Hello,
I am trying to make a program in visual c/c++ for configuring a specific vendor modem via http(s). For this purpose, I am trying and testing with v8, I need to take some variable values at runtime and use them in the next POST or GET requests, but no luck with v8. There are several javascript files downloaded from devices, but all of them even fail to compile.They does not seem to have any error from from an editor, are not modifiable because every time it is retrieved from modem. There are not problems configuring modems from popular browsers, chrome included; they don't find errors. e.g. It is a file md5.js downloaded from modem( http://www.mediafire.com/file/avtnmgdaonxc7ci/md5.js/file <http://www.google.com/url?q=http%3A%2F%2Fwww.mediafire.com%2Ffile%2Favtnmgdaonxc7ci%2Fmd5.js%2Ffile&sa=D&sntz=1&usg=AFQjCNFsb7Wpapkprar9_Eyk8TmQGqbIeg> ) I begin from hello_world sample modified a little with shell example: adding ReportException function in order to take more information from compile fails: *G:\c++\projects\v8hello\x64\Debug>v8helloundefined:260: SyntaxError: Unexpected token >> 8 * ((i+1)%4)) & 0xFF) << 8 )^SyntaxError: Unexpected token >* where this is line 249(not 260): (((binarray[i+1 >> 2] *>>* 8 * ((i+1)%4)) & 0xFF) << 8 ) , and I cannot find any error there, brackets seem ok etc. The bitwise shift right is the problem, but why ? There bitwise shift right & left before this statement, but they do not take attention of the compiler. the source is: *// Copyright 2015 the V8 project authors.
