Im having an issue with gerber files generated from Eagle.
Looking at the gerbers with viewplot and everything is okay, except some of the drill holes arent present, on the polarized caps, some of the transistors and the big input film cap.
Whats up with that? and how do I fix it?
Note : Im using the standard libraries that comes with Eagle so that shouldnt be an issue.
Ran drillcfg.ulp, create excellon drill files from the .drl file with excellon.cam and then I created the gerber files with gerb274x.cam.

Thats a serious bug and I thought Eagle was quite a mature package.
I would get in touch with them and see what they say, there might be a software patch out for it.

I doubt the holes are actually missing in Eagle. Either the gerbers have not been created properly (extra layer included), the gerber viewer has an issue or maybe a minor operator error. The gerber viewer is not part of Eagle.
I have no problem with drills on eagle.
To see the drills corectly you will need the right file to be read by gerbv.
The file has extension *.txt , You can get 2 or more drill files as the manufactures needs.
Maybe you have to check again your cam generator settings.

Are the files standard excellon or extended excellon?
Extended excellon is similar to RS273X in that it will generate its own tool table, whereas standard excellon you have to create a drill table or it will ignore the holes. Extended excellon look similar to:
M48
METRIC,TZ
T01C.25
T02C.45
T03C1.4
T04C3.5

;T02 Holesize 2. = 0.450000 Tolerance = +0.000000/-0.000000 PLATED MM Quantity = 143

Myself, I dont use Gerbers and Excellon any more as its old fashioned and can be a total pain, ODB++ is a much better format, less prone to errors and more manufacturer friendly. I dont know whether Eagle caters for this format, as I use Cadstar.

Like I said, I created a .drl file, made the Excellon file with that and then made the gerbers.
But some of the holes dont show, tried it a few times, same result. Weird.
Going to use makepcb.com, following their guide right here : http://makepcb.com/media/convert eagle files to gerber files.pdf

Well, found a cam file from sparkfun(sfe-gerb274x.cam) file that outputs :
* Top and bottom copper (.GTL, .GBL)
* Top and bottom solder mask (.GTS, .GBS)
* Top and bottom silkscreen (.GTO, .GBO)
* Drill file, 2.4 leading (.TXT)
It output a .dri file as well.
And it looks as it should, see attached image.
Would that be enough for most boardhouses or do they need more?

Those files that you show are ok.
You could see at iteadstudio or seedstudio.
Check the specifications of each boardhouse. Some times they need the files with other extensions or gerber format.
I tried this:
IteadStudio(more cheaper than ->),seedstudio.

Hi Neutrality,
I use a modified version of the sparkfun CAM file. I remember there was a layer missing, I think it was the component labels are missing. Anyway, worth double checking.
I have about half a dozen single-sided boards made using my modified CAM file and no problems so far. 😀
