[R-pkg-devel] Testthat environment using sourceCpp

[Charles Determan]

Greetings,

I am trying to create some unit tests for a Rcpp::sourceCpp call.  It
includes some dependencies with the // [[Rcpp::depends]] flag and compiles
and passes if I call the test file with testthat::test_file.  However, if I
try to call it with devtools::test() to run all of my tests, the
compilation will fail.  I have discovered that this is because of the way
it is trying to find the relevant headers.

The correct call should be:

g++  -std=gnu++11 -I"C:/Users/mydir/DOCUME~1/R/R-34~1.0/include" -DNDEBUG
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/Rcpp/include"
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/BH/include"
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/RcppEigen/include"
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/RViennaCL/include" -
*I"C:/Users/mydir/Documents/R/R-3.4.0/library/gpuR/include"*
-I"C:/Users/mydir/AppData/Local/Temp/Rtmp4MX4Mi"
  -I"d:/Compiler/gcc-4.9.3/local330/include"     -O2 -Wall  -mtune=core2 -c
file32503f79470f.cpp -o file32503f79470f.o



but instead it is looking locally within the package for the 'include'
directory



g++  -std=gnu++11 -I"C:/Users/mydir/DOCUME~1/R/R-34~1.0/include" -DNDEBUG
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/Rcpp/include"
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/BH/include"
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/RcppEigen/include"
-I"C:/Users/mydir/Documents/R/R-3.4.0/library/RViennaCL/include" -
*I"C:/Users/mydir/Documents/R_projects/gpuR/include"*
-I"C:/Users/mydir/AppData/Local/Temp/Rtmp4MX4Mi"
  -I"d:/Compiler/gcc-4.9.3/local330/include"     -O2 -Wall  -mtune=core2 -c
file32503f79470f.cpp -o file32503f79470f.o

This directory is within the 'inst' directory and therefore not found when
an internal header file is referenced.  Any thoughts both why this is
different when call the 'devtools::test()' versus calling the individual
'testthat::test_file()'?

Charles
