在cygwin下的Windows7-64上编译gcc时出现以下错误.
./../zlib/libz.a(libz_a-gzlib.o):gzlib.c:(.text+0x646): undefined reference to `_wopen'
./../zlib/libz.a(libz_a-gzlib.o):gzlib.c:(.text+0x646): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `_wopen'
collect2: error: ld returned 1 exit status
make[3]: *** [../.././gcc/fortran/Make-lang.in:97: f951.exe] Error 1
什么是wopen？
gcc-6或gcc-5不会发生这种情况.
谢谢.
