[Scons-users] Command line is too long Error in windows 64bit machine

[Gouru, SrinivasReddy CCS]

Hi

I am using Scons with Renesas Compiler in windows platform ( 32 and 64 bit). I have too many libraries to link in liker stage. While linking I got an error like “ Command Line is too long”.
After some investigation I found the solution which is given below. I have applied this on 32 bit windows system and it is working fine.


if env['PLATFORM'] == 'win32':
    import win32file
    import win32event
    import win32process
    import win32security

    def my_spawn(sh, escape, cmd, args, spawnenv):
        for var in spawnenv:
            spawnenv[var] = spawnenv[var].encode('ascii', 'replace')

        sAttrs = win32security.SECURITY_ATTRIBUTES()
        StartupInfo = win32process.STARTUPINFO()
        newargs = ' '.join(map(escape, args[1:]))
        cmdline = cmd + " " + newargs

        # check for any special operating system commands
        if cmd == 'del':
            for arg in args[1:]:
                win32file.DeleteFile(arg)
            exit_code = 0
        else:
            # otherwise execute the command.
            hProcess, hThread, dwPid, dwTid = win32process.CreateProcess(None, cmdline, None, None, 1, 0, spawnenv, None, StartupInfo)
            win32event.WaitForSingleObject(hProcess, win32event.INFINITE)
            exit_code = win32process.GetExitCodeProcess(hProcess)
            win32file.CloseHandle(hProcess);
            win32file.CloseHandle(hThread);
        return exit_code

    env['SPAWN'] = my_spawn

But while compiling on windows 64 bit machine I got some errors.
Error is:

= Linking start.abs
scons: *** [start.abs] error : (87, 'CreateProcess', 'The parameter is incorrect.')
Traceback (most recent call last):

  File "C:\Python27\Lib\site-packages\scons-2.3.0\SCons\Action.py", line 584, in __call__
    stat = self.execute(target, source, env, executor=executor)
  File "C:\Python27\Lib\site-packages\scons-2.3.0\SCons\Action.py", line 806, in execute
    result = spawn(shell, escape, cmd_line[0], cmd_line, ENV)
  File "D:\root\build\rtu\tt2\main\ecs2_131078\ccrx\SConstruct", line 82, in my_spawn
    hProcess, hThread, dwPid, dwTid = win32process.CreateProcess(None, cmdline, None, None, 1, 0, spawnenv, None, StartupInfo)
error: (87, 'CreateProcess', 'The parameter is incorrect.')

I thought like, above solution is not compatible with windows 64 bit. Can you please provide me the solution which will work on windows 32 as well as 64 bit machine.

Thanks,
Srinivas
