问题
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.
回答1:
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.
