ccache是加快编译的神器,有了ccache,忘了distcc。但是发现go和c混编的项目里面如果用了cgo的话,go编译的时候ccache会报错。主要是传给ccache的某些参数ccache不认识。错误如下:

/usr/bin/ccache: invalid option -- 'd'
Usage:
    ccache [options]
    ccache compiler [compiler options]
    compiler [compiler options] (via symbolic link)

Options:
    -c, --cleanup delete old files and recalculate size counters
                          (normally not needed as this is done automatically)
    -C, --clear clear the cache completely
    -F, --max-files=N set maximum number of files in cache to N (use 0 for
                          no limit)
    -M, --max-size=SIZE set maximum size of cache to SIZE (use 0 for no
                          limit; available suffixes: G, M and K; default
                          suffix: G)
    -s, --show-stats show statistics summary
    -z, --zero-stats zero statistics counters

    -h, --help print this help text
    -V, --version print version and copyright information

之前都是关了ccache,后来想新的版本能不能搞定呢?有人提了Issue但是没看到release上有啥新的fix。直接升了一下版本:

wget https://www.samba.org/ftp/ccache/ccache-3.2.5.tar.bz2
bunzip2 ccache-3.2.5.tar.bz2
tar xvf ccache-3.2.5.tar
cd ccache
./autogen.sh
./configure
make -j 8
yum install asciidoc
make install

然后export set CC=‘gcc ccache’,再重新automake就行了。

但是发现还是一样。后来想可以用shell包一层啊,看网上有相应的方案:

 #!/bin/bash
 ccache gcc "$@"

保存这个到path路径下,改名ccached之类,export set CC=ccached,貌似这样ccache不认识的参数就不传递了?反正是ok了,改天研究下。
