Although High Sierra is no longer supported by Homebrew, but I need to install llvm#13 formula as a dependency for other formulas. So I tried to install it this way:
$ brew install llvm

How can I fix that compilation error?
Install llvm with debug mode enabled:
$ brew install --debug llvm
Installation process encounters with the same error mentioned in the question, but some options are provided to fix the issue. Choose option 5:
- raise
- ignore
- backtrace
- irb
- shell
Choose an action: 5
It gives a shell access to the current build directory of llvm formula. Find the current folder:
$ pwd
/private/tmp/llvm-20211109-12151-m0zvtm/llvm-project-13.0.0.src
Change the location to the build directory:
cd llvm/build
Edit the HostInfoMacOSX.mm and remove the second part of condition:
vi ../../lldb/source/Host/macosx/objcxx/HostInfoMacOSX.mm
You need to change the line 246 from:
if (cputype == CPU_TYPE_ARM64 && cpusubtype == CPU_SUBTYPE_ARM64E) {
to:
if (cputype == CPU_TYPE_ARM64) {
Then re-run the last command:
$ cmake --build .
It takes some time to be completed:

==> Caveats
To use the bundled libc++ please add the following LDFLAGS:
LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"
llvm is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have llvm first in your PATH, run:
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.zshrc
For compilers to find llvm you may need to set:
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"

It can be verified this way, the default llvm#10 pre-installed:
$ /usr/bin/clang --version
Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin17.7.0
Thread model: posix

And the new Homebrew version of llvm#13:
$ /usr/local/opt/llvm/bin/clang --version

#HamidRohani provides a great solution for those still tinkering in High Sierra (10.13). Getting a recent version of LLVM to compile on my old MAC with an older XCode (clang version 10.0.1 in my case) was a great help. My nominal contribution...
Alternatively, you could define the symbol after line 41 in HostInfoMacOSX.mm:
// Kludge: Symbol definition extracted from a modern machine.h
#ifndef CPU_SUBTYPE_ARM64E
# define CPU_SUBTYPE_ARM64E ((cpu_subtype_t) 2)
#endif
Now, there's no need to modify line 246. And the definition would resolve any (possible) subsequent references. And let me aggregate the steps shown above conducted in brew's debug-shell:
cmake . -DLLVM_CREATE_XCODE_TOOLCHAIN=On
cmake --build .
cmake --build . --target install
cmake --build . --target install-xcode-toolchain
Regarding the LLVM-related variable, setting LLVM_CREATE_XCODE_TOOLCHAIN to On directs CMake to generate a target named 'install-xcode-toolchain'. 1 The target is a work-around to System Integrity Protection (SIP); "Xcode toolchains are a mostly-undocumented feature that allows multiple copies of low level tools to be installed to different locations, and users can easily switch between them." 2
Brew's Caveats
Brew gives you few caveats necessary to use the new compiler: "because macOS already provides this software and installing another version in parallel can cause all kinds of trouble." To use your new compiler, "You need to have llvm first in your PATH and for compilers to find llvm you may need to set" LDFLAGS and CDFLAGS. But since these gems-of-wisdom appear near the end of a million-lines of output, let me re-iterate here:
export PATH="/usr/local/opt/llvm/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"
Setting PATH is straight forward. I however, didn't need to set LDFLAGS or CPPFLAGS. Further, no joy with this additional caveat, "To use the bundled libc++ please add the following LDFLAGS":
export LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"
Anyway, moving on... To demonstrate that all's good, a C++ foo program that incorporates <filesystem>; a library not in High Sierra:
#include <iostream>
// C++17: Modern C++ compiler has std filesystem
#include <filesystem>
namespace fs = std::filesystem;
typedef std::filesystem::path my_path;
using namespace std;
int main ()
{
fs::path path{"/tmp"};
path /= "foo.txt";
ofstream ofs(path);
ofs << "Hello World." << endl;
ofs.close();
return 0;
}
Clearly, a nonsensical program, But to compile:
unset CPPFLAGS
unset LDFLAGS
clang++ -std=c++17 -L/usr/local/opt/llvm/lib foo.cpp -o foo
Again, showing That I didn't need CPPFLAGS and LDFLAGS. And so, The executable links to the correct libc++ library:
MacIntel:c++fs mjo$ otool -L foo
foo:
/usr/local/opt/llvm/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.50.4)
Enjoy.

It looks like you are missing the postgresql-libs package. Install it using your systems package manager.
For me I needed to install libpq-dev. You can install it on linux like this:
sudo apt install libpq-dev
I have installed mosquitto using the command apt-get install mosquitto. It is installed successfully on my system, but I got version "1.4.5". I want to downgrade to version 1.4.4, so I was trying using the source tar file. Under folder, I am running the command make and it is throwing an error:

What is going wrong here?. Is there any another way to install 1.4.4 version of mosquitto?
Thanks
You're missing dependencies needed for compilation.
Try:
apt-get install libc-ares-dev libssl-dev libwrap0-dev uthash-dev uuid-dev
If you want libwebsockets support you can either install libwebsockets-dev, or better install it manually from source - that will get you version 1.5 instead of the old 1.2 that is in Debian/Ubuntu.
If you install the manually compiled version with
make prefix=/usr install
then it will overwrite the existing binary and you can use it with the existing system services.
Recently I clean installed Yosemite 10.10.2
I also installed gcc using
brew install gcc
Now I'm trying to build and install python and openmpi from source because previously I've had problems with gfortran and clang.
So I did
brew install openmpi --build-from-source -verbose
brew install python --build-from-source -verbose

Error: pkg-config 0.28 did not build
My understanding is that there is a conflict between clang and gcc-4.9 configuration.
I could temporally solve it doing:
brew install pkg-config
So it doesn't build if from source and uses clang configuration.
I see that Xcode is still in the Include and Library path, and I think this prevents linking with gcc-4.9.
How can I install pkg-config using gcc-4.9 only?
Problem solved after following this instructions changing:
typedef void (^dispatch_block_t)(void); // this is for clang
To
typedef void* dispatch_block_t; //this is for gcc-4.9

note: until now, I have no problem installing other module with luarocks that have no dependency with luafilesystem.
Solved, this problem arise because actually I'm not using the same MinGW compiler when building lua52.dll. I don't know which compiler I use at the first time. Thanks to #siffiejoe
