[Samba] Build error while compiling 4.9.8 when using gcc 4.8.5

[Alex Braunegg]

Hi all,

 

In attempting to build Samba 4.9.8 on CentOS 6 using mock, but using Kernel
4.19.46 as a base, Samba failed to compile spitting out the following error:

Compiling the same Samba package, but using Kernel 4.4.180, Samba 4.9.8
compiles successfully without issue. The only difference between each build
environment is below:

 


Works

Fails


kernel-4.4.180-1.el6.src.rpm

kernel-4.19.46-1.el6.src.rpm


gcc-4.6.2-1.el6.src.rpm

The package upgrades were essentially needed to support the newer 4.19.x
kernel series to compile successfully and to support CONFIG_RETPOLINE
(Compile kernel with the retpoline compiler options to guard against
kernel-to-user data leaks by avoiding speculative indirect branches). In
terms of kernel configuration - these are pretty much the same.

 

Reading the lists this issue has been seen before
(https://lists.samba.org/archive/samba/2018-December/219926.html), however
on both build systems the following is installed in the build root, and the
'older' gcc (4.6.2) seems to handle what rpcgen is generating.

Just wondering if anyone has any suggestions as where to look further in
solving this.

 

Best regards,
