Fvwm3 build failure - ice.pc package not found

Hi, this is John. I have just tried to build fvwm3(February 9, 2025) and got an error message. I am using the meson build instructions on the latest release tarball. Here it is :

meson.build:195:15: ERROR: Dependency “ice” not found, tried pkgconfig and cmake

Here is the relevant log file output :

Called: /usr/bin/pkg-config --modversion ice → 1
stderr:
Package ice was not found in the pkg-config search path.
Perhaps you should add the directory containing `ice.pc’
to the PKG_CONFIG_PATH environment variable
Package ‘ice’ not found

Can anyone point me toward a solution? I searched for ice.pc on the internet and found nothing and I could not find anything in the forums or FAQ’s. Thanks.

You are missing the development headers for libice, on Debian systems they are in the package libice-dev.
