MORIN --- David, All, Thanks for the report, and the detailed explanations (which I did not yet entirely groked, and will need a bit more time before I see the issue). How many br2-external trees are you using? I've done a bit of testing with 0 to 1000 br2-external trees, and here are the results: $ time make BR2_EXTERNAL='' list-defconfigs real 0m0.129s $ time make BR2_EXTERNAL='(1 item)' list-defconfigs real 0m0.138s $ time make BR2_EXTERNAL='(10 item)' list-defconfigs real 0m0.262s $ time make BR2_EXTERNAL='(100 item)' list-defconfigs real 0m1.912s $ time make BR2_EXTERNAL='(1000 item)' list-defconfigs real 0m19.344s So, what we can see, is that it is roughly linear to the number of br2-external trees. Even the 1000-tree case is far from appearing stuck (granted, it is a bit long, but after seeing 2s for 100 items, it did not feel excruciating to wait). Also, I do not have any message from make 4.2.1 that reports any infinite recursion. Can you provide a bit more details on your configuration? Regards, Yann E. MORIN. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
