我正在尝试binutils在平台 A上构建，它将在平台 A上运行并以平台 B为目标。

我有binutilsin的来源/home/cedric/source/binutils-2.29/，我执行以下 2 个构建：

cd /home/cedric/source/
mkdir default/ && cd default/
mkdir build/ install/ & cd build/
../../binutils-2.29/configure --prefix=/home/cedric/source/default/install/
make
make install

和

cd /home/cedric/source/
mkdir lfs/ && cd lfs/
mkdir build/ install/ & cd build/
../../binutils-2.29/configure --prefix=/home/cedric/source/lfs/install/ --target=x86_64-lfs-linux-gnu
make
make install

事实证明， indefault/install比 in多了 2 个目录lfs/install，即lib包含静态库的目录和bfd包含一些头文件的目录。opcodesinclude

我的困惑

为什么要安装这些静态库和头文件（它们的用途是什么，因为已经构建了诸如此类的binutils工具）？为什么在为另一个平台构建时它们会消失？ldas

我所做的研究并没有消除我的困惑：

binutils-2.29/configure --helpREADME在binutils-2.29/, binutils-2.29/binutils/,和binutils-2.29/bfd/

FWIW，我在配置帮助中找到了以下内容，这与它可能创建的目录及其默认值有关：

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
              [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
              [PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/PACKAGE]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]
