I think your statement (quoted below) is slightly incorrect.

The GPL FAQ here: http://www.gnu.org/licenses/gpl-faq.html#LinkingWithGPL

Clearly states:

... you must release your program under a license compatible with the GPL (more precisely, compatible with one or more GPL versions accepted by all the rest of the code in the combination that you link).

Granted, "compatible with GPL" does not mean it must be GPL, but it must carry on the "Freedom" of GPL.

I don't think PCMAV's license is GPL-compatible, as they do not provide their source code at all.

If you mix GPL code in with your own code, then yes, you are obligated to release those modifications sourcecode. However, if your code just links to GPL code, you are under no such obligation.

Unfortunately, it is a closed source software(i think). coz, this AV is only distribute as a bundle with the magazine. Even we can't get the AV from their website. I don't think they have will to release the sourcecode.

If you release sourcecode for PCMAV it will not violate.

Okay, thanks for the pointer.

Problem is, I am not the programmer of the program in question. But the issue of whether the program violates the GPL or not is still a

polemic

my place.

The program is called PCMAV, and the program can be downloaded here: (each link a different version of the program) http://rapidshare.com/files/130842014/PCMAV-1.5.zip http://rapidshare.com/files/123822011/PCMAV-1.4.zip http://rapidshare.com/files/116129695/PCMAV-1.3.zip http://rapidshare.com/files/109574110/PCMAV-1.2.zip

The program is a freeware, *but* does not use GPL.

Now, based on the instructions here: (in Indonesian language, I'll explain below)

http://maseko.com/2007/09/21/pcmav-kenali-lebih-banyak-virus-dengan-library-clamav-09x/

In essence, the instructions say: To integrate PCMAV with ClamAV, all you have to do is to copy the files libclamav.dll, libclamunrar.dll and libclamunrar_iface.dll, along with the latest databases main.cvd and daily.cvd into the same folder where PCMAV is installed.

Now, we are at an impasse; some say PCMAV is violating the GPL. Others say it is not. Based on the above, what's your take on PCMAV?

I hope to have a definitive answer so that we can put the question to rest.

Thank you for your help.

Rgds,

My question is: If I create a program that can *optionally* use

libclamav,

must that program be GPL-licensed as well?

The short answer is "no", there is no obligation for the new program

licensed under the GPL. The creation of a program that optionally makes function calls to a program licensed under the GPL should not create an obligation to distribute

the

new

program under the GPL.
