Re: [Xen-users] Autoconf fail to check libncurses

[fpostic@xxxxxxxxxxxxxx]

UPDATE SOLVED : 
I have found the source of the ./configure script failing and it seems that it 
is not related to -libncurses but to python2.7. 
I found these lines in config.log for tools :

configure:7733: checking for clear in -lncurses
configure:7758: cc -o conftest -g -O2       conftest.c -lncurses  -lpython2.7  >
&5
/usr/bin/ld: cannot find -lpython2.7
cc: error: linker command failed with exit code 1 (use -v to see invocation) 

I ran :
ld -lpython2.7 --verbose and found out that libpython2.7.so located in 
/usr/local/lib was not found by ld. Linked the lib in /usr/lib solved the 
problem.

Hope my troubles can save time for next people searching this error in a search 
engine.
