我正在为 Eclipse 中的 autotools 插件和我下载的一些 C++ 项目而苦苦挣扎。
我的目标包括对 arm 处理器进行交叉编译，因此该项目已经配置为使用 autotools，但是当我尝试交叉编译时出现以下问题
In file included from /usr/include/c++/4.6/bits/stl_algo.h:61:0,
from /usr/include/c++/4.6/algorithm:63,
from dtntracepath.cpp:17:
/usr/include/c++/4.6/cstdlib:119:11: error: ‘::malloc’ has not been declared
我已经检查了我的项目的配置输出并注意到了这一点
...
checking for stdlib.h... (cached) yes
checking for GNU libc compatible malloc... no
checking for memset... yes
...
我知道如何通过添加选项通过 linux 终端修复它
export ac_cv_func_malloc_0_nonnull=yes
但不能通过 Eclipse 或 autotools 插件，因为项目的设置不可用。你能启发我吗？
亲切的问候，
提前致谢
PS：我在 autotools 插件中设置的参数如下：
-Command: configure CFLAGS="-m32" LDFLAGS="-m32" CC=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-gcc CC=c99
-All options : --host=arm-mv5sft-linux-gnueabi --build=i686-linux --target=arm-mv5sft-linux-gnueabi --with-sysroot=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/arm-mv5sft-linux-gnueabi/
编辑：
我已经使用以下配置尝试了 ldav1s 建议
configure CC=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-gcc CXX=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-g++ CFLAGS="-m32" LDFLAGS="-m32"
我收到这些错误

EDIT2 重新安装eclipse后，第一版的++错误消失了，现在如果我使用以下配置
configure CC=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-gcc CXX=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-g++ CFLAGS="-m32" LDFLAGS="-m32"--host=arm-mv5sft-linux-gnueabi --build=i686-linux --target=arm-mv5sft-linux-gnueabi
它正在正确编译，我看到了一些 arm/le 输出，但是我收到了与其中一个库有关的错误
