In the Vc project, OptimizeForArchitecture.cmake is used to optimize compilation for specific architectures.
In my project, I used the old version of the above file. After I update it to the newest version, the compilation flags in flags.make files have the following flags seperated by semicolons:
-march=broadwell;-msse2;-msse3;-mssse3;-msse4.1;-msse4.2;-mavx;-mfma;-mbmi2;-mavx2
which accouts for the following errors when compiling:
/bin/sh: 1: -msse2: not found
/bin/sh: 1: -msse3: not found
/bin/sh: 1: -mssse3: not found
/bin/sh: 1: -msse4.1: not found
/bin/sh: 1: -msse4.2: not found
/bin/sh: 1: -mavx: not found
/bin/sh: 1: -mfma: not found
/bin/sh: 1: -mbmi2: not found
/bin/sh: 1: -mavx2: not found
While when compiling the Vc project, there are no semicolons between the flags.
What's the possible reason of this problem?
A flags.make file example: build/release/CMakeFiles/tungsten.dir/flags.make
CXX_FLAGS = -std=c++0x -march=broadwell;-msse2;-msse3;-mssse3;-msse4.1;-msse4.2;-mavx;-mfma;-mbmi2;-mavx2 -mno-sse4a -mno-xop -mno-fma4 -mno-avx512f -mno-avx512vl -mno-avx512pf -mno-avx512er -mno-avx512cd -mno-avx512dq -mno-avx512bw -mno-avx512ifma -mno-avx512vbmi -Wall -Wextra -Wpointer-arith -Wcast-align -fstrict-aliasing -Wno-unused-local-typedefs -Wno-misleading-indentation -Wno-maybe-uninitialized -Wno-int-in-bool-context -Wno-implicit-fallthrough -fvisibility-inlines-hidden -O3 -DNDEBUG

Can anyone help me with this issue?
In order to use dealii, I tried to install p4est using the command
./configure && make && make install
and
cmake .. -DP4EST_DIR=/usr/local -DDEAL_II_WITH_P4EST=ON -DDEAL_II_WITH_MPI=ON -DCMAKE_INSTALL_PREFIX=/usr/local
under "build" folder, but some error occurs.
I also opened the file dealii-9.0.0/build/CMakeFiles/CMakeError.log, it says:
Source file was:

I guess I haven't installed p4est correctly, so I configure it again.
# p4est-2.8 ./configure --enable-mpi.
( Here shows we are using MPI. I also tried p4est-2.8 ./configure --enable-mpi --prefix=/usr/local)
Then I tried to build and install p4est, but it gives me an error during installation:

I see that contrafold-se installation has been tested on certain versions of g++ but I am using a macbook, and when I run g++ --version, I get:

In one of my projects I'm using git submodules to download the SDL2 Library and compile it. This is giving me a strange error so I tried to compile SDL2 Standalone and I got the same error.
I'm on a 13" MacBook Pro Big Sur
Steps to reproduce:
git clone https://github.com/libsdl-org/SDL.git
cd SDL
cmake . -Bbuild
make -C ./build
The error I get is

The message would imply that Apple's own SDK files don't compile, but that can't be right. What's even stranger is that I'm using git submodules with SDL2 in another project but that compiles successfully and I can't find any discernible difference between this and the other project.
Edit:
I user make -C ./build VERBOSE=1 to compare the output with the project that successfully compiled and the project that failed to compile.

The only difference between the successfully compiled project and the project that failed to compile is the MacOS SDK version. The one that failed to compile used MacOS SDK 12 while the successful one used MacOS 11.3. Until this is fixed a temporary solution is to downgrade your MacOS SDK to 11.3.

I have installed the package ncurses which apparently should provide the erase char symbol. I cannot find anything useful on Google.
Explicitly link the tinfo library.
NCurses uses tinfo, from what I have read ncurses should include the tinfo functionality in it's own library, maybe this has changed recently.

This flag is used on ARM architectures. If you are compiling under x86/amd64, just remove it.
