Hello again,
Thank you for your help.
I encounter anotger problem that could signify the end between eCos and
I for my project... :(
After having some simple examples working, i tried to make one using
Dynamic ELF loading (dlopen).
So I tried first to compile eCos from the template stm32f4discovery +
posix (that compiles), and then adding the package "Dynamic Loder". A
conflict is resolved, setting the header to <cyg/loader/dlfcn>,
but then with no more conflict the command Build / Library crash and
doesn't want to compile "services/loader/current/src/loader.cxx"
Do you see what does it come from ? I see in the traces some undefined
macros, but It doesn't seems to be the main problem.
By the way, I have seen through experimentations in order to resolve
this issue, a difference between CYGPKG_HAL_CORTEXM and CYGPKG_HAL_ARM.
So I would know : doesn't a cortexm platform be considered as an ARM one
? Why not ? Is it a cause of my problem ?
Cheers, and thank you again.
Valentin BOUSSON
end of traces :
