MORIN --- David, All, Here's how I prepared the test br2-external trees: $ for i in $(seq 1 1000); do mkdir -p br2-external-${i}/configs touch br2-external-${i}/{Config.in,external.mk} echo "name: BR_TEST_${i}" >br2-external-${i}/external.desc touch br2-external-${i}/configs/foo{,_${i}}_defconfig done So, I get minimal br2-external trees, each with two defconfigs: one that is present in all br2external trees, and one that is specific to each tree. And here is exactly how I tested that: $ make --version GNU Make 4.2.1 $ for ext in 1 10 100 1000; do time make BR2_EXTERNAL="$(for i in $(seq 1 ${ext}); do echo $(pwd)/br2-external-${i}; done)" list-defconfigs >/dev/null; done 2>&1 |grep real real 0m0.179s real 0m0.245s real 0m1.299s real 0m18.277s What version of make are you using? How many br2-external trees do you have? However, please do note that indeed, it was never envisioned that more than a few br2-external trees be used simultaneously. But that it feels like it got stuck is still not a nice behaviour... Regards, Yann E.
