Bug#335821: glibc: ftbfs [sparc] tls-macros.h:735:3: error: #error No support for this architecture so far.
Hi,
Please find attached a dpatch file to fix this bug. The code is taken
from upstream CVS. I still don't see why previous version of the glibc
were built successfully, the tls support was probably broken for them.
I am currently building a test version, but it takes very long as I am
building a lot of things at the same time on the machine. However, the
sparc-sparc64 flavour has already been built, so I suppose the build
will success. I will send you another mail to confirm that.
Bye,
Aurelien

I still don't see why previous version of the glibc were built successfully, the tls support was probably broken for them. I worked out before why this used to work, but I foolishly didn't write it down. It was complicated and took me a couple hours to work out :-) Ah, yes: * Merge makefile patch from Goswin Brederlow [EMAIL PROTECTED] to fail earlier if builds fail (but omit the bit for make -k check) (Closes: #325460). I believe we just failed to detect the error. Which didn't matter since this header is included only in testcases.

Yes... I have not quite figured out why this did not happen in the past, but it's pretty obvious why it happens now. We need to add sparc64 support to tls-macros.h and then it seems likely that will be enough to fix it. -- Daniel Jacobowitz CodeSourcery, LLC -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
