Valgrind cross compilation for ARMv5tel

问题

I ran configure with the following option:

./configure --target=armv5tel CC=arm-linux-gnueabi-gcc --host=i686-linux

then ran make

I encountered the following error:

Am I missing something?

Your configure arguments are not right for cross-compilation. To cross-compile with recent autoconf you just specify host and let it figure the rest out. So it would be more like this:

./configure --host=arm-linux-gnueabi

I also had to modify the configure script by replacing "armv7*" with "arm*". You'll see where.

However, there's another problem. The ARM support in valgrind covers all ARMv5 instructions and a select subset of v6 and v7 instructions. BUT, and it's a big but, to actually RUN valgrind you must use a CPU capable of running ARMv7 code. That means Cortex-A or better.

If you intend to run valgrind on an ARMv5 class processor (like XScale) it will not work and the target program will fault with an illegal opcode.

Sad but true. No valgrind for me.

HTH.

1. make clean
2. ./configure CC="your path of gcc" --target=arm-none-linux-gnueabi --host=armv7-none-linux-gnueabi
3. make
4. sudo make install
