[Haskell-cafe] trouble installing ghc 6.6: xargs: /usr/bin/ar: terminated by signal 11

[Daniil Elovkov]

Hello

cmm.h seems to sit in TOPDIR/includes

In the makefile these lines are close

SplitObjs=NO

H_FILES = $(wildcard ../includes/*.h) $(wildcard *.h)

Maybe you accidentally did something with the second while editing the first.
