The prototype of xlen_funct has no arguments defined. In C23 declaring a function as int foo() is equivalent as declaring that it takes no argument, hence calling it with arguments becomes an error. See: https://en.wikipedia.org/wiki/C23_(C_standard_revision)#Syntax You can either fix the code or tell the compiler to stick to older versions of the standard, something like: export DEB_CFLAGS_MAINT_APPEND += -std=c17
