When building sparsersb with C++17 (and pmr) I see:


octave:1> pkg install -forge -verbose sparsersb
downloading tarball(s) from:
- https://packages.octave.org/download/sparsersb-1.0.9.tar.gz
mkdir (/tmp/oct-HU0kRV)
untar (/tmp/sparsersb-1.0.9-mBoo6t.tar.gz, /tmp/oct-HU0kRV)
checking whether the C++ compiler works... yes
checking for C++ compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether the compiler supports GNU C++... yes
checking whether g++ -std=gnu++17 accepts -g... yes
checking for g++ -std=gnu++17 option to enable C++11 features... none needed
checking for octave... /usr/local/bin/octave-9.1.91

configure: No user-set LIBRSB_TARBALL environment variable detected (set it to
build using a custom librsb tarball).
configure: No librsb tarball provided: following the default procedure.
checking for librsb-config... yes

octave sparsersb package is configured with:
  SPARSERSB_LDFLAGS:     -L/usr/local/lib -lrsb
  SPARSERSB_CXXFLAGS:    -I/usr/local/include/ -D RSBOI_DETECTED_LONG_IDX=1
  SPARSERSB_CXX11:       -std=gnu++11
  OCTAVE:                /usr/local/bin/octave-9.1.91
  MKOCTFILE:             /usr/local/bin/mkoctfile-9.1.91 --verbose -g


Note "SPARSERSB_CXX11:       -std=gnu++11"

That fails later on:
