Ah phew. So far so good then.

Thank you for your support. I know it's not something you have to provide in anyway so I really appreciate it.

I will definitely check out that course. I grew up on DOS and Windows and know my way around those with ease but have always been blind to Linux so setting up the Pi was a real eye opener!

Well that didn't work either, still got the out of memory error.

Are you certain the export flag command should fix this and you mentioned this:

I will try again but can't see where I'm going wrong.

Do I need to clone the git again or can I just type:

make clean
export CXXFLAGS="-WI,--no-keep-memory"
make

and that should work? Just to clarify is it -WI as in letter l for lima for number 1 I should be using? if it is l for lima does it matter is its lower case l or upper case L?

Here is my kernal log:

You'll need export that in CXXFLAGS before running configure.

I think I may have figured out where I went wrong. On my iPhone the export flag command looked like "-WI (Whiskey India) but on my PC it looks like "-Wl (Whiskey lima) so I think I used i instead of l and the uppercase i (I) looks the same as a lowercase l on my phone.

So of all the stupid things to get tripped up on...

So I've typed:
make clean
export CXXFLAGS="-Wl,--no-keep-memory"
./configure
make

And now it's gonna do its thing for 8 hours. So hopefully it will work this time.

Gonna have to give up.

Even when running

make clean
export CXXFLAGS="-Wl,--no-keep-memory"
./configure
make

I'm still getting the out of memory error.

Thankyou for all the advice.

The CXXFLAGS="-Wl,--no-keep-memory" options only reduces the amount of memory the GCC linker requires, so an OOM is still possible with the full set of engines.

If you just want to play the SCI games, then can I suggest:
./configure --disable-all-engines --enable-engines=sci,sci32 && make clean && make

That will built ScummVM with just the SCI and SCI32 engines.

Another option would be to do a dynamic plugins build using:
./configure --enable-plugins --default-dynamic && make clean && make

This avoid the need to link a hug static binary at the end.

Thanks I'll give it a try.

Is it worth changing the RAM split from CPU/GPU 256/256 to 384/128 or is virtual memory the issue and not RAM?

You could try that, but the issue is mainly the lack of Virtual Memory / Swap.

This affects native compilation on many of the embedded device targets as most have limited RAM i.e. 512M or less and use Flash memory which if used as Swap would wear out fairly quickly and fail.

Another option would be to add an external hard disk partition as swap space (NOT the SD card as that is Flash memory). See:
https://raspberrypi.stackexchange.com/questions/70/how-to-set-up-swap-space

I guess you should also pass that to LDFLAGS and not CXXFLAGS. CXXFLAGS won't be passed to the linker command.

Yea it complies and when it says Linker is when it aborts.

So if I type

export LDFLAGS="-Wl,--no-keep-memory"

That should help?

I'll also try a USB swap drive.

I take it there's nowhere to get a pre-compiled version of 1.7.0 lol!

Well I don't know what did it or if it was a mixture but I changed the memory split on the RAM to give the CPU as much as possible and ran both export CXXFLAGS and LDFLAGS and set it off overnight.

This morning when I awoke it had compiled!! I ran make install and got an error but it was a permissions error so just ran sudo make install and it seemed to do it's thing ok!

I haven't yet ran ScummVM to check it loads 1.7.0 as I was SSH'd in from my PC and had to leave for work but I will try it tonight and report back!

You guys are legends!! It works!!

Thank you to everyone that helped me.

I must have grabbed the latest daily build as it says I have 1.8.0!!! Are there any juicy updates I should know about in this release? Twisted Evil

Again, thank you all. If anyone needs any help compiling for Pi in future just give me a shout.

Just to confirm what the other guy was saying. 1.4.1 exits back to Emulation Station fine in RetroPie but the 1.8.0 git build just crashes the Pi when you try to exit back to Emulation Station. Not a huge issue just requires a restart of the Pi.

I have a question. Is there any way to get a touchscreen working with scummvm? I have a 5" 800x400 HDMI LCD from waveshare. The touchscreen works perfect in raspbian, but in scummvm the cursor jumps along the edges of the screen when I press anywhere on the screen.
This results in Indiana Jones walking to the edges instead of where I touched the screen. Is there a way to get it to work properly?
