编译 glibc :/glibc-2. 7/w/elf/ld.so: 没有那个文件或目录

Question

我要在超算中心的目录下安装一个软件，但是sudo，root，连apt-get，yum都不能用...这个软件需要glibc2.7，所以我得手动安装gcc和glibc(因为我无法更改内置 gcc 的路径来查找 glibc)。

gcc 似乎安装成功:

[geosign@node117 ~/binutils/bin]$ gcc -v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: /public/home/geosign/software/gcc/configure -prefix=/public/home/geosign/gcc --with-gmp=/public/home/geosign/Gcc --with-   mpfr=/public/home/geosign/Gcc --with-mpc=/public/home/geosign/Gcc --with-ppl=/public/home/geosign/ppl --with-cloog=/public/home/geosign/ppl --enable-threads=posix CFLAGS=-I/public/home/geosign/ppl/lib:/public/home/geosign/Gcc/lib CPPFLAGS=-I/public/home/geosign/ppl/lib:/public/home/geosign/Gcc/lib CXXFLAGS=-I/public/home/geosign/ppl/lib:/public/home/geosign/Gcc/lib --enable-languages=c,c++,fortran --disable-multilib

线程模型:posix gcc 版本 4.4.7 (GCC)

但是，当我使用“make”编译glibc时，它显示:

elf的Makefile中的这几句是:

    @rm -f $@.lds
    $(LINK.o) -nostdlib -nostartfiles -shared $(z-now-$(bind-now))  \

          > $@.lds
    $(LINK.o) -nostdlib -nostartfiles -shared -o $@         \
          $(LDFLAGS-rtld) -Wl,-z,defs $(z-now-$(bind-now))  \
          $(filter-out $(map-file),$^) $(load-map-file)     \
          -Wl,-soname=$(rtld-installed-name) -T $@.lds
    rm -f $@.lds
    readelf -s $@ \
      | awk '($$7 ~ /^UND(|EF)$$/ && $$1 != "0:" && $$4 != "REGISTER") { print; p=1 } END { exit p != 0 }'

这是我配置 glibc 的方式:

/public/home/geosign/software/glibc/configure --prefix=/public/home/geosign/glibc  --with-binutils=/public/home/geosign/binutils/ --enable-shared --disable-multilib

ldd ld 显示:

[geosign@node117 ~/binutils/bin]$ ldd ld
    linux-vdso.so.1 =>  (0x00007fff163be000)
    libz.so.1 => /lib64/libz.so.1 (0x0000003fd1400000)
    libc.so.6 => /lib64/libc.so.6 (0x0000003fd0400000)
    /lib64/ld-linux-x86-64.so.2 (0x0000003fd0000000)

非常感谢。我的时间真的很有限，我花了很多天时间。

你的直接问题是:

gcc   -nostdlib -nostartfiles -shared -o -mcmodel=large \
  /public/home/geosign/software/glibc-2.7/w/elf/ld.so ...

这告诉 GCC 创建一个名为 -mcmodel=large 的输出文件，而不是预期的输出文件 /public/home/geosign/software/glibc-2.7/w/elf/ld .so.

你没有告诉我们你是如何配置这个 GLIBC 构建的，但我怀疑你在 ./configure 调用的某处使用了 -mcmodel=large 。不要那样做，没有理由在构建 glibc 时使用 -mcmodel=large。
