I am cross compiling a Lazarus program, creating a 32bit program on a 64bit Ubuntu 14.04 Trusty Tahr system, and everything apparently compiles to the very end when I get this messsage

/usr/bin/ld: cannot find -lglib-2.0

What is the full name of the library whose absence results in this error mesage?

libc6-dev:i386 appears to be the most likely library, but when I try to install it with apt indicates build-essential g++ gcc gcc-multilib will be removed so I abort it.

sudo apt-get install libc6-dev:i386

It turns out it was the libglib2.0-0:i386 package. It was already installed earlier, but it had not been fully configured.

It was present in the /lib/i386-linux directory and I had to create a symlink to it include it to the fpc.cfg configuration file used by Free Pascal.

locate libglib | grep ^/lib produced:

/lib/i386-linux-gnu/libglib-2.0.so.0
/lib/i386-linux-gnu/libglib-2.0.so.0.4002.0
/lib/x86_64-linux-gnu/libglib-2.0.so.0
/lib/x86_64-linux-gnu/libglib-2.0.so.0.4002.0

I symlinked it with the expected name:

ln -s /lib/i386-linux-gnu/libglib-2.0.so.0 /lib/i386-linux-gnu/libglib-2.0.so

then added to the Lazarus installations fpc.cfg file

#ifdef cpui386
 -Fl/usr/lib32
 -Fl/lib/i386-linux-gnu
#endif
