PostgreSQL で実行する SOCI ライブラリを構築しようとしています。私は次の手順に従いました：

  • Ubutu 15.10 に PostgreSQL をインストールする
  • SOCIソースコードをダウンロード
  • SOCI コードを抽出する

次に、次のコマンドを実行します。

mkdir build
cd build
cmake -G "Unix Makefiles" -DWITH_BOOST=OFF -DWITH_POSTGRESQL=ON -DPOSTGRESQL_INCLUDE_DIR=/usr/local/pgsql/include -DPOSTGRESQL_LIBRARIES=/usr/local/pgsql/lib ../soci

この時点で、CMake は次の警告を出しました。

WARNING: Target "soci_postgresql" requests linking to directory "/usr/local/pgsql/lib".  Targets may link only to libraries.  CMake is dropping the item.
WARNING: Target "soci_postgresql_static" requests linking to directory "/usr/local/pgsql/lib".  Targets may link only to libraries.  CMake is dropping the item.

ビルドに固執して、次に実行makeしましたが、次のエラーで失敗します。

CMake の警告とビルド エラーの原因は何でしょうか?

少し異なるオプションでcmakeを呼び出してみてください

cmake -G "Unix Makefiles" -DWITH_BOOST=OFF -DWITH_POSTGRESQL=ON \
  -DPOSTGRESQL_INCLUDE_DIR:STRING="/usr/local/pgsql/include" \
  -DPOSTGRESQL_LIBRARIES:STRING="/usr/local/pgsql/lib" ../soci
