linux64下安装swftools

2022-12-02 23:04:36

在文档转换器中，需要在linux上安装swftools，经历了一番曲折过程终于安装成功。swftools安装包从http://www.swftools.org/download.html上面下载。

在./configure过程中会提示需要依赖包freetype和jpegsrc，这两个依赖包可以从官网上下载，也可以从swftools上下载http://download.savannah.gnu.org/releases/freetype/和http://www.ijg.org/files/上下载。

安装freetype-2.5.3.tar.gz

       tar -xzvf freetype-2.5.3.tar.gz

       cd freetype-2.5.3

       ./configure

       make

       make install

安装jpegsrc.v9a.tar.gz

       tar -xzvf jpegsrc.v9a.tar.gz

       cd jpeg-9a

       ./configure

       make

       make install

安装swftools

解压并执行

      tar -xzvf swftools-2013-04-09-1007.tar.gz

      cd swftools-2013-04-09-1007

      ldconfig  /usr/local/lib

提示错误ldconfig: /lib64/libz.so.1 is not a symbolic link，解决方法是

      cd /lib64/

      ls -al

看到libz.so.1不是一个连接而是一个文件

      rm -rf libz.so.1

      ln -s /lib64/libz.so.1.2.8 /lib64/libz.so.1

继续执行

      ./configure --prefix=/usr/local/swftools

      make

在编译jpeg.c时出错，见图

源代码错误，提示swftools-2013-04-09-1007/lib/jpeg.c没有定义常量TRUE，检查并修改jpeg.c文件，添加以下内容

  #include "types.h"

屏蔽365行的typedef unsigned char U8后，重新编译swftools

另外几种错误

gif2swf.c: In function ‘MovieAddFrame’:

gif2swf.c:233: error: too few arguments to function ‘DGifOpenFileName’

gif2swf.c:239: warning: implicit declaration of function ‘PrintGifError’

gif2swf.c:458: error: too few arguments to function ‘DGifCloseFile’

gif2swf.c: In function ‘CheckInputFile’:

gif2swf.c:491: error: too few arguments to function ‘DGifOpenFileName’

gif2swf.c:521: error: too few arguments to function ‘DGifCloseFile’

make[1]: *** [gif2swf.o] Error 1

make[1]: Leaving directory `/home/pjroot/swftools-2013-04-09-1007/src'

make: *** [all] Error 2

错误原因：
由于giflib 5.1的DGifOpenFileName函数和DGifCloseFile函数参数签名发生变化，而gif2swf.c中调用仍然使用旧有版本导致参数不匹配
DGifOpenFileName变化

GifFileType *DGifOpenFileName(char *GifFileName)//old

GifFileType *DGifOpenFileName(char *GifFileName, int *ErrorCode) //new

DGifCloseFile变化

int DGifCloseFile(GifFileType *GifFile) // old

int DGifCloseFile(GifFileType *GifFile, int *ErrorCode) //new

解决方法：
        gif2swf.c 中几处做修改
        233和491行
        if ((gft = DGifOpenFileName(sname)) == NULL) {
        改为
       if ((gft = DGifOpenFileName(sname, 0)) == NULL) {

458和512行
DGifCloseFile(gft);改为 DGifCloseFile(gft, NULL);

错误原因：
没有连接到库，执行以下命令

    ldconfig /usr/local/lib

再次重新configure并make安装

   ./configure --prefix=/usr/local/swftools

   make

   make install

   make clean

   make distclean
