freebsd gmake libエラー：未定義の参照

Question

私たちはfreebsd gccコンパイラを使用しました。私の使用されたcmakeコマンドは、多くのエラーを言う。

あり：FreeBSDでは

Answer 1

デフォルトC++標準ライブラリはlibc++で、デフォルトのコンパイラが打ち鳴らすです。あなたのgccはlibc++のヘッダを受け取っているようですが、リンクはlibstdc++です。

どちらのベースのコンパイラを使用してコードをコンパイル、またはGCCに-Wl,-rpath=/usr/local/lib/gcc{5,6,7}を渡します。そして、ports/packagesからgccをインストールしたことを確認してください。
