Error building for macOS

[rruipinheiro]

Hello,

I'm having problems compiling the obfuscator llvm on macOS.
Any suggestion?

**LLVM: ** 14.0.6
**macOS SDK: ** 13.0

Output error

Hi @rruipinheiro,

Are you building from a machine with an x86_64 CPU or an ARM one (Apple M1) ?

[rruipinheiro]

Hi @PatriceBlin,
From a x86_64 CPU machine

[PatriceBlin]

Looks like we are missing at least a link with LLVMTransformUtils

Could you try the following change ?

diff --git a/CMakeLists.txt b/CMakeLists.txt
index bcc03d2..8d93263 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -38,7 +38,7 @@ add_library(LLVMObfuscator SHARED Plugin.cpp)
 target_include_directories(LLVMObfuscator PRIVATE ${CMAKE_SOURCE_DIR})
 target_include_directories(LLVMObfuscator PRIVATE ${CMAKE_CURRENT_BINARY_DIR})
 
-target_link_libraries(LLVMObfuscator LLVMCore LLVMSupport)
+target_link_libraries(LLVMObfuscator LLVMCore LLVMSupport LLVMTransformUtils)
 
 option(BUILD_DUMMY "Build dummy plugin" OFF)
 if(BUILD_DUMMY)

Might not resolve all missing symbols, but at least reduce the list.

[rruipinheiro]

I manage to get it to work by adding the link LLVMInterpreter and target_link_libraries(LLVMObfuscator "$<$<PLATFORM_ID:Darwin>:-undefined dynamic_lookup>")
