c - 'c interfaces and implementations' (David Hanson) 代码安装

Question

我正在尝试安装本书附带的代码:https://sites.google.com/site/cinterfacesimplementations/

按照作者在此处给出的说明进行操作:http://cii.googlecode.com/svn/trunk/install.html

我的电脑在 32 位 i686 架构上安装了 ubuntu 11.04。按照作者对我尝试的 32 位 linux 的说明进行操作:

make CC='cc -DMAXALIGN=4' AS='cc -c -x assembler-with-cpp -traditional'

其中cc是gcc版本4.5.2其中给出了以下警告和错误:

makefile:138: warning: overriding commands for target `maxalign'
makefile:135: warning: ignoring old    cc -DMAXALIGN=4 -g -Iinclude -c -o ap.o src/ap.c

In file included from src/thread.c:100:0:

src/thread.c:108:2: warning: ‘sigsetmask’ is deprecated (declared at /usr/include/signal.h:199)
make: *** [thread.o] Error 1

不确定在这里做什么。同样令人费解的是/usr/include/i386-linux-gnu。因为如果我这样做

uname -m

它打印 i686 而不是 i363。有什么想法吗？

干杯，吉姆

在 thread.c 的第 100 行——删除 #include <asm/sigcontext.h> (或将其注释掉)。那应该删除“重复声明”。它不会修复不推荐使用的接口(interface)的使用(十年前写的书和 5 年前更新的代码的问题)，如果您尝试在 64 位处理器上运行它，则会出现其他我没有尝试修复的问题.
