building OpenCV on Ubuntu (Undefined reference to `g_memdup2’)

Question

How would you safely go about what appears to be an outdated (or too new) version of libpangosft on Ubuntu, when building OpenCV from source on Ubuntu 22.04?

[ 18%] Linking CXX executable ../../bin/opencv_test_core
/usr/bin/ld: /lib/x86_64-linux-gnu/libpangoft2-1.0.so.0: undefined reference to `g_memdup2'
collect2: error: ld returned 1 exit status

I have followed from the official OpenCV build guide both with and without opencv_contrib, while also using -DBUILD_TIFF=ON due to an earlier incompatibility to system installed libraries.

This is with Ubuntu 22.04.

$ apt list libglib2.0-*
libglib2.0-dev-bin/jammy-updates,jammy-security,now 2.72.4-0ubuntu2.3 amd64 [installed,automatic]

libglib2.0-dev is already the newest version (2.72.4-0ubuntu2.3).

Can you try ldd /lib/x86_64-linux-gnu/libpangoft2-1.0.so.0 and check which library is "not found"? — kiner_shah

Also, try cmake --build . --verbose so you can see the exact build command that failed. (found at stackoverflow.com/a/63690389) — Florian Echtler

I have the same versions of the mentioned libraries and it compiled clean for me. What exact version of opencv are you building? — Ted Lyngmo

Include the output from apt list libglib2.0-* in your question please. — Ted Lyngmo

It is a GLib error, as this function should be presented from any version of GLib since 2.68. Maybe, it is necessary to update the libpango-dev installation. Also, I suppose, there could be a linking issue when the test executable opencv_test_core is not declared explicitly linked to GTK library set due to some unhandled case in the build scenario. This could be fixed using something like this trick.

As a case in point for similar cases, how do we trace back from the original error message, that it is a GLib error?

g_memdup2 is a Glib function

Just for the record, in my specific case after uninstalling Anaconda it builds as is.
