Compilation failure for MIPS64: __NR_getdents64 is undefined

[GoogleCodeExporter]

I'm using the Buildroot distribution (http://buildroot.busybox.net/) and I'm 
trying to build a filesystem for MIPS64 n64 LittleEndian with the package 
"google-breakpad" included.

This is snippet of the compilation error (the full build log is attached):

http://buildroot.busybox.net/ doesn't load...

How can I get a mips64 Linux system to test this? With QEMU/KVM perhaps?

Hello, and thanks for your answer.

The buildroot website works fine for me. Anyway, this is the command to clone 
the repository:

git clone git://git.buildroot.net/buildroot

or if you're behind a firewall blocking git:

git clone git://git.buildroot.net/buildroot

Buildroot will crosscompile, so you don't need a MIPS64 Linux system to 
reproduce the failure. Buildroot is a tool to generate embedded Linux systems 
by crosscompiling, and let you choose the target architecture. So, the steps to 
reproduce the failures are:

-clone the Buildroot repository
-type "make menuconfig" and go to the "Target options" menu.
-choose "MIPS64 Little Endian" target architecture.
-choose "n64" target ABI
-go to the "Toolchain" menu and select "External toolchain" type.
(that will download a toolchain, so you will save time by not building a 
toolchain to generate code for your selected target)
-go to "Target packages" -> "Debugging, profiling and benchmark" and select the 
"google-breakpad" package.
-exit and save your configuration
-type "make"

And just to answer your question. Yes, QEMU/KVM works if you want to emulate a 
MIPS64 Linux system.

Can you try the attached patch?

Hello,

the patch you attached doesn't work directly on Buildroot, so I needed
to rewrite it. I have attached the new patch just in case you want to
review it. I think I haven't done any mistake.

It fails with the same problem. I have attached the full build log.

Actually, this problem went away. You have different problems in the comment 5 
build.log, which are outside of the scope of this bug. (Back to Breakpad...)

Is this still a valid issue or should we close it?
