編譯 Systemd 獨立二進製文件時遇到問題

來源：systemd-stable-251：https ://github.com/systemd/systemd-stable

wget https://github.com/systemd/systemd-stable/archive/refs/heads/v251-stable.zip
unzip v251-stable.zip 
cd systemd-stable-251-stable/

使用命令：

./configure --auto-features=disabled \
           --default-library=static \
           -D standalone-binaries=true \
           -D static-libsystemd=true \
           -D static-libudev=true \
           -D link-udev-shared=false \
           -D link-systemctl-shared=false \
           -D link-networkd-shared=false \
           -D link-timesyncd-shared=false \
           -D link-boot-shared=false && make

還嘗試僅使用靜態庫並僅啟用獨立選項。

配置：

使用者定義選項 auto_features : 禁用 default_library : 靜態 link-boot-shared : false link-networkd-shared : false link-systemctl-shared : false link-timesyncd-shared : false link-udev-shared : false 獨立二進製文件 : true static -libsystemd：真靜態libdev：真

共享對象：

# file build/udevadm
build/udevadm: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=f6b7c1a3509d45ebcafda9b49f4dd2332e786738, with debug_info, not stripped

我期待看到一個 ELF 執行檔而不是共享對象文件。

選項的文件standalone-binaries說：

還建構支持的二進製文件的獨立版​​本

這似乎充其量是模棱兩可的。查看meson_build文件，我們發現：

       if have_standalone_binaries
               exe = executable(
                       'systemd-sysusers.standalone',

[...]

       if have_standalone_binaries
               exe = executable(
                       'systemd-tmpfiles.standalone',

[...]

這似乎表明該選項僅影響systemd-sysusersand systemd-tmpfiles，實際上，當建構完成時，我們看到：

$ ls build/*.standalone
build/systemd-sysusers.standalone build/systemd-tmpfiles.standalone

看起來事情正在按設計執行。
