gcc 4.8.5

Question

我试着在红帽6下编译gcc 4.8.5。这是我的程序：

tar -xvzf archive.tar.gz

cd gcc-4.8.5

./configure --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release \
--with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object \
--enable-languages=fortran,c --prefix=/opt/gcc4.8.5

make

然后，我得到以下错误：

make  all-am
make[4]: Entering directory `/app/gfortran_build/gcc-4.8.5/host-x86_64-unknown-linux-gnu/lto-plugin'
/bin/sh ./libtool --tag=CC --tag=disable-static  --mode=link gcc -Wall -g  -module -bindir /opt/gcc4.8.5/libexec/gcc/x86_64-unknown-linux-gnu/4.8.5   -o

/usr/bin/ld: final link failed: Bad value

我已经读过关于CFLAGS的文章了，但是我不会让它开始工作。

亲切问候

它与以下方面合作：

../gcc-4.8.5/configure CC="/opt/gcc4.5/bin/gcc" --prefix=/opt/gcc4.8.5 --enable-languages=c,c++,fortran --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object

有趣的是CC=..。

安装的gcc版本为4.4.使用此版本，编译将失败。
