Andreas,
This looks like an error: > reassign 1037439 src:r-base Bug #1037439 {Done: Dirk Eddelbuettel <e...@debian.org>} [r-cran-rstan] r-cran-rstan/armhf FTBFS with r-cran-bh 1.74, works with boost 1.81 Bug reassigned from package 'r-cran-rstan' to 'src:r-base'. No longer marked as found in versions r-cran-rstan/2.21.8-1 and r-cran-bh. r-base-core cannot possibly be the cause. What we have here is that - R packages can use (C++ upstream library) Boost (from boost.org) - (ie not be confused with a CRAN package called boost) - I happen to be upstream for CRAN package BH - Which I update annually in December, so CRAN is now at 1.81 - Because BH is big we once decided to _not_ double it up in Debian - So we have r-cran-bh essentially as a virtual package depending on libboost-all-dev In June, we put a hard version constraint into r-cran-bh to enfore 1.81 or later: r-cran-bh (1.81.0-1) unstable; urgency=medium * debian/control: Update Build-Depends to libboost1.81-dev to ensure use of Boost 1.81 (needed eg by rstan) which is not yet the default Boost in Debian, but available. Note to re-set this to libboost-dev once it is default. Thanks to Steve Langasek for the idea. (Closes: #1037439) * debian/control: Set Build-Depends: to current R version * debian/control: Set Standards-Version: to current version * debian/control: Switch to virtual debhelper-compat (= 12) -- Dirk Eddelbuettel <e...@debian.org> Tue, 13 Jun 2023 07:10:09 -0500 Steve may have suggsted that at the time for Ubuntu build issues. So is this now in Debian unstable/testing? IIRC there was a migration. Thanks for any pointer, Dirk -- dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org
