compiled May 28 2018 15:26:31)
Included patches: 1-22...

果然在这里，做下软连接：
$ sudo ln -s /usr/local/bin/vim /usr/bin/vim

OK，大功告成，手动编译vim8.1搞定。
