FreeBSD: ldconfig -v Lost Dynamic Linker Configuration

19 Feb 2023Best/Tutorial

If the ldconfig command on FreeBSD reports a "Lost Dynamic Linker Configuration" error message, it means that the system's dynamic linker configuration is broken or missing. This can be caused by a number of factors, such as incorrect permissions or a corrupted file system.

To fix this error, you can follow these steps:

Check if the /var/run/ld-elf.so.hints file exists:
```
ls -l /var/run/ld-elf.so.hints
```
If the file does not exist, you can create it by running the following command:
```
touch /var/run/ld-elf.so.hints
```
Make sure the file has the correct permissions:
```
chmod 644 /var/run/ld-elf.so.hints
```
Rebuild the system's dynamic linker configuration by running ldconfig with the -v option:
```
ldconfig -v
```
This will rebuild the system's dynamic linker cache and update the /var/run/ld-elf.so.hints file.
Verify that the error message is no longer displayed:
```
ldconfig -r | grep lost
```
This command should not return any results, indicating that the "Lost Dynamic Linker Configuration" error has been fixed.

rnNote that if the error persists, it may be a sign of a more serious problem with the system's file system or hardware. In that case, it is recommended to investigate the issue further or seek assistance from a system administrator.
