It still looks like notdeft-xapian.cc is compiling, and there is also no complaint about TCLAP, but for some reason linking against libxapian fails. You might be better off asking some Ubuntu chatroom for suggestions, as so far only Ubuntu users are reporting this problem.

But there are things to try to find out more.

Most importantly, check the output of xapian-config --cxxflags --libs and confirm that the .so file is actually present.

If so, try compiling with different options, and in smaller steps. For example: g++ -c -Wall pkg-config --cflags tclap xapian-config --cxxflags .cc g++ pkg-config --libs tclap xapian-config --libs .o

Or more verbosely g++ -v -Wl,-v pkg-config --libs tclap xapian-config --libs *.o

If you can't find a way to link against Ubuntu's Xapian binaries, the good news is that Xapian doesn't have many dependencies, so it's probably not too difficult to build it yourself, so that you then know what you have, and that it's ABI compatible. Just remember then to tell g++ to link notdeft-xapian.o against your build of the library.

Thanks for getting back to me!

Here are the outputs.

Most importantly, check the output of xapian-config --cxxflags --libs and confirm that the .so file is actually present.

-L/usr/lib/x86_64-linux-gnu -lxapian

notdeft-xapian.o is present

g++ -c -Wall pkg-config --cflags tclap xapian-config --cxxflags *.cc

no output. looks like it compiles successfully

g++ pkg-config --libs tclap xapian-config --libs *.o

[anthrolisp]

It SEEMS to be working now, even with the error, using notdeft-example.el . Could notdeft not be using xapian and deft's search engine instead?

[hasu]

Those linker errors look pretty severe. However, NotDeft mode supports basic filtering even without the notdeft-xapian program.

It appears that the following command records more information about the libraries that are successfully loaded by the linker, and the Xapian symbols that are found g++ -Wl,-Map=output.map -Wall pkg-config --cflags --libs tclap xapian-config --cxxflags --libs *.cc && grep -i xapian output.map

[hasu]

In your case it doesn't get that far. How about cat output.map

Do you even have the Xapian library binary? ls -l /usr/lib/x86_64-linux-gnu/libxapian.so

[anthrolisp]

I appreciate your help with this. I wish I knew more!

cat output.map

The output is too many characters to post here or Pastebin! What should I be looking for?

cat output.map attached. catoutput.txt

I uninstalled through the official package manager. Installed xapian by source, without error. Then, retried making notdeft-xapian, same errors.

I might just switch to a non Ubuntu based distro.

[hasu]

Looking at the ld output it seems that the linker does load libxapian.so, and finds many Xapian symbols from there, but not nearly all, hence the numerous errors. That suggests that it could indeed be an ABI mismatch, as suspected.

You're using GCC 8.2 as your C++ compiler, which is quite new, bleeding edge, even. Is that the default on Ubuntu 18.04? I would try with GCC 6 or 7, if those are available for installation on Ubuntu 18.04. Perhaps they are a better match for Ubuntu's libxapian.so.

[anthrolisp]

Before receiving your latest message, I uninstalled GCC 8.2 through the package manager, and tried installing it from source. Unfortunately, I was successful because now I cannot uninstall it. There's no make uninstall. I did install GCC 6, and tried to setting it as as the default through update-alternatives. When I compile now, it starts with a different set of errors, then follows with what appears to be the same. It seems to be reverting back to GCC 8. I'll come back to this on 3/11, and fix it one way or another! I'm determined to install notdeft! :-)

What OS do you use?

[anthrolisp]

Some progress: Currently testing on Manjaro.

• make in the Xapian directory returns without error. Creates notdeft-xapian file.
• I then configured the Xapian backend pointing to that file.
• when i call notdeft now from inside emacs, i can get an EMPTY nodeft buffer with the follow error: file-name-nondirectory: Wrong type argument: stringp, nil
• when i hit tab, and "Query:" comes up, but no return of any files, not another error as above.
• when i comment out the line pointing to the Xapian backend, and call notdeft, the buffer comes up listing my files with the usual filtering.
• Thoughts? Many thanks in advance!

[anthrolisp]

I changed the xapian backend directory from "~/xapian/notdeft-xapian" to the full path "/home/NAME/xapian/notdeft-xapian" and it seems to be working!! Will try it on a full install now.

[anthrolisp]

Working! Thank you for all of your help!

[hasu]

You're right, the notdeft-xapian-program path cannot use the "~/" shorthand, since that path is not subjected to expansion by the shell. I'll amend the docs to say that more clearly. Thank you for pointing that out.

A resolution to the build problems on Ubuntu 18.04 shall continue to be unknown.

[anthrolisp]

Is this issue solved here now?

[hasu]

Let's assume so.
