A little ltrace reveals that euses checks PORTDIR and continues with "(null)" as value for PORTDIR. Looking at the source, the result from getenv is unconditionally passed to snprintf, and later on only its lengh is checked to be nonzero. So a nonexistant environment variable becoms a NULL pointer returned from getenv becomes the string "(null)" becomes euses idea of a valid PORTDIR. Martin.vGagern@gmx.net 2006-11-24 10:48:35 0000 Created an attachment (id=102671) euses-2.5.2-getportdir.patch This at least lets getportdir check if the environment variable is set. If so, use it, if not, check make.globales and make.conf. jer@gentoo.org 2006-11-24 14:19:29 0000 Sorry, I thought I had already fixed that. Seems I didn't publish the fixed version yet. 2.5.3 is in the tree with a fix similar to your patch. Thank you very much for the bug report. jer@gentoo.org 2006-11-24 14:20:01 0000 Forgot an option. 102671 2006-11-24 10:48 0000 euses-2.5.2-getportdir.patch euses-2.5.2-getportdir.patch text/plain LS0tIGV1c2VzLTIuNS4yL2V1c2VzLmMJMjAwNi0xMS0yNCAxOToxODowNy4wMDAwMDAwMDAgKzAx MDAKKysrIHdvcmsvZXVzZXMuYwkyMDA2LTExLTI0IDE5OjIxOjI4LjAwMDAwMDAwMCArMDEwMApA QCAtMTI4LDEwICsxMjgsMTMgQEAKIAlGSUxFICpmZDsKIAogCS8qIENoZWNrIGlmIFBPUlRESVIg aXMgc2V0IGluIHRoZSBlbnZpcm9ubWVudCAqLwotCXNucHJpbnRmKHBvcnRkaXIsIEZJTEVOQU1F X01BWCwgIiVzIiwgZ2V0ZW52KCJQT1JURElSIikpOworCWNoYXIgKmVudnBvcnRkaXIgPSBnZXRl bnYoIlBPUlRESVIiKTsKKwlpZiAoZW52cG9ydGRpciAhPSBOVUxMKSB7CisJCXNucHJpbnRmKHBv cnRkaXIsIEZJTEVOQU1FX01BWCwgIiVzIiwgZW52cG9ydGRpcik7CisJfQogCiAJLyogb3IgbG9h ZCBpdCBmcm9tIG1ha2Uue2dsb2JhbHMsY29uZn0gKi8KLQlpZiAoc3RybGVuKHBvcnRkaXIpID09 IDApIHsKKwllbHNlIHsKIAkJLyogT3BlbiBhIHBpcGUgdG8gc2ggKi8KIAkJZmQgPSBwb3Blbigi c291cmNlICIgU1lTQ09ORkRJUiAiL21ha2UuZ2xvYmFsczsiICJzb3VyY2UgIgogCQkJICAgU1lT Q09ORkRJUiAiL21ha2UuY29uZiIgIjsiICJlY2hvIC1uICR7UE9SVERJUn0iLAo=
