So, I'm compiling a program from source, and the compilation fails when it tries to link "libustdio.so":
/usr/bin/ld: cannot find -lustdio
I'm pretty sure that its part of the ICU library, which I have already installed the libicu48 and libicu-dev packages. Is there a way to figure out for sure if "libustdio.so" is a part of libicu48 or libicu-dev packages? If so, then why is the library missing, and how do I fix this?
