Windres syntax error message

[allynm]

Hello everyone,

I am working in the latest version of MinGW (downloaded 12/12/2011). I am attempting to compile a .rc file using Windres.exe. I use the command: windres -O coff about1.rc -o about1.res. Windres generates perhaps 100 or more warning messages saying "null characters ignored", and then it terminates with the message: "About1.rc:1:syntax error".

There are no null characters in the source file. To add to the puzzle, exactly the same About1.rc file compiles smoothly if I use MSFT rc.exe. The resulting .res file links with the program .obj file and runs smoothly.

I have tried using the switch --use-temp-file in the command line, and this does not solve the problem.

Anybody have a suggestion?

Thanks
Mark Allyn

windres --input=about1.rc --input-format=rc --output=about1.res --output-format=coff

you would link in the .res file by including that on the command line like a .cpp file, just like you would do to link in a .o or .a lib file

this works for Manifest XML Resource files as well to make things vista/7/8 compatible. there is a special usage of that format just to make it work with all platforms.
