When i am compiling file offline the emblocks IDE is showing following error messages

.objs\main.o||In function `DigitalOut':| C:\Users\Shuzon\Desktop\mbed_blinky\mbed\DigitalOut.h:49||undefined reference to `gpio_init_out'| c:\program files (x86)\emblocks\2.30\share\em_armgcc\bin\..\lib\gcc\arm-none-eabi\4.7.3\..\..\..\..\arm-none-eabi\lib\armv7-m\crt0.o||In function `_start':| (.text+0x4a)||undefined reference to `wrap_main'|

undefined reference to `gpio_init_out' and undefined reference to `wrap_main' any idea how to solve the problem ??

not so far...

Remove the line (which includes the word wrap) from Project build options | Linker settings | Other options

Leaving Other options blank fixed this link error for me in emBlocks.

thanks Kit Adams !

I am still getting this error !

Any solution ??

It looks like you are not linking to the mbed library. Also your main.cpp looks different from the mbed one I get:

#include "mbed.h"

DigitalOut myled(LED1);

int main() {
    while(1) {
        myled = 1; // LED is ON
        wait(0.2); // 200 ms
        myled = 0; // LED is OFF
        wait(1.0); // 1 sec
    }
}

I find that the latest version of this project, created on mbed and exported for emblocks, compiles and links without errors in emblocks 2.30 even with the "wrap" linker options present. I only needed to remove that option for an older exported project which linked against some older files.

I suggest you start again, creating a new version of the blinky project for your hardware on mbed and export it again.

no luck with the offline compiler.... thanks by the way

Can you send me your project files ??

I only have a Nucleo F401RE, so here is the complete emblocks project: /media/uploads/spinorkit/nucleo_blink_ledf401re.zip

Emblocks compilel F401 fine but do not compile F103
