Works perfect with DSM411slim and DSM 5.0-4458

Thanks!

Hi, same problem on my Synology DS213+ with DSM 4.2 (gcc 3.4.6, neon 0.29.6), but I found the following workaround (using http://download.savannah.gnu.org/releases/davfs2/davfs2-1.4.7.tar.gz):

> cd /volume1/@optware/powerpc-linux-gnuspe/lib
> mv libdl.so.2 libdl.so.2-old
> ln -s /lib/libdl.so.2 .
> cp /opt/bin/cpp /lib

create a new file /opt/lib/gcc/powerpc-linux-gnuspe/3.4.6/include/syslimits.h:
/* syslimits.h stands for the system's own limits.h file.
   If we can use it ok unmodified, then we install this text.
   If fixincludes fixes it, then the fixed version is installed
   instead of this text.  */

#define _GCC_NEXT_LIMITS_H              /* tell gcc's limits.h to recurse */
#include_next <limits.h>
#undef _GCC_NEXT_LIMITS_H

Then the compilation works:

> ./configure --prefix=/opt --with-neon=/opt
> make
> make install

Good luck,
Rainer

I´m facing the same problem. Same nas with DSM 4.0 and
gcc_3.4.6-5, neon 0.29.6-1. I a solution avaiable ?
@ Andreas - Do you resolved the problem ?

Thanks for all advices

Couldn't find the lines you mentioned.
I paste my complete config.log:

It was created by davfs2 configure 1.4.6, which was
generated by GNU Autoconf 2.61.  Invocation command line was

I have exactly the same issue:

As it is "the same issue" please do as Andrey in comment #2 and you will get the same result.

Otherwise:
What about some information:
Your system is not a standard Gnu/Linux system; I have no idea about the davfs2 version; your commandline; ...

Anyway: this looks like a problem very specific to your device/OS. Please check forums, HowTos and Help Desks for this specific device first.

Werner

I followed exactly the same instruction. But looks like something was wrong with packages installed. I've deleted ipkg and installed everything again and it works now.

Thanks for davfs2 and... sorry for bothering.

Can not I configure that with neon 0.29.3?
