私はspatialiteライブラリを構築し、次にspatialiteをサポートするgdalライブラリを構築しました。gdal に依存する mapserver の構築も成功しました。リンクには問題ありませんでした。
gdal ユーティリティを実行しようとすると、次のようになります。
$ ogrinfo.exe
/usr/local/bin/ogrinfo.exe: error while loading shared libraries: cyggdal-1.dll: cannot open shared object file: No such file or directory
しかし、すべて問題ないようです:

cyggdal-1.dll を現在のフォルダーにコピーすると、次のようになります。
$ ogrinfo.exe
/usr/local/bin/ogrinfo.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
では、「?」とは何ですか? 図書館?
