我正在尝试在运行 Linux 2.6.31.8 armv5tel的Buffalo LinkStation Pro Duo(解锁后)上编译 GCC 4.7.2。
不幸的是,make
抛出相当多的错误,从
gcc -c -DIN_GCC_FRONTEND -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-formIn file included from ../../gcc-4.7.2/gcc/tree.h:32,

real.h
reads的第 53 行unsigned long sig[SIGSZ];
,其中SIGSZ
在第 40 行定义为,
#define SIGSZ (SIGNIFICAND_BITS / HOST_BITS_PER_LONG)
而第 87行从第 72 行开始定义#if REAL_WIDTH == 1
为REAL_WIDTH
#define REAL_WIDTH \
(REAL_VALUE_TYPE_SIZE/HOST_BITS_PER_WIDE_INT \
+ (REAL_VALUE_TYPE_SIZE%HOST_BITS_PER_WIDE_INT ? 1 : 0)) /* round up */
这似乎归结为HOST_BITS_PER_*
为零。我是否必须使用某些configure
参数手动定义这些,或者如何解决此问题?
更新
config.log
包含以下错误:
