Gearman::XS在Centos下的编译安装方法
本文简述了gearman::xs在centos下编译安装方法,供大家参考学习一下!
目前gearman能够支持各种语言,其官网的描述如下:
language bindings/drivers/frameworks select your language – cross links to download section which details all your options. c, c#/.net, go, java, lisp, nodejs, php, perl, python, ruby, database udfs.
个人尝试了c、python、perl三种语言的api,感觉perl的api功能相对来说齐全一点。gearman::xs是perl的开源支持。其链接如下:http://search.cpan.org/~krow/gearman-xs/
在rhel5.7下安装的gearman::xs,中间会出现各种问题,此处给出这些问题的解决方法供大家参考。
首先,我使用了cpanm来安装gearman::xs,结果如下:
[@localhost yunfei]# cpanm gearman::xs --> working on gearman::xs fetching http://www.cpan.org/authors/id/k/kr/krow/gearman-xs-0.15.tar.gz ... ok configuring gearman-xs-0.15 ... ok building and testing gearman-xs-0.15 ... fail ! installing gearman::xs failed. see /root/.cpanm/work/1392343258.18128/build.log for details. retry with --force to force install it.
显然force强制安装肯定是不行的,所以就找原因。查看 /root/.cpanm/work/1392343258.18128/build.log文件,发现其中有如下的提示:
gcc -c -wall -wundef -wno-shadow -wmissing-prototypes -fdiagnostics-show-option -wformat=2 -wstrict-aliasing -wextra -wmissing-declarations -wcast-align -wswitch-default -wswitch-enum -wno-undef -wno-unused-value -wno-unused-variable -wno-unused-parameter -wno-format-invalid-specifier -o2 -g -pipe -wall -wp,-d_fortify_source=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -dversion=\"0.15\" -dxs_version=\"0.15\" -fpic "-i/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/core" xs.c cc1: error: unrecognized command line option "-wno-format-invalid-specifier" make: *** [xs.o] error 1 -> fail installing gearman::xs failed.
看到是在编译的时候出了问题,所以,咱们切换到它的编译目录(即 /root/.cpanm/work/1392343258.18128/这个目录)
cd /root/.cpanm/work/1392343258.18128/gearman-xs-0.15
然后执行make命令,就可以看到上面报的编译错误了。ok,下面就着手解决它。
vi makefile
可以找到:
ccflags = -wall -wundef -wno-shadow -wmissing-prototypes -fdiagnostics-show-option -wformat=2 -wstrict-aliasing -wextra -wmissing-declarations -wcast-align -wswitch-default -wswitch-enum -wno-undef -wno-unused-value -wno-unused-variable -wno-unused-parameter -wno-format-invalid-specifier
删掉最后的“-wno-format-invalid-specifier”这个选项,然后保存退出,再次执行make。
会发现报出如下错误:
in file included from xs.xs:11: gearman_xs.h:18:36: error: libgearman-1.0/gearman.h: no such file or directory xs.c: in function 'xs_gearman__xs_strerror': xs.c:229: error: 'gearman_return_t' undeclared (first use in this function) xs.c:229: error: (each undeclared identifier is reported only once xs.c:229: error: for each function it appears in.) xs.c:229: error: expected ';' before 'rc' xs.xs:82: warning: implicit declaration of function 'gearman_strerror' xs.xs:82: error: 'rc' undeclared (first use in this function) xs.xs:82: warning: assignment makes pointer from integer without a cast make: *** [xs.o] error 1
很明显,是找不到gearman.h,也就是说需要gearman-devel,正常情况下通过yum直接安装gearman-devel包就可以解决这个问题,但是,我的rhel是手动安装的gearman-1.1.11版本,和yum安装的版本不一致,所以,再次打开并修改makefile。
找到inc以及lddlflags,修改为如下内容:
lddlflags = -shared -o2 -g -pipe -wall -wp,-d_fortify_source=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -l/usr/local/gearman/lib/ -lgearman inc = -i/usr/local/gearman/include/ -l/usr/local/gearman/lib/
可以看到就是加入了gearman的incule以及lib相关的东西。保存退出makefile,再次执行make,顺利通过,然后make install就安装完毕了。
