NPTL on OMAP 5912

NPTL on OMAP 5912

[Richard Copeman]

Hi,

 

I have a 2.6.15 kernel running on my 5912OSK board. Has anybody got the NPTL
stuff working on here? Can someone point me at a getting started guide?

I tried to figure out which version of threads my target supports:

            Getconf GNU_LIBPTHREAD_VERSION

 But the command returned an empty string :-(

I built my target with GCC 3.4.1 which I built using crosstool.

 

Thanks,

 

Richard.

Hi,

Thanks for the pointers. Which shared objects do you include in your target
filesystem?

TIA,

Richard.

I used hacked version 0.38 to build NTPLed toolchains. If you are not
familiar with building toolchains you may want to use precompiled ones:

That's not enought recent gcc (unless you are using codesourcery patches).
I'm using gcc-4.1.1, glibc-2.4 and binutils-2.17 sucessfuly.

Depends on what you want to run. You may need more or less, it's easy to
control it with PTXdist :-)
