Eagle freezes if run from ulp to generate gerber files

e14 Contributor

I have a ULP to automate generation of gerberfiles.

In the ULP I use the following command:

 

system("\"" + EagleExe + "\" -X -x0.0 -y0.0 -O+ -c- -dGERBER_RS274X -o\"" + GerberFileName + "\" \"" + B.name + "\" tPlace tNames");

 

This usually works fine but in some cases it just freezes and nothing happens.

If I run the CAM processor manually i get the following warning:

Fullscreen contentimage_31710.html Download 
<html><head><title>Jive SBS</title></head>
<body><font face="arial,helvetica,sans-serif">
<b>Error</b><br><font size="-1">
An general error occurred while processing your request.
</font></font></body></html>

 

The ULP probably freezes because of this warning, but the warning is not shown.

Eagle is probably waiting for me to answer the non visible dialog.

Is there some "silent mode" without warnings or some other way to sole this problem?

    Not sure why, but Eagle is waiting for input from the stdin.  Even if

    stdin is not a tty, it sits there and waits.

     

    I managed to fix this by echoing an "n" to stdin.  It's been working

    consistently ever since.  Even if it never eats the character, there's

    one ready to be read.  Here's a few lines I use to generate a complete

    set of gerber files:

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-TopCopper.gbr 516800.brd 1 17 18 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-BotCopper.gbr 516800.brd 16 17 18 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-NonPTHoles.gbr 516800.brd 20 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-TopSilkScreen.gbr 516800.brd 21 25 || exit 1

    516800-RevA-BotSilkScreen.gbr 516800.brd 22 26 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-TopMask.gbr 516800.brd 29 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-BotMask.gbr 516800.brd 30 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    516800-RevA-TopPaste.gbr 516800.brd 31 || exit 1

     

    echo n | eagle -X -N- -f+ -O+ -c- -x0 -y0 -dGERBER_RS274X -o

    -dEXCELLON -o 516800-RevA-ExcellonDrill.exc 516800.brd 44 45 || exit 1

    Thank you!

    This works great, but since I use a ULP and (I think) you use a bat-file i had to add "CMD.EXE /c echo y | " in the system call.


    system("CMD.EXE /c echo y | \"" + EagleExe + "\" -X -x0.0 -y0.0 -O+ -c- -dGERBER_RS274X -o\"" + GerberFileName + "\" \"" + B.name + "\" Top Pads Vias");

     

    Simple explanation of variables used:

    "EagleExe" is a string set to the full path of Eagle.exe

    "GerberFileName" is a string set to output path and filename

    B.name is the filename of the board
