程序配置为使用dmalloc纾困引用头文件错误

在尝试编译lynx时,我使用了'with-dmalloc'configure选项。但是编译中止了,产生了这个错误:

 /usr/include/dmalloc.h:460: error: expected identifier or '(' before '__extension__'
> /usr/include/dmalloc.h:484: error: expected identifier or '(' before '__extension__'
> make[1]: *** [HTParse.o] Error 1
> make[1]: Leaving directory `/tmp/lynx2-8-8/WWW/Library/Implementation'
> make: *** [all] Error 2

这是dmalloc.h中的错误行:


> Line 460: char *strdup(const char *string);
> Linu 484: char *strndup(const char *string, const DMALLOC_SIZE len);

也可以在http://www.filewatcher.com/p/dmalloc-5.5.2.tbz.467309/include/dmalloc.h.html

查看该文件

dmalloc上的开发已经停止了,所以并不是真的希望从上游修复。有什么帮助吗?

我在Fedora 21 x86_64上安装dmalloc时遇到了类似的问题:

dmalloc-5.5.2]$ make
rm -f dmalloc.h dmalloc.h.t
cat ./dmalloc.h.1 dmalloc.h.2 ./dmalloc.h.3 > dmalloc.h.t
mv dmalloc.h.t dmalloc.h
rm -f arg_check.o
gcc -g -O2  -DHAVE_STDARG_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -    DHAVE_UNISTD_H=1 -DHAVE_SYS_MMAN_H=1 -DHAVE_SYS_TYPES_H=1 -    DHAVE_W32API_WINBASE_H=0 -DHAVE_W32API_WINDEF_H=0 -DHAVE_SYS_CYGWIN_H=0 -    DHAVE_SIGNAL_H=1  -I. -I.  -c arg_check.c -o ./arg_check.o
In file included from /usr/include/string.h:634:0,
             from arg_check.c:33:
dmalloc.h:484:7: error: expected identifier or ‘(’ before ‘__extension__’
 char *strndup(const char *string, const DMALLOC_SIZE len);
   ^
Makefile:362: recipe for target 'arg_check.o' failed
make: *** [arg_check.o] Error 1

通过改变dmalloc-5.5.2 / dmalloc.h.3解决它:

 - 432 | extern
 - 433 | char    *strndup(const char *string, const DMALLOC_SIZE len);

 + 432 | #undef strndup
 + 433 | extern
 + 434 | char    *strndup(const char *string, const DMALLOC_SIZE len);

我遇到过这样的事情,发现这是由dmalloc.h引起的,例如< unistd.h中>等。这样来自dmalloc.h的宏标识符破坏了真正的valloc / realloc / memdup等的声明。

这可能是你所看到的吗?
