glib-2.72 build fails with during linking to libglib-2.0.so0.7200.0

Question

*The hardware environment I am working in is a QNAP NAS with x86_64 architecture. The software is a headless, embedded, QNAP-designed Debian-based Gnu/Linux distro based on kernel 4.14.24.

My current issue is in compiling glib-2.72.0, which uses the meson-ninja system, under Python 3.9. Compilation runs fine The ninja build fails at

[150/1259] Linking target glib/libglib-2.0.so.0.7200.0
FAILED: glib/libglib-2.0.so.0.7200.0

when, I think, it attempts to link all the *.c.o files listed in the command below:

collect2: error: ld returned 1 exit status

Is this is an issue with gettext? All the *.c.o files in the failed command exist in the correct directory.

The prefix=/opt Gettext 0.21 is installed. gettext.h is located in /opt/share/gettext/ and this path is included in CFLAGS and CPPFLAGS libintl.a is in opt/lib as is its shared library:

 # ldconfig -v |grep libintl
        libintl.so.8 -> libintl.so.8.2.0

I would like to learn why this is failing and how to fix it.

Many thanks
