Hi, I’m new to Kdb+/q. I downloaded the 32-bit free version from the kdb+ website to install on my 64-bit Arch Linux System. I am getting a problem with trying to launch the ‘q’ executable under q/l32/q. I keep getting a message indicating  ?  ~  cd q ?  q  rlwrap l32/q “$@” rlwrap: Cannot execute l32/q: No such file or directory The executable is there. When I do an ‘ls l32/q’ the system picks it up, but anytime I try to execute I get the above no such file message. I’m probably not doing something simple here but I cannot see it. Any help would be appreciated. I tried on my Mac and all is good there so not sure why it is not working on my Linux box. ---

you might be missing 32bit libs from the system. try sudo apt-get install ia32-libs ---

Thanks. I don’t think I will be able to run the 32-bit version of kdb+ on my Arch Linux 64-bit machine. In Arch Linux, there is a multi-lib setting (equivalent to ia32-libs in Ubunutu) which can be enabled which should theoretically setup up a 32-bit environment (within a 64-bit one) so that 32-bit apps can be run. I did this and updated my system but it still doesn’t work. ---

Hi Iftikhar, How did you get on with this in the end? I had the same problem and had to run other commands before Charles’ command. I basically just did everything on this page(you might have already seen the page, maybe not)… [http://stackoverflow.com/questions/23182765/how-to-install-ia32-libs-in-ubuntu-14-04-lts](http://stackoverflow.com/questions/23182765/how-to-install-ia32-libs-in-ubuntu-14-04-lts) I was installing 32 bit q on 64 bit ubuntu so I thought this may be of help to you if you never solved it. Hope it helps. Sean ---
