FFmpeg 構建錯誤 pkg-config 找不到 x265 /usr/bin/ld: 找不到 -lnuma: 沒有那個文件或目錄

Question

我正在嘗試使用源代碼中的自定義庫構建 ffmpeg。

我的腳本中的每個 package 都按應有的方式構建，但是當它有時間使用所有包運行 ffmpeg 構建時，它會失敗，並在 ffmpeg 構建日志的底部顯示一個奇怪的錯誤代碼。

BEGIN /home/jman/tmp/ffconf.JouXp6kg/test.c
    1   #include <x265.h>
    2   #include <stdint.h>
    3   long check_x265_api_get(void) { return (long) x265_api_get; }
    4   int main(void) { int ret = 0;
    5    ret |= ((intptr_t)check_x265_api_get) & 0xFFFF;
    6   return ret; }

有誰知道這個-lnuma指的是什么？

就在幾天前，當我最后一次運行我的構建腳本時我沒有遇到任何問題，然后突然出現了這個問題。

這是我的完整構建腳本： FFmpeg-build.sh

更新：Per Allan Winds 的說明是 output：

find /usr/lib -name libnuma\* -ls

Answer 1

這意味着您的構建在嘗試鏈接numa庫時失敗。 linker 將使用內置路徑以及 -L 指定的路徑搜索庫。 具體來說，-lnuma 將搜索 libnuma.a 和 libnuma.so（per man ld(1)）。 從 libnuma.so 到實際庫的符號鏈接鏈接是 libnuma-dev package。您安裝 package 時：

sudo apt install libnuma-dev

-dev package 取決於實際庫 libnuma1。 如果需要，您可以直接使用-l:libnuma.so.1而不是-lnuma指定版本庫。
