Failing to compile notdeft-xapian using [g++ Ubuntu 7.3.0-27ubuntu1~18.04)]

[clemera]

Hi,

I have not much experience compiling C++ programs. I have installed the deps but compiliation fails (using g++ (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0) with the following output:

Any ideas how to fix it?

[hasu]

It seems that the linker is failing due to missing Xapian symbols. Perhaps that's due to some ABI incompatibility between your compiler and the one that was used to build Xapian. If that's the case, you might try building Xapian from source. Or perhaps different combinations of the library and compiler, if Ubuntu has alternatives available.

After compiling xapian manually it still doesn't work. I don't want to invest more time on this, so I will retry it another time. Thanks!

[anthrolisp]

I'm also having trouble compiling xapian on Ubuntu. The full error message is below. Any help would be greatly appreciated. Many thanks in advance!

It isn't just notdeft-xapian.cc. The ubuntu packaged Xapian examples also don't compile (similar errors, undefined references):

cd /tmp
sudo apt-get install xapian-examples
g++ -std=c++11 -Wall `xapian-config --cxxflags --libs` /usr/share/doc/xapian-examples/examples/simpleindex.cc

I also tested this on a docker image of Ubuntu 19.04 -- same problem. I also tried using different versions of Xapian (actually, these Debian versions: https://packages.debian.org/search?searchon=sourcenames&keywords=xapian-core). No luck. Same problem with 1.4.12-1, and 1.4.11-1. Version 1.2.19-1+deb8u1 was too old.

Looking at the missing symbols, a lot of them actually seem to be there.

nm -C -D /usr/lib/x86_64-linux-gnu/libxapian.so | less

[WarrenWilkinson]

Hallalujah! It works -- you must change the order of arguments in the Makefile. The call to xapian-config must be last. I'll send a pull request soon...

$(PROGRAM) : notdeft-xapian.cc
      g++ -o $@ $< -std=c++11 -Wall `pkg-config --cflags --libs tclap` `xapian-config --cxxflags --libs`

Thank you, Warren, for finding a fix. I've merged your change.
