[Compile-related issues] Would it be possible to early-warn for missing "-lao not found" problem?
On Linux trying to compile icewm-1.5.4, let me show the error message or build message first:

Not sure about the errors. I have libiconv compiled - does this mean that icewm can not work?
I put the glibc iconv.h in place, and recompiled icewm - it worked past that step but it still failed:
/System/Index/bin/ld: cannot find -lao collect2: error: ld returned 1 exit status make[2]: *** [src/CMakeFiles/icesound.dir/build.make:204: icesound] Error 1 make[1]: *** [CMakeFiles/Makefile2:107: src/CMakeFiles/icesound.dir/all] Error 2 make: *** [Makefile:130: all] Error 2
Not sure what the ao lib is.
I picked this one:
https://ftp.osuosl.org/pub/xiph/releases/ao/libao-1.2.0.tar.gz
And indeed, it worked \o/. So that is -lao I guess.
My suggestion though:
- Would it be possible to add an early check whether libao is available or not, and if not, to notify that libao (when requested, aka default), is not available early on, rather than fail/stop during compilation? It's a tiny issue but still.
Thanks!
You seem to build your system from parts by hand, which gives you an incomplete non-standard result. Also you don't give relevant information about your system to understand the reasons. You may be helped by using the os-depends.sh script from the website.
cmake version basically relies on pkg-config here. If you have a broken installation of libao (i.e. pkg-config script for ao exists but does not output the lib directory flags properly) then sorry, PEBKAC.
I really don't like closing issues on users. I would rather they close them themselves. @rubyFeedback, please close this issue if it is no longer a problem.
