[Bioc-devel] tokay1 C++14 compiler

Hi Simo,

Glad you were able to switch from install-time to run-time compilation.

The C++14 compiler box for tokay1 shows that this compiler is not
available on this machine. What you see below the box under "Compiler
version" is produced by some code that tries to detect the version
of the compiler despite the compiler not being available. Of course
this fails which is why the output we see doesn't make sense.

I've modified the report generation code so that it doesn't try to
detect or display the version of a compiler that is not available.
The change will take a couple of days before it's reflected on the
report.

Cheers,
H.

Surprisingly, if I design the package such that the stan models are

On the other hand, if I follow the rstan instructions on how to design
an R package that depends on rstan, based on which the stan models are
compiled only once during the build, then I get the previously mentioned
failure only on the windows-based server.

BTW: Recent updates from stan community suggest that the new rstan
version 2.20 will reduce the model compilation time from ~35sec to
~7sec, which makes the decision of sticking with the run-time
compilation setup not so bad.

My understanding - and I could be wrong - is that Stan compiles a
model, so the compiler needs to be available at run time and not just
at build time.

      Thanks!

      I will try to revise the code to avoid CXX14 if this is that case.

      Rstan is built by CRAN through whatever magic / agreement.

      Windows. The options are either to revise your code to avoid CXX14
      or to anticipate that your package will be 'Unsupported on
      Windows' (thereby losing 1/2 your user base).
