nzsql:在加载共享库时出错: libcom_err.so.2:错误的ELF类:Ubuntu18.04上的ELFCLASS64

Question

我正在尝试在Ubuntu18.04系统上安装Netezza客户端。安装完毕后，我们看到下面的错误消息

/usr/local/nz$ nzsql
nzsql: error while loading shared libraries: libcom_err.so.2: wrong ELF class: ELFCLASS64

我的诊断步骤：

1. 查找共享libs /usr/local/nzsql linux-gate.so.1 (0xf7f13000) libz.so.1 => /lib/i 386-linux-gnu/libz.so.1 (0xf7ee0000) libkrb5.so.3 => /usr/local/nz/. => /bin/lib/libkrb5.so.3 (0xf7e3a000) libcrypt.so.1 => /lib/i386-linux/libcrypt.so.1 (0xf7e08000) libssl.so.10 =>/usr/nz/bin。. . /lib/ libssl.so.10 (0xf7da5000) libcryp.so.10 => /usr/local/nz/.bin/bin/../lib/libcryp.so.10 (0xf7bf2000) libconv.so.2 => /lib/i 386-linux-gnu/libdrv.so.2 (0xf7bda000) libnsl.so.1 => /lib/i386-linux/libnsl.so.1 (0xf7bbf000) libdl.so.2 => //i 386-linux-gnu/libdl.so.2(0xfb7bba000)libn.curso.5/ => /lib/lib.I 386-linux-gnu/libncurses.so.5 (0xf7b94000) libm.so.6 => /lib/i 386-linux-gnu/libm.so.6 (0xf7a92000) libc.so.6 => /lib/i 386-linux-gnu/libc.so.6 (0xf78b4000) libcom_err.so.3 => /usr/libcom_err.so.3/nz/nz/bin/.lib/libcom_err.so.3 (0xf78b1000) libk5.so.3 => /usr/nz/nz/bin/../lib/lib/lib/0 /usr/local/nz/./bin/../lib/../lib/libkrb5support.so.0 (0xf7879000) libgssapi_krb5.so.2 => /usr/local/nz/./bin/../lib/libgssapi_krb5.so.2 (0xf783e000) /lib/ld-linux.so.2 (0xf7f15000) libcom_err.so.2 =>未找到libtinfo.so.5 => /lib/i 386-linbtinfo.so.5 (0xf781b000)我看到一条“未找到”的消息libcom_err.so.2 =>未找到
2. 尝试安装包/usr/local/nz$ sudo apt-获取ocmsapp的安装libcomerr2密码:读取包列表.创建依赖树读取状态信息..。Done libcomerr2已经是最新版本(1.44.1-1 ubuntu1.2)。以下软件包已自动安装，不再需要:linux 4.15.0-65 linux-headers 4.15.0-65-generic映像-4.15.0-65-通用linux-模块-4.15.0-65-泛型使用'sudo apt自动删除‘来删除它们。0升级，0新安装，0删除，36没有升级。上面说包裹已经到了。
3. 检查已经安装的版本:~$ dpkg -listfiles libcom-err2 /。/usr/share/doc/libcom-err2/changelog.Debian.gz /x86_64-linux-gnu /lib/x86_64-linux-gnu/libcom_err.so.2.1 /usr /usr/share /usr/share/doc /usr/ /lib /libcom-err2-err2 /usr/share/doc/libcom-err2 /lib/x86_64-linux-gnu/libcom_err.so.2
4. 创建一个软链接sudo ln -s /x86_64-linux-gnu/ libcom_err.so.2 libcom_err.so.2，然后我们检查ldd ./bin/nzsql，仍然可以看到未找到的消息libcom_err.so.2 => not，并且一旦我们尝试运行nzsql命令，就会在message /usr/local/nz$ nzsql: error时加载共享库: libcom_err.so.2:错误ELF类: ELFCLASS64

有什么问题，我该怎么解决呢？

Answer 1

您应该通过运行

file /usr/local/nz/bin/nzsql

但是，您的netazza应用程序很可能是x86-64 (即64位)安装上的32位应用程序；您需要安装32位版本的libcomerr2，如下所示：

sudo apt install libcomerr2:i386

以及它所依赖的任何其他系统库。
