用Mac裝eosio可能會遇到的兩個問題

最新 06-27

Mac上執行./eosio_build.sh，由於網路或Mac本身系統的問題，經常會出現兩個問題：

問題1： LLVM NOTFOUND

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

Could not find a package configuration file provided by "LLVM" (requestedversion 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 beeninstalled.

這是

解決方法：查找路徑，移除，重裝

find /usr -name LLVMConfig.cmake -print 2>/dev/null

然後

brew remove --force llvm

rm -rf build/

git submodule update --init --recursive

export LLVM_DIR=/usr/local/Cellar/llvm@4/4.0.1/lib/cmake

./eosio_build.sh

/dev/null ：在類Unix系統中，/dev/null，是一個特殊的設備文件，它丟棄一切寫入其中的數據（但報告寫入操作成功），讀取它則會立即得到一個End Of File。

- 開發過程中，經常會有把一部分個公共庫分離出來，是整個項目具有復用性和模塊化，這就是git submodule的由來

git submodule update --init --recursive的動作是確保submodule被更新下載，並把路徑註冊在本地(register path)出來

在eos中submodule有以下一些

位於contracts下：

contracts/libc++/upstream（https://github.com/EOSIO/libcxx.git）

contracts/musl/upstream（https://github.com/EOSIO/musl.git）

位於externals下：

externals/binaryen（https://github.com/EOSIO/binaryen）

externals/magic_get（https://github.com/EOSIO/magic_get）

位於libaries下：

libraries/appbase（https://github.com/eosio/appbase）

libraries/chainbase（https://github.com/eosio/chainbase）

libraries/fc（https://github.com/EOSIO/fc）

libraries/softfloat（https://github.com/eosio/berkeley-softfloat-3）

EOShenzhen在未來的文章會講解這些庫的原理

問題 2: Boost_INCLUDE_DIR not found

Make Error: The following variables are used in this project, but they are set to NOTFOUND.

Please set them or make sure they are set and tested correctly in the CMake files:

/Users/mac/Desktop/mainnet/eos/libraries/appbase/Boost_INCLUDE_DIR

used as include directory in directory /Users/mac/Desktop/mainnet/eos/libraries/appbase /Users/mac/Desktop/mainnet/eos/libraries/chainbase/Boost_INCLUDE_DIR

used as include directory in directory /Users/mac/Desktop/mainnet/eos/libraries/chainbase

/Users/mac/Desktop/mainnet/eos/libraries/fc/Boost_INCLUDE_DIR

used as include directory in directory /Users/mac/Desktop/mainnet/eos/libraries/fc

/Users/mac/Desktop/mainnet/eos/tools/Boost_INCLUDE_DIR

used as include directory in directory

/Users/mac/Desktop/mainnet/eos/tools

Boost_INCLUDE_DIR (ADVANCED)

used as include directory in directory /Users/mac/Desktop/mainnet/eos/contracts/proxy

解決方法

解決思路和LLVM類似，即尋找到boost存儲的路徑、移除，並重裝

find / -name boost

如果./eosio_build.sh在一次安裝過程中由於網路或者系統的問題出現問題，可能會導致一系列的問題
