Android用に何かをクロスコンパイルしようとしているので、別のツールチェーンを使用しています。リンカが見つからないと文句を言っているライブラリがあります。
arm-eabi-gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found
ライブラリは間違いなくこのパスに存在します：

そのため、コンパイル行に「-L / mnt / hgfs / Documents / thesis / android-wmon / core / os / prebuilts / gcc / linux-x86 / arm / arm-eabi-4.6 / libexec / gcc/arm-」を含めました。 eabi / 4.6.x-google」と入力し、「-lliblto_plugin」を指定します...しかし、引き続きこのエラーが発生します。
これが私の全体の行とエラーです：

別の編集：共有ライブラリを含むディレクトリに移動し、liblto_plugin.soからliblto_plugin.so.0.0.0へのリンクを削除してから、「cp liblto_plugin.so.0.0.0 liblto_plugin.so」に移動すると、正しくリンクされ、私のプログラムはコンパイルされます。このファイルがリンクであるのになぜ壊れているのですか？（申し訳ありませんが、ここで2つの異なるものを参照するために「リンク」を使用しています）。
