在centos+openwrt 15.05.01下编译owntone

Openwrt中如何单独编译某一个模块：

make package/owntone/download #- download the soures of example
make package/owntone/prepare #- extract the sources, apply patches and download if necessary
make package/owntone/clean

1.安装owntone依赖：

sudo apt-get install \
  build-essential git autotools-dev autoconf automake libtool gettext gawk \
  gperf bison flex libconfuse-dev libunistring-dev libsqlite3-dev \
  libavcodec-dev libavformat-dev libavfilter-dev libswscale-dev libavutil-dev \
  libasound2-dev libxml2-dev libgcrypt20-dev libavahi-client-dev zlib1g-dev \
  libevent-dev libplist-dev libsodium-dev libjson-c-dev libwebsockets-dev \
  libcurl4-openssl-dev libprotobuf-c-dev

2.下载owntone源码

下载
https://github.com/owntone/owntone-openwrt/tree/master/owntone
放到package目录下。里面的代码不是最新，要修改makefile：
PKG_SOURCE:=(PKG_NAME)-(PKG_VERSION).tar.xz
PKG_SOURCE_URL:=https://github.com/owntone/owntone-server/releases/download/(PKG_VERSION)/
PKG_HASH:=98538566a993638ec569fc44ea2c7a7fcb5dd925c47b84b64ac2d63fc8b056b8
修改 package/owntone/Makefile 文件，
将 -std=c99 选项添加到 TARGET_CFLAGS 变量中。
找到 TARGET_CFLAGS +=(FPIC) 这一行，并在其前面添加以下代码：
TARGET_CFLAGS += -std=c99
修改后的 Makefile 文件应该如下所示：
TARGET_CFLAGS += -std=c99
TARGET_CFLAGS += $(FPIC)

3.在make menuconfig，在sound里面选择owntone

4.开始编译

“` make -j1 V=s package/owntone/compile #- compile example, prepare and download if necessary “`

先尝试编译owntone,如果没有问题，
接下来开始编译整个工程make -j1 V=s

5.除错。编译过程中会出现各种错误

 File "./configure", line 992, in <module>
    configure_node(output)
  File "./configure", line 530, in configure_node
    o['variables']['gcc_version'] = 10 * cc_version[0] + cc_version[1]
IndexError: tuple index out of range
Makefile:72: recipe for target '/root/mt7628-wireless-audio/wireless-music/build_dir/host/node-v0.12.7/.configured' failed

解决方案：

您在 Ubuntu 18.04 上编译 MT7628 无线音频项目时遇到的错误，源于 Node.js v0.12.7 的 configure 脚本中使用了 gcc -dumpversion 来获取 GCC 的版本号。然而，从 GCC 7 开始，-dumpversion 默认只返回主版本号（例如 "7"），而不包括次版本号（例如 "7.5"）。这导致脚本在解析版本号时出现 IndexError: tuple index out of range 的错误。

为了解决此问题，您可以修改 configure 脚本中的相关代码，将 -dumpversion 替换为 -dumpfullversion，后者会返回完整的版本号。

请按照以下步骤操作：

定位并编辑 configure 脚本：

在您的项目目录中，找到并打开 configure 脚本。

查找以下代码行：
proc = subprocess.Popen(CC.split() + ['-dumpversion'], stdout=subprocess.PIPE)
将其修改为：
proc = subprocess.Popen(CC.split() + ['-dumpfullversion'], stdout=subprocess.PIPE)
这样，脚本将使用 gcc -dumpfullversion 来获取完整的版本号。

在编译openwrt时遇到了如下错误，
checking for CONFUSE... no
configure: error: Package requirements (libconfuse >= 3.0) were not met:
Requested 'libconfuse >= 3.0' but version of confuse is 2.7
Consider adjusting the PKG_CONFIG_PATH environment variable if you

你完全可以在 保持目录结构不变的情况下修改 Makefile 来升级版本，这是最直接的方法。

Step 1:
编辑你现有的 feeds/packages/libs/confuse/Makefile：
PKG_VERSION:=3.0
PKG_SOURCE:=(PKG_NAME)-(PKG_VERSION).tar.xz
PKG_SOURCE_URL:=https://github.com/libconfuse/releases/download/v$(PKG_VERSION)/
PKG_MD5SUM:=c534b51a2118ed57031dc548032304a3
Step 2: 
清除旧缓存
rm -rf dl/confuse*
make package/confuse/clean
Step 3: 
获取源码并编译
make package/confuse/download V=s
make package/confuse/prepare V=s
make package/confuse/compile V=s

checking for LIBEVENT... no
configure: error: Package requirements (libevent >= 2.1.4) were not met:

Requested 'libevent >= 2.1.4' but version of libevent is 2.0.22-stable

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Step 1: 下载
https://github.com/libevent/libevent/releases/download/release-2.1.10-stable/libevent-2.1.10-stable.tar.gz

修改makefile:
vim  feeds/packages/libs/libevent/Makefile

PKG_NAME:=libevent
PKG_VERSION:=2.1.10
PKG_RELEASE:=1

PKG_BUILD_DIR:=(BUILD_DIR)/libevent-(PKG_VERSION)-stable
PKG_SOURCE:=libevent-(PKG_VERSION)-stable.tar.gz
PKG_SOURCE_URL:=https://github.com/libevent/libevent/releases/download/release-(PKG_VERSION)-stable/
PKG_MD5SUM:=999caf86f52943af2363bc8077f00167
PKG_MAINTAINER:=Steven Barth <[email protected]>

Step 2: 清除旧缓存
make package/libevent/clean

Step 3: 获取源码并编译
make package/libevent/download V=s
make package/libevent/prepare V=s
make package/libevent/compile V=s

如果还不行，修改 owntone 的 Makefile
将 +libevent2 改为 +libevent：
- DEPENDS:=+libevent2 +libdaemon +confuse +alsa-lib +libffmpeg-full \
+ DEPENDS:=+libevent +libdaemon +confuse +alsa-lib +libffmpeg-full \

将 package/libs/libevent2 升级为 libevent 2.1.10，以满足 owntone 对 libevent >= 2.1.4 的依赖，同时保持 libevent2 这个名字不变，确保依赖链兼容。

修改 package/libs/libevent2/Makefile 的方法
你当前的 Makefile 很完整，只需要以下几个关键改动：

步骤一：更新版本和下载地址
PKG_VERSION:=2.1.10
PKG_SOURCE:=libevent-(PKG_VERSION)-stable.tar.gz
PKG_SOURCE_URL:=https://github.com/libevent/libevent/releases/download/release-(PKG_VERSION)-stable/
PKG_MD5SUM:=999caf86f52943af2363bc8077f00167
PKG_BUILD_DIR:=(BUILD_DIR)/libevent-(PKG_VERSION)-stable

步骤二：修正 install 段
libevent-2.1.10 的 so 文件后缀从 libevent_core-2.0.so.X 变为 libevent_core-2.1.so.X，因此你的 install 部分需要支持 2.1：

修改这几段安装逻辑（加星号表示要修改）：
define Package/libevent2/install
        (INSTALL_DIR)(1)/usr/lib
        (CP)(PKG_INSTALL_DIR)/usr/lib/libevent-2.1.so.* (1)/usr/lib/        # ★ 修改这里的版本号
endef

define Package/libevent2-core/install(INSTALL_DIR) (1)/usr/lib(CP) (PKG_INSTALL_DIR)/usr/lib/libevent_core-2.1.so.*(1)/usr/lib/   # ★ 修改这里
endef

define Package/libevent2-extra/install
        (INSTALL_DIR)(1)/usr/lib
        (CP)(PKG_INSTALL_DIR)/usr/lib/libevent_extra-2.1.so.* (1)/usr/lib/  # ★
endef

define Package/libevent2-openssl/install(INSTALL_DIR) (1)/usr/lib(CP) (PKG_INSTALL_DIR)/usr/lib/libevent_openssl-2.1.so.*(1)/usr/lib/ # ★
endef

define Package/libevent2-pthreads/install
        (INSTALL_DIR)(1)/usr/lib
        (CP)(PKG_INSTALL_DIR)/usr/lib/libevent_pthreads-2.1.so.* $(1)/usr/lib/ # ★
endef

修改完毕后，强烈建议清理并重新构建：

make package/libevent2/clean
rm -rf build_dir/target-*/libevent-*
make package/libevent2/download V=s
make package/libevent2/compile V=s

确认 .pc 文件：

cat staging_dir/target-*/usr/lib/pkgconfig/libevent.pc | grep Version
应该输出：Version: 2.1.10

通过 OpenWrt 的 feed 系统将 ffmpeg 更新到 4.4 或更高版本，手动将新版 FFmpeg 添加到 feed 中（推荐）

你可以从较新 OpenWrt（如 22.03）分支中复制 ffmpeg 4.4 的 Makefile 和相关文件，替换你本地 feed 中的旧版本：

步骤如下：
第一步：备份当前旧版本
mv feeds/packages/multimedia/ffmpeg feeds/packages/multimedia/ffmpeg.old
第二步：从 GitHub 上拉取新版本的 feed
以 OpenWrt 22.03 分支（ffmpeg 4.4）为例：

git clone https://github.com/openwrt/packages.git -b openwrt-22.03 openwrt-packages-22.03

git checkout a68e9db8d4c3a29c86261cd6bb1933fab1cc3a35

commit a68e9db8d4c3a29c86261cd6bb1933fab1cc3a35 (HEAD)
Author: Josef Schlehofer <[email protected]>
Date:   Sat Jan 29 11:34:56 2022 +0100

ffmpeg: update to version 4.3.3

Signed-off-by: Josef Schlehofer <[email protected]>


cp -r openwrt-packages-22.03/multimedia/ffmpeg feeds/packages/multimedia/

你也可以只复制必要文件：

cp openwrt-packages-22.03/multimedia/ffmpeg/Makefile feeds/packages/multimedia/ffmpeg/
cp -r openwrt-packages-22.03/multimedia/ffmpeg/patches feeds/packages/multimedia/ffmpeg/
cp -r openwrt-packages-22.03/multimedia/ffmpeg/files feeds/packages/multimedia/ffmpeg/

第三步：更新 feed 和 make
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig   # 确保 libffmpeg-full 被选中
make package/ffmpeg/clean
make package/ffmpeg/compile V=s

libavutil/libm.h

+/* Disable MIPS optimized libm due to toolchain incompatibility */
+#if 0
+#if HAVE_MIPSFPU && HAVE_INLINE_ASM
+#include "libavutil/mips/libm_mips.h"
+#endif
+#endif

更新libcurl

git clone https://github.com/openwrt/packages.git -b openwrt-22.03 openwrt-packages-22.03
git checkout a68e9db8d4c3a29c86261cd6bb1933fab1cc3a35

把package下面的curl文件复制到openwrt 15.05那边，修改makefile取消对ssl的支持
make package/curl/clean
make package/curl/compile V=s

patch文件

fast_copy(int fd_dst, int fd_src)
{
  // Here we use kernel-space copying for performance reasons
#if defined(__APPLE__)
  return fcopyfile(fd_src, fd_dst, 0, COPYFILE_ALL);
#else
  struct stat fileinfo = { 0 };
  ssize_t bytes_copied;

  fstat(fd_src, &fileinfo);
  bytes_copied = copy_file_range(fd_src, NULL, fd_dst, NULL, fileinfo.st_size, 0);
  if (bytes_copied < 0 || bytes_copied != fileinfo.st_size)
    return -1;

  return 0;
  #endif
}

   if (gcry_cipher_open(&hd, GCRY_CIPHER_CHACHA20, GCRY_CIPHER_MODE_POLY1305, 0) != GPG_ERR_NO_ERROR)
                             ^
outputs/airplay.c:619:29: note: each undeclared identifier is reported only once for each function it appears in

                                                   ^
make[7]: *** [outputs/airplay.o] Error 1

解决方案一：升级 libgcrypt
找到你 OpenWrt 源码里的 package/feeds/packages/libgcrypt/Makefile
把版本号改为 1.8.x 或 1.9.x，比如：
PKG_VERSION:=1.8.8
PKG_SOURCE:=libgcrypt-(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=https://gnupg.org/ftp/gcrypt/libgcrypt/
PKG_VERSION:=1.8.8
PKG_SOURCE:=libgcrypt-(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=https://gnupg.org/ftp/gcrypt/libgcrypt/
PKG_MD5SUM:=4ada2c473f9ae5aff41dd9d08a4a7727

删除旧版本的 build_dir：
make package/libgcrypt/clean
重新编译 libgcrypt：
make package/libgcrypt/compile V=s

确认 staging_dir/target-*/usr/include/gcrypt.h 中有这两个宏：
#define GCRY_CIPHER_CHACHA20 ...
#define GCRY_CIPHER_MODE_POLY1305 ...
再编译 owntone。
