I am trying to compile CLN library on an Alpha machine. Now I upgraded the compiler and binutils but I am still getting a lot of undefined symbols (see below). Can anybody help? Was anybody able to compile cln on an Alpha machi- ne?
Yes, me. No problem at all. Actually I was extremely careful testing version 1.1 on any platform I could get my hands on before I released it.
Thanks. Best regards, Ladislav Zejda zejdaz@mbox.vol.cz
Problem: after running "make" I am getting:

Hmm, this setup should work fine. Just one more question (check box): About *how* many undefined symbols did you get? [ ] about 10 [ ] about 100 [ ] about 1000 For me, the link line in your report works just fine. You obviously have some linker confusion. Don't you have a local Linux guru who might help you out with this stuff? You could also try a static library only.
