# # CORTEX # # Introduction --------------- This software is an coredump to text crash_report generator for userland application. It's reading a coredump file and extract useful datas that it output in a ordened way. These files can be submitted as crash logs to authors of softwares. The main purpose is for embedded systems where storing a coredump file is not always possible and using gdb is to heavy. # How to build cortex ----------------------- cortex is machine dependant, and cannot be cross-analyzing core. The purpose of this software is to be embedded on the target, thus removing the need to cross analyze. To build cortex follow these steps: - ./configure --host=<toolchainname> - make - make install The --host is optional (required for cross compiling). The BFD_ARCH and BFD_MACH variables are optional. if you want to be able to disassemble hex opcodes. They correspond respectively to "enum bfd_architecture" and some defines in bfd.h (from binutils). If they are not provided at configure time, they will be guessed based on target toolchain arch. The CFLAGS_ARCH is also optional. It define if we are using a 32 or 64 bits arch and also define the ELF e_type. Usually, the arch.mk and configure should guess correct values for those variables, but on some specific targets, you might need to set it at configure time. Examples on how to fully customize cortex for your target architecture. on a i386 machine to compile cortex - For an i386 target: $> ./configure - For a generic arm target: $> ./configure --host=arm-none-linux-gnueabi - For a specific armv5te target: $> ./configure --host=arm-none-linux-gnueabi BFD_MACH=bfd_mach_arm_5TE - For a specific mips target: $> ./configure --host=mips-none-linux BFD_MACH=bfd_mach_mips3000 CFLAGS_ARCH="-DLINUX32 -DMACHINE=EM_MIPS_RS3_LE" # Supported Architectures -------------------------- cortex work for several processor architectures: - i386 / i486 / i586 / i686 - x86_64 - arm # license ---------- cortex is distributed under the term of the General Public License version 2 (GPLv2) See gpl-2.0.txt for the full license content # author ---------- Tristan Lelong <tristan.lelong@blunderer.org>
