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。
