Build C compiler errors when building from source on RHEL v8.9

[hhue13]

Due to issues running switcher 0.8.1 om REL8 (see issue 104 I tried to build it from source using the 0.8.1 source package. The OS I'm running is RedHat Enterprise Linux 8.9 on x86_64.

x@y: /dev/shm/kubeswitch-0.8.1$ uname -a
Linux x.a.b 4.18.0-513.9.1.el8_9.x86_64 #1 SMP Thu Nov 16 10:29:04 EST 2023 x86_64 x86_64 x86_64 GNU/Linux

x@y: /dev/shm/kubeswitch-0.8.1$ cat /etc/redhat-release 
Red Hat Enterprise Linux release 8.9 (Ootpa)

However when running the make all of the downloaded source package I'm running into issues with the C compiler invocation. No matter if I try to compile using clang or gcc.

Compiler versions I've tested with are:
gcc

x@y: /dev/shm/kubeswitch-0.8.1$ gcc -v

The strange thing is however that the go binary is being built nevertheless as hack/switch/switcher_linux_amd64 and this still seems to work well - at least using local store.

So I'm wondering what's causing the compile error and what are the consequences of the failed compile (as the go binary is built anyhow).

Thanks for the detailed report. I'll try to look into the issue.
