Errors while build cpprestsdk using gcc-8.2 - c++

When I try building cpprestsdk with a cross compiler gcc I've the following issue:

If I replace -isystem with a simple -I everything works well...
I know the gcc is working well cos I already built zlib openssl opencv and boost 1.69.
EDIT
To avoid the problem I edited the Makefile generated by cmake and removed -isystem from cxx flags

Try and open a regular CMD (instead of Powershell), making sure it inherits all your previous setups (meaning its %PATH% does reference g++.exe, pip.exe, and so on.

clang-tidy with precompiled headers and cmake does not work

I have a simple setup where CMake produces the following compile command:

When I take --tidy="..." stuff out of the command. It fully compiles, (also if I dont specify PCHs in the CMakeLists.txt) it works.
I am not sure what the problem is exactly.
Do PCH and clang-tidy somehow not work? Why are the include directories somehow missing? I am using LLVM-12, clang-12 on Ubuntu.
Also adding -I/usr/lib/llvm-12/include/c++/v1 does not help.

Why might make produce a different object file than the same command copy-pasted and entered manually?

Sort of related to my other question here, since this is also about building llvm.
When trying to get around a build failure in llvm, I noticed the following:

The searching I did didn't really help; I didn't write the makefile myself (cmake generated), and at least to my eyes there wasn't reason for make to print something that it wasn't executing.
Anyone have any idea what is going on?
Reproduction steps:
install homebrew if it isn't already installed
replace homebrew's llvm formula with the WIP one here
Run brew install llvm --with-clang --with-lldb --verbose --debug
wait for the build to fail and ask you what to do
Drop into a debug shell
cd to projects/compiler-rt/lib/asan
run make clean
run make asan_posix.o (or any of the other *.o files listed in make help
run file on the output file (in CMakeFiles/RTAsan_dynamic.(osx|iossim).dir/asan_posix.cc.o for me)
Repeat the above 3 steps, but copy-pasting the command instead of running make
Edit: Link to my environment in the shell and during the make process.
The solution to this question ended up being the same as the linked question. homebrew was changing compiler flags, so the commands that were printed weren't the ones being executed. The fix in the other question also happened to fix this.

What could cause clang to not find the unordered_map header?

I'm trying to compile a program I found on the web using Clang++. The Makefile generates this command:
clang++ -c -arch x86_64 -msse3 -std=c++11 -stdlib=libstdc++
-Wno-missing-field-initializers -Wno-missing-prototypes -Wreturn-type

-fvisibility-inlines-hidden -funsafe-math-optimizations -ftrapping-math -fno-rtti

But I get
src/main.cpp:23:10: fatal error: 'unordered_map' file not found
#include <unordered_map>
^
1 error generated.
If I compile a simple program that includes <unordered_map> running clang++ test.cpp, it compiles fine.
I'm on
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.3.0

I had the same issue when compiling glogg.
As the comments have pointed out. it was stdlib.
In the makefile after running qmake. Change this line from
CXXFLAGS = -g -Wextra -std=c++11 -DGLOGG_VERSION=\"`cat .tarball-version`\" -O2 -arch x86_64 -Wall -W $(DEFINES)
To this line below
CXXFLAGS = -g -Wextra -std=c++11 -stdlib=libc++ -DGLOGG_VERSION=\"`cat .tarball-version`\" -O2 -arch x86_64 -Wall -W $(DEFINES)
notice "-stdlib=libc++" was specified in the cxxflags. It's autospecified in the linker flags, I guess it also needs to be specified in for the C++ flags.
It says -Wno-c++11-extensions. What wrote that makefile?

Expression is not an integer constant expression

I am using xcode 4.2.1, Apple LLVM compiler 3.0.
Project cleans successfully in xcode and builds successfully from the command line. The problem is the project fails to build in xcode. I feel like I am missing something in my xcode configuration. I have made no edits to the original source I pulled down.

What can I do to get a clean build?
I upgraded xcode to version 4.6.3. The compiler updated to LLVM 4.2 and these problems were resolved. Otherwise I don't know why the previous version was failing.
