    Gearman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。链接如下：http://search.cpan.org/~krow/Gearman-XS/

 

      我是在RHEL5.7下安装的Gearman::XS，中间出了各种问题，这里主要记录是怎么解决的。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，着手解决它。

vi Makefile

 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。

 

发现报如下错误：

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。
