Question

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

按照作者在此处发出的指示：http://cii.googlecode.com/svn/trunk/install.html

我的电脑在32位i686架构上有ubuntu 11.04。按照作者对32位linux的说明我尝试：

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

其中cc是gcc版本4.5.2 这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

不知道该怎么做。令人费解的是/ usr / include / i386-linux-gnu。因为我做了

uname -m

打印i686而不是i363。任何人的想法？

干杯，吉姆

在thread.c中的第100行 - 删除#include <asm/sigcontext.h>（或将其注释掉）。那应该删除“重复声明”。它不会修复已弃用接口的使用（十年前编写的书籍问题以及5年前更新的代码），如果您尝试在64位处理器上运行此问题，则会出现其他问题我还没有尝试修复。
