I use phing as a deployment tool on CentOS and I'd like to use the SshTask, which required libssh2 to be installed.

I tried "pecl install ssh2" but that asks me for a libssh2 prefix [/usr?]

I noticed that this means I need to install libssh2 first, but yum does not have that package. So my question is: what is the best way to install libssh2 on Centos and then install the pecl extension?

to install libssh2 on centos follow the next steps:

  1. download libssh2 from the official website (look for in google - i don't have reputation and can't post but 1 link)

  2. extract it somewhere, then open a terminal and go in the folder where you extracted it and type these commands

    ./configure
    
    
    make
    
    
    make install
    

ALSO

you can install the rpmforge repos from DAG from here:

http://dag.wieers.com/rpm/packages/rpmforge-release/

(check your version, if you're on i386 you'll probably have to get the "Red Hat EL 5 - i386" one)

then do a

yum install libssh2

thanks, perfect info. Now when I'm installing "pecl install ssh2" it asks "libssh2 prefix? [/usr]". Is that ok, or should it be "/usr/lib/libssh2.so.1"? [user@centos deployment]# rpm -ql libssh2 /usr/lib/libssh2.so.1 – solsol Jun 2 '10 at 21:48
    
no matter what I type there, it says: configure: error: The required libssh2 library was not found. You can obtain that package from sourceforge.net/projects/libssh2 ERROR: `/tmp/pear/download/ssh2-0.11.0/configure --with-ssh2=/usr/lib/libssh2.so.1' failed – solsol Jun 2 '10 at 21:49

solved: it needed this: yum install libssh2-devel – solsol Jun 2 '10 at 21:56
    
except for new errors: running: make /tmp/pear/download/ssh2-0.11.0/ssh2.c:1104: warning: passing argument 4 of 'add_assoc_stringl_ex' discards qualifiers from pointer target type /tmp/pear/download/ssh2-0.11.0/ssh2.c:1105: warning: passing argument 4 of 'add_assoc_stringl_ex' discards qualifiers from pointer target type make: *** [ssh2.lo] Error 1 ERROR: `make' failed – solsol Jun 2 '10 at 21:58

You need libssh2-devel not just libssh2. Here's a little shorter version

yum install libssh2-devel
pecl install ssh2-0.12

No package libssh2-devel available. when trying to install libssh2-devel – vladkras Jan 8 at 14:04
    
@vladkras which version of CentOS/RHEL and which repositories do you have installed (EPEL? Remi? etc)? – Eric Kigathi Jan 12 at 8:18
    
I have CentOS 6 and remi repo, check my answer for more info – vladkras Jan 12 at 14:11

If you have "remi" repository, it provides php-pecl-ssh2, no need to build anything. – Remi Collet Jan 12 at 14:57

Effort to install libssh2-devel using yum failed with error No package libssh2-devel available. (remi repo)

I downloaded it from PECL website and installed via

# pecl install -f packagename.tgz

All other packages and dependencies were downloaded from rpmfind.net and installed like this

# rpm -ivh packagename.rpm
