Yesod app deployment as CGI program -


already managed create yesod application running in "yesod -d devel". after that, modified in article configure yesod app cgi (i'm restricted cgi , won't have of development tools nor ghc on production environment) , did rebuild 

cabal-dev clean && cabal-dev configure && cabal-dev build

calling resulting binary hand simulate cgi environment, response:

invalid environment, valid entries are: [development,testing,staging,production]

while --help gives me that:

usage: yussuf <environment> [--port <port>] valid environments: [development,testing,staging,production]

when pass "production" first parameter, following response occurs:

getaddrinfo: not exist (name or service not known)

so doing wrong? additional parameter mean i'll need sort of wrapper script correctly call application, or how work?

getaddrinfo: not exist (name or service not known) typically means dns query failed.

matlab - How to equate a structure array to structure array -

the following code doesn't work, think it's clear want do: my.struct = 1; foo.bar = my.struct; so that foo.bar.struct = 1 basically want fill in my structure array bunch of fields , values. want place struct nested struct within foo.bar while retaining field names. my.struct = 1; foo.bar = my.struct; this places value of my.struct (= 1 ) in foo.bar . of course foo.bar 1 . i think you're after this: my.struct = 1 foo.bar = my;
