c++ - 构建 parquet-cpp 时如何静态链接 Arrow？

Question

来自parquet-cpp home page :

By default, Parquet links to Arrow's shared libraries. If you wish to statically-link the Arrow symbols instead, pass -DPARQUET_ARROW_LINKAGE=static.

我确实想静态链接 Arrow，因为我想在其他未安装 Arrow 的服务器上使用我的程序。我尝试了 -DPARQUET_ARROW_LINKAGE=static，但我收到有关“缺少传递依赖项”的错误:

# cmake -DPARQUET_BUILD_TESTS=Off -DCMAKE_BUILD_TYPE=Release -DPARQUET_MINIMAL_DEPENDENCY=ON -DPARQUET_ARROW_LINKAGE=static .

CMake Error at CMakeLists.txt:515 (message):
  Missing transitive dependencies for Arrow static linking

所以我found the code产生错误:

  if (NOT DEFINED ENV{BROTLI_STATIC_LIB_ENC} OR
      NOT DEFINED ENV{BROTLI_STATIC_LIB_DEC} OR
      NOT DEFINED ENV{BROTLI_STATIC_LIB_COMMON} OR
      NOT DEFINED ENV{SNAPPY_STATIC_LIB} OR
      NOT DEFINED ENV{ZLIB_STATIC_LIB} OR
      NOT DEFINED ENV{LZ4_STATIC_LIB} OR
      NOT DEFINED ENV{ZSTD_STATIC_LIB})
    message(FATAL_ERROR "Missing transitive dependencies for Arrow static linking")

但这并没有真正帮助我，因为我不知道如何定义这些环境变量。

我需要自己编译Arrow然后安装吗？ (我宁愿让 parquet-cpp 为我做这件事。)

我安排了一个脚本来下载依赖源、设置环境变量并在最后运行你的 cmake 行。只需更改 DEPDIR 变量值，将其设置为所选目录即可。

#!/bin/bash

CMKDIR=$PWD
DEPDIR=/tmp

cd $DEPDIR

#snappy
git clone https://github.com/google/snappy.git
cd snappy
mkdir build 
cd build 
cmake ..
make

export SNAPPY_STATIC_LIB=$DEPDIR/snappy/build/libsnappy.a

cd $DEPDIR

#brotli
git clone https://github.com/google/brotli.git
cd brotli
mkdir out
cd out
../configure-cmake
make

export BROTLI_STATIC_LIB_ENC=$DEPDIR/brotli/out/libbrotlienc-static.a
export BROTLI_STATIC_LIB_DEC=$DEPDIR/brotli/out/libbrotlidec-static.a
export BROTLI_STATIC_LIB_COMMON=$DEPDIR/brotli/out/libbrotlicommon-static.a

cd $DEPDIR

#zlib
git clone https://github.com/madler/zlib.git
cd zlib
./configure
make

export ZLIB_STATIC_LIB=$DEPDIR/zlib/libz.a

cd $DEPDIR

#lz4
git clone https://github.com/lz4/lz4.git
cd lz4
make

export LZ4_STATIC_LIB=$DEPDIR/lz4/lib/liblz4.a

cd $DEPDIR

#zstd
git clone https://github.com/facebook/zstd.git
cd zstd
make

export ZSTD_STATIC_LIB=$DEPDIR/zstd/lib/libzstd.a

cd $CMKDIR

cmake -DPARQUET_BUILD_TESTS=Off -DCMAKE_BUILD_TYPE=Release -DPARQUET_MINIMAL_DEPENDENCY=ON -DPARQUET_ARROW_LINKAGE=static

这个脚本很简单，但应该有效。只需将它复制到一个新文件中(在同一个 CMakeLists.txt 目录中)，为该文件授予执行权限(即 sudo chmod +x filename)并像这样执行它:

./filename.sh 

关于fPIC选项问题，您需要编辑一些文件:

snappy:在 CMakeLists.txt 的开头，在前两行之后添加这一行:

set(CMAKE_POSITION_INDEPENDENT_CODE ON)

lz4 和 zstd:编辑 lib 子目录中的 Makefile，在此行之后

CFLAGS  += $(DEBUGFLAGS) $(MOREFLAGS)

添加这一行:

CFLAGS += -fPIC

zlib:在这一行之后编辑 Makefile

CFLAGS=-O3 -D_LARGEFILE64_SOURCE=1 -DHAVE_HIDDEN

添加这一行:

CFLAGS += -fPIC

brotli:据我从 make 输出中看到的，该选项已经设置。

在再次运行 make 之前，执行这个脚本:

#!/bin/bash

DEPDIR=/tmp

cd $DEPDIR/snappy/build
cmake ..
make clean
make

cd $DEPDIR/lz4
make clean
make

cd $DEPDIR/zstd
make clean
make
