So I've run into a (legitimate) issue with building 6.8.3.

Initiall I was getting things like this:


build error:
../compiler/ghc-inplace -optc-O -optc-Wall -optc-W -optc-Wstrict-prototypes
-optc-Wmissing-prototypes -optc-Wmissing-declarations -optc-Winline

debug_o -optc-DDEBUG   -c ProfHeap.c -o ProfHeap.debug_o

Printer.c:962:17:  error: bfd.h: No such file or directory


this was being caused by not being able to find binutils-related 
headers.  similar errors occured after not being able to find readline 
headers.  (these were in a non-standard location).

I got around this by exporting some env vars:

export CPPFLAGS="-I/lusr/gnu/include -I/lusr/include"
export LDFLAGS="-L/lusr/lib -L/lusr/gnu/lib"

however, that still didn't solve the problem, and eventually I resorted 
to "grafting" (copying via symlinks) the include files into the 
build-dir/includes directory.

that worked until I ran into this:

specifically, what is failing is the "setup/Setup makefile -f 
GNUmakefile" command.


bash-3.2$ setup/Setup makefile -f GNUmakefile

however, if you cd into build-dir/libraries/readline and run this manually:


./configure --with-readline-includes=/lusr/gnu/include
--with-readline-libraries=/lusr/gnu/lib


you can then run the "setup/Setup makefile -f GNUmakefile" and it works.


so I thought I'd try simply modifying the libraries/Makefile:


bash-3.2$ diff -urN libraries/Makefile.orig libraries/Makefile

but that doesn't work:

At this point I think this has gotten a little too hack-ish, so I 
thought I'd ask the mailing list what for proper way of telling ghc 
where your readline installation lives?
