link failed in mac os.

[philsong]

I am writing a article about how to compile eos in mac os.
http://www.jianshu.com/p/f26ee4cf1d4a

but i still meet a issue in below:
could some one help me? thanks.

Have you tried with llvm from homebrew rather than installing it manually?

[hh3755]

Same problem here,I install the llvm manually instead of using brew install llvm

with the following cmake command:

export WASM_LLVM_CONFIG=~/develop/eos/environment/wasm-compiler/llvm/bin/llvm-config
## using manually installed llvm
export LLVM_DIR=~/develop/eos/environment/llvm/clang-llvm-4.0.0-x86_64-apple-darwin/lib/cmake/llvm
cmake -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2l -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2l/lib ..

if i didn't use the manually install llvm,I got the following error when cmake:

- Configuring ChainBase on OS X

CMake Error at libraries/wasm-jit/Source/Runtime/CMakeLists.txt:26 (find_package):

Could not find a package configuration file provided by "LLVM" (requested

version 4.0) with any of the following names:

LLVMConfig.cmake

llvm-config.cmake

Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set

"LLVM_DIR" to a directory containing one of the above files.  If "LLVM"

provides a separate development package or SDK, be sure it has been

installed.

-- Configuring incomplete, errors occurred!

and then cmake succeed, but when make -j4,I will got another error,any help will be appreciated,thanks.

@hh3755 Which Xcode version do you use? I am not sure if it's related with the XCode. When I tried to compile, I have many problems. And upgrade the Xcode >=8.3.3 solve that.

[philsong]

resolved:
see my update:
http://www.jianshu.com/p/f26ee4cf1d4a

the core change:

echo "export WASM_LLVM_CONFIG=~/wasm-compiler/llvm/build/bin/llvm-config" >> ~/.zshrc

echo "export LLVM_DIR=/usr/local/Cellar/llvm/4.0.1/lib/cmake/llvm" >> ~/.zshrc

[hh3755]

@skenan I'm using brew, not install xcode directly. And @philsong 's method worked.

After using:

brew install llvm

brew install the version of llvm@4.0.1 for me,changed the coresponding LLVM_DIR ,run the cmd like following:

export WASM_LLVM_CONFIG=~/develop/eos/environment/wasm-compiler/llvm/bin/llvm-config
export LLVM_DIR=/usr/local/Cellar/llvm/4.0.1/lib/cmake/llvm
cmake -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2l -DOPENSSL_LIBRARIES=/usr/local/Cellar/openssl/1.0.2l/lib ..

Then everything went ok. Thanks everybody.

solved by: brew install gmp

[nathanielhourt]

This issue has tracked several different errors at this point, I think, and I'm not sure if any of them are still outstanding, so I'm closing it. Open a new issue if some problems persist.

[heifner]

This should be closed. Looks like it was reopened on accident. Closing.

[facadev]

Tweaking the environment variables doesn't fix the issue for me.

I tried building LLVM from source, installing llvm (v4 and v5) with brew and modifying relevant environment variables to ensure the build script finds the right LLVM, LLC, clang binaries. Neither works.
