# INSTALL
To build this code after doing a Git clone, run:
$ ./acprep dependencies
$ ./acprep update
If anything goes wrong, see [COMMON CONFIGURE/BUILD PROBLEMS](#common-configure--build-problems)
If you try to configure and build without running acprep first, you are
almost certainly going to run into problems. In future, you can run
`acprep update` again and again, and it will keep you updated to the
very latest version.
Now install it:
$ sudo make install
## COMMON CONFIGURE / BUILD PROBLEMS
To build and install Ledger requires several dependencies on various
platforms. You can install these dependencies very simply for most of them
using:
$ ./acprep dependencies
The first order of business if acprep update doesn't work is to find out where
things went wrong. So follow these steps to produce a bug report I can track
down easily:
$ ./acprep --debug update # shows what acprep was thinking
$ $EDITOR CMakeCache.txt # shows what cmake was thinking
With the contents of config.log, and the output from acprep --debug update,
it's usually fairly obvious where things have gone astray.
## F.A.Q.
Q: The build fails saying it can't find `utf8.h`
A: You didn't run `./acprep update`.
----------------------------------------------------------------------
Q: `./acprep update` gives errors or `./acprep dependencies` fails
A: You're probably missing some dependency libraries. If you tried
`./acprep dependencies` already and that didn't solve the problem,
then you may need to install dependencies by hand. On a Debian
GNU/Linux system (or Debian-based system such as Ubuntu), something
like this should work (as root):
$ sudo apt-get install build-essential cmake texinfo python-dev \
zlib1g-dev libbz2-dev libgmp3-dev gettext libmpfr-dev \
libboost-date-time-dev libboost-filesystem-dev \
libboost-graph-dev libboost-iostreams-dev \
libboost-python-dev libboost-regex-dev libboost-test-dev \
doxygen libedit-dev libmpc-dev tzdata
----------------------------------------------------------------------
Q: Configure fails saying it can't find boost_regex
A: Look in config.log and search for "boost_regex", then scroll down a bit
until you see the exact compile error. Usually it's failing because
your include directory is different from anything acprep is expecting to
see. It could also be failing because your Boost libraries have a
custom "suffix" on them.
Let's say your Boost was installed in ~/boost, and every library has the
suffix `-xgcc42`. This is what you would run:
$ CPPFLAGS=-I$HOME/boost acprep --boost=xgcc42 update
----------------------------------------------------------------------
Q: Configure fails saying it can't find MPFR
A: You need MPFR version 2.4.0 or higher. This version does not come with
most Debian distributions, so you will need to build it. The
relevant packages are `libmpfr-dev` and `libmpfr-dbg`. See also
the question above about what to do if `./acprep update` gives
errors or `./acprep dependencies` fails.
----------------------------------------------------------------------
Q: I'm seeing a segfault deep inside the boost_regex code!
A: Actually, the real segfault is in libstdc++'s facet code. It's being
caused by using a debug Boost with a non-debug build of Ledger, or
vice-versa.
----------------------------------------------------------------------
Q: Something else fails, or Ledger crashes on startup
A: This, I am most interested in hearing about. Please
[file a bug report](https://bugs.ledger-cli.org/new) at the
[Ledger Issue Tracker](https://bugs.ledger-cli.org). The more
details you can provide, the better. Also, if Ledger is crashing, try
running it under a debugger, e.g. gdb or lldb, like so:
$ gdb ledger
(gdb) run <ARGS TO LEDGER>
... runs till crash ...
(gdb) bt
Put that backtrace output, and the output from `ledger --version`
in the bug report.
----------------------------------------------------------------------
Q: Whenever I try to use the Python support, I get a segfault
A: Make sure that the boost_python library you linked against is using the
exact same Python as the Ledger executable. In particular I see this
bug on macOS systems where boost_python is linked against the default
Python, while Ledger is linked against the version provided by MacPorts.
Or vice versa.
Solution: Use one or the other. If you prefer the system Python, run
`port deactivate -f python26`, to get MacPorts' version out of the way.
You'll then need to delete the Ledger binary and run `make` to relink
it.
----------------------------------------------------------------------
Q: When I run `make check`, the Python unit tests always crash
A: This can happen for the same reason as above. It can also happen if you
have ICU support enabled. This is a bug I'm still trying to track down.
----------------------------------------------------------------------
Q: My distribution has versions of Boost and/or CMake that are too old for
Ledger. How do I build my own Boost and/or CMake binaries that will
work properly with Ledger? Thereafter, how do I configure Ledger
properly to use those newly built versions of Boost and/or CMake?
A: Here's commands that one user used to make this work, for Boost 1.72.0
on Debian GNU/Linux 11 (aka Debian bullseye). It's likely to work ok
for other versions of Boost as well. [YMMV] on other distributions and/or
other Debian versions, though.
- Preparing and building Boost
$ export BOOST_VERSION=1.72.0
$ cd /somewhere/you/want/to/build/boost
$ wget -N https://boostorg.jfrog.io/artifactory/main/release/$BOOST_VERSION/source/boost_${BOOST_VERSION//./_}.tar.gz
$ tar xvf boost_${BOOST_VERSION//./_}.tar.bz2
$ cd boost_${BOOST_VERSION//./_}
$ ./bootstrap.sh
$ ./b2 --build-type=complete --layout=tagged --prefix=/where/you/want/boost/installed
$ ./b2 --build-type=complete --layout=tagged --prefix=/where/you/want/boost/installed install
- Preparing and building CMake
$ export CMAKE_VERSION=3.16.2
$ cd /somewhere/you/want/to/build/cmake
$ wget -N https://cmake.org/files/v${CMAKE_VERSION:0:-2}/cmake-${CMAKE_VERSION}.tar.gz
$ tar xvf cmake-${CMAKE_VERSION}.tar.gz
$ cd cmake-${CMAKE_VERSION}
$ ./configure --prefix=/where/you/want/cmake/installed/
$ make
$ make install
- Building Ledger using the CMake and/or Boost as installed above
$ cd /path/to/ledger/sources
$ env PATH=/where/you/want/cmake/installed/bin:$PATH BOOST_ROOT=/where/you/want/boost/installed PREFIX=/where/you/want/ledger/installed $SHELL
$ ./acprep --prefix=$PREFIX --debug --python config
$ ./acprep --prefix=$PREFIX --debug --python make
$ ./acprep --prefix=$PREFIX --debug --python install
