Q. How to cross compile valgrind for ARM on x86 ubuntu machine ?
Here is a self-contained procedure, assuming you are building on a x86_64 Ubuntu Linux machine. If this is not the case, just install the cross-compiler for the arm-none-linux-gnueabihf target available from your Linux distribution, make sure it is in your path, and modify the configure command accordingly.
On the PC side:
# downloading/installing toolchain
wget https://developer.arm.com/-/media/Files/downloads/gnu-a/10.2-2020.11/binrel/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf.tar.xz?revision=d0b90559-3960-4e4b-9297-7ddbc3e52783&la=en&hash=985078B758BC782BC338DB947347107FBCF8EF6B
sudo mkdir -p /opt/arm/10
sudo tar Jxf gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf.tar.xz -C /opt/arm/10
# downloading/extracting valgrind
wget https://sourceware.org/pub/valgrind/valgrind-3.16.1.tar.bz2
tar jxf valgrind-3.16.1.tar.bz2
# building
export PATH=/opt/arm/10/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf/bin:$PATH
mdkir valgrind
cd valgrind
../valgrind-3.16.1/configure --host=arm-none-linux-gnueabihf --prefix=$(pwd)/valgrind-3.16.1-arm-none-linux-gnueabihf
make all install
On the Orangepi:
Copy the content of the valgrind-3.16.1-arm-none-linux-gnueabihf directory and its sub-directories from your PC into the /usr/local directory of your Orangepi.
Install libc6-dbg (assuming you are running Ubuntu or Debian on your Orangepi): apt-get install libc6-dbg
test using the procedure provide here:
wget http://cs.ecs.baylor.edu/~donahoo/tools/valgrind/test.c
gcc -o test -g test.c
