This program is heavely inspired by https://github.com/benthepoet/c-sexpr-parser/ and rework some logic to fit our needs and add a nested fashion printing option.
The dataset used for the unit test is stored in the dataset/exemple.sexp path.
To build the program please use the Makefile provided by invoking the make command:
makeThe Makefile support the cross-compilation, to build the program for an other architecture please fill the $CROSS_COMPILATION environment variable with the prefix of your toolchain (e.g: arm-linux-gnueabihf- only, if you are using the arm-linux-gnueabihf GCC, LD, etc.
Your toolchain should be available in your $PATH:
CROSS_COMPILATION=arm-linux-gnueabihf- && makeThis program comes with some options, please at least use the -p for printing or -t for testing the dataset respectively:
./sexpr -h Usage : sexpr [options] Options: -h print this help message -p print the output of the sexpression dataset in a nested fashion format -t run test on the dataset, only work with the default dataset (exemple.sexp) -d specify the dataset path to use
First you need to install qemu-arm, it depends on your Linux distribution.
Then download an arm toolchain, i'm using the bootlin toolchain for armv6 available here: https://toolchains.bootlin.com/downloads/releases/toolchains/armv6-eabihf/tarballs/armv6-eabihf--glibc--stable-2020.08-1.tar.bz2
Extract the toolchain, then before compiling the project, do the following:
ARCH=arm
PATH=/path_to_your_extracted_toolchain/armv6-eabihf--glibc--stable-2020.08-1/bin/:$PATH
CROSS_COMPILE=arm-linux-
LD_LIBRARY_PATH=/path_to_your_extracted_toolchain/armv6-eabihf--glibc--stable-2020.08-1/arm-buildroot-linux-gnueabihf/sysroot/You can now invoked the program with the following command:
qemu-arm -L $LD_LIBRARY_PATH ./sexpr
