The problem is that I dont have the <cyg/fileio/limits.h> header in my install tree also the <cyg/posix/pthread.h> header and I don't know why the confgtool did not generate these file when I build the library, Is it a problem of version of the configtool or what??
Hi, also this seems a problem on the eCos library configuration generated with the configtool. I used the configuration I suggested in a previous post (and that you adopted!) and I'm able to compile your example. Some warnings, but no errors. The inclusion tree is the following: "pthread.h" "pkgconf/isoinfra.h" "cyg/posix/pthread.h" The latter include the declarations that you miss. Please, check it. Your "standard_Posix" configuration should be good.
