Question

默认情况下，Parquet链接到Arrow的共享库。如果您希望静态链接箭头符号，请传递-DPARQUET_ARROW_LINKAGE = static。

我确实希望静态链接Arrow，因为我想在其他没有安装Arrow的服务器上使用我的程序。我尝试了-DPARQUET_ARROW_LINKAGE=static，但我收到了关于＆＃34;错过传递依赖关系的错误＆＃34;：

# 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会产生错误：

  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")

但这对我没有帮助，因为我不知道如何定义这些环境变量。

我是否需要先编译Arrow并自行安装？（我宁愿让实木复合地板给我做。）

我安排了一个脚本来下载依赖项源代码，设置环境变量并在最后运行cmake行。只需更改DEPDIR变量值，将其设置为所选目录。

#!/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

此脚本非常简单，但应该有效。只需将其复制到一个新文件中（在相同的CMakeLists.txt目录中），为该文件提供执行权限（即sudo chmod +x filename）并执行它，如下所示：

./filename.sh

关于 fPIC选项问题，您必须编辑一些文件：

snappy ：在前两行之后的CMakeLists.txt中添加此行：

set(CMAKE_POSITION_INDEPENDENT_CODE ON)

lz4 和 zstd ：在此行之后编辑lib子目录中的Makefile

CFLAGS  += $(DEBUGFLAGS) $(MOREFLAGS)

添加以下行：

CFLAGS += -fPIC

zlib ：在此行之后编辑Makefile

CFLAGS=-O3 -D_LARGEFILE64_SOURCE=1 -DHAVE_HIDDEN

添加以下行：

CFLAGS += -fPIC

brotli ：就我从make输出中看到的那样，该选项已经设置好了。

再次运行make之前，请执行以下脚本：

#!/bin/bash

DEPDIR=/tmp

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

cd $DEPDIR/lz4
make clean
make

cd $DEPDIR/zstd
make clean
make

在构建实木复合地板时，如何静态链接箭头？
