Thank you! Installing openblas and then using ./configure --without-lapack --with-blas --enable-R-shlib
..got everything working. Does this need reporting upstream as a bug in R or lapack? I'm good now, but it might help others to get this fixed.

I figured out I needed to enable the "PowerTools/CRB" repo, installed lapack-devel from there, and now I get the same configure output and the same crash: by linking with R's built-in Rblas but and system-provided LAPACK-3.9.0. If I configure --without-lapack, i.e. use both Rblas and R-provided functions from LAPACK up to 3.12.0, the build doesn't crash. If I try to enable --with-blas=-lblas, here's what happens: configure:47862: checking whether double complex BLAS can be used configure:47946: result: no The test compares the result of the BLAS function zdotu with the manually computed vector norm for a complex vector [*]. In this case, the Fortran program thinks that the BLAS returns a zero instead of the correct answer, thus failing the test and refusing to compile with system BLAS. I think that you somehow stumbled upon a Fortran ABI incompatibility regarding passing complex numbers between the Fortran code compiled during R build and the BLAS and LAPACK provided in the PowerTools/CRB repo. I don't know what exactly is the problem, but at least --without-lapack is an easy workaround without any cost in performance. In fact, if you install openblas-devel and configure --with-blas (to replace Rblas with OpenBLAS), the double complex BLAS test will pass, the build won't crash, and you will get even better performance. -- Best regards, Ivan [*] https://stat.ethz.ch/pipermail/r-devel/2024-March/083302.html ------------------------------------ This email has been scanned for spam & viruses.
