Install gflags. You may download it from here: # https://code.google.com/p/gflags/ # 2. Once install, add the include path/lib path for gflags to CPATH and # LIBRARY_PATH respectively. If installed with default mode, the # lib and include path will be /usr/local/lib and /usr/local/include # Mac user can do this by running build_tools/mac-install-gflags.sh OUTPUT=$1 if test -z "$OUTPUT"; then echo "usage: $0 <output-filename>" >&2 exit 1 fi # we depend on C++11 PLATFORM_CXXFLAGS="-std=c++11" # we currently depend on POSIX platform COMMON_FLAGS="-DROCKSDB_PLATFORM_POSIX" # Default to fbcode gcc on internal fb machines if [ -z "$ROCKSDB_NO_FBCODE" -a -d /mnt/gvfs/third-party ]; then FBCODE_BUILD="true" source "$PWD/build_tools/fbcode_config.sh" fi # Delete existing output, if it exists rm -f "$OUTPUT" touch "$OUTPUT" if test -z "$CC"; then CC=cc fi if test -z "$CXX"; then CXX=g++ fi # Detect OS if test -z "$TARGET_OS"; then TARGET_OS=`uname -s` fi COMMON_FLAGS="$COMMON_FLAGS ${CFLAGS}" CROSS_COMPILE= PLATFORM_CCFLAGS= PLATFORM_CXXFLAGS="$PLATFORM_CXXFLAGS ${CXXFLAGS}" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS" PLATFORM_SHARED_EXT="so" PLATFORM_SHARED_LDFLAGS="-shared -Wl,-soname -Wl," PLATFORM_SHARED_CFLAGS="-fPIC" PLATFORM_SHARED_VERSIONED=false # generic port files (working on all platform by #ifdef) go directly in /port GENERIC_PORT_FILES=`cd "$ROCKSDB_ROOT"; find port -name '*.cc' | tr "\n" " "` # On GCC, we pick libc's memcmp over GCC's memcmp via -fno-builtin-memcmp case "$TARGET_OS" in Darwin) PLATFORM=OS_MACOSX COMMON_FLAGS="$COMMON_FLAGS -DOS_MACOSX" PLATFORM_SHARED_EXT=dylib PLATFORM_SHARED_LDFLAGS="-dynamiclib -install_name " # PORT_FILES=port/darwin/darwin_specific.cc ;; IOS) PLATFORM=IOS COMMON_FLAGS="$COMMON_FLAGS -DOS_MACOSX -DIOS_CROSS_COMPILE -DROCKSDB_LITE" PLATFORM_SHARED_EXT=dylib PLATFORM_SHARED_LDFLAGS="-dynamiclib -install_name " CROSS_COMPILE=true ;; Linux) PLATFORM=OS_LINUX COMMON_FLAGS="$COMMON_FLAGS -DOS_LINUX" if [ -z "$USE_CLANG" ]; then COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp" fi PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS -lpthread -lrt" # PORT_FILES=port/linux/linux_specific.cc ;; SunOS) PLATFORM=OS_SOLARIS COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp -D_REENTRANT -DOS_SOLARIS" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS -lpthread -lrt" # PORT_FILES=port/sunos/sunos_specific.cc ;; FreeBSD) PLATFORM=OS_FREEBSD COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp -D_REENTRANT -DOS_FREEBSD" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS -lpthread" # PORT_FILES=port/freebsd/freebsd_specific.cc ;; NetBSD) PLATFORM=OS_NETBSD COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp -D_REENTRANT -DOS_NETBSD" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS -lpthread -lgcc_s" # PORT_FILES=port/netbsd/netbsd_specific.cc ;; OpenBSD) PLATFORM=OS_OPENBSD COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp -D_REENTRANT -DOS_OPENBSD" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS -pthread" # PORT_FILES=port/openbsd/openbsd_specific.cc ;; DragonFly) PLATFORM=OS_DRAGONFLYBSD COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp -D_REENTRANT -DOS_DRAGONFLYBSD" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS -lpthread" # PORT_FILES=port/dragonfly/dragonfly_specific.cc ;; OS_ANDROID_CROSSCOMPILE) PLATFORM=OS_ANDROID COMMON_FLAGS="$COMMON_FLAGS -fno-builtin-memcmp -D_REENTRANT -DOS_ANDROID -DLEVELDB_PLATFORM_POSIX" PLATFORM_LDFLAGS="$PLATFORM_LDFLAGS " # All pthread features are in the Android C library # PORT_FILES=port/android/android.cc CROSS_COMPILE=true ;; *) echo "Unknown platform!" >&2 exit 1 esac JAVA_LDFLAGS="$PLATFORM_LDFLAGS" if test -z "$DO_NOT_RUN_BUILD_DETECT_VERSION"; then "$PWD/build_tools/build_detect_version" fi # We want to make a list of all cc files within util, db, table, and helpers # except for the test and benchmark files.
