在How To Build GCC 4.8.2 ARM Cross-Compiler之后，我已成功安装了所有内容。但GMP与GCC的联系并没有在那里完成，我提到了这个tutorial - 如下所示
mkdir $BUILDDIR/gmp
cd $BUILDDIR/gmp
export CFLAGS=-static
../../sources/gmp-4.3.2/configure \
--build=$BUILDMACH \
--host=$TARGETMACH \

You appear to have set $CFLAGS, perhaps you also need to tell GMP the
intended ABI, see "ABI and ISA" in the manual.
如何解决这个问题？我看起来很详尽但是徒劳无功。
谢谢！
答案 0 :(得分：0)
configure：警告：将来，Autoconf不会检测名称不以主机三元组开头的交叉工具。如果您认为此配置对您有用，请写信至autoconf@gnu.org。
这是回顾以前消息的线索，这些消息是：
检查arm-none-linux-gnueabi-strip ...否
检查条带...条带
似乎找不到你的跨binutils。请注意，configure也可能会在普通桌面系统上为名为mt的实用程序发出此警告，但这个实际上并不是问题。未找到指定主机/目标系统的binutils程序的事实通常表明您将无法按照您的意图编译任何内容。
检查编译器arm-none-linux-gnueabi-gcc -static ... no
进一步表明您的PATH中没有交叉工具链，因为它无法找到C交叉编译器。如果您为编译的所有内容运行make install并将安装的bin目录添加到PATH，则应该正确找到这些工具。来自ARM cross-compiler tutorial you linked：
你做完了！ :)现在用你的新玩具编译测试程序，看它是否有效。在 new 终端中运行：
$ export INSTALLDIR=~/workbench/gcc-4.8.2/arm $ export PATH=$INSTALLDIR/bin:$PATH $ export TARGETMACH=arm-none-linux-gnueabi $ export BUILDMACH=i686-pc-linux-gnu $ export CROSS=arm-none-linux-gnueabi $ export CC=${CROSS}-gcc $ export LD=${CROSS}-ld $ export AS=${CROSS}-as
注意INSTALLDIR和PATH的行。另外，确保您可以编译测试程序：
现在编译你的测试程序：
$ $CC -Wall -Wextra <your test>.c -o <your test>检查您的测试程序是否已成功交叉编译为ARM：
$ file <your test> bash: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped如果您看到类似于上面输出的内容，那么您已成功交叉编译了测试程序。
