Yo ho!  I just installed ghc-6.10.4 over my 6.10.3.  Now 'cabal install
lhs2tex' works.  Phew!

Thanks, Don.

Trying your first suggestion, I get the same result for the first and third
method, and a ghc panic on cat_evals for the second method.  All happening
in ghc-6.10.3 installed via the Haskell Platform last week on OS X.

bash-3.2$ cabal install lhs2tex --constraint='base<4'

Now I'll edit add the '< 4' constraint on base, giving the same result:

It's compiling the setup program which is presumably used by cabal to  
do the work a configure script normally does.  "cabal install -- 
verbose=3 lhs2tex" might show what setup is upset about.

or replace Control.Exception with Control.OldException

Personally, I've never used "runhaskell Setup sdist" and I've only

I think cabal-install is a pretty standard util for people to have,
and it ships with the Haskell platform now. So the big hurdle is
documentation.

Andrew - where does it state that "Setup sdist" is the recommended way
of doing this? If it's a wiki you could go and edit it yourself.
  


Start from the Hackage homepage:

 http://hackage.haskell.org/packages/hackage.html

Click on "how to create a Haskell package", takes you to

 http://www.haskell.org/haskellwiki/How_to_write_a_Haskell_program

Section 2.10.1.1 shows you how to create a tarball - using setup sdist 
rather than cabal sdist. Indeed, I don't think cabal-install is 
mentioned anywhere.


If people seriously want this to become the preferred way to do things, 
it needs to be much more prominently documented.

In my opinion you're right, Windows, and things built on it, tend to be very
broken.  Maybe that's why so many of the Haskell devs aren't using Windows?

Well, Duncan informs me that he's just set up a Windows XP VM for this 
exact reason... Still, I guess this problem will only really be solved 
once he have large quantities of Windows users hitting this stuff.


Indeed, Duncan seems to be one of the more helpful inhabitants of the 
Haskell IRC channel. I talked to him tonight, and he's already fixed 
some of the documentation issues I pointed out earlier, and done a 
preliminary analysis of the sdist bug. (It's filed as ticket #565 now, 
by the way.)


Anyway, for the time being, cabal-install does in fact generate the 
tarball, it's just tripping over trying to delete the temp files 
afterwards. So I can still uplo-- wait, you need an account?


Is anything ELSE going to stop me??

Time for bed, I think...

I can't say for certain, but just reading the output it looks like  
it created a tarball in a temporary folder (that worked) and then  
when it tried to clean it up it failed.  Sounds like a bug report  
is in order.


So, yet again, it appears I'm the first poor soul to try using this  
on Windows.


The very first time I tried to use Gtk2hs, the installer for Windows  
was trivially broken. In fairness, Duncan fixed this within an hour  
or two of me pointing out the problem. But the fact remains: It had  
been out for a week, and I was the *only* person to have tried to  
use it on Windows. (Or possibly the only person to actually  
complain, rather than just give up.) Don kept telling me about some  
cool Core syntax hilighter he wrote, so I went to all the trouble of  
downloading it, downloading and building all of its dependencies,  
only to discover "oh, by the way, it only works on Linux". A while  
back Cabal had a bug where (on Windows only) it couldn't find ld or  
something daft. [Again, fortunately that one got corrected -  
eventually - in the next GHC release.] I try to run sdist, and  
discover that that's broken on Windows too. But don't worry, there's  
a replacement tool... which is also broken on Windows... This is an  
exercise in pure frustration! Sometimes it seems as if *everything*  
is broken on Windows.


Hmm... I'm just ranting now. One presumes that when they "fixed"  
cabal sdist to work on Windows, at least one person checked that it  
did, in fact, work. That would mean it got broken again at some  
point after this. Maybe I just need to find an older version or  
something...


And after that... I guess I create *another* account on *another*  
bug tracker and submit *another* "hey, this is broken on Windows"  
ticket...

of me pointing out the problem. But the fact remains: It had been out 
for a week, and I was the *only* person to have tried to use it on 
Windows. (Or possibly the only person to actually complain, rather than 
just give up.) Don kept telling me about some cool Core syntax hilighter 
he wrote, so I went to all the trouble of downloading it, downloading 
and building all of its dependencies, only to discover "oh, by the way, 
it only works on Linux". A while back Cabal had a bug where (on Windows 
only) it couldn't find ld or something daft. [Again, fortunately that 
one got corrected - eventually - in the next GHC release.] I try to run 
sdist, and discover that that's broken on Windows too. But don't worry, 
there's a replacement tool... which is also broken on Windows... This is 
an exercise in pure frustration! Sometimes it seems as if *everything* 
is broken on Windows.


Hmm... I'm just ranting now. One presumes that when they "fixed" cabal 
sdist to work on Windows, at least one person checked that it did, in 
fact, work. That would mean it got broken again at some point after 
this. Maybe I just need to find an older version or something...


And after that... I guess I create *another* account on *another* bug 
tracker and submit *another* "hey, this is broken on Windows" ticket...

You may want to check the "dist" subdirectory of the folder you're
working in to see if it made the tarball.

I can't say for certain, but just reading the output it looks like it
created a tarball in a temporary folder (that worked) and then when it tried
to clean it up it failed.  Sounds like a bug report is in order.

Fortunately, it turns out that a trivial Google search is all that is

Unfortunately I got as far as actually downloading the sources from

Andrew - where does it state that "Setup sdist" is the recommended way
of doing this? If it's a wiki you could go and edit it yourself.
  


The link posted earlier:

http://en.wikibooks.org/wiki/Haskell/Packaging#The_Cabal_file

I'm pretty sure there's some essentially similar content on the Haskell 
wiki. (Or there was... I don't know if it got removed when this was put up.)


The Cabal manual itself mentions absolutely nothing about cabal-install, 
as far as I can tell. (At least, I didn't see anything about it while I 
was looking up the *.cabal format nor the command invocation syntax.)


It's news to me that cabal-install ships with the Haskell Platform. (Can 
you tell how much I've tried out the Platform?) I'm still not completely 
understanding the direction we're going with this - but that's for 
another email...

GHC already ships with Cabal, and half a dozen GNU utilities; would it

I don't know anything that's gauranteed to work, as I've never tried
packaging from a Windows box, but:

 - Is 'htar' a good enough 'tar' replacement for cabal?
 - Does cabal-install also require an external tar? You could try "cabal sdist"

Installation of gtk2hs registers these packages for you.
Again, check `ghc-pkg list gtk`. If you installed gtk2hs, it must be
there. If you, say, upgraded your ghc after you installed gtk2hs, you
have to reinstall gtk2hs.

gtk2hs consists of several cabal packages, e.g. gtk, glib and so on.
(See `ghc-pkg list`)
Specify those of them you need as dependencies in cabal file.

[Haskell-cafe] [cabal] How to deal with build-depency that not under cabal's control?

[Magicloud Magiclouds]

Hi,
  I use gtk2hs in linux. Well, I have no idea how to install gtk2hs by
cabal, but my program needs it, and I want my program cabalized. So
how to do this?
Thanks.

The "Main-Is:" line is wrong: it should be:

>Main-Is:Swish/HaskellRDF/GraphPartitionTest.hs

That is, it should name a filepath (usings slashes), not a module (using
dots).

Re: [Haskell-cafe] Cabal "addressibility" problem

[Ross Mellgren]

If your module statements say Swish in them, e.g.

module Swish.HaskellUtils.TestHelpers where 

then you should probably have no hs-source-dirs (or hs-source-dirs: .)  
and then use Swish.HaskellUtils.TestHelpers.


But leave Main-Is: as you have it.

Right. You understand why it has to be a filepath and not a module
name? Because the module name of an executable would be 'Main', not
HaskellRDF.GraphPartitionTest. You can try compiling something like

module Foo (main) where
main = print "hello world"

and see for yourself how it fails.

Right. hs-source-dirs defined all the module paths as relative to
Swish/; I think the solution here would be to have something like
'hs-source-dirs: ., Swish/'  (or whatever the directory was that the
HaskellUtils stuff can be found in if not ./).

for directory structure I Swish-0.2.1/Swish/HaskellRDF and
Swish-0.2.1/Swish/HaskellUtils  ... there are deeper directories but that
distract from the discussion ... to make things concete:

1) swish.cabal is directly under Swish-0.2.1

2) GraphPartitionTest.hs is under Swish-0.2.1/Swish/HaskellRDF

3) GraphPartitionTest's dependencies are either under HaskellRDF or
HaskellUtils

Hope this helps to make things clearer. I added a "Hs-source-dirs" but that
help.

I did a "ruinhaskell Setup -?" to check on options. I don't see any verbose
mode so that when I do "runhaskell Setup build" I can moniitor the progress
of my build for diagnostic purposes! Is there a verbose mode?

Thanks,

You need to give more detail.

For example, is your directory layout like
'./src/Swish/HaskellRDF.../foo.hs'? In that case, Cabal is looking for
'./Swish/HaskellRDF.../foo.hs'. You need to tell it to look in src/
and not ./ with a line like 'hs-source-dirs: src/' etc.

[Haskell-cafe] Cabal "addressibility" problem

[Vasili I. Galchin]

Hello,

  The following is a fragment in my cabal file:


Executable GraphPartitionTest
   Main-Is:Swish.HaskellRDF.GraphPartitionTest.hs
   Other-modules:  Swish.HaskellRDF.GraphPartition
   Swish.HaskellRDF.GraphClass
   Swish.HaskellUtils.ListHelpers
   Swish.HaskellUtils.TestHelpers



When I try to do a build I get:


Setup: can't find source for Swish in .

Cabal/Setup seem to be looking in the current directory for source but as
you can see I gave "full" paths, i.e. Swish.HaskellRDF* or
Swish.HaskellUtils*.

What I doing wrong?


Regards,

Vasili

The Data.Numbers.Primes module of the primes package does not implement

Oh that'd be great. The Cabal website is managed as a darcs repo so
just:

darcs get http://haskell.org/cabal/

then edit the FAQ.markdown and run make to update the FAQ.html (uses
pandoc). Then darcs send the patches to me or the cabal-devel mailing
list.

The default for "runghc Setup.hs configure" is --global, but the default
for "cabal configure" is --user. So if you're using the "cabal" program
to install packages, then you can also us it to configure other
packages. If for you need to use the runghc Setup.hs interface (e.g. in
some system build scripts) and you want it to pick up packages from the
user package db then use the --user flag. If you're constantly having to
use the runghc Setup.hs interface and doing per-user installs is a pain
then you can set the default for the cabal program to be global installs
in the cabal config file (~/.cabal/config).

I'll add this issue to the FAQ, it come up enough. If anyone else
reading would like to eliminate this FAQ, then implementing this ticket
is the answer:

suggest use of --user if configure fails with missing deps that
are in the user db

The problem is that we're using a parser that has no support for
producing parse errors (Text.ParserCombinators.ReadP). The only reason
we're using this parser is because it's the only one in the core
libraries. Packages like parsec cannot be used in Cabal because Cabal is
a core library and parsec is not.

For this reason we've been considering just copying another parser
module into Cabal so that we can have saner (and quicker) parsing.

For what it's worth, Brian was right, you cannot have a trailing comma
in a list field. Perhaps there was an additional error in the file that
we could not see in the bit you posted.

Idea:

The syntax of the value depends on the field. Field types include:

token , filename , directory

Either a sequence of one or more non-space non-comma characters, or a 
quoted string in 
Haskell 98 lexical syntax. Unless otherwise stated, relative filenames and 
directories are 
interpreted from the package root directory.

Don't use commas.

I've never tried with winhugs and to be honest we don't test much with
hugs either. Don't take that as a discouragement though, it'd be great
to have better support for hugs and winhugs in the cabal tool. All it
needs is someone to pay it a little attention.

For the specific issue, does winhugs come with the hugsffi tool? I
expect that it should do though perhaps it's hidden away in some
directory.

I believe that by default hugs uses $HOME/lib/packages/* for per-user
packages. I'm not quite sure what winhugs does. It'd be good to adjust

[Haskell-cafe] Cabal and WinHugs

[Iavor Diatchki]

Hello,
What is the preferred way to install a cabal package so that it works
with winhugs?  When I tried "cabal install --user --hugs" I got an
error that it could not find "hugsffi".  I managed to get things
working by manually downloading the package, and extracting the
appropriate source directories to the "packages" folder of winhugs
(i.e., basically skipping cabal) but this is kind of clunky. So to
summarize, here are my two questions:
  1. Am I doing something wrong, or does "cabal" not support WinHugs?, and
  2. Does WinHugs have a user specific "packages" folder (so that each
user can have their own set of packages)?
Thanks for any info that anyone might have,
Iavor

[Haskell-cafe] cabal haddock and Paths_Xxx

[Martijn van Steenbergen]

Hello,

cabal generates a Paths_Xxx file for me which I import and use, but 
cabal haddock doesn't seem to like it much.


If I don't specify the generated module at all in my cabal file, cabal 
haddock generates visible documentation for the module, which is not 
what I want: the module should stay internal.


If I specify it in either Exposed-Modules or Other-Modules, 'cabal 
configure; cabal haddock' fails with:



cabal: can't find source for Paths_Xxx in ., dist/build/autogen


While 'cabal configure; cabal build; cabal haddock' fails with:


cabal: can't find source for module Paths_Xxx


Can I have the best of both, i.e. generate docs without problems and use 
the generated module?

[Haskell-cafe] cabal build on mac os 10.5.6 , can't find gmp

[brian]

Hi,

Cabal won't build zlib because it can't find libgmp.

It's there, in /sw/lib (fink installation).

I've modified the bootstrap script and added -L/sw/lib to the ghc  
options.  This is a mystery in itself because ghc is itself a fink  
package and should know where gmp is, so that's already a bad sign.


I can get to the build step with the additional -L option but then ./ 
Setup fails again because it can't find gmp.


Help   ?

Personally, I find a format like:
http://divmod.org/trac/browser/trunk/Nevow/NEWS.txt
simple, compact and flexible.


Nice, simple, and to the point. It reminds me a lot of (a stripped down 
version of) YAML. If we invent a new format, using YAML as the syntax 
would make it easy to manipulate since there are already tools and 
libraries out there for that.



GNU Changelog format is probably an overkill, since nowadays we have 
good revision control systems.


However GNU Changelog format *may* be supported (perhaps the changelog 
format can be specified in a Cabal property).


Like YAML, GNU Changelog has enough history to have a large suite of 
tools for manipulating the format. It's a bit heavy-handed in this day 
and age, but many VCSes can generate it automatically.




As a developer, one of my criteria would be to keep it as lightweight as 
possible (though more formal than raw text). The more work changelogs 
take, the less likely they are to be maintained/accurate.


As a UI issue, I would amend the proposal in ticket #244. Because of the 
way Darcs works around tag boundaries, I've often been lax about tagging 
more frequently than major versions. It'd be nicer to open up the 
pending changelog amendment in $EDITOR so people can adjust it before 
publishing the sdist. (Perhaps with a flag to enable/disable this 
behavior for people who want more automated setups.)


Also helpful would be a command to inject things into the changelog from 
outside the VCS, at times other than when publishing. This is helpful 
for when you realize a version control message omitted details about 
changes, but you can't change the patch, and you don't want to forget 
the details between now and when publishing the new sdist to Hackage. 
Essentially this means the tools should have a pending file for the 
changelog which can be freely modified outside of the system (with some 
in-system tracking so that importing the VCS log and editing it does the 
right thing when trying to import the VCS log again later).


Actually, just having a tool to amend the pending file could be enough. 
Most VCSes have hooks for being able to run things before or after 
committing a patch. Thus, just have a tutorial on setting up the common 
VCSes to commit the same message to the changelog as to the version control.

What it doesn't say is that it's looking for parsec version 2.

> P.S. Note, parsec and network are installed in the system using debian
> distribution packages.

For some reason the debian package maintainers decided to build
everything against parsec 3 rather than parsec 2 which everyone else is
using. Personally I think this was not a wise decision. Indeed it may be
a problem when it comes to supporting the Haskell platform because the
first version will use parsec 2. Any major parsec version transition in
the Haskell platform will be made by a community decision process.

What I've done is dropped the check for parsec in the bootstrap.sh. The
only reason we're looking for parsec is because it's needed by network
which we also need. So it's not strictly necessary that we check for it.

Dear Haskellers and especially who are working on cabal-install
and debian packaging,

I sometimes clean up .ghc and .cabal in my home directory to start from
scratch because of dependency loopholes (cabal-install does not have
remove option yet, so it's hard to fix when such loophole happens).

Today, I had some time in the airport and decided to start from scratch
again because of the dependency loophole with process 1.0.1.1 and
haddock.  I downloaded the most recent version of cabal-install the
version 0.6.2, and found out that the ./bootstrap.sh does not work. So,
I had to bootstrap from version 0.6.2 and do "cabal update" and "cabal
upgrade cabal-install" to upgrade to 0.6.2.

I am not sure whether this is a cabal-install problem or debian
dstribution ghc-6.10.1 packaging probelm, since I have not tried to test
 this with any other ghc-6.10.1 distribution.

If anyone who are not using debian distribution ghc-6.10.1 (e.g.,
general linux binary ghc-6.10.1 or source compiled one) can try
bootstrapping cabal-install 0.6.2 from scratch also finds the same
problem, I think someone should make a ticket for cabal-install.

Thanks,

Ahn, Ki Yung

If it's supposed to work it should work consistently. It's a quirk that
to support old-style .cabal files we allow build-depends but not other
fields in the global section. If we do it properly we should either
allow all fields there, or perhaps in an explicit "common" section or
something.

I hope we can address this and related limitations and quirks in the
Cabal-1.8 development cycle. If you want to help out with that let me
know and I can give you some pointers.

I've wished for this feature, and have Cabal files right now that
would be cleaner with it.  Is there something technically wrong or
undesirable about this feature that necessitates "fixing"?

Thanks.
 From documentation it was not clear this feature.

Thanks, I was going to "fix" my Cabal configuration right now!

However, what happens if hxput add a build-depends field?
Will this override the "global" field?



Manlio Perillo


It doesn't override, but adds to. If the toplevel declares 'base', and then 
hxput does 'build-depends: random', hxput will be built against 'base, random'.

[Haskell-cafe] Cabal and `main-is` field

[Manlio Perillo]

Hi.

I have started to use Cabal for a small project where I have to build 
several executables.


The project layout is something like this:

/
  bin/
a.hs
b.hs
  src/
X.hs
Y.hs


The Cabal configuration file is something like:

executable a
build-depends: haskell98, base, ...

main-is:   a.hs
hs-source-dirs:src bin
other-modules: X

This is perfectly reasonable, but it is odd, IMHO.

I don't understand why `main-is` is relative to `hs-source-dirs`.
What is the rationale?
After all, there is only one executable that can be specified in the 
`executable` block.


The configuration file should be, instead (IMHO, of course):

executable a
build-depends: haskell98, base, ...

main-is:   bin/a.hs
hs-source-dirs:src
other-modules: X


Another "problem" I have noted, is that if I specify `main-is` field two 
times, no error is reported.

Simply, Cabal uses the last directive.



One last thing: is it possible to define "macros" in Cabal?
In my package, I have n executables, that have many dependencies in common.
I would like to avoid having to repeat the same dependencies for each 
executable block.

This is the "diamond dependency problem"

http://blog.well-typed.com/2008/04/the-dreaded-diamond-dependency-problem/

> Can anyone please help me on this?

Most likely you've got two versions of haskell-src installed and some
packages are built against one version and some built against another.
GHC is showing you the fully qualified name here exactly because it
would otherwise refer to a different version.

So here's the thing, cabal-install makes sure that whatever you install
is self-consistent (no conflicting deps). So when you did
$ cabal install haskell-src
and it installed haskell-src-1.0.1.3, it made sure that the deps of that
package were consistent. That *does not* mean that it's dependencies are
consistent with every other package you've got installed. It does not
guarantee global consistency. Only local consistency of the thing you
asked to install.

So what could you do. Well if you were using a .cabal file for your own
program then cabal install on that would also guarantee consistency for
the dependencies of your package. It would try to achieve that from the
current situation by rebuilding packages against different versions of
their dependencies.

If you don't have a .cabal file for your project you can still achieve
the same effect by asking cabal install to install all of the packages
that your project depends on:

cabal install --dry-run haskell-src blah blah blah

That's asking it to find a way of installing all those packages with
consistent deps (which may involve reinstalling some).

The --dry-run will make it show a list of what it would install and some
indication of why. If you use -v too it'll tell you for example if it's
going to rebuild a package against a different version of one of it's
dependencies.

[Haskell-cafe] Cabal haskell-src-1.0.1.3 package bug?

[jpaulo]

[now with the name of the package on subject; appologies for multiple emails]

hello all,

I've used cabal to install package haskell-src-1.0.1.3 under ghc 6.10.1;

Apparently, it worked fine!

However, function parseModule has been given the type:

parseModule ::
  String
  -> ParseResult haskell-src-1.0.1.3:Language.Haskell.Syntax.HsModule

instead of simply

parseModule ::
  String
  -> ParseResult HsModule

as described in the Language.Haskell.Parser module;

This causes conflicting types for all my other modules!


Can anyone please help me on this?

Any help would be very much appreciated!

[Haskell-cafe] cabal install profiling and documentation

i've gone and cabal installed a lot of packages, but now i want to go
back and install their profiling libraries and documentation.  is
there an easy way of doing this, short of reinstalling all of them (in

Thank you all for the very helpful suggestions. I edited ~/.cabal/config 
to generate documentation by default, and I set up Apache to serve the 
documentation from http://haddock. I put a small PHP (gasp!) file in 
~/.cabal/share/doc that lists all packages for which there is 
documentation; see below. This is a good enough approximation for now. 
Thanks again!
