# Known Issues
## relocation error with glibc < 2.32
**Severity: High**
**Task:** [ziglang/zig relocation error: symbol pthread_sigmask version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference #7667](https://github.com/ziglang/zig/issues/7667)
Background: one of our internal shared libraries (which we must build with glibc 2.28) does not load on an older system:
```
id: relocation error: /lib/x86_64-linux-gnu/libnss_uber.so.2: symbol pthread_sigmask, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference
```
Severity is high, because there is no known workaround: the shared library,
when built with this toolchain, will not work on our target system.
## using glibc 2.27 or older
**Severity: Low**
@ -87,21 +72,10 @@ Background: when glibc 2.27 or older is selected, it may miss `fcntl64`. A
workaround is applied for `x86_64`, but not for aarch64. The same workaround
may apply to aarch64, but the author didn't find a need to test it (yet).
## incorrect glibc version autodetection
**Severity: Low**
**Task:** [ziglang/zig zig detects wrong libc version #6469](https://github.com/ziglang/zig/issues/6469)
Background: zig detects an incorrect glibc version when not specified.
Therefore, until the task is resolved, registering a GNU toolchain without a
version suffix (e.g. `linux_amd64_gnu`) is not recommended. We recommend
specifying the suffix to the oldest system that is mean to run the compiled
binaries. This is safe, because glibc is backwards-compatible. Alternatively,
use musl.
