Trouble linker

[Kaj Toet]

I'm trying to built the chardriver, however I get undefined references
in libsys.a, for chardriver_task, chardriver_announce, and the nop*
calls. Any idea how to solve this? I used the same makefile as in the
tutorial.

Are you trying to build the system with or without modifications?

I'm not quite sure what you're doing, so it would help if you could
explain a few more details.

Could you please post the information suggested by the following page?

Hi,

I'm running the latest Minix 3 version (from the download page) in
Virtualbox.

I mistakenly said I was building the chardriver, but I did try to use
the chardriver as with the example here:
http://wiki.minix3.org/en/DevelopersGuide/DriverProgramming

I followed every step accordingly. However, as said I get undefined
references (in libsys.a, for chardriver_task, chardriver_announce, and
the nop*
calls) when compiling the example (linker errors).

I do not think I needed to install extra packages (as far as I know).

Thank you for you time,

kutkut

In libsys.a???

Are you linking with libchardriver?

I followed the guide as well, and I found that it is a bit outdated in
some places. In some places I had to deviate from the examples to
avoid errors or other problems. From what I saw, the first and second
Hello driver examples basically worked, while the Time driver example
had many errors.

I don't remember seeing these.

I did see this for nop_signal. I used "nop_alarm" instead, since it
seems to have the same behavior. I don't know what "nop_signal" would
correspond to more correctly though.

Basically, the examples need to be updated. I was about to, but I
don't know what is preferred for some sections.

I hope this helps,
