Re: [Dotgnu-general] Porting dotnet to Minix 3

[Alexander Samilovskih]

sorry, yes I meant dirent. Yes I tried this macro, but it ends up in

it helped me to compile valuable amount of code, but stops on this
http://pastebin.com/tfm4ZYZK
with virtual memory exhausted, my workaround bring memory leak in
code? or this is related to minix runtime. If i choose 128 bytes for
var result, then assersion from malloc.c thrown
