libxapian-dev on Debian Jessie doesn't seem to satisfy (optional) dependency

[orblivion]

I notice that when I build, even having installed libxapian-dev via Debian Jesse, it says that the xapian-core dependency was not satisfied. It built anyway since it's an optional dependency, so perhaps the person writing the README did not notice. Or, maybe Debian Jesse has too old a version of libxapian-dev, such that it doesn't have the pkg-config thing.

Something like $ pkg-config --modversion xapian-core will tell you whether pkg-config sees the library as installed. I can test on Debian Jessie tomorrow probably.

I found a separate debian jesse system, installed libxapian-dev, and ran:

$ pkg-config --modversion xapian-core
Package xapian-core was not found in the pkg-config search path.
Perhaps you should add the directory containing `xapian-core.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xapian-core' found

[orblivion]

I may try to build libxapian, seeing as I'm building libzim and libpugiximl anyway. If I can show it to work, perhaps you could add it as a "if you have Debian jesse" section.

What is the xapian version on Debian Jesse ? Xapian 1.4.0 install a xapian-core.pc by default.

Can you run pkg-config --list-all to get the list of all modules ? Maybe the pkg-config xapian file has changed and we have to use another name than xapian-core.

In Debian unstable (sid/stretch):

root@DebianSid4:~# apt-file list libxapian-dev | grep pc
libxapian-dev: /usr/lib/x86_64-linux-gnu/pkgconfig/xapian-core.pc
root@DebianSid4:~# dpkg -l | grep xapian
ii  libxapian-dev                 1.4.2-1                     amd64        Development files for Xapian search engine library
ii  libxapian30:amd64             1.4.2-1                     amd64        Search engine library
root@DebianSid4:~# pkg-config --modversion xapian-core
1.4.2

More digging and it appears 1.2.21 is the minimum version with a pkg-config file:

xapian-core (1.2.21-1) unstable; urgency=medium

  * New upstream release:
    + Now provides pkg-config file, packaged in libxapian-dev.
  * debian/rules: It's safe to assume dpkg >= 1.16.1 now, so simplify
    use of dpkg-buildflags.
  * Upstream releases are now bootstrapped with a newer libtool, so
    dh_autoreconf is no longer needed.

I strongly recommend to require Xapian >= 1.4.2

[kelson42]

Here there is nothing we can do. We need Xapian 1.4.2 with pc file.

For the record, I went ahead with building xapian-core (1.4.3) myself rather than using Debian Jesse's version and it's worked out.
