I am having a problem with a project that I'm trying to set up for my new STM32F7 Nucleo Board. I freshly installed the GNU ARM Embedded toolchain, STM32CubeF7 and the GNU MCU Eclipse Plugin, with which I set up a new Project on my Windows 7 machine at work. I have previously done that at home on my Ubuntu Laptop without issues. After I set up the project, I added the HAL and the CMSIS libraries and used a template project from STM32CubeF7. So far the compilation works fine, but when linking I get the following error:
c:/program files (x86)/gnu tools arm embedded/5.4 2016q2/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -lc_p-lc_p
To my understanding the issue here is that some library with a very strange name can not be found. Unfortunately the only page that I found where the same error is described is in Russian, which I don't speak at all.
At first glance, to me it looks like the generated makefile is corrupted, and a library called c_p is trying to be linked, but it is done twice without a space in between. So it could be an issue with Eclipse or the Eclipse GNU MCU Plugin.
Things that I tried to get rid of the error:
- Update Eclipse
- Downgrade to several old versions of the GNU ARM Embedded toolchain
- Turn off/on the following linker options:
--specs=nano.specs-nodefaultlibs-nostdlib
- Install the toolchain in a folder without any spaces
Here's the automatically generated makefile:

Does anybody have any inputs with this for me?
EDIT: GNU MCU Eclipse Plugin provides a template for new projects, even with this I get the same error.
