I have a package that compiles C++ at runtime using sourceCpp and I would
like to use testthat with the package. Its clear that testthat sets up a
non-standard environment and so it is difficult to combine it with
sourceCpp. The first hurdle was include paths not working.
This bit of code in the test_ file seemed to fix that:
ccflags = Sys.getenv("CCFLAGS")
ipath = file.path(getwd(), "inst", "include")
ccflags = if (nzchar(ccflags)) paste(ccflags, paste0("-I", ipath)) else
paste0("-I", ipath)
Sys.setenv(CCFLAGS = ccflags)
However, once compiled, the object does not load correctly as I cannot call
the compiled function. Does anyone have a workaround? (I have searched and
not found anything terribly useful.)
