# Installation Guide
|
|
|
|
## How to install
|
|
|
|
hledger works on GNU/linux, mac and windows.
|
|
Here are several ways to install it:
|
|
|
|
### a. With your system package manager
|
|
|
|
If you have a system package manager that includes hledger,
|
|
this will be the quickest and easiest way to install,
|
|
if you don't need the very latest version.
|
|
These are listed on [Download](download.html).
|
|
|
|
### b. Download binaries from hledger.org
|
|
|
|
Ready-to-run binaries for GNU/Linux, Mac OSX, and Microsoft Windows
|
|
are provided on a donation basis ([Download](download.html)). These
|
|
are simple compressed executables (not installers), so after
|
|
downloading you may need to decompress, adjust permissions, and rename
|
|
the file. Eg:
|
|
|
|
$ gunzip hledger-web-0.18.2-mac-x86_64.gz
|
|
$ chmod +x hledger-web-0.18.2-mac-x86_64
|
|
$ mv hledger-web-0.18.2-mac-x86_64 /usr/local/bin/hledger-web
|
|
$ /usr/local/bin/hledger-web --version
|
|
|
|
### c. Build released source from Hackage
|
|
|
|
You can download and build the latest release yourself using [cabal](http://www.haskell.org/cabal/users-guide/),
|
|
the standard installer for Haskell software.
|
|
This is the most common way to install hledger, but not always the easiest;
|
|
use the troubleshooting tips below if needed.
|
|
|
|
Ensure you have [GHC](http://haskell.org/ghc) or
|
|
the [Haskell Platform](http://haskell.org/platform) installed.
|
|
Last time we checked, hledger requires GHC 7.2 or greater, and hledger-web requires GHC 7.4 or greater.
|
|
But using the current or previous major GHC version will very likely be easiest.
|
|
|
|
Also note that some Haskell packages depend on C packages, and cabal
|
|
currently isn't able to install or identify those for you. A common
|
|
issue is not having all the ncurses C libraries installed. A quick way
|
|
to ensure you have all required C libs is to
|
|
install hledger [with your system package manager](#a.-with-your-system-package-manager)
|
|
before installing the latest version with cabal.
|
|
|
|
Then install the hledger command-line tool:
|
|
|
|
$ cabal update
|
|
$ cabal install hledger [--dry-run]
|
|
$ hledger --version
|
|
|
|
You should see the proper version reported.
|
|
If you get "could not resolve dependencies", "hledger not found",
|
|
or any other problem, see [troubleshooting](#troubleshooting).
|
|
Also note, to use non-ascii characters like £ in your data, you might need to [configure a suitable locale](MANUAL.html#locale).
|
|
|
|
#### Installing hledger-web
|
|
|
|
To also install the web interface, in theory just do:
|
|
|
|
$ cabal install hledger-web
|
|
|
|
In practice, this is a real beast to keep working, so as of 2014/4/17 it's best to do it this way:
|
|
|
|
$ cabal sandbox init # start with a clean cabal package db, requires cabal 1.18
|
|
$ cabal update
|
|
$ cabal install -j alex happy # update to alex 3.1 and happy 1.19
|
|
$ cabal install -j hledger-web # don't cabal install hledger first
|
|
|
|
This installs hledger and hledger-web. hledger-web will appear as the `web` command in hledger's commands list.
|
|
|
|
There are other [[start#add-on-commands|add-on packages]], hopefully compatible with the current hledger release and your platform.
|
|
|
|
### d. Build latest source from git
|
|
|
|
To download and build the latest development version of hledger, ensure you have
|
|
[git](http://git-scm.com) installed, then:
|
|
|
|
$ git clone http://github.com/simonmichael/hledger.git
|
|
$ cd hledger
|
|
$ cabal update
|
|
$ [optional: cabal sandbox init]
|
|
$ cabal install ./hledger-lib ./hledger [./hledger-web]
|
|
|
|
The same [notes above](#install-from-hackage-with-cabal) about requirements and checking your installation apply. Note this time we mention `cabal sandbox`, a feature of cabal 1.18+ which can be used to reduce package dependency problems; it can be used when installing from Hackage as well.
|
|
|
|
## Troubleshooting
|
|
|
|
There are a lot of ways things can go wrong, especially if you are building from source.
|
|
Here are some known issues and things to try. Please also seek
|
|
[support](DEVELOPMENT.html#support) from the
|
|
[IRC channel](irc://irc.freenode.net/#ledger),
|
|
[mail list](http://hledger.org/list) or
|
|
[bug tracker](http://hledger.org/bugs).
|
|
|
|
Starting from the top, consider whether each of these might apply to
|
|
you. Tip: blindly reinstalling/upgrading everything in sight probably
|
|
won't work, it's better to go in small steps and understand the problem,
|
|
or get help.
|
|
|
|
### hledger not found ?
|
|
If cabal install succeeded but you get a message like "hledger not found" when you run hledger,
|
|
you should add cabal's bin directory to your PATH environment variable.
|
|
Eg on unix-like systems, something like:
|
|
```
|
|
$ echo 'export PATH=$PATH:~/cabal/bin' >> ~/.bash_profile
|
|
$ source ~/.bash_profile
|
|
```
|
|
On Ubuntu 14.04:
|
|
```
|
|
$ echo 'export PATH=~/.cabal/bin:$PATH' >> ~/.bashrc
|
|
$ source ~/.bashrc
|
|
```
|
|
Test your PATH-variable with:
|
|
```
|
|
$ echo $PATH
|
|
```
|
|
### hledger --version shows wrong version ?
|
|
Perhaps you have multiple versions of hledger in your PATH. Eg you installed with the system package manager
|
|
(to get C libs) and then with cabal (to get the latest version), but cabal's bin directory appears too late
|
|
in the PATH. Move it closer to the front.
|
|
|
|
### Did you cabal update ?
|
|
If not, `cabal update` and try again.
|
|
|
|
### Do you have a new enough version of GHC ?
|
|
Run `ghc --version`. hledger requires GHC 7.0 or greater
|
|
(and on [some platforms](#5551), 7.2.1+ can be helpful).
|
|
|
|
### Do you have a new enough version of cabal ?
|
|
Avoid ancient versions, which are less capable and more confusing.
|
|
`cabal --version` should ideally report at least 1.16 (or if you want to
|
|
do sandboxed installs, 1.18). You may be able to upgrade it with:
|
|
```
|
|
$ cabal update
|
|
$ cabal install cabal-install
|
|
```
|
|
|
|
### haskeline fails to install, requires Cabal >=1.16
|
|
|
|
Related to the above. haskeline, one of hledger's dependencies, claims
|
|
to require cabal-install version 1.16+, which is a problem if, say,
|
|
you are on Debian Wheezy and only have cabal-install version 0.14.
|
|
You can relax haskeline's version constraint like so:
|
|
|
|
```
|
|
cabal unpack haskeline
|
|
cd haskeline-X.Y
|
|
(edit haskeline.cabal, comment out the `Cabal-Version: >=1.16` line)
|
|
cabal install
|
|
(resume installing hledger)
|
|
```
|
|
|
|
### Are your installed GHC/cabal packages in good repair ?
|
|
Run `ghc-pkg check`. If it reports problems, some of your packages have
|
|
become inconsistent, and you should fix these first.
|
|
[ghc-pkg-clean](https://gist.github.com/1185421) is an easy way.
|
|
|
|
### cabal says "rejecting: system-fileio-0.3.11, 0.3.10 (conflict: blah blah blah.."
|
|
system-fileio does not yet allow text 1.x, making cabal sweat.
|
|
If your cabal is modern enough, adding `--max-backjumps=10000` should help.
|
|
([more](https://groups.google.com/d/topic/hledger/FdWGTSAVzYU/discussion)).
|
|
|
|
### cabal can't satisfy the new dependencies due to old installed packages
|
|
Cabal dependency failures become more likely as you install more
|
|
packages over time. If `cabal install hledger-web --dry` says it can't
|
|
satisfy dependencies, you have this problem. You can:
|
|
|
|
- (a) try to understand which packages to remove (with `ghc-pkg unregister`)
|
|
or which constraints to add (with `--constraint 'PKG == ...'`) to help cabal
|
|
find a solution
|
|
|
|
- (b) install into a fresh cabal sandbox, created with `cabal sandbox init`.
|
|
([virthualenv](http://hackage.haskell.org/package/virthualenv) or
|
|
[cabal-dev](http://hackage.haskell.org/package/cabal-dev) also work).
|
|
|
|
- or (c<!-- -->) (easiest) erase your installed packages with
|
|
[ghc-pkg-reset](https://gist.github.com/1185421) and try again.
|
|
|
|
For more detail, see [How to cabal install](https://www.fpcomplete.com/user/simonmichael/how-to-cabal-install).
|
|
|
|
### Dependency or compilation error in one of the new packages ?
|
|
If cabal starts downloading and building packages and then terminates
|
|
with an error, look at the output carefully and identify the problem
|
|
package(s). If necessary, add `-v2` or `-v3` for more verbose
|
|
output. You can install the new packages one at a time to troubleshoot,
|
|
but remember cabal is smarter when installing all packages at once.
|
|
|
|
Often the problem is that you need to install a particular C library
|
|
using your platform's package management system. Or the dependencies
|
|
specified on a package may need updating. Or there may be a compilation
|
|
error. If you find an error in a hledger package, check the
|
|
[recent commits](http://github.com/simonmichael/hledger/commits) to
|
|
see if the [latest development version](#installing) might have a fix.
|
|
|
|
### ExitFailure 11
|
|
See
|
|
[http://hackage.haskell.org/trac/hackage/ticket/777](http://hackage.haskell.org/trac/hackage/ticket/777).
|
|
This means that a build process has been killed, usually because it grew
|
|
too large. This is common on memory-limited VPS's and with GHC 7.4.1.
|
|
Look for some memory-hogging processes you can kill, increase your RAM,
|
|
or limit GHC's heap size by doing `cabal install ... --ghc-options='+RTS
|
|
-M400m'` (400 megabytes works well on my 1G VPS, adjust up or down..)
|
|
|
|
### Can't load .so/.DLL for: ncursesw (/usr/lib/libncursesw.so: file too short)
|
|
(or similar): cf [GHC bug #5551](http://hackage.haskell.org/trac/ghc/ticket/5551).
|
|
Upgrade GHC to 7.2.1, or try your luck with [this workaround](http://eclipsefp.github.com/faq.html).
|
|
|
|
### Undefined iconv symbols on OS X
|
|
This kind of error:
|
|
|
|
Linking dist/build/hledger/hledger ...
|
|
Undefined symbols:
|
|
"_iconv_close", referenced from:
|
|
_hs_iconv_close in libHSbase-4.2.0.2.a(iconv.o)
|
|
"_iconv", referenced from:
|
|
_hs_iconv in libHSbase-4.2.0.2.a(iconv.o)
|
|
"_iconv_open", referenced from:
|
|
_hs_iconv_open in libHSbase-4.2.0.2.a(iconv.o)
|
|
|
|
probably means you are on a mac with macports libraries installed, cf
|
|
[http://hackage.haskell.org/trac/ghc/ticket/4068](http://hackage.haskell.org/trac/ghc/ticket/4068).
|
|
To work around temporarily, add this --extra-lib-dirs flag:
|
|
|
|
$ cabal install hledger --extra-lib-dirs=/usr/lib
|
|
|
|
or permanently, add this to ~/.cabal/config:
|
|
|
|
extra-lib-dirs: /usr/lib
|
|
|
|
### "invalid preprocessing directive" on OS X
|
|
|
|
> "I'm trying to cabal install hledger-web on OS X, GHC 7.6, and getting error: invalid preprocessing directive #{mixedAmountAsHtml amt}".
|
|
|
|
[Example](https://gist.github.com/miikka/8886233)
|
|
|
|
Certain OS X and GHC versions do not work well together ([cabal #1496](https://github.com/haskell/cabal/issues/1496), [ghc #7678](https://ghc.haskell.org/trac/ghc/ticket/7678)).
|
|
There's a fix for this in hledger HEAD as of 2014/2/8 (it's not in 0.22.1).
|
|
If you find more cases, please report it.
|
|
|
|
### Many warnings about "missing terminating ' character" on OS X
|
|
|
|
Related to the above problem, can be ignored.
|
|
|
|
### hledger-vty requires curses-related libraries
|
|
On Ubuntu, eg, you'll need the `libncurses5-dev` package. On Windows,
|
|
these are not available (unless perhaps via Cygwin.)
|
|
|
|
### hledger-chart requires GTK-related libraries
|
|
On Ubuntu, eg, install the `libghc6-gtk-dev` package. See also [Gtk2Hs installation notes](http://code.haskell.org/gtk2hs/INSTALL).
|
|
|
|
### error based on missing ncurses C libs on Ubuntu 14.04 trusty
|
|
The following solved my dependency-problem with ncurses (this was required even when I had installed hledger 0.22 via apt-get)
|
|
sudo apt-get install libghc-hscurses-dev libghc-ncurses-dev
|
