[SOLVED] dyld error When Including Debug Symbols In native C Library

dyld error When Including Debug Symbols In native C Library

I am developing a C library and have a test harness program that links against the library to test functionality. When buiding for testing, I want both the test harness and the library to have debug symbols as I am using the Address Sanitizer and Leak Sanitizer to detect memory issues.

Library Compile Command

/opt/homebrew/opt/llvm/bin/clang -dynamiclib  -framework ApplicationServices -lcups  lib/macos/*.c -o ./test/macos/libTest.dylib -Wall -Werror -Wextra -fvisibility=hidden -current_version 1.0 -compatibility_version 1.0 -arch arm64 -arch x86_64  -fno-limit-debug-info -g

Note that I am using -fno-limit-debug-info -g to include debug symbols

Harness Compile Command

/opt/homebrew/opt/llvm/bin/clang ./test/macos/*.c -o ./test/macos/run -L ./test/macos -lTest -Wall -Werror -Wextra -g -fsanitize=address -fsanitize-address-use-after-return=runtime -fsanitize-address-use-after-scope -fno-optimize-sibling-calls -O1

Also using -g here to include debug symbols

Test Harness Invocation

ASAN_OPTIONS=detect_stack_use_after_return=1 ASAN_OPTIONS=detect_leaks=1 ./test/macos/run

However, when I run the test harness, I am getting the following runtime error

dyld[3025]: Library not loaded: /var/folders/hp/b8x1q6697_129jnylkn87kh40000gp/T/capability-e861fd/capability-arm64.out

If I remove the -g option when compiling the library, I can successfully run the test harness. However, I do not get debug symbols in the Address Sanitizer report when referencing code inside the compiled library.

Is there some other way I should include debug symbols in the C library? Any pointers would be very appreciated!

Solution

I was able to identify the combination of flags when compiling the library that caused this error.

If I compiled with -arch arm64 -arch x86_64 to build a fat binary that can be loaded on both architectures, then I would get this runtime error. However, removing these flags and just including an arm64 build would allow the library to load with no issue.
