geez

the entry point is untraceable
the entry point of procedure putc_unlocked is untraceable in the library of dynamic lyaisons cygwin1.dll

It might be that you have a same name dll but in different areas (folders) on your pc. It's a possibility that can give such an error. The wrong version but same name dll is being accessed by your application (which won't work).

thkx falcon it was that...

i replace all version of cygwin1.dll by the newest version in all reps and it's run oki !

thkx a lot !!!

thanks
