Bug 179639 – app-portage/portage-utils-0.1.27 fails to link w/ user supplied LDFLAGS

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Doug Goldstein (RETIRED) 2007-05-24 14:09:12 UTC]

q.c and main.c use dl* functions without including dlfcn.h, as such it fails to compile.

wow. I totally did not read that error message at all. It's a linking issue since you're specifying the -ldl too early. Just tack the -ldl onto the end and it will be ok.
