Error building with external toolchain

Hi all,

I'm having some trouble getting buildroot to import my external toolchain properly. The output is:

to target...
make[1]: *** [/home/dgale/Documents/system_build/bld/start.buildroot-2013.11/output/build/toolchain-external-undefined/.stamp_staging_installed] Error 255
make[1]: Leaving directory
`/home/dgale/Documents/system_build/bld/start.buildroot-2013.11'
make: *** [.buildroot] Error 2

I have been unable to get make to output any useful error messages here, even using the -d flag.

This error shows release 2013.11, but there are similar problems with the latest git snapshot.

What is the problem here? Has anybody run into this before? I should mention that the toolchain being imported is 64-bit. This is NOT an issue using an equivalent toolchain at 32-bits. The 64-bit toolchain, however, doesn't support multilib.

What will be required to get buildroot working with the 64-bit toolchain?

Thanks,
Danny

Dear Danny Gale,

Interesting. Can you show your Buildroot .config file, and give more details about what your external toolchain is (or even better, provide us this external toolchain so that we can potentially reproduce the problem) ?

Hum, the order of your messages look weird: the last message shown is "Copying external toolchain libraries to target", but make reports that the error occurred while working on the .stamp_staging_installed target. Maybe it's just me misinterpreting the output of make, I don't know.

Aren't you running with "make -j<something>" by any chance?

When you're talking about 32 bits or 64 bits, are you talking about the bitness for the host architecture, or the target architecture?

Thomas, list:

I'm running make with a single thread (-j1) to pinpoint this error.

The external toolchain was built on an x86_64 host by Crosstool-NG 1.19.0 for a powerpc64-e6500 target. I've attached the config file for ct-ng.

I was able to go through the buildroot source and follow it through: the .stamp_staging_installed target calls $($(PKG)_INSTALL_STAGING_CMDS), with PKG=TOOLCHAIN_EXTERNAL. TOOLCHAIN_EXTERNAL_INSTALL_STAGING_COMMANDS in ./toolchain/toolchain-external/toolchain-external.mk calls TOOLCHAIN_EXTERNAL_INSTALL_CORE in that same file. The message "Copying external toolchain libraries to target..." is there, though I don't understand why it fails at that point.

It seems I was mistaken -- the 32-bit version of the toolchain doesn't seem to import either. A different 32-bit toolchain (for the powerpc 440 core) does import, however. So there seems to be something wrong with my toolchain configuration. I suspect RPC support to be the culprit.

The target. The host is an x86_64. The target is a 64-bit powerpc (e6500 core)

Dear Danny Gale,

Ok. Can you put up online a tarball of this toolchain?

We don't have powerpc64 support in Buildroot, so maybe some minor changes in the external toolchain logic are needed.

Correct. All the external toolchain logic is in toolchain/toolchain-external/toolchain-external.mk.

Again, if you can sure the toolchain tarball, I could do some testing.

Thanks!

Here's an RPM of the toolchain to run on x86-64 host that will install to /opt/start64TC (54 MB download)

Thanks,
