It tries to use functions from libdl but doesn't link to it (no -ldl). When setting LDFLAGS="-ldl" it builds just fine, but of course that should only be set for the relevant targets which I haven't tracked down, so no patch from me, I'm sure you can handle that ;)

Comment 1 Stian Skjelstad 2005-06-27 05:17:58 UTC

configure should check for dlopen in -lc and then -ldl

Comment 2 Rouslan Solomakhin 2005-07-08 09:25:00 UTC

Can you atach you "emerge --info", please?

No response from user...

I was looking at this the other day and there seemed to be some check for the  
dl libraries in the configure script of gnupg-1.9.18. 
 
I'm also confused as to why so few people are affected by this.
