错误：为 centos7 构建 GCC 14.2 时出现未知类型名称“max_align_t”

Question

我正在从centos7的源代码构建

gcc 14.2.0

，并在

gettext

过程中遇到了以下问题。我计划使用

make

附带的最新 C++ 编译器。gcc 14

我的

gcc -std=gnu99 -DHAVE_CONFIG_H -DEXEEXT=\"\" -I. -I../../../gcc-14.2.0/gettext/gettext-runtime/gnulib-lib -I..  -I../intl -I../../../gcc-14.2.0/gettext/gettext-runtime/intl -DDEPENDS_ON_LIBICONV=1 -DDEPENDS_ON_LIBINTL=1   -Wno-cast-qual -Wno-conversion -Wno-float-equal -Wno-sign-compare -Wno-undef -Wno-unused-function -Wno-unused-parameter -Wno-pedantic -Wno-sign-conversion -Wno-type-limits -Wno-unsuffixed-float-constants -g -c -o unistr/libgrt_a-u8-uctomb.o `test -f 'unistr/u8-uctomb.c' || echo '../../../gcc-14.2.0/gettext/gettext-runtime/gnulib-lib/'`unistr/u8-uctomb.c

   union { max_align_t __align; char __c[1024]; } __space;
         ^

版本是

gettext

这就是我尝试构建它的方式

# gettext --version

有人可以帮我安装吗

yum groupinstall -y "Development Tools"
yum install -y wget bzip2 tar

GCC_VERSION=14.2.0
wget https://ftp.gnu.org/gnu/gcc/gcc-$GCC_VERSION/gcc-$GCC_VERSION.tar.gz
tar -xvzf gcc-$GCC_VERSION.tar.gz
cd gcc-$GCC_VERSION

./contrib/download_prerequisites
mkdir ../gcc-build
cd ../gcc-build
../gcc-$GCC_VERSION/configure --enable-languages=c,c++ --disable-multilib

make -j$(nproc)
make install

？有什么办法可以解决这个问题吗？
