r-cran-pkgbuild failure in autopkgtest

[Andreas Tille <andreas@an3as.eu>]

Hi,

I tried to upgrade pkgbuild but stumbled upon two errors in the test
suite for the HEAD of Git packaging[1]:


> test_check("pkgbuild")
-- 1. Error: binary builds return correct filenames (@test-build-process.r#33)  
Build process failed
1: expect_true(file.exists(pr$get_built_file())) at testthat/test-build-process.r:33
2: quasi_label(enquo(object), label)
3: eval_bare(get_expr(quo), get_env(quo))
4: file.exists(pr$get_built_file())
5: pr$get_built_file()
6: stop("Build process failed")

-- 2. Error: can build package without src without compiler (@test-build-process
Build process failed
1: without_compiler({
       pr <- pkgbuild_process$new("testDummy", binary = TRUE, dest_path = tmp)
       pr$wait(60000)
       if (pr$is_alive()) {
           pr$kill()
           skip("has not finished in one minute")
       }
       expect_true(file.exists(pr$get_dest_path()))
       expect_true(file.exists(pr$get_built_file()))
       expect_true(!is.na(desc::desc(pr$get_built_file())$get("Built")))

       set_makevars(new, path, makevars_file, assignment = assignment)
       force(code)

== testthat results  ===========================================================
OK: 47 SKIPPED: 2 FAILED: 2
1. Error: binary builds return correct filenames (@test-build-process.r#33) 
2. Error: can build package without src without compiler (@test-build-process.r#41) 

Error: testthat unit tests failed

Does anybody have an idea what "compiler" the test suite is seeking for?

Kind regards

       Andreas.
