自动工具eclipse插件中的MALLOC选项



我正在为Eclipse中的自动工具插件和我下载的一些C++项目而苦苦挣扎。

我的目标是为arm处理器进行交叉编译,因此该项目已经配置为使用自动工具,但当我尝试交叉编译时,我遇到了以下问题

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,注意到这个

...
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 

但不是通过Eclipse或autotools插件,因为项目的设置不可用。你能启发我吗?

问候,

提前感谢

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:

我已经尝试过ldav1s建议使用以下配置

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"  

我收到这些错误

编辑2在重新安装eclipse之后,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

它编译得很好,我看到了一些arm/le输出,但我遇到了这个错误关于其中一个图书馆

您还没有将C++编译器(CXX)设置为configure的参数的一部分,也没有对C编译器(CC)进行乘法定义。

您似乎在为构建机器(/usr/include中的编译器)而不是为交叉编译器(/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1中的编译器。
