Hello there, I shall continue with some questions if I may :) ... please! is info about the instruction set stored in an executable? ie can i verify the version of the arch of an executable, just as I can find out the arch using the command 'file' ?
I am asking because even though i filled in the necessary variable with armv4t as export SBOX_EXTRA_CROSS_ARGS=-march=armv4t would compile a simple hello world with -march=armv5te COLLECT_GCC_OPTIONS='-v' '-o' 'hello6' '-march=armv5te' '-funwind-tables' I must explicitly add the gcc option -march=armv4t to get the executable I want. Another major question is. I need to do some development on an 2.4.18 kernel (!). is there a legacy scratchbox version that compiles against 2.4 kernels? I could either install a legacy version, or use a toolchain that I received with the arm board based on a custom kernel. If I go for the latter, will I have any change of succeeding in building a toolchain for scratchbox out of this toolchain?
