I have code, that compile with gcc
gcc --version
Apple clang version 14.0.0 (clang-1400.0.29.102)
Target: arm64-apple-darwin21.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
without errors
But in Xcode I have errors. For example:
error build: Undefined symbol: _element_from_bytes_compressed

Building my project I get error:
ld: library not found for -lglfw
clang: error: linker command failed with exit code 1 (use -v to see invocation)
But I have installed glfw, via brew install glfw
brew list --versions | grep glfw
glfw 3.2.1
ls /usr/local/lib | grep glfw
libglfw.3.2.dylib
libglfw.3.dylib

Looks like adding export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib to ~/.bash_profile solved the problem, but I'm not sure if it's ellegant solution without side effects.
I am trying to compile simple C code on my system. I am running gcc version (4.9.2) on macOS 10.11.6.
ld: library not found for -lgcc
collect2: error: ld returned 1 exit status
I am unable to fix this issue. This problem is not letting me install any ./configure packages as well since they require gcc to work.
Even if there is a program called gcc under macOS, it is not a real gcc compiler. It is just a Clang compiler, as you can prove easily:
gcc --version
will print:
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

You should be able to compile and link your program by omitting the -lgcc flag from the command line.
I know that recent Mac OS X versions don't use gcc (g++). When I type gcc or g++ the OS actually uses Clang (cc).
Now, I'm running OS X 10.8.2 with LLVM version 4.2 (clang-425.0.28), installed through XCode:
$ g++ --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)
Target: x86_64-apple-darwin12.2.0

However, buried in the file system there's another more recent Clang version:
$ clang --version
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin12.2.0
Thread model: posix
How can I force gcc to "link" Clang 503... instead of Clang 425...?
Install Xcode, which will give you the latest available versions of both:
xcode-select --install
...
$ g++ --version

I already install xcode(version 8.0)
There is a strange doubtful point: xcode 8.0's clang version is 8.0, but brew use 7.x.

I solved it after I update my system to macOS Sierra.
I met a usual error—— symbol(s) not found for architecture x86_64，but for an unusual reason. I have searched for a long time and found some methods，but they didn't work.
Anyone can help me?Thanks.there are some parameter about my Mac below:
