這篇文章給大家分享的是有關如何使用源碼編譯BeeGFS搭建開發環境的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。
如果我們需要動態調試和開發BeeGFS，那么就需要自己手動編譯了，而且能夠用最簡單的方式運行起來，下面就講解自己探索和分析的過程。
安裝依賴的軟件包：
$ yum install -y libuuid-devel libibverbs-devel librdmacm-devel libattr-devel redhat-rpm-config rpm-build xfsprogs-devel cppunit cppunit-devel zlib-devel openssl-devel sqlite sqlite-devel ant gcc-c++ gcc redhat-lsb-core java-devel
獲取指定版本的源碼：
$ git clone https://git.beegfs.io/pub/v6.git beegfs-v6 $ cd beegfs-v6 $ git tag -l 6.1 6.10 6.11 6.12 6.13 6.14 6.15 6.16 6.17 6.18 6.19 6.2 6.3 6.4 6.5 6.6 6.7 6.8 6.9 $ git checkout -b v6.18 6.18
進行簡單的查看和驗證：
$ git show 6.18 | head -n12 tag 6.18 Tagger: Bernd Lietzow <bernd.lietzow@itwm.fraunhofer.de> Date: Mon Mar 12 16:09:35 2018 +0100 created tag 6.18 commit aee03250ea19502952d2f187e73134996abaec5b Author: Bernd Lietzow <bernd.lietzow@itwm.fraunhofer.de> Date: Mon Mar 12 16:09:13 2018 +0100 updated to release 6.18 $ git branch -av master 4a69532 updated to release 6.19 * v6.18 aee0325 updated to release 6.18 remotes/origin/HEAD -> origin/master remotes/origin/master 4a69532 updated to release 6.19
查看他的Makefile，BeeGFS自己實現了一個簡單的Makefile工程模板，所有的子模塊都使用這一套模板來變異，十分簡單高效：
$ make -j$(nproc) -C beegfs_meta/build help [VER] BEEGFS_VERSION="19.5-git8" BEEGFS_VERSION_CODE=18023688 make: Entering directory `/root/beegfs-v6/fhgfs_meta/build' Optional arguments: BEEGFS_DEBUG=1 Enables debug information and symbols BEEGFS_DEBUG_OPT=1 Enables internal debug code, but compiled with optimizations CXX=<compiler> Specifies a c++ compiler DISTCC=distcc Enables the usage of distcc V=1 Print command lines of tool invocations BEEGFS_COMMON_PATH=<path> Path to the beegfs_common directory BEEGFS_OPENTK_PATH=<path> Path to the beegfs_opentk_lib directory BEEGFS_THIRDPARTY_PATH=<path> Path to the beegfs_thirdparty directory Targets: all (default) build only clean delete compiled files help print this help message rpm create an rpm package deb create debian package file make: Leaving directory `/root/beegfs-v6/fhgfs_meta/build' $ cat beegfs_meta/build/Makefile # This is the beegfs_meta makefile. # It creates an ELF executable. # # Use "make help" to find out about configuration options.

查看他構建RPM包的方法，直接打包源碼目錄，并使用一個RPM SPEC文件模板，使用sed動態生成一個SPEC文來進行構建：
$ cat beegfs_meta/build/make-rpm
#!/bin/bash
NAME=beegfs-meta
SPEC_FILE=${NAME}.spec
source ../../beegfs-version
arch=`uname -m`
if [[ "$arch" == "x86_64" ]]; then
BUILDARCH="$arch"
elif [[ "$arch" =~ 86 ]]; then
BUILDARCH="i686"
else
BUILDARCH=$arch
fi
CONCURRENCY=${MAKE_CONCURRENCY:-4}
export BEEGFS_VERSION_PATH=`pwd`/../../beegfs-version
set -e
pushd ../
TOOLS_ROOT=`pwd`
popd
BUILD="${TOOLS_ROOT}/build"
mkdir -p $BUILD/buildroot/{BUILD,RPMS,S{RPMS,PECS,OURCES}}
rm -f $BUILD/buildroot/SOURCES/*.tgz
ROOT_DIR=${ROOT_DIR:-`(cd ../..; pwd)`}
BEEGFS_COMMON_PACKAGE_PATH=${BEEGFS_COMMON_PACKAGE_PATH:-`readlink -f ../../beegfs_common_package`}
set +e
# test if redhat-rpm-config is installed. If so, we must not specify
# %debug_package in the spec file, if not installed we need to define it
# in order to strip binaries and to build a debug package
rpm -qa redhat-rpm-config | grep redhat-rpm-config
NEED_DEBUG_DEFINE=$?
set -e
pushd $TOOLS_ROOT
tar czf $BUILD/buildroot/SOURCES/${NAME}-${BEEGFS_VERSION}.tgz --exclude=buildroot/* *
cd $BUILD
sed -e "s#%BEEGFS_COMMON_PACKAGE_PATH%#$BEEGFS_COMMON_PACKAGE_PATH#g" \
-e "s/%NAME%/$NAME/g" \
-e "s/%BEEGFS_VERSION%/$BEEGFS_VERSION/g" \
-e "s/%BUILDARCH%/$BUILDARCH/g" \
-e "s/%MAKE_CONCURRENCY%/$CONCURRENCY/g" \
-e "s/%NEED_DEBUG_DEFINE%/$NEED_DEBUG_DEFINE/g" \
${SPEC_FILE}.in > ${SPEC_FILE}
rpmbuild --clean -bb ${SPEC_FILE} --define "_topdir $BUILD/buildroot/" -D "ROOT_DIR $ROOT_DIR"
popd
rm -fr /var/tmp/${NAME}-root/
rm -f /var/tmp/rpm-tmp.*查看SPEC中引用的參數，正式上面的腳本替換后的結果：
$ cat beegfs_meta/build/beegfs-meta.spec

beegfs_meta/build/beegfs-meta.spec:74: root-dir=%{ROOT_DIR} \先編譯依賴的函數庫：
$ make -j$(nproc) -C beegfs_thirdparty/build $ make -j$(nproc) -C beegfs_opentk_lib/build $ make -j$(nproc) -C beegfs_common/build
根據需要編譯所需的模塊：
$ make -j$(nproc) -C beegfs_meta/build clean # make -j$(nproc) -C beegfs_meta/build BEEGFS_DEBUG=1 $ make -j$(nproc) -C beegfs_meta/build [VER] BEEGFS_VERSION="19.5-git9" BEEGFS_VERSION_CODE=18023689 make: Entering directory `/root/beegfs-v6/fhgfs_meta/build' [CXX] ../source/app/App.cpp.o [CXX] ../source/components/DatagramListener.cpp.o [CXX] ../source/app/config/Config.cpp.o ...

也可以編譯Debug版本，但是要注意，此時前面依賴的函數庫也得編譯成Debug版本，否則運行時會直接崩潰：
