recompile with -fPIC

I'm having a trouble compiling perl module NET-SSLeay. I've openssl already configured with -fPIC. Below is the error I got from my 64bit CentOS architecture

Code:

[root@qmail Net-SSLeay-1.36]# perl Makefile.PL
Cannot determine perl version info from lib/Net/SSLeay.pm

/usr/bin/ld: final link failed: Bad value

make: *** [blib/arch/auto/Net/SSLeay/SSLeay.so] Error 1

Can anyone recommend a solution for this or atleast give me a right direction? Your help will be very much appreciated.

Why not do # yum install perl-Net-SSLeay

About openssl : It is quite unusual to have an extra openssl in /usr/local/.
Openssl is already installed. ( /lib64/libssl.so.0.9.8e etc.)
The command : 'rpm -qa | grep openssl' will show.

If you have no Internet, the packages can be found here :
http://mirror.centos.org/centos/5.6/os/x86_64/
http://mirror.centos.org/centos/5.6/

recompile with -fPIC

This means you only have the static libcrypto.a, libssl.a :
The shared libraries are required : libcrypto.so, libssl.so
→ → # yum install openssl-devel

I've already installed perl-Net-SSLeay from yum. But since the application I'm installing is from source, its also looking for perl modules generated from source. I've also installed openssl-devel but no luck.

Which application ?

Elv13 · 07-14-2011, 02:37 PM

CFLAGS=" -fno-PIC -fnoPIC"$CFLAGS" -fno-PIC -fnoPIC"
CXXGLAGS=$CFLAGS

export those variables and try again. If my syntax is right, it should turn off fPIC for your package and remove the dependency to OpenSSL fPIC objects.

ASSP

OK, ASSP. A new openssl is not required. Only a "local" perl-5.10.x.

Net-SSLeay-1.36 will build with no errors using the default 'CentOS 5'
openssl version. The openssl you have in /usr/local/ will not work.
Suggest : Start from scratch with Net-SSLeay-1.36 in a new directory.

Why are you typing # perl Makefile.PL ?
'perl' is /usr/bin/perl(5.8.8). I would expect $ /usr/local/bin/perl(5.10).
( Or whatever your location is for perl 5.10.x ).
And by the way: build commands are not to be run as root. Only 'make install'.

Other hints : The most perl modules can be installed with cpan.
Example : 1) su ; 2) /usr/local/bin/cpan ( The cpan from your perl 5.10 ).
3) cpan > install Text::Glob

Here's the solution for this.

Recompile openssl with shared attributes

./config shared
