Generate Gerber files with eaglecon.exe

I'm using Eagle 7.7.0 and making ulp file to generate all gerber/drill files.

My code is

 

int pos = strstr(EAGLE_PATH, "eagle.exe");

dir_eaglecon = strsub(EAGLE_PATH, 0, pos) + "eaglecon.exe";

dir_eaglecon = replace_string(dir_eaglecon , "/" , "
" );

 

gerber_cmd = "cmd.exe /c " + dir_eaglecon;

 

string s;

sprintf(s, "%s -X -dGERBER_RS274X -o\"%s
%s%s\" \"%s%s\" %s", gerber_cmd, dir_gerber, release_name, gerberNames[i], dir_original, filename(B.name), gerberUsed[i]);

system(s);

 

it works perfectly with eaglecon.exe in C:\EAGLE-7.7.0\bin\

When I install program to C:\Program Files (x86)\EAGLE-7.7.0\bin\  ==> Error message: "...is not recognized as an internal or external command, operable program or batch file."

I'm aware that the new path of eaglecon.exe has "space" and need to be surrounded with quotation marks, so I update my code like:

 

gerber_cmd = "cmd.exe /c " + "\"" + dir_eaglecon + "\"";

 

However, the system(s) return 1 (Error) and cannot generate gerber file. In addition, when I manually type the command in cmd line, it also works perfectly with quotation in eaglecon.exe path.

 

Please kindly help to get it works with my new program directory. I've tried setup new path in environment variables but does't work so far.

Hi

Reading between the lines I suspect the spaces in the file path are

Generally I use single quotes to surround the file paths with spaces in

them. Not double quotes.

so your line

*gerber_cmd* = "cmd.exe /c " + dir_eaglecon;

would become

gerber_cmd = "cmd.exe /c " + "'" + dir_eaglecon + "'";

...or more elegantly......

sprintf(gerber_cmd,"cmd.exe -c '%s'",dir_eaglecon);

If you still have trouble post back here the resulting string 's'

created by the sprintf.

Hello Warren

Both the single/double quotes don't work. Below is the output that I printed out .txt file. (I re-installed to C:\EAGLE-7.7.0, but still prefer to solve this issue for all users)

EAGLE_PATH:

C:/EAGLE-7.7.0/bin/eagle.exe

EAGLECON_PATH:

C:\EAGLE-7.7.0\bin\eaglecon.exe

gerber_cmd:

cmd.exe /c 'C:\EAGLE-7.7.0\bin\eaglecon.exe'

I also tried to copy-paste string 's' to cmd line, the result below:

With single quotes '' - Syntax Error

With double quotes "" - Worked

So I guess using double quotes is correct, but don't know why system(s) failed to execute the command.

Hello again

After read thoroughly the article from Warren, I understand and solve this issue. The correct way is using ^" to surrounding path.

gerber_cmd = "cmd.exe /c " + "^\"" + dir_eaglecon + "^\"";

output:

s: cmd.exe /c ^"C:\EAGLE-7.7.0\bin\eaglecon.exe^" -X -dGERBER_RS274X -o"C:\Users\linhpt\Desktop\EPR\EPR100053\EPR100053-2\pcb\Gerber RS-274X\EPR100053-2.cmp" "C:\Users\linhpt\Desktop\EPR\EPR100053\EPR100053-1.3\EPR100053-1.3.brd" 1 17 18

system(s): 0

Thank you Warren!
