Cygwin 库加载错误

我构建了 Spatialite 库，然后构建了支持 Spatialite 的 gdal 库。还成功构建了依赖于 gdal 的 mapserver。链接没有问题。

当我尝试执行 gdal 实用程序时，我得到：

$ 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

但一切似乎都很好：

$ ldd /usr/local/bin/ogrinfo.exe
        ntdll.dll => /cygdrive/c/WINDOWS/system32/ntdll.dll (0x7c900000)
        kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x7c800000)
        cyggdal-1.dll => /usr/local/bin/cyggdal-1.dll (0x710c0000)
        cygcurl-4.dll => /usr/bin/cygcurl-4.dll (0x63d80000)
        cyggcc_s-1.dll => /usr/bin/cyggcc_s-1.dll (0x67f00000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0x61000000)
        ADVAPI32.DLL => /cygdrive/c/WINDOWS/system32/ADVAPI32.DLL (0x77dd0000)
        RPCRT4.dll => /cygdrive/c/WINDOWS/system32/RPCRT4.dll (0x77e70000)
        Secur32.dll => /cygdrive/c/WINDOWS/system32/Secur32.dll (0x77fe0000)
        cygcrypto-0.9.8.dll => /usr/bin/cygcrypto-0.9.8.dll (0x6ba40000)
        cygidn-11.dll => /usr/bin/cygidn-11.dll (0x6c200000)
        cygiconv-2.dll => /usr/bin/cygiconv-2.dll (0x674c0000)
        cygintl-8.dll => /usr/bin/cygintl-8.dll (0x6f5c0000)
        cygssh2-1.dll => /usr/bin/cygssh2-1.dll (0x69ec0000)
        cygz.dll => /usr/bin/cygz.dll (0x692c0000)
        cygssl-0.9.8.dll => /usr/bin/cygssl-0.9.8.dll (0x63400000)
        cygexpat-1.dll => /usr/bin/cygexpat-1.dll (0x66ec0000)
        cyggeos_c-1.dll => /usr/bin/cyggeos_c-1.dll (0x70180000)
        cyggeos-3-1-1.dll => /usr/bin/cyggeos-3-1-1.dll (0x4e0000)
        cygjpeg-7.dll => /usr/bin/cygjpeg-7.dll (0x66e00000)
        cygpng12.dll => /usr/bin/cygpng12.dll (0x6f200000)

如果我将 cyggdal-1.dll 复制到当前文件夹：

$ ogrinfo.exe
/usr/local/bin/ogrinfo.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

那么什么是“？”库？

$ ldd cyggdal-1.dll
        ntdll.dll => /cygdrive/c/WINDOWS/system32/ntdll.dll (0x7c900000)
        kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x7c800000)
        ??? => ??? (0x710c0000)
        ??? => ??? (0x63d80000)
        ??? => ??? (0x67f00000)
        ??? => ??? (0x61000000)

        ??? => ??? (0x69ec0000)
        ??? => ??? (0x692c0000)
        ??? => ??? (0x63400000)
        ??? => ??? (0x66ec0000)
        ??? => ??? (0x70180000)

        ??? => ??? (0x66e00000)
        ??? => ??? (0x6f200000)

这些“???”是什么？如何解决这个问题？

答案1

使用cygcheck /usr/bin/[yourbinary]（示例/usr/bin/curl）

它会告诉您无法找到的任何内容。（它会说“无法找到 [some.dll]”。）

只需安装 dll 命名的包。

例如-当我跑步时：

$ curl

返回结果：

/usr/bin/curl.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

于是我跑了：

$ cygcheck /usr/bin/curl

返回结果：

cygcheck: track_down: could not find cygsasl2-2.dll

所以我安装了“libsasl2”包。

它是一个通过 setup.exe（cygwin 安装程序）安装的运行时库，并且 curl 开始正常工作。

答案2

我使用 cmd 执行该实用程序，它显示了一个带有丢失的 dll 名称的弹出窗口。

答案3

就我而言，我想安装 SSH。 它抱怨缺少“ cyggssapi-3.dll ”，我重新安装了 Cygwin 并确保没有安装任何额外的东西，并安装了正确版本的 SSH + SSL。
