[Scons-users] error: stray '\' in program

[Mahmood Naderan]

It seems that replacing 'echo' with 'echo -e' resolves the issue.

Thanks

yes, you have to change your "echo" command, such that the output
    into the versionFile gets split into two lines with a single #define
    each. Try out the "echo" line in your shell first, to make sure it
    works. Then copy it back to the Command() call in your SConstruct.

Best regards,

Dirk
