   Hi!

   I am midway through compiling the STM32F4 / LibMaple.

   I originally tried this through Win7, but decided to go back to Linux as this is my preferred choice when it comes to this sort of thing.

   Ref:

   http://leaflabs.com/docs/unix-toolchain.html#toolchain-test

   https://github.com/leaflabs/maple-ide

   https://github.com/gbulmer/openstm32sw/tree/master/stm32f4/libmaple

   This is where I am getting a little 'unstuck'.

   I am a little confused..

   Can I run the STM32F4 SW solo, or do I need the original source and then overwrite the original source with the F4 lib structure?

   I've tried both methods, and keep getting the same error.

   I have managed to get my discovery running with st-util / st-flash, but wished to use the Maple IDE as I am familiar with Arduino.

   These are the current errors I am getting (on make / make install):

   /home/sickform/src/NewMaple/libraries/mapleSDfat/SdFile.cpp: In member function 'uint8_t SdFile::rmRfStar()':
   /home/sickform/src/NewMaple/libraries/mapleSDfat/SdFile.cpp:912:40: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]

   arm-none-eabi-g++: error: unrecognized command line option '--print-gc-sections'
   arm-none-eabi-g++: error: unrecognized command line option '--march=armv7-m'
   make: *** [build/discovery_f4.elf] Error 1

   Any help on this would be appreciated.

   Thanks in advance.

   Clean install, clean build, basically a full start from scratch, and still getting the same errors..

   I managed to get the Maple IDE to compile and run correctly which suggests to me that I have done this in the right manner.

   How can I fix these issues and why are they occurring?

   I understand that what this error means 'comparison between signed and unsigned integer expressions [-Wsign-compare]', but haven't enough experience to fix it..

   I've looked through the relevant code but not sure as to how to solve this myself..

   Please could someone shed some light on this before I totally loose my mind?

   You should add more -Xlinker and -Xassembler flags to LDFLAGS in your makefile

   
LDFLAGS = -T$(LDDIR)/$(LDSCRIPT) -L$(LDDIR) \
-mcpu=cortex-m3 -mthumb -Xlinker \
--gc-sections -Xlinker --print-gc-sections -Xassembler --march=armv7-m -Wall

   Thank you mlundinse!

   I am one step closer..

   However, now getting back:

   In function `exit':
   > exit.c:(.text.exit+0x16): undefined reference to `_exit'
   > collect2: error: ld returned 1 exit status
   > make: *** [build/discovery_f4.elf] Error 1

   Also still getting the error:

   SdFile.cpp: In member function 'uint8_t SdFile::rmRfStar()':

   But guessing this is unnecessary for Maple to run?

   Please excuse my lack of knowledge..

   ..But Maple does open!

   The next couple of questions.. (Please bear with me).

   I've checked through the 'Tools / Board' menu, but no sign of the F4..
   Is this something to do with having relevant files in the right place?

   Will this allow me to upload direct to the board (ala Arduino) or will I need to do this manually with the ST-link?

   When now programming, via Maple, are all the GPIO now listed in the same fashion as a standard Maple board? (eg analogRead(pin)).

   Thanks in advance!

   ..Ah no..

   I have just realised I was actually in the wrong directory!
   (I was actually in the original maple IDE build folder!)

   So I haven't got it running.. My bad..

   I dont know about the SdFile stuff.

   The _exit function has been added in the main libmaple repository some weeks ago.

   Add the following to the end of wirish/syscalls.c

   
__weak void _exit(int exitcode) {
while (1)
;
}
`

   The resaon for the problems is that never versions of the gcc compiler suite is more picky about warnings.

    I'm not entirely sure I have the dir set up correctly.

    Can I just confirm that the LIBMaple folder goes inside the original build folder? (IE overwriting the original dirs?)

    I am only intending to use this for the F4..

    (Will try the wirish/syscalls.c now!)

    Very odd..

    No syscalls.c in the /wirish folder?!

    I got all of these fresh today so not sure of why this is.
    Would it be possible to request the links to the newest versions just incase?

    When you use the command line tools, use the libmaple and not the files from maple-ide.
    I am not sure what version gbulmers code builds on.

    How do I go about porting the F4 in to Libmaple?

    Now I feel totally lost.

    I'm guessing its not as simple as just copying everything over from the openstm lib?

    If I took an existing board (eg the F1) could I not change all the files and change them to what the F4 uses?

    Is there any reason why this would not work?
