There are quite some differences between the F1 and the F4 chips. Thats what the ala and bulmer forks are adressing. Unfortunately these changes have not been added into the main libmaple repository, while some other changes to the main repository have not been added to the F4 libraries.
Its a bit of a mess really, needs a super maintainer to set up a great community version of th libmaple and the IDE.

Any suggestions as to how I can move on from this in the meantime?
Is this down to certain versions of the GCC and ARM toolchains?
I have been looking now for quite some time, but the information is either quite scarce or I don't understand the lingo.
I was attempting to make a natural progression from the DUE to the F4 as it has DSP and FPU, plus the extra speed!
I've been trying to make this happen for some time now, and not really getting on well with CoIDE Eclipse or similar..
Hence going this route.
I wish I knew more about all this as I would have loved to help out to make this happen!

Not sure if this is relevant etc, but going to post it up just incase anyone can shed some light..

Use my libmaple F4 port from https://github.com/AeroQuad/AeroQuad/tree/master/Libmaple
Add -nostartfiles to the LDFLAGSSTM32 definintion in the makefile to get rid of the __bss_start__, __bss_end__ and _exit errors.
You will get and linker error complaining about _init, define this somewhere:
void __attribute ((weak))_init(void){};

Hi ala42.
Thanks for forwarding this..
One problem, I cant seem to get the link to download, how do I go about this?
Do I need to sign in etc? I tried to do this before but there are no links to wget etc?!
(I sign in but unsure how to access / download to dir in the standard fashion eg git clone.. wget..)

I had a version from here, but this had similar issues?

With:

-mcpu=cortex-m3 -mthumb -Xlinker -nostartfiles\

I get the error as before..
Have I got '-nostartfiles' in the correct place?
There is a zip button on the github site. You can also use https://github.com/AeroQuad/AeroQuad/archive/master.zip

I have found this in the documentation supplied with Maple IDE:
"Build Instructions
------------------------------------------------------------------------------
You first need to set the environment variables LIB_MAPLE_HOME to the
path containing the libmaple repo, and BREATHE_HOME to the path
containing the breathe repo. [FIXME: using env. vars. is hackish].
This will enable you to build the documentation. Check that this
worked with:
$ cd $LIB_MAPLE_HOME/docs
$ doxygen
$ make html
Sphinx should build the docs with no trouble, ending in "The HTML
pages are in build/html". Please ignore any warnings.
If that worked, you're now ready to place the IDE's various libmaple
dependencies into their respective places. There's a hackish script
in the libmaple repo which will get the details right for you. From
$LIB_MAPLE_HOME, run
$ ./support/scripts/copy-to-ide <--path to IDE directory-->
Where <--path to IDE directory--> gets replaced with the path
containing the IDE repository. This will copy the libmaple source
tree over, then rebuild the documentation and copy it over. You are
now ready to compile the IDE itself.
From the build/ directory, select the appropriate subdirectory based
on your target platform. Run make.sh from within that directory.
Linux:
$ cd build/linux
$ ./make.sh"
I am a little lost as what to do next?
I can't seem to find any information on 'Breathe' or even how to pull this part together..
Would this enable me to run the F4 and upload entirely from within Maple IDE?
Once I have built Libmaple for the F4, how do I then include it in to the compile of Maple IDE?
