What am I missing? - Bare metal development hwlibs not compiling

[ACarp2]

Hello,

I am trying to create a project and compile with the hwlibs for bare metal development. I am working on a Cyclone V development board in DS-5 & I cannot compile the hwlibs because I get a lot of errors about many many things undefined. Examples are UART_MAX_LEN, off_t, and log_buf. It seems like there is a large file or set of files I am missing full of #defines for this specific chip. Can anyone help me, or does my question make sense?

Hello, I would like to know which Baremetal lib are you using? also I need to know which quartus version did you use? By defining the Quartus version, I can use the same DS-5 version and replicate the issue. Thanks

I am not sure which Baremetal lib I am using. I Am just trying to find one that works. I did not use quartus in this process, as I am just trying to work with the hps for now. However, I am using DS-5 and Quartus 15.1.

I am facing the same issue, I have used Quartus 18.1 and EDS SoC 16.0 to build a bare-metal project. It gives following error while compiling :

I'm also facing this very same problem. Would be much appreciated if anyone could provide help.
