Hi,
I'm also having the same problem as the topic creator. How would I link my project with the kernel libc?
Thanks |

This looks like a toolchain regression, probably in the newlib 1.15 patch.
ooPo, I'm having a bit of trouble following the newlib stuff currently in svn.
Did we stop using the drop-in trees for some reason? How do we modify and regenerate newlib-1.15.0.patch in that case? |

hi,
_times() function should be added to a seperate file (syscalls.c ?!). anyway here is a quick and ugly workaround....

Uhm, I hadn't seen much activity with it so I assumed it wasn't really useful for people. I had been planning to just merge new patches manually.
So no real good reason, at least. We can certainly go back to using the trees if you like. :) |

I've merged this into newlib-1.15.0-PSP.patch in the repository. |

Ugh, pipe.c is definitely not the right place for that :P
If we're not using drop in trees (which is fine with me), we should delete it from the repository. Maybe a readme describing how to regenerate the patch would be useful. I don't know the best way, maybe: Unpack newlib, make a copy, apply the psp patch, make edits, then diff the two copies? |

Perhaps pipe.c is a bad place for it, but until a better place is decided we have working code. It is a small change that can be easily removed later.
In the meantime, I'll do up a howto for making patches and how to submit them. |

| i would like to pute _times(..) to a seperated file syscalls.c but there is something with my autoconf, version mismatch i think. when i generate .in and configure files with autotools ./configure gives strange errors in newlib. |
