eosio_build.sh llvm exists error

[fabifrank]

When running

./eosio_build.sh

I get the error:

mkdir: wasm-compiler: File exists
fatal: destination path 'llvm' already exists and is not an empty directory.
    Unable to clone llvm repo @ https://github.com/llvm-mirror/llvm.git.
    Exiting now.

Independent from whether llvm is inside the directory, already installed with brew, unlinked etc.

Fixed it by:

1. Edit scripts/eosio_build_darwin.sh to delete the llvm folder before git clone (around line 271):

 printf "\n\tChecking LLVM with WASM support.\n"
    if [ ! -d /usr/local/wasm/bin ]; then
      cd ${TEMP_DIR}
      rm -r wasm-compiler
      mkdir wasm-compiler
      cd wasm-compiler                                                                          
      git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git
      if [ $? -ne 0 ]; then
        printf "\tUnable to clone llvm repo @ https://github.com/llvm-mirror/llvm.git.\n"
        printf "\tExiting now.\n\n"
        exit;

1. When error Found PythonInterp: /Users/skober/.pyenv/shims/python2.7 (found version "1.4") appears edit scripts/eosio_build_darwin.sh to point to your python installation with the cmake option -DPYTHON_EXECUTABLE=/<path>/.pyenv/shims/python in the relevant section (wasm on my side, which is the last section in the script).

2. On this error:

[sisardor]

You said scripts/eosio_build_darwin.sh and but didn't say what to do, what to edit? Explain little bit more?

[fabifrank]

@sisardor Updated the post. Does it help now?
And please add mention with @ notation, otherwise I dont get a notification.

[pacificcode]

@fabifrank @sisardor on darwin remove the directory /tmp/wasm-compiler
rm -rf /tmp/wasm-compiler
And run the eosio_build.sh script again and you should be good to go.

[fabifrank]

@pacificcode Yeah that should work in case there's no other error in the build process. Which was not the case on my side.
