src/Makevars ignored ?
Hello,
I'm tring to install a Rpackage that holds some C//C++ code
as far as I understood the R library generic compilation mechanism,
compilation of C//C++ sources is controled
1) at system level by the ocntentos RHOME/etc/Makeconf
2) at user level by the content of ~/.R/Makevars
3) at package level by the content of src/Makevars
Problem I have is that src/Makevars is ignored

You have not demonstrated that src/Makevars is ignored -- as it clearly
isn't, given how thousands of CRAN packages use it.
What you have done is demonstrate that you _cannot change CC and CXX_ in
src/Makevars. And I think that was known, though maybe not as widely.

Hello Dirk,
so why ~/R/Makevars allows to change CC and not src/Makevars ?
this is pretty confusing.

Any change of rsync using threads instead of fork?
On a typical embedded Linux device, with no MMU, there is no fork() or
it returns ENOSYS.
The nearest replacements are vfork() (which is only useful before
exec*()), or to create threads with pthread_create().
rsync would be a very useful program on such devices, and I was a bit
disappointed to build it, only to find the compile went fine but it
failed at runtime due to ENOSYS.
Is there any
