Subject: [PATCH 1/1] CMake/FindCBLAS.cmake: search only for cblas
|
|
|
|
On Gentoo, users can "eselect cblas" to choose a cblas implementation
|
|
at runtime. Packages build against the reference cblas, but the others
|
|
are (by design) compatible, so we can force one to take precedence at
|
|
runtime with an ld.so.conf entry. But that only works when consumers
|
|
link to libcblas.so. If they link directly to (say) openblas, then
|
|
changing how libcblas.so resolves won't help.
|
|
|
|
When Flint tries to find "cblas," it looks for accelerate and openblas
|
|
before plain cblas. That runs afoul of the scheme described above. To
|
|
remedy it, we patch the search function so that only "cblas" is
|
|
considered. Since virtual/cblas always pulls in the reference
|
|
implementation, there'd be no point in altering the search order to
|
|
consider e.g. openblas after cblas.
|
|
|
|
Modified 2025/07/30 by Dima Pasechnik <dima@pasechnik,info> to take into account
|
|
a small change in the file to be patched.
