交叉为手臂发行libnftnl

如何解决交叉为手臂发行libnftnl

libnftnl对libmnl有依赖性，我为ARM分别交叉编译了libmnl。编译的库和包含目录位于/ home / badri / arm_libs / mnl

./ configure --build = x86_64-pc-linux-gnu --host = aarch64-linux-gnu --enable-static = no --prefix = / home / badri / arm_libs / nftnl LIBMNL_LIBS = / home / badri / arm_libs / mnl / lib LIBMNL_CFLAGS = / home / badri / arm_libs / mnl / include LDFLAGS = -L / home / badri / arm_libs / mnl / lib LIBS = -lmnl --includedir = / home / badri / arm_libs / mnl /包含

此配置成功。而且我可以看到'configure'的输出表明存在LIBMNL。

。

。

检查pkg-config的版本至少为0.9.0 ...是

正在检查LIBMNL ...是

正在检查aarch64-linux-gnu-gcc ...（已缓存）aarch64-linux-gnu-gcc

。

。

但是当我尝试做一个make时，我遇到了这个失败。

configure我缺少什么吗？

./ configure --help

$ ./configure --help
`configure' configures libnftnl 1.1.7 to adapt to many kinds of systems.

Usage: ./configure [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g.,CC,CFLAGS...),specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h,--help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V,--version           display version information and exit
  -q,--quiet,--silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C,--config-cache      alias for `--cache-file=config.cache'
  -n,--no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

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]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --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/libnftnl]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-dependency-tracking
                          do not reject slow dependency extractors
  --disable-dependency-tracking
                          speeds up one-time build
  --enable-silent-rules   less verbose build output (undo: "make V=1")
  --disable-silent-rules  verbose build output (undo: "make V=0")
  --enable-static[=PKGS]  build static libraries [default=no]
  --enable-shared[=PKGS]  build shared libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-pic[=PKGS]       try to use only PIC/non-PIC objects [default=use
                          both]
  --with-aix-soname=aix|svr4|both
                          shared library versioning (aka "SONAME") variant to
                          provide on AIX,[default=aix].
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
                          compiler's sysroot if not specified).

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags,e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker,e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags,e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  PKG_CONFIG  path to pkg-config utility
  PKG_CONFIG_PATH
              directories to add to pkg-config's search path
  PKG_CONFIG_LIBDIR
              path overriding pkg-config's built-in search path
  LIBMNL_CFLAGS
              C compiler flags for LIBMNL,overriding pkg-config
  LIBMNL_LIBS linker flags for LIBMNL,overriding pkg-config
  LT_SYS_LIBRARY_PATH
              User-defined run-time library search path.
  CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

解决方法

创建了一个名为nftnl2的新前缀路径，并尝试了此操作。

./ configure --build = x86_64-pc-linux-gnu --host = aarch64-linux-gnu --enable-static = no --prefix = / home / badri / arm_libs / nftnl2 LIBMNL_LIBS = / home / badri / arm_libs / mnl / lib LIBMNL_CFLAGS = / home / badri / arm_libs / mnl / include /

现在我可以在/ home / badri / arm_libs / nftnl2下看到include和lib。因此，添加这些额外的标志一定会引起一些问题。最终这只是配置问题。
