problems running 16-bit code[solved]

[Adel Ahmed]

Whenever I try running one of my old games under wine I get the following error:
modify_ldt: Invalid argument
err:module:attach_process_dlls "krnl386.exe16" failed to initialize, aborting
err:module:LdrInitializeThunk Main exe initialization for L"C:\\windows\\system32\\winevdm.exe" failed, status c0000005

after some googling I found some people mentioning that some update in the linux kernel prevents running 16 bit programs under 64 bit cpus, they've also added that running:
#echo 1 > /proc/sys/abi/ldt16
will allow you to run 16-bit games

my question is:
bash: /proc/sys/abi/ldt16: No such file or directory
sys-kernel/gentoo-sources-3.12.21-r1:3.12.21-r1

what do I have to do to get 16-bit games to run again

Can you install a newer kernel? I'm on 3.15.6 and have the "/proc/sys/abi/ldt16" file. According to https://www.kernel.org/pub/linux/kernel/v3.0/ChangeLog-3.12.22 it says they added in support for it as a runtime option in 3.12.22 - which is a newer kernel then you have. I also skimmed some forums where it said it certain 3.13.0 versions had the security feature, but they had removed the runtime option.

http://bugs.winehq.org/show_bug.cgi?id=36664

Also suggest 3.12.21 will not work. There may be patches you can try, I didn't really dig that deep.

Seems like a waste..

This problem will be fixed for real in 3.16, once it's out - probably a couple weeks.

16bit? Isn't this something DosBox is for?

excellent, the new sources are working just fine for now
there are some 16 bit windows applications that cannot be run by dosbox

thanks everyone

wine devs, when prompted on this, said that many win32 programs before 64bit era had still 16bit installers.

[Adel Ahmed]

yup, that era, and it's not about being worth it, it's about old games/nostalgia
