When CONFIG_SYS_SUPPORTS_ZBOOT is not enabled, we will still try to build the decompressor code in arch/mips/boot/compressed as a dependency for producing the vmlinuz target and this will result in the following build failure: OBJCOPY arch/mips/boot/compressed/vmlinux.bin arch/mips/boot/compressed/decompress.c: In function 'decompress_kernel': arch/mips/boot/compressed/decompress.c:105:2: error: implicit declaration of function 'decompress' make[1]: *** [arch/mips/boot/compressed/decompress.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [vmlinuz] Error 2 This is a genuine build failure because we have no implementation for the decompress() function body since no kernel compression method defined in CONFIG_KERNEL_(GZIP,BZIP2...) has been enabled. arch/mips/Makefile already guards the install target for the "vmlinuz" binary with a proper ifdef CONFIG_SYS_SUPPORTS_ZBOOT, we now also do the same if we attempt to do a "make vmlinuz" and show that CONFIG_SYS_SUPPORTS_ZBOOT is not enabled.
