Thanks for the link. I am most interested regarding *.rpm files as I have bought VariCAD, a biggish CAD package for Mechanical Engineering, the available *.rpm installed fine under pclos2009-kde also responded nicely to kpackage
but not so fine under pclos2010-kde. (lzma problem)
in this http://www.pclinuxos.com/forum/index.php/topic,72111.0.html
tested the "Viewer" (no licence required, so the customer can view the files from VariCAD, version for both Linux and Windows). muungwana
took the *.deb that is available too for VariCAD, and as I understand he knew that it was a matter of unpacking the content and try to install relevant parts in certain place(s) in the Linux Filesystem. He also got it very close to right because it ran.
I followed on using his idea and has almost got an install of the real VariCAD part requiring licence, I can only start the varicad
binary from Dolphin, not from konsole (that is my first experience with that) but I am really out on deep water here as I am doing a lot of guessing. The link you have given indicates something similar may be possible using *.rpm. I will follow up on that as far as I can. LinuxGnu I assume that he is aware of that his topic was transferred here my moderator (Neal) but I did put up the big warning above just in case.LinuxGnu
No the rpmlib(PayloadIsLzma) <= 4.4.6-1
this is not available
in Synaptic and as your search on the Forum no doubt has revealed pclos2010 has not at this stage support for this compression format. In the Linux world there seem to be a move to a later variant called "xz" which has some family relation with LZMA but now causes you and me and a few others a problem. Because we have chosen to go outside Synaptic, we are no longer held by the hand. Now we have to work hard shed tears and be frightened if we want to stay with pclos2010 to run our 'baby'.
Tell us what level of expertise you have with Linux. Are you expert with the underlying programming say compiling or even write you own programs of some form? You may be able to help solve this problem for a small number of users. Are you just a general user?http://linuxgazette.net/162/lindholm.html
I found some interesting history here worth a look.
My next step is to see if I can figure out how difficult *.rpm packing is I did have some good information on this on a nice partition which I accidentally erased so it is all over again. The link gseaman
gave above points me to some experimenting with unpacking like *.deb and perhaps this may solve my problem.
On forum there will be plenty of people that will point us in the right direction but
we have to do the hard work and risk our systems, therefore the red warning previously.
Your problem may be different in the end to mine, however follow the link I have given and read muungwana's
post and my own in same thread and see if that gives you any idea.
