Request OpenBLAS development libraries for fastPLS build machines

[tkcaccia]

Package information

• Package: fastPLS
• Repository: https://github.com/tkcaccia/fastPLS
• Status: under Bioconductor submission
• Version exhibiting the problem: 0.99.61
• Commit: 34a4da1ff0068e11654d96b147a3b0bbaa2bbec8

System requirement

fastPLS requires an OpenBLAS development library on Linux and Windows.

The package uses single-precision BLAS routines, including ssyrk. These
routines are not necessarily available from R's internal reference BLAS.
Without OpenBLAS, the package either fails during configuration or produces
a load-time error such as:

unable to load shared object 'fastPLS.so':
undefined symbol: ssyrk_

Linux build machines

The development package has different names across Linux distributions.
For Debian and Ubuntu:

apt-get update
apt-get install -y libopenblas-dev pkg-config

For Fedora and RHEL-compatible distributions:

dnf install -y openblas-devel pkgconf-pkg-config

The package detects the installation through:

pkg-config --cflags openblas
pkg-config --libs openblas

It also supports OPENBLAS_ROOT for installations in nonstandard locations.

Windows build machines

The Windows build requires OpenBLAS headers and a static OpenBLAS library
compiled with the same Rtools UCRT toolchain and architecture used by the
Bioconductor builder.
The library must provide the required single-precision BLAS routines,
including ssyrk.
Could you please advise whether an Rtools-compatible OpenBLAS library can be
made available on the supported Windows builders? If different arrangements
are needed for x86-64 and ARM64, guidance on the preferred Bioconductor
mechanism would be appreciated.

Package metadata and documentation

The package declares the dependency in DESCRIPTION using a
distribution-neutral description:
SystemRequirements: OpenBLAS development library providing single-precision
BLAS routines; pkg-config on Unix
A top-level INSTALL file documents the corresponding installation commands
for supported operating systems.
The package configuration checks, in order:

1. OPENBLAS_ROOT;
2. pkg-config openblas;
3. standard system library locations.
   Installation stops with an explicit diagnostic when the mandatory dependency
   cannot be found or does not pass the compile-and-link test.

Reproducible failure

An R-universe Bioconductor-staging build failed because the OpenBLAS
development package was unavailable:
https://github.com/r-universe/biocstaging/actions/runs/34610953660
The relevant message was:

ERROR: OpenBLAS is required for this fastPLS Linux build but was not found.
Install the OpenBLAS development package and pkg-config, or set OPENBLAS_ROOT.
ERROR: configuration failed for package 'fastPLS'

I understand that R-universe is separate from the official Bioconductor Build
System. This run is provided only as a reproducible example of the missing
system dependency.

Request

Could the following dependencies please be made available on the
Bioconductor build infrastructure?

• Debian/Ubuntu Linux: libopenblas-dev and pkg-config.
• Fedora/RHEL Linux: openblas-devel and pkgconf-pkg-config.
• Windows: an OpenBLAS static library and headers compatible with the
  corresponding Rtools UCRT toolchain and architecture.
  Please let me know if additional configuration logs, symbol checks, or
  platform information are required.
