編譯

Mac環境

版本：macOS 10.12express

1.解壓下載的bsdiff-4.3.tar.gzapp

tar -zxvf bsdiff-4.3.tar.gzide

2.進入bsdiff-4.3目錄，在終端下執行構建工具

cd bsdiff-4.3測試

makespa

此時報錯： Makefile:13: *** missing separator. Stop..net

這是makefile文件的內容的格式不對，修改Makefile文件，修改後的文件內容以下：3d

CFLAGS        +=    -O3 -lbz2

PREFIX        ?=    /usr/local
INSTALL_PROGRAM    ?=    ${INSTALL} -c -s -m 555
INSTALL_MAN    ?=    ${INSTALL} -c -m 444

all:        bsdiff bspatch
bsdiff:        bsdiff.c
bspatch:    bspatch.c

install:
    ${INSTALL_PROGRAM} bsdiff bspatch ${PREFIX}/bin
    .ifndef WITHOUT_MAN
    ${INSTALL_MAN} bsdiff.1 bspatch.1 ${PREFIX}/man/man1
    .endif

即.ifndef WITHOUT_MAN，.endi語句f前面加TAB鍵進行縮進

而後再執行make，此時又報錯：

make: *** [bspatch] Error 1

在bspatch.c文件中加入#include <sys/types.h>

而後再執行make命令，此時命令執行成功，會在當前目錄下生成bsdiff,bspatch文件

Ubuntu

版本：15.04

在終端執行sudo apt-get install bsdiff,執行完成後能夠在/usr/bin目錄下找到bsdiff,bspatch文件

OpenSUSE

版本：SUSE 11 SP4

1.解壓下載的bsdiff-4.3.tar.gz

tar -zxvf bsdiff-4.3.tar.gz

2.進入bsdiff-4.3目錄，在終端下執行構建

cd bsdiff-4.3

make

此時報錯： Makefile:13: *** missing separator. Stop.

這是makefile文件的內容的格式不對，修改Makefile文件，修改後的文件內容以下：

CFLAGS        +=    -O3 -lbz2

PREFIX        ?=    /usr/local INSTALL_PROGRAM ?= ${INSTALL} -c -s -m 555 INSTALL_MAN ?= ${INSTALL} -c -m 444 all: bsdiff bspatch bsdiff: bsdiff.c bspatch: bspatch.c install: ${INSTALL_PROGRAM} bsdiff bspatch ${PREFIX}/bin .ifndef WITHOUT_MAN ${INSTALL_MAN} bsdiff.1 bspatch.1 ${PREFIX}/man/man1 .endif

接着編譯,結果報錯,找不到 bzlib.h頭文件，這是因爲bsdiff,bspatch依賴bzip2,下載bzip2,地址：http://www.bzip.org/downloads.html，而後執行如下命令

tar zxvf bzip2-1.0.6.tar.gz

cd bzip2-1.0.6
make
sudo make install

而後再編譯bsdiff,出現如下信息：

修改Makefile, 修改後以下：

CC=gcc
LDFLAGS=
CFLAGS        +=    -O3 -lbz2

PREFIX        ?=    /usr/local
INSTALL_PROGRAM    ?=    cp
INSTALL_MAN    ?=    cp

all:        bsdiff bspatch
bsdiff:        bsdiff.c
    $(CC) bsdiff.c  $(CFLAGS) $(LDFLAGS) -o  bsdiff
bspatch:    bspatch.c
    $(CC) bspatch.c  $(CFLAGS) $(LDFLAGS) -o  bspatch
install:
    ${INSTALL_PROGRAM} bsdiff bspatch ${PREFIX}/bin
    ${INSTALL_MAN} bsdiff.1 bspatch.1 ${PREFIX}/man/man1
