Gentle ping.

(In reply to Ondrej Dubaj from comment #1)
Hi Ondrej,

In https://download.copr.fedorainfracloud.org/results/odubaj/autoconf-2.70/fedora-rawhide-x86_64/02095342-fftw/ , we see that AC_CHECK_SIZEOF(size_t) fails for some reason.  Preceding checks for various integer types seem to pass.  An error was logged to config.log (probably the type isn't defined because a header isn't included?), but that artifact does not appear to be preserved.

I have a patch to try, but am not sure how to kick off a build with autoconf-2.71.  It looks like Rawhide is still on 2.69.  It builds with 2.69, but I don't know how meaningful that is.

Hi,

you can try building the package locally using mock. You can easily download mock config from our copr and try the build the package. Details here: https://fedoraproject.org/wiki/Changes/Autoconf_271#How_To_Test

Hi,

any updates here please ? Did you manage to test your patch ?

Thanks.

No update.

Hello, this issue does not seem to be resolved, can you please check it one more time ? Soonly we are planning to move to autoconf-2.71, so there will be FTBFS on this component.

Thank you.
