[R-package] CRAN requires a new release by Feb 14th #6791
Description
Description
On January 14th, I received the following email from Dr. Brian Ripley (speaking on behalf of CRAN):
GCC 15 has now reached 'stage 4', which typically means it is about a
month from release, so please submit an update before 2025-02-14.
lightgbm is also causing UBSAN issues in package gpboost and has
installation issues on Alpine Linux.
To stay on CRAN, we must put up a new release (at least of the R package) by February 14th.
Notes
Problem 1: "installation issues on Alpine Linux"
details: https://cran.r-project.org/web/checks/check_results_lightgbm.html
Version: 4.5.0
Check: top-level files
Result: NOTE
possible bashism in configure.ac line 63 (should be VAR="${VAR}foo"):
LGB_CPPFLAGS+=" -DMM_PREFETCH=1"
possible bashism in configure.ac line 89 (should be VAR="${VAR}foo"):
LGB_CPPFLAGS+=" -DMM_MALLOC=1"
fixed by: #6746
Problem 2: "GCC 15 has now reached 'stage 4'"
details: https://www.stats.ox.ac.uk/pub/bdr/gcc15/lightgbm.out)
io/json11.cpp:102:28: note: 'uint8_t' is defined in header '<cstdint>'; this is probably fixable by adding '#include <cstdint>'
io/json11.cpp:103:28: error: 'uint8_t' does not name a type
103 | static_cast<uint8_t>(value[i + 1]) == 0x80 &&
| ^~~~~~~
fixed by: #6736
Problem 3: "lightgbm is also causing UBSAN issues in package gpboost"
Not sure what this refers to. I don't see any issues at these places:
- https://cran.r-project.org/web/checks/check_results_gpboost.html
- https://github.com/search?q=repo%3Afabsig%2FGPBoost%20UBSAN&type=code
@fabsig what does this note from CRAN refer to?
