[R-pkg-devel] package fails with parallel make - would forcing a serial version work?

(I didn't see an answer to this, so ...)

I think using .NOTPARALLEL will usually get rid of the error but, in my
experience, this problem is usually caused by an incorrect or incomplete
Makefile. When not done in parallel this missing target is usually
getting done first as a side-affect of something that happens before and
usually finishes before it is needed. Your luck does not hold in
parallel. The better fix is to correct your Makefile.

Dear R package developers

I published a package on CRAN last year (sundialr) which is now failing
with as it is not make to compile a static library with parallel make.

In this package, I compile a static library (libsundials_all.a) from

source

files of a third party. The specifics of compiling the static library can
be found at - https://github.com/sn248/sundialr/blob/master/src/Makevars

Now, I got the following error message from CRAN (actually, I was

informed

of this before, but had neglected to fix it). Here is the message from

one

of the CRAN maintainers ..

***************************************************************************************************************************************

This have just failed to install for me with a parallel make:

g++ -std=gnu++98 -std=gnu++98 -shared

cvode.o RcppExports.o -L/data/blackswan/ripley/R/R-patched/lib -lRlapack

-lquadmath -L../inst/ ../inst/libsundials_all.a
g++: error: ../inst/libsundials_all.a: No such file or directory
make[1]: *** [/data/blackswan/ripley/R/R-patched/share/make/shlib.mk:6:
sundialr.so] Error 1

It seems the package fails to generate the static library with the

parallel

make. The easiest solution I could think of for this problem was to

force a

serial version of make using the .NOTPARALLEL phony command in Makevars

and

Makevars.win(https://github.com/sn248/sundialr/blob/master/src/Makevars).

I

have made this change and it seems to work on my machine and on testing
with TravisCI and Appveyor(https://github.com/sn248/sundialr).

However, before I re-submit to CRAN, I wanted to get an opinion as to

will

this be enough to get rid of the error with parallel make?

Any suggestions would be very much appreciated, thank you!
