Steve, Thanks for your advice.
I know that sometimes --generate-sea can take a long time. Also if you are creating a map for a country that has lots of tags on every node, then it will take a lot more memory. This is unfortunate and I plan to fix that problem, but it does mean that you should probably split the file into more pieces if that is the case. You are running java with more virtual memory than you have physical memory on your machine which is also guaranteed to be slow.
Like Apollinaris says: --generate-sea takes very long. And it doesn't work well with tiles, and depends on --ignore-osm-bounds which buggers intertile routing. So I compiled --generate-sea with a style with nothing but the coastline, which ran for 1.5 hr and gave me a lovely map with the land & sea seperated but nothing else. The plan is to use this in a mapset if I want to have a blue sea. Almost like an overlay, but maybe an underlay?
For me, it takes just over 4 minutes to do the UK split into 14 tiles, and 8 seconds to make the index.
I would recommend that you run the index creation separately from creating the .img files. The index should only take a few seconds to create once you have some .img files to work with, and will give you a lot more time to experiment if things don't work the first time.
Then run mkgmap with the --index on all the img file(s) that were created in the previous step, apart from the overview map file (called by default osmmap.img in the mdr branch, or 63240000.img in the mainline). Along with --index you will need as a minimum --family-id but there is no harm in repeating all the other options.
Then I compiled the img with 1260, --generate-sea off, --index on - I think the mdr branch is not included in 1260 yet? Because I only got the normal Imgs & tdbs.(this took max 5 minutes) Then I compiled with 1257 and --index. Gave me the mdr's and mdx's within 2 seconds. (I just realised I did not make the maps transparent, so I'll probably have to do it again - no sweat it takes less than 10 min without generate-sea.) Now I try to send it to mapsource - And realise I am still as stupid as I've always been :-/ [HKEY_LOCAL_MACHINE\Software\Garmin\MapSource\Families\uk-test] (uk-test = family-name?)

Every new dev is as exciting as the birth of a new baby, and I love to read how you all work through the various hick-ups & challenges!
