C 从1988年开始编写程序

我试图从1988年开始编译一个程序。这个程序从计算机断层扫描类型的实验中计算二维重建——只考虑光的一级衍射。 我在那里上传了档案：

它包含三个文件夹：

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

Src

和

Lib

都包含一个

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

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

make: *** [david] Error 1

[编辑] 根据alexandernst的建议，我在Makefile中安装了nescc，并将ncc替换为nescc

文件

libui

位于

Lib

中。当我试图编译时：

/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] 正如埃弗特所建议的那样，我将

Lib/diffract.h

符号链接到

Src/diffract.h

，编译过程进一步进行

当我现在尝试编译时，我得到：

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

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

我跑了（我不知道那是怎么回事）

什么也没有归还。当我重命名

Lib/libuis

并尝试编译它时，我得到以下结果：

make: *** [libuis] Error 1

我假设我必须在我的机器上编译libui，才能工作？ 干杯，Paul

为了消除大多数“内置函数的冲突类型”警告，添加了

#include <stdlib.h>`

这将使查找实际错误更加容易

有些错误您必须手动修复。例如，

picout.c

尝试使用

fwrite

，就好像它是

fprintf

，这让我怀疑这段代码是否有效：

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

UnWrap.c

文件使用了一个名为

maging

的符号常量，该常量在任何地方都没有定义。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

---

还有一些地方调用了abort（1），这是一个错误，因为abort函数不带任何参数。在这些情况下，只需删除

1

。除此之外，代码似乎是在GCC上编译的。

而/Src中的diffract.h是空的。

ncc

就是它试图编译的东西-在Makefile中找到包含

ncc

的行，并将其更改为类似于

GCC

的东西，您可能已经安装了它。Lib文件夹中有

libuis

，这是编译后的代码Lib源代码的输出。将该文件作为

libuis.a

（so

cp../Lib/libuis./libuis.a

）复制到Src文件夹中，然后再次运行make。通过修改

Makefile

以使用gcc，您现在会收到一大堆c错误消息。这至少是一种进步。不要用gcc取代ncc！您正在寻找或者可能正在寻找那个时代的Norcroft C编译器。可能很难得到。谢谢，一切都是用gcc编译的。
