Today has been quite eventfull and productive for me . I finally found some success with my project . I am trying to port a software called OpenVPN .OpenVPN is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-control.
When I tried to build it from source I faced some difficulties getting the configure run. After a bit of research I got that working with the –disable lzo option . So this was the first dependency resolved for me . Then on doing make there was error compiling a file called tun.c . Researched again and found that for a 64 bit platform like open solaris I need to have the tun kernel module to compile the file tun.c and that to I had to make some changes inside the Makefile.in of the tun source adding the option -m64 for the 64 bit open solaris
Then I faced the error gcc not found while building the package tun 1.1 . As we kno gcc is not present by default in a Solaris system and is taken care of by Sun Studio compilers but the package in hand was hellbent on a gcc . So what I did is I again edited the file Makefile.in and replaced the CC entry with cc instead of gcc . Then it showed -Wall is an illegal option with cc so without thinking much I just removed it and crossed my fingers while making it and finally the tunnel driver was successfully installed and with the tunnel driver in the environment the dependencies of OpenVPN was also resolved .
Now it was the time for me making the Spec file from scratch for the OpenVPN source package. The preamble section was done easily without much trouble . Then I wrote the %prep section and kept it simple . Then there was the tough task of writing the %build section and I included all the dependency option of configure and with the help of someone in the mailing list I was able to write the %build section
%install was straight forward without any complicacies .
%file was the best . After lots of asking , mailing , head-scratching and research even that was done .
I kept my fingers crossed and executed pkgtool on the spec I wrote and guess what it passed .
Submitted my passed to the Source juicer site for the final test . It is still waiting to get validated may be by tommorow I will be able to see the results .
One important thing to be noted is that before submitting the spec to the juicer the license , vendor and copyright directives must be included as it is checked for also the .copyright file need to be uploaded along with the .spec file to the juicer . So the syntax check was done and it said OK .
Here is the spec I wrote :#OpenVPN (TM) — An Open Source VPN daemon

%description
OpenVPN is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls. Starting with the fundamental premise that complexity is the enemy of security, OpenVPN offers a cost-effective, lightweight alternative to other VPN technologies that is well-targeted for the SME and enterprise markets.
