I just update to xCode10 – xCode 9 wasn't returning this error.
Whenever I try to build using openframeworks ios 10.0.0 I receive this error
/clang:-1: linker command failed with exit code 1 (use -v to see invocation)
but calling clang on my terminal I receive this
❯ clang --version
Apple LLVM version 10.0.0 (clang-1000.10.44.2) .
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
Any idea on how to fix this?
I just encountered a similar issue with building in xCode 10 as well. Following the steps (both removing the flags for quicktime and in my case removing references to the i386 architecture build settings) here fixed it for me: https://forum.openframeworks.cc/t/xcode-10-0-build-errors/30447
Hope this helps!

Background information
I am trying to install AFL on MacOS X, and have been following the instructions on https://reverse.put.as/2017/07/10/compiling-afl-osx-llvm-mode/.
When I type $make in terminal, the following error appears.
[*] Checking for working 'llvm-config'...
[*] Checking for working '/opt/local/bin/clang'...
[-] Oops, can't find '/opt/local/bin/clang'. Make sure that it's in your $PATH (or set $CC and $CXX).
make: *** [test_deps] Error 1
I noticed that clang is located in /Library/Developer/CommandLineTools/usr/bin.
Here is the details when I type clang -v in terminal:
Apple clang version 11.0.3 (clang-1103.0.32.62)

Question
How do I move clang to the following directory '/opt/local/bin/clang'? Or is there any other thing I can do to fix this problem?
I am getting the following error when I try to compile cpprestsdk:

I have maxOS High Sierra with:
$ g++ --version

I had a same problem. The fix is simple, try this:
go to your websocketpp folder, switch to master branch and pull the latest changes. It worked for me.
My mac version is Sierra. Xcode 8.0

I think gcc is not problem. My project build option is -print-multi-os-directory. but my gcc unsupported... what's the problem???
thanks
on mac your GCC is Clang as you may see in output
in clang option -print-multi-os-directory is unsupported
On current trunk (line 2079)
Was marked as unsupported here
You may try to install pure gcc via brew install gcc command
Also why do you need this option? Do you have any special checks in you project ?(this option just print path )
Since you are trying to build binutils:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=bfd/configure;h=97693870c462d5e5231bd2b512a76b7c271b9133;hb=7fa393306ed8b93019d225548474c0540b8928f7#l10348
Try to figure out why you get in condition when multi-os option is used.
This happened because your compiler passed test:
I'm trying to use the Undefined Behavior Sanitizer by building like this
gcc -fsanitize=undefined add.c -o add
also
clang -fsanitize=undefined -O add.c -o add
In both cases, I'm getting a file not found error:
ld: file not found: /Library/Developer/CommandLineTools/usr/bin/../lib/clang/8.0.0/lib/darwin/libclang_rt.ubsan_osx_dynamic.dylib
This is the output I get when running gcc -v and clang -v

According to this news release, it is available in GCC and also the original homepage for it says it's been merged into LLVM. The linked to article says GCC 4.9 has it, which I assume I have (at least --the version numbering seems different but the article was written a few years ago and I have updated my system several times).
Question: how can I build an executable to use UBSan?
According to blog Friday Q&A 2015-07-03: Address Sanitizer
by Mike Ash:
Any idea why Apple clang doesn't support -fsanitize=undefined?
When I try that I get:
clang -fsanitize=undefined ub.c
...
ld: file not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/
bin/../lib/clang/8.0.0/lib/darwin/libclang_rt.ubsan_osx_dynamic.dylib

If you use -fsanitize=address,undefined it works. Hopefully this
helps anyone else who finds this post search for that error like I did.
Its not an ideal solution for us since they are separate components, and we have limited control over the environment and tools. We had to suspend some Address Sanitizer testing because Asan produces incorrect results with GCC inline assembly and use of ebp/rbp as a general purpose register. And here, the environment and tools are provided by Travis CI.
A bug report was filed with LLVM at Issue 33201, Apple Clang bundled with Xcode 8 does not reject -fsanitize=undefined when it should. It may be closed as off-topic since its an Apple Clang bug (we don't have an iTunes account to file the bug with Apple).
In order to use the undefined behavior sanitizer, I had to install and build LLVM with clang as well as libcxx and libcxxabi, even though my MacOS already came with a version of clang. (with the result that I now I have two versions of clang installed on my computer). From the llvm getting started page
cd where-you-want-llvm-to-live
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
cd where-you-want-llvm-to-live
cd llvm/tools
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
cd where-you-want-llvm-to-live
svn co http://llvm.org/svn/llvm-project/libcxx/trunk libcxx
svn co http://llvm.org/svn/llvm-project/libcxxabi/trunk libcxxabi
Now, I can use the undefined behavior sanitizer by running
/usr/local/bin/clang -fsanitize=undefined -O add.c -o add
$ make dependencies

I have GNU Make 3.81 installed. Also, I did:
$ xcode-select -p

$ gcc --version

I am on a Mac OS X. It could be linked to zsh since I installed it not too long ago and I believe that all my xcode related tools worked just fine before.
Thanks for any help or indication that can point me in the right direction to fix this.
Update
c++ code that I was trying to build is for ubuntu 14
lsb_release is a command that runs on Linux only: the "LSB" stands for "Linux Standard Base" and this refers to a standard baseline set of tools and libraries that Linux distributions can elect to support.
Your makefile should not be invoking that command, since it's not portable to OS X. I'd say that whatever code you're trying to build is not ported to OS X and will only build on Linux. But since you didn't provide any other details, we can't say for sure.
