如何从源代码构建 libpoppler？

Question

I just download poppler to Linux system,and I want to incorporate it in my app to parse pdf file.
(My goal is to convert pdf file to plain text.)
How can I do this?

Answer 1

Poppler's git tree includes a useless INSTALL doc that just tells you to run ./configure , but they don't include automake/autoconf auto-generated files (including configure) in git. (Probably they do include them in tarball source releases.)

I just built poppler from git source (on Ubuntu 15.04) like so:

git clone --depth 50 --no-single-branch git://git.freedesktop.org/git/poppler/poppler
cmake -G 'Unix Makefiles'  # other -G options are to generate project files for various IDEs
# look at the output.  If it didn't find some libraries,
# install them with your package manager and re-run cmake
make -j4
# optionally:
sudo make install

It appears that they maintain an autoconf/automake build setup, so you can use that OR cmake to create a Makefile .

If you just want to see if the latest git poppler works better than the distro package, you don't need to sudo make install , you can just run utils/pdftotext or whatever right from the source directory. It apparently tells the linker to embed the build path into the binary, as a library search path, so running /usr/local/src/poppler/utils/pdftotext works, and finds /usr/local/src/poppler/libpoppler.so.52 .

If the latest poppler does work better than the distro-packaged poppler, you should install it to /usr/local/bin with sudo make install . When you upgrade to the next version of your distro, check your /usr/local. Often the new distro version will be newer than when you built it from source, so you should just remove your version from /usr/local/{bin,share,lib,man,include} . (Or make uninstall in the source dir, if supported).

Answer 2

Since some time has passed and it seems there was some uncertainty, I also took a look.

At the end of 2021, their homepage says

We run continuous integration via the gitlab CI

I checked out their .gitlab-ci.yml which has many build tasks. It would seem these days we build libpoppler like this:

git clone git://git.freedesktop.org/git/poppler/test test.repo
mkdir -p build && cd build
cmake -DTESTDATADIR=`pwd`/../test.repo -G Ninja ..
ninja

Their website explains it very clearly :

Poppler is available from git. To clone the repository use the following command:

git clone git://git.freedesktop.org/git/poppler/poppler

Once you download the source code, read the INSTALL file where it says :

1. cd to the directory containing the package's source code and type ./configure to configure the package for your system.

2. Type `make' to compile the package.

3. Type `make install' to install the programs and any data files and documentation.
