c++ - CUDA C - library error from cutil.h to helper_cuda.h -


i have project developed in c, on cuda 4.0. try compile on cuda 5.0 have problem cutil.h, have changed cutil helper_cuda.h , receive error always:

in file included /path/to/helper_cuda.h:24

and

/path/to/helper_string.h:18: fatal error: fstream: no such file or directory

fstream c++ library, how can compile without have error?

sorry english :d

my suggestion:

  1. load cuda 4.0 sdk on cuda 5.0 setup
  2. build cuda 4.0 sdk using cuda 5 toolkit (nvcc, etc.)
  3. now include same header files , link against same libraries (that built) correspond cutil arrangement cuda 4.0 sdk.

helper_cuda.h not drop-in replacement cutil.h discovering. likely, if worked past fstream issue, might run one, depending on components out of cutil project using.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
