make clean; make -j2 check

The commands above create the library twice.
Find out why, and rectify.

Does it happen on all platforms?

History

#1 Updated by Anna Maria Bigatti over 12 years ago

  • Category set to Makefile
  • % Done changed from 0 to 10

#2 Updated by Anna Maria Bigatti about 10 years ago

  • Target version set to CoCoALib-0.99533 Easter14

#3 Updated by John Abbott about 10 years ago

The problem still happens; it's not serious as everything works fine anyway.
I checked on MacOSX 10.5.8.

#4 Updated by John Abbott about 10 years ago

  • Target version changed from CoCoALib-0.99533 Easter14 to CoCoALib-0.99534 Seoul14

#5 Updated by John Abbott almost 10 years ago

  • Target version changed from CoCoALib-0.99534 Seoul14 to CoCoALib-1.0

#6 Updated by John Abbott over 9 years ago

  • Status changed from New to In Progress
  • % Done changed from 10 to 20

Almost certainly part of the problem is that ar ru on Mac OS X updates the mtime of the archive even when the archive does not change -- yet another intelligent Apple design decision... grrrrr!

#7 Updated by John Abbott about 4 years ago

  • Status changed from In Progress to Resolved
  • Assignee set to John Abbott

It still happens -- in a sense.
It is not really harmful; just a bit annoying.

If I do make lib then it compiles the library just once (and prints "Compilation of CoCoALib completed").
If I run make lib a second time, it simply prints out "CoCoALib already compiled".

Aha! If I do make check after having already compiled the library, it prints out CoCoALib already compiled twice. (clue city?)

If I do make cocoa5 after having already compiled the library, it prints out CoCoALib already compiled just once. (good!)

Also make examples prints out "already compiled" just once; so I must have messed up mildly with the test suite.

#8 Updated by John Abbott about 4 years ago

  • Target version changed from CoCoALib-1.0 to CoCoALib-0.99700

#9 Updated by John Abbott about 4 years ago

  • Estimated time changed from 1.55 h to 1.99 h

Here is a bad idea: in the root Makefile I simply removed the dependency of check on library. This does not work because make veryclean; ./configure; make check complains that CoCoA/library.H does not exist.

A possible solution is to declare a dependency of check on dependencies (which in turn triggers the creation of library.H

Alternatively, we can just accept that the message is printed out twice...

#10 Updated by John Abbott about 4 years ago

  • Status changed from Resolved to Closed
  • % Done changed from 80 to 100

I have rearranged the root Makefile: there is a new phony target before-compiling which builds include/CoCoA/library.H and all dependency files. This new target is now a pre-requisite for check (instead of library).
