Question

我正在使用msys构建适用于Windows 10的GCC 8.3.0，并且构建失败并出现以下错误：

gcc -c -DHAVE_CONFIG_H -g  -I. -I../../source/libiberty/../include  -W -Wall -Wwrite-strings -Wc++-compat -Wstrict-prototypes -Wshadow=local -pedantic  -D_GNU_SOURCE ../../source/libiberty/pex-win32.c -o pex-win32.o

                    ^~~~~~~~~~~~~~~~

c:\software-development\prebuilt\mingw32\include\alloca.h:62:48: note: called from here
 __CRT_ALIAS void *alloca( size_t __n ){ return __builtin_alloca( __n ); }

是否有一种明智的方法来解决配置中的错误，或解决此问题的某种方法来修补或解决此问题？

这是我当前的配置，从批处理文件运行：

--prefix=/c/software-development/gcc-8.3.0/install-x86_64-w64-mingw32 \
--build=x86_64-w64-mingw32 \
--enable-shared \
--enable-static \
--enable-bootstrap \
--enable-languages=c,c++,lto

构建gcc 8.2.0并猜测构建时发生了相同的错误。我正在使用GNU的MinGW 8.2.0进行构建。

尝试在“ C_alloca”上的libiberty.h文件“ __builtin_alloca”中的所有位置进行交换。一处更换。在预处理程序命令中。它帮助了我。
