A small archive is enclosed here that shows both remaining strange
effects:
uudecode, unzip --> several files, read readme.txt to install.
1.
Makefile changes to
...
obj:
ghc -odir $(e) -hidir $(e) -package-name docon --make A
docon: obj
rm -f $(e)/libHSdocon.a $(e)/HSdocon.o
ar -qc $(e)/libHSdocon.a $(wildcard $(e)/*.o)
$(RANLIB) $(e)/libHSdocon.a
ld -r -x --whole-archive $(e)/libHSdocon.a -o $(e)/HSdocon.o
And it works this way: make init; make obj; make docon
`obj' looks unnecessary here.
But if we bring the command ghc -odir ... --make A
inside the docon target, then `make docon' does not notice the
appearing file $(e)/A.o and expands $(wildcard $(e)/*.o) to
emptyness. I do not understand, why.
2.
All right, let us, so far, `make' a thing with make init
make obj
make docon
Then, we have $root/A.hs Makefile readme.txt
/d/B.hs
/export/A.o A.hi HSDocon.o libHSDocon.a,
module A exports a = True,
module B imports A and exports b = a,
A.o is in package, B is not.
cd $root
ghci -package docon
...
Loading package docon ... linking ... done.
Prelude> A.a
True -- hence, A is visible
Prelude> :m A
`A' is not currently loaded -- BUG ?
Prelude> :l A
Source file changed or recompilation check turned off
Compiling A ( A.hs, interpreted ) -- BUG ?
...
A>
And in $root/d, it works:
cd $root/d
ghci -package docon
...
Prelude> :l A
module `A' is a package module
Prelude> :m A
A> a
True
A> :l B
... ( B.hs, interpreted )
...
B> b -- B contains b = A.a
True
B>
