Hi All, I has been trying to port the Samba package to uClinux. But our uClinux toolchain doesn't support the fork() call. I must replace the fork with vfork.If we use vfork, the smbd and nmbd can not work rightly. both samba-3.0.32 and samba-3.0.2a have the question. In samba/source/smbd/server.c, the function open_sockets_smbd(), creates a child process and a parent process. Both these

Hello all, I really want to support vfork() in klibc, mostly because uClinux *has* to use it. Unfortunately vfork() isn't allowed to use the stack *at all* across the system call -- including return address -- which means it needs an assembly wrapper on most architectures. I have tried implementing wrappers for most architectures, but I don't know parisc or s390/s390x well enough,

Hi klibc people, if someone has to say more on this, please do so. I?m only trying to explain what I _think_ I learned? >Begin forwarded message originally by Mike Frysinger: >> On Mon, Mar 21, 2011 at 10:24 AM, Waldemar Brodkorb wrote: >>> unfortunately the common vfork implementation, which just use >>> the syscall function to interact with the kernel, does not

Hi all, I just built R from src on Windows 7 using Rtools212.exe. The build went as usual (R, bitmaps, and manuals all OK) but make check-all failed when running the examples for package 'tcltk': ... running code in 'demos2.R' ... OK running tests of primitives running code in 'primitives.R' ... OK make[2]: vfork: Resource temporarily unavailable make[1]: ***

Use klibc way to define a system dependent preprocessor definition: disabled by default and enabled for newer arm. Based on a patch by vorlon that got tested on his beagleboard, should be functional equivalent.
