编译 gcc 4.8.5

Compiling gcc 4.8.5

我正在尝试在 Red Hat 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
collect2: ld returned 1 exit status

我已经阅读了有关 CFLAGS 的内容,但我无法让它发挥作用。

亲切的问候

GCC 已记录需要在其源代码树外部构建;请参阅 configuring chapter of its installation 文档:

First, we highly recommend that GCC be built into a separate directory from the sources which does not reside within the source tree. This is how we generally build GCC; building where srcdir == objdir should still work, but doesn’t get extensive testing; building where objdir is a subdirectory of srcdir is unsupported.

因此您需要根据该规则构建它。因此你的 GCC 构建:

cd gcc-4.8.5
#wrong code from the original question! Don't use that
./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

错误;我至少会推荐:

  cd gcc-4.8.5
  mkdir ../_BuildGCC
  cd ../_BuildGCC
  ../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/gnu \
      --program-suffix=-mine

然后,在整个构建之后,可能与

 make -j4

之后是一些 mkdir /opt/gnu 具有适当用户和许可的人,然后(在同一个 _BuildGCC 中)

make install DESTDIR=/tmp/gccinst

,最后 cp -vr /tmp/gccinst/opt/gnu /opt/gnu 成为 运行 适当的(可能是 root....,也许 cp -va

然后您将 /opt/gnu/bin/ 添加到您的 PATH variable,然后您将使用 gcc-mine 来编译您的代码。

顺便说一句,GCC 与 C 程序兼容,因为 ABI don't change. And GCC 4.8 is obsolete and unsupported. You'll better compile from source the supported versions (listed on gcc.gnu.org; in January 2018, GCC 7.2 & GCC 6.4)

也许您的特定 Redhat 系统需要 additional/specific CFLAGS 附加 到您的 configure 命令中。您可以询问您的 Redhat 支持,或者尝试在 ../gcc-4.8.5/configure 命令的末尾附加 CFLAGS=-fPIECFLAGS=-fPIC

最后,您可能会在 gcc-help@gcc.gnu.org 上获得此类帮助,但您最好尝试使用最新的 GCC。很少有 GCC 成员记得 4.8 ....

如果您确实确切地 GCC 4.8(但我对此表示怀疑),如果需要,您可以购买昂贵的支持(例如来自 RedHat 或 AdaCore 的人)。

Google 我发现 Installing gcc 4.8 and Linuxbrew on CentOS 6

它适用于以下各项:

../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

有趣的部分是 CC=...

安装的gcc版本是4.4。使用此版本,编译失败。
