Question

我正在尝试从1988年编译一个程序。该程序计算来自计算机断层扫描型实验的二维重建 - 只考虑了光的一阶衍射。我在那里上传了档案：

http://ubuntuone.com/1LXF5SBtUToJZ2lSgGJS47

它包含三个文件夹：

Lib  - libraries
Man  - manuals on the programs
Src  - the actual source scripts

Src和Lib都包含Makefile。当我尝试编译时，我得到：

/Src$ make
ncc david.c -g  -o david libuis.a -lm 
make: ncc: Command not found
make: *** [david] Error 127

[编辑] 正如alexandernst所建议的，我安装了 nescc ，并在Makefile中用nescc替换了ncc。

文件libuis位于Lib。当我尝试编译时：

/Lib$ make
make: `libuis' is up to date.

[编辑] 根据greghnz的建议，我将Lib/libuis复制到Src/libuis.a。

[编辑] 正如Evert所建议的那样，我将Lib/diffract.h符号链接到Src/diffract.h，编译进一步发展。

当我现在尝试编译时，我得到：

nescc david.c -g  -o david libuis.a -lm

我跑了（我不知道那是什么）

ranlib libuis.a

并没有返回任何内容。当我重命名Lib/libuis并尝试编译它时，我得到了这个：

我认为我必须在我的机器上编译 libuis 才能使用它？干杯，保罗

要摆脱大多数“内置函数的冲突类型”警告添加

#include <stdlib.h>`

到diffract.h并将-std=c89添加到Makefile中的CFLAGS。为了让Src中的东西能够在Lib中使用diffract.h，你可以使用符号链接;另一个选择是将-I../Lib添加到CFLAGS：

CFLAGS=-g -std=c89 -I../Lib

这样可以更容易地找到实际错误。

您需要手动修复一些错误。例如，picout.c尝试使用fwrite，就好像它是fprintf一样，这让我想知道这段代码是否有效：

/* was: fwrite(stderr,"Error in writing picture.\n"); */
fprintf(stderr,"Error in writing picture.\n");

UnWrap.c文件使用名为HUGE的符号常量，该常量未在任何位置定义。在RCS目录下的文件中，您可以找到此声明，您可以将其添加到diffract.h：

#define HUGE    1.701411733192644270e38

同样在一些地方有调用abort(1)，这是一个错误，因为中止函数不带参数。在这些情况下，只需删除1即可。除此之外，代码似乎在GCC上编译。
