From d11fa9c16b8f50788c07e22bd742177d14e435b2 Mon Sep 17 00:00:00 2001 From: Sergei Trofimovich Date: Mon, 30 Dec 2019 15:53:41 +0000 Subject: [PATCH] include: fix 'ulong' definition on musl targets The build failure was originally reported on arm64-musl target at https://bugs.gentoo.org/703132. Here is the amd64-musl variant: ``` $ LANG=C make CROSS_COMPILE=x86_64-gentoo-linux-musl- tools-only_defconfig -j$(nproc) $ LANG=C make CROSS_COMPILE=x86_64-gentoo-linux-musl- tools-all -j$(nproc) ... In file included from tools/env/../../env/flags.c:7, from tools/env/env_flags.c:1: include/env.h:159:1: error: unknown type name 'ulong'; did you mean 'long'? 159 | ulong env_get_ulong(const char *name, int base, ulong default_val); | ^~~~~ | long ``` Note: 'ulong' is not defined there. On glibc 'ulong' comes from : ```c /* Old compatibility names for C types. */ typedef unsigned long int ulong; ``` On musl it comes from as well but from under different guards: ```c typedef unsigned long u_long, ulong; ``` The change inlines 'ulong' define similar to 'uint' define.
