在Ubuntu 14.04中编译GCC 3.4.6时出错 [英] Error compiling GCC 3.4.6 in Ubuntu 14.04

问题描述

我试图在Ubuntu 14.04 x64中编译GCC 3.4.6。它已经有GCC-4.8.2的新版本。

我运行了 ./ configure --prefix = / usr / local / gcc-3.4 和 make 。

我最终遇到了几个错误，我可以在这些错误中找到解决方案。

错误1

错误2

  ../../最后，我终于遇到了这个错误，我找不到任何解决方案。 gcc / unwind-dw2.c：函数`uw_frame_state_for'：
 ../../gcc/unwind-dw2.c:1031：error：field`info'有不完整的类型
 make [2 ]：*** [libgcc / 32 / unwind-dw2.o]错误1 
 make [2]：离开目录`/home/hp-11/Documents/gcc-3.4.6/build/gcc'
 make [1]：*** [stmp-multilib]错误2 
 make [1]：离开目录`/home/hp-11/Documents/gcc-3.4.6/build/gcc'
 make：*** [all-gcc] Error 2 
  

有人知道如何解决它？请告诉我是否需要更多细节。

这是一个老知名的问题，关于siginfo和siginfo_t

所有你需要的就是看你所有地方的GCC资源，比如

  struct rt_sigframe {\ 
 int sig; \ 
 struct siginfo * pinfo; \ 
 void * puc; \ 
 struct siginfo info; \ 
 struct ucontext uc; \ 
} * rt_ =（CONTEXT） - > cfa; \ 
 sc_ =（struct sigcontext *）& rt _-> uc.uc_mcontext; \ 
  

这个是在gcc / config / i386 / linux.h里面的， / p>

手动将 struct siginfo * 替换为 siginfo_t * 和 struct siginfo 到 siginfo_t ，使它成为最新的POSIX兼容。在每个rt_sigframe声明中，最常见的是两个这样的地方，包括您的 info 问题字段。

I am trying to compile GCC 3.4.6 in Ubuntu 14.04 x64. It already has newer version of GCC-4.8.2.

I ran ./configure --prefix=/usr/local/gcc-3.4 and make.

I ended up in several errors for which I could find solutions on searching.

Error 1

Error 2

Finally I ended up in this error, which I couldn't find any solution.

../../gcc/unwind-dw2.c: In function `uw_frame_state_for':
../../gcc/unwind-dw2.c:1031: error: field `info' has incomplete type
make[2]: *** [libgcc/32/unwind-dw2.o] Error 1
make[2]: Leaving directory `/home/hp-11/Documents/gcc-3.4.6/build/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/home/hp-11/Documents/gcc-3.4.6/build/gcc'
make: *** [all-gcc] Error 2

Does anybody know how to fix it? Please let me know if more details are needed.

解决方案

This is old good-known problem, regarding siginfo and siginfo_t

All you need is to look at you GCC sources for all places like

struct rt_sigframe {            \
  int sig;              \
  struct siginfo *pinfo;          \
  void *puc;              \
  struct siginfo info;            \
  struct ucontext uc;           \
} *rt_ = (CONTEXT)->cfa;          \
sc_ = (struct sigcontext *) &rt_->uc.uc_mcontext;   \

this one is inside gcc/config/i386/linux.h but your arch may differ

And manually replace struct siginfo * to siginfo_t * and struct siginfo to siginfo_t, making it newest POSIX compatible. In every rt_sigframe declaration there is most common to be two such places, including your info field of problem.
