Hi Dirk, Rebecca and everybody,
I am struggling to find a method to pass -fsigned-char to
r-cran-bigmemory, which I hope can fix the test failures on arm64.
So far I have tried three approaches:
- A src/Makevars file containing +CXXFLAGS = -fsigned-char
- export DEB_CXXFLAGS_MAINT_APPEND = -fsigned-char in debian/rules
- Pass it directly through --configure-vars, with the following
debian/rules file:
-----------------------------------------------------------
#!/usr/bin/make -f
CXXFLAGS := $(shell dpkg-buildflags --get CXXFLAGS) -fsigned-char
%:
dh $@ --buildsystem R
override_dh_auto_install:
mkdir -p ./debian/r-cran-bigmemory/usr/lib/R/site-library
R CMD INSTALL \
--configure-vars='CXXFLAGS="$(CXXFLAGS)"' \
-l ./debian/r-cran-bigmemory/usr/lib/R/site-library \
--clean . \
--built-timestamp='Wed, 17 Jan 2024 14:04:25 +0100'
-----------------------------------------------------------
In none of these attempts I could see -fsigned-char in the build logs.
I am hitting a wall there as I have little knowledge about the use of
C/C++ in R packages.
Do you know how to pass compiler flags to R CMD INSTALL in the context
of dh $@ --buildsystem R ?
Have a nice day,
Charles
