make errors

[bsburns]

Getting the following errors when trying to build on:
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-1160.71.1.el7.x86_64

cmake version: 3.24.2
make: GNU Make 3.82
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

The error I'm seeing is:

My guess is the support of C++14 by your version of gcc (4.8 is quite old).
Do you have the possiblity to use a more recent one? You can also try clang, if the version is more recent or support C++14.
For instance, with cmake, you can override the default compiler (gcc) by your clang installation if any with:

cd build                         (note: a fresh 'build' repository is required by cmake to change the compiler)
export CXX=/usr/bin/clang++      (to adapt with your setup's path and name) 
export CC=/usr/bin/clang
cmake .. 
make

The relevant part is that zstd/common/fse_decompress.c are compiled with clang but CXX flags are provided.

/home/fabi/palanteer/server/external/zstd/common/fse_decompress.c -o build/temp.linux-x86_64-3.8/home/fabi/palanteer/server/external/zstd/common/fse_decompress.o -DUSE_PL=1 -DPL_EXPORT=1 -DBS_NO_GRAPHIC -DPL_NOCONTROL=1 -DPL_NOEVENT=1 -std=c++14 -I /home/fabi/palanteer/c++ -I /home/fabi/palanteer/server/base -I /home/fabi/palanteer/server/common -I /home/fabi/palanteer/server/external/zstd -I /home/fabi/palanteer/server/external/zstd/common -I /home/fabi/palanteer/server/external/zstd/compress -I /home/fabi/palanteer/server/external/zstd/decompress -DPL_GROUP_BSVEC=0
error: invalid argument '-std=c++14' not allowed with 'C'

So as you can see your CMake configuration is adding the CXX flag -std=c++14 to a C compilation.
