Re: [Ltib] Ubuntu 11.10 install issues (was Re: LTIB build error: lkc package build errors with unresolved symbols)

[Andrew Craig]

I am getting the same errors here in 11.10 as well.  After a bit of 
looking around perhaps this explains the cause?

Quote:
"just for future reference as this is a common problem:

oneiric uses the linker flag --as-needed by default. With this flag 
correct ordering of libraries and objects on the commandline is important.
objects needing symbols must be placed before libraries providing them.
E.g. file.o and staticlib.a need symbols from libm:
wrong:
gcc -lm file.o staticlib.a
gcc will think libm is not needed and drops it, when it later encounters 
the objects needing it you will get undefined references
right:
gcc file.o staticlib.a -lm

Important for autotools makefiles. Place libraries into LIBS or LDADD 
variables, not in LDFLAGS"

So moving where -lncurses is in the command might fix the problem?
