Building on macOS 10.13 with Xcode 9 fails with:

libtool -dynamic -flat_namespace -install_name libcodegen.4.1.2.dylib -lSystem -compatibility_version 4.1 \

when running make -C src install

I'm having a similar issue. Reduced example:

#!/bin/sh
echo 'int main(void) { return 0; }' > test.c
clang -c test.c
SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk \
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool \
-v -dynamic -o test.dylib test.o

➝

+ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld -arch_multiple -arch x86_64 -dylib -dynamic -all_load -force_cpusubtype_ALL -no_arch_warnings /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/dylib1.o test.o -o test.dylib 
ld: file not found: 
fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: internal link edit command failed

After up to a few dozen runs, it eventually executes successfully.

It randomly (and frequently) happens with any local projects as well when building dylibs. I remember a similar issue after upgrading to Sierra, which was resolved by disabling parallel builds. Parallel builds are still disabled, and the issue came back right after upgrading to High Sierra.

I received a reply from Apple, where this was confirmed to be a libtool (cctools) issue which will be addressed in a future Xcode release. Apple suggested to replace libtool -dynamic with $CC -dynamiclib (which is the recommended way to create dylibs) to get around the problem.

On MacOS 11 I had to also remove -lSystem and -framework Accelerate from that libtool command line to get it to link libcodegen.4.1.2.dylib
