Dockerfile attempt does not build under Ubuntu 18:04 #8

Closed zoobab closed 5 years ago

zoobab commented 6 years ago

Hi,

Just tried to compile the head of the git with a Dockerfile:

https://gitlab.com/zoobab/i2c-star/blob/master/Dockerfile

I ran the CI at gitlab (sorry there is no CI afaik on github, so I mirrored it to Gitlab):

https://gitlab.com/zoobab/i2c-star/-/jobs/94547265

Which ends up with this error:

  CC      util.c

  LD      i2c-explorer.elf

Any idea how to fix it?

This looks like it is likely to be a problem with your toolset (it does not support -mfloat-abi=hard).

It would be best to adopt a better toolset but you can probably workaround by not building the STM32F4 applications:

make src/bootloader src/i2c-stm32f1-usb

Alternatively you could hack at the FPU settings:

make FP_FLAGS=-mfloat-abi=soft

With "make src/bootloader src/i2c-stm32f1-usb" the build works now.

I tried to make a an automated build in Docker hub, it does not seem to like the git submodules --init --update part. Trying to find a work around.

Hope this was solved but I'm going to close it on the assumption it was a docker issue (e.g. nothing to do with i2c-star).
