The install used to work for me on Ubuntu 20.04, but on Ubuntu 24.04 I get this error when trying to compile the xapian-lite module required by xeft:

(module-open-failed "/home/fap/.emacs.d/elpa/xeft-3.3/xapian-lite.so" "/snap/emacs/2504/usr/bin/../../lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by /home/fap/.emacs.d/elpa/xeft-3.3/xapian-lite.so)")

I tried to use the workaround from #71 like this:

(let* ((emacs-snap-dir (file-name-as-directory (getenv "EMACS_SNAP_DIR")))
       (process-environment (append `(,(concat "CC=" emacs-snap-dir "usr/bin/gcc-10" )
                                      ,(concat "CXX=" emacs-snap-dir "usr/bin/g++-10")
                                      ,(concat "CFLAGS=--sysroot=" emacs-snap-dir " -B" emacs-snap-dir "usr/lib/gcc")
                                      ,(concat "CPATH=" (file-name-directory (car (file-expand-wildcards (concat emacs-snap-dir "usr/include/*/bits")))))
				      ,(concat "CPPFLAGS=--sysroot=" emacs-snap-dir)
				      ,(concat "LDFLAGS=--sysroot=" emacs-snap-dir " -L" emacs-snap-dir "usr/lib" " -L" "/lib/x86_64-linux-gnu/")
                                      ,(concat "PKG_CONFIG_PATH=" (car (file-expand-wildcards (concat emacs-snap-dir "usr/lib/*/pkgconfig")))))
                                    process-environment)))
    (xeft))

Note that I added " -L" "/lib/x86_64-linux-gnu/" so the build finds the libxapian that I installed via sudo apt install libxapian-dev:

$ ldconfig -p | rg xapian
	libxapian.so.30 (libc6,x86-64) => /lib/x86_64-linux-gnu/libxapian.so.30
	libxapian.so (libc6,x86-64) => /lib/x86_64-linux-gnu/libxapian.so

But then I guess libxapian doesn't like the environment from the snap:

Does anyone know how to fix this?

So to have this work you would need to compile it against the version of libxapian-dev from the Ubuntu 20.04 LTS release (as this is what the rest of the emacs snap is using). As a workaround, I could add this package to the emacs snap itself and then you should be able to do the same kind of workaround as was done for compiling jinx.

Ok with any luck the change I just added will get automatically built and published to the beta channel in the next few hours - if you are able to test this with the workaround - BUT WITHOUT your change to add " -L" "/lib/x86_64-linux-gnu/" (since we want libxapian to come from the snap, not from the host) - then let me know, that would be great. Thanks.

Looking at the upstream repo for xeft, to compile the module it calls make but the Makefile hardcodes the CXXFLAGS and LDFLAGS - so I don't think you can easily workaround it to get it to compile using the libxapian shipped in the snap - whilst you could specify PREFIX as (concat (file-name-as-directory (getenv "EMACS_SNAP_DIR")) "usr/lib"), I think you would still need to override CXXFLAGS and LDFLAGS to be able to specify --sysroot etc.

So even with this fix in place in the snap, I think it would be worth sending a PR to upstream xeft to make CXXFLAGS / LDFLAGS etc customisable (ie: declare them with the ?= operator rather than just =).

So at the moment, you would at least need to use something more like the following to get it to try to get it to compile but I suspect you would also need to override CXXFLAGS and LDFLAGS as well:

(let* ((emacs-snap-dir (file-name-as-directory (getenv "EMACS_SNAP_DIR")))
       (process-environment (append `(,(concat "CXX=" emacs-snap-dir "usr/bin/g++-10")
                                      ,(concat "PREFIX=" emacs-snap-dir "usr/lib"))
                                    process-environment)))
    (xeft))

Thank you for your quick response.

I tried to compile the code with the libxapian from the beta channel:

/snap/emacs/2541/usr/bin/g++-10 xapian-lite.cc -o xapian-lite.so -shared -fPIC -I/snap/emacs/2541/include -std=c++11 -L/snap/emacs/2541/lib -lxapian

But it still complains about glibc mismatch:

(module-open-failed "/home/fap/.emacs.d/elpa/xeft-3.3/xapian-lite.so" "/snap/emacs/2541/usr/bin/../../lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by /home/fap/.emacs.d/elpa/xeft-3.3/xapian-lite.so)")

This is actually the same error that I get when I compile with the non-snap system:

g++ xapian-lite.cc -o xapian-lite.so -shared -fPIC -I/usr/local/include -std=c++11 -L/usr/local/lib -lxapian

Error:

(module-open-failed "/home/fap/.emacs.d/elpa/xeft-3.3/xapian-lite.so" "/snap/emacs/2541/usr/bin/../../lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by /home/fap/.emacs.d/elpa/xeft-3.3/xapian-lite.so)")

Yes this is expected - as I said, you also need to specify --sysroot - something like the following may be enough

/snap/emacs/current/usr/bin/g++-10 --sysroot /snap/emacs/current/ xapian-lite.cc -o xapian-lite.so -shared -fPIC  -std=c++11 -lxapian

Oh, sorry overread the part about --sysroot.
Thank you so much for your quick help, xeft works now!

I've opened a PR on xeft: casouri/xeft#34
