Hello,
under some circumstances the following small example prints lots of
garbage onto the console and into the syslog:
#include <syslog.h>
int main ()
{
openlog("foo", LOG_CONS|LOG_NDELAY|LOG_PID|LOG_PERROR, LOG_DAEMON);
syslog (LOG_WARNING, "mlock: %m");
return 1;
}
The reason is, that sprintf returns with -1 and vsyslog dumps the
complete buffer onto stderr and the syslogd socket. The following
patch would fix the problem:
|
|
Remove use of cast-as-l-value extension, removed in GCC 3.5.

uClibc resolver doesn't lookup all search domains.
For example, if you have computer 'jenda.prague.my.cz' and resolv.conf:
search my.cz
nameserver xx.xx.xx.xx
try this:
ping jenda.prague.my.cz #works
ping jenda.prague #unknown host
libc/inet/resolv.c doesn't want to try search domains if the domain name
contains '.'. I don't find any reason for the behaviour in literature
and it is inconsistent with the glibc.
Patch is attached.
regards,
- jenda

I then reworked the syscall handling and made minor cleanups. With luck
I've not completely broken his patch...

Most of the time, no one ever notices, so there's not point eh ? Also
standardize tab usage.

Here is a small patch to add epoll support to uclibc.
The only thing I am not sure about is what needs to be done (if anything)
to make it work on 2.4/2.2 kernels (are the syscall numbers defined but
give errors when called or not?).
Tested on 2.6, though some other issues prevent more extensive testing at
the minute.
Mike Frysinger:
cleaned up patch and added checks to make sure that the syscall actually
exists, returning ENOSYS in cases where it doesn't.

here are few patches for better compatability in ./Makefile:
cp.diff - use portable (POSIX) way to specfic --no-dereference (-d)
|
|
here are few patches for better compatability in ./Makefile:
make.diff - make should never called directly, change it to $(MAKE)

'buildroot', which can do everything 'toolchain' could do and then
some. And is actively maintained.

The Arm crt0.S contains non-PIC code for locating _init and _fini sections.
This caused problems on my uclinux system when static constructors were
enabled.
The attached patch implements a PIC version of this code.

Here's an updated version of the patch I posted about a month ago. It
leaves -nostdinc alone, and uses -print-file-name=include instead of
-print-search-dirs to figure out where GCC's internal headers are.
Please let me know whether there are any portions of this patch you'd
like me to break into smaller pieces, to rework, or to give up trying
to get into uClibc :-) Thanks,

libthreaddb must not be stripped or gdb can't use it.
