We're blocking on openblas, which is blocking on a bug involving ppc64le.

Thanks for diving onto the issue.

Rebuild should be finished soon…

Comment 4 Björn Esser (besser82) 2017-02-13 23:45:39 UTC

Build now fails for:

> configure: WARNING: unrecognized options: --disable-dependency-tracking
> configure: error: zlib library and headers are required
> RPM build errors:

From the logs, for instance [1], you are using the R-3.3.2.tar.gz sources. Since that release, there have been a zlib bug fix :

* commit: https://github.com/wch/r-source/commit/a0fe05ce9d0937ad2334bb370785cb22c71e592b

* changelog: https://cran.r-project.org/doc/manuals/r-devel/NEWS.html
“INSTALLATION on a UNIX-ALIKE
The configure check for the zlib version is now robust to versions longer than 5 characters, including 1.2.10.
”

The relevant version is R-patched 3.3.2 [2]. You are maybe hitting that same zlib bug and building from the patched sources might be the right way to go.
