我很困惑为什么libiconv.so.2
并且libcharset.so.1
两者都没有找到,但只有当我对不同的用户使用 sudo 时。LD_LIBRARY_PATH 完全相同,因为我使用 -E 运行 sudo:
$ ldd `which git`
linux-vdso.so.1 => (0x00007fff51975000)
libz.so.1 => /usr/lib64/libz.so.1 (0x0000003e60600000)
libiconv.so.2 => /internal/lib/libiconv.so.2 (0x00007f0962bdd000)
libcrypto.so.6 => /lib64/libcrypto.so.6 (0x0000003e6a400000)
libcharset.so.1 => /internal/lib/libcharset.so.1 (0x00007f09629db000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003e61600000)
libc.so.6 => /lib64/libc.so.6 (0x0000003e60a00000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000003e61200000)
/lib64/ld-linux-x86-64.so.2 (0x0000003e60200000)
$ sudo -ucgaadm -EH ldd `which git`
linux-vdso.so.1 => (0x00007fff5b148000)
libz.so.1 => /usr/lib64/libz.so.1 (0x0000003e60600000)
libiconv.so.2 => not found
libcrypto.so.6 => /lib64/libcrypto.so.6 (0x0000003e6a400000)
libcharset.so.1 => not found
libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003e61600000)
libc.so.6 => /lib64/libc.so.6 (0x0000003e60a00000)
libdl.so.2 => /lib64/libdl.so.2 (0x0000003e61200000)
/lib64/ld-linux-x86-64.so.2 (0x0000003e60200000)
只需检查 LD_LIBRARY_PATH,似乎 libiconv.so.2 的路径确实存在:
$ echo $LD_LIBRARY_PATH
...
$ sudo -ucgaadm -EH echo $LD_LIBRARY_PATH
... same output as previous command ...
从我的常规使用以及 sudo 用户中也可以看到应该包含这些库的目录:
$ ls /internal/lib/ -lah
