Ruby.h no such file or directory parser.o Error -


using rails 3.1 , new app, when go run bundle install got following errors

installing json<1.7.3> native extensions error: failed build gem native extension. creating makefile generating parser-i386-mingw32.def compiling parser.c in file included parser.rl:1:0:../fbuffer/fbuffer.h:6:18: fatal error: ruby.h: no such file or directory compilation terminated. make: *** [parser.o] error 1

i have installed devkit , change $path below:

c:\users\peter\downloads\make-3.81-bin\bin; c:\users\peter\working\ruby-devkit\mingw\bin; c:\users\peter\working\ruby-devkit; c:\program files\imagemagick-6.7.8-q16; c:\ruby193\bin;c:\ruby\bin;

you need install ruby development kit because windows looking source code ruby based on error missing ruby.h

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
