使用Autoconf对ARM进行交叉编译 [英] Cross-compiling for ARM with Autoconf

问题描述

我无法使用autconf为我的手臂交叉编译库.

I am having trouble cross-compiling a library for my arm board using autconf.

我正在使用此行:

./configure --target=arm-linux --host=arm-linux --prefix=/bla/bla/bla/linux_arm_tool CFLAGS='-m32'
make
make install

当我执行file进行检查时，我得到:

When I do file to check it I get:

libjpeg.so.8.4.0: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped

这似乎根本不对，但是我还是尝试使用它……我得到了:

That doesn't seem right at all, but I tried using it anyway... and I get:

/usr/lib/gcc/arm-linux-gnueabi/4.5.3/../../../../arm-linux-gnueabi/bin/ld: skipping incompatible /bla/bla/bla/bla/../linux_arm_tool/lib/libjpeg.so when searching for -ljpeg

我很茫然，我已经谷歌搜索了一个小时...

I'm at a loss, I've been googling for an hour now...

推荐答案

因此，我知道在使用真正的基本方法调用之前已经进行了交叉编译，并且在检查了输出之后，我弄清楚了为什么不使用它:

So I knew I've cross compiled before using really basic method calls and I figured out why I've gotten away with this before after examining the output:

checking for arm-linux-gnueabi-gcc... no
checking for gcc... gcc
...
...
checking for arm-linux-gnueabi-gcc... gcc

在我的/usr/bin中没有arm-linux-gnueabi-gcc，我必须:

In my /usr/bin there was no arm-linux-gnueabi-gcc, I had to:

ln -s /usr/bin/arm-linux-gnueabi-gcc-4.5 /usr/bin/arm-linux-gnueabi-gcc

---

我成功使用以下命令进行了交叉编译:

---

I successfully cross-compiled using:

./configure --host=arm-linux-gnueabi -prefix=${CSTOOL_DIR}/linux_arm_tool

关于链接...我仍然必须检查一些事情，但是我要假设我可能需要在更高级的编译器中抛出一些-rpath-link标志.

as for linking ... I still have to check some things, but I am going to assume I might need to throw some -rpath-link flags in more advanced compiles.
