15.2.3 Parallel Test Harness You can set the TEST_LOGS variable. By default, this variable is computed at make run time from the value of TESTS as described above. For example, you can use the following:
set x subset*.log; shift env TEST_LOGS="foo.log $*" make -e check What does setting TEST_LOGS do? It is read only in the Makefile file. There is an unclear explanation of the TEST_LOGS meaning (don't explain, I think I've got it figured out). And it sort of makes sense. TEST_LOGS contains the name of all .log files. I get that. What happens if the user changes one or all the names. Suppose Makefile looks something like: TESTS = foo.exe Then TEST_LOGS = foo.log And the user sets this to env TEST_LOGS = bar.log make -e check What on earth does this mean? And the examples with TEST_EXTENSIONS and duplicate base names (test cases with extensions removed, like TESTS = test.sh test.pl and TEST_EXTENSIONS = .pl .sh) grows even more complex. Any idea? And what does 'set x subset*.log; shift' have to do with anything. It looks like something erroneously removed from an existing script and put in the document.
