#31 Cannot compile avarice-2.14.tar.bz2 due to '__unused'

[Maximilian Gerhardt]

Downloading the latest version in on this page, unpacking, configuring and building it leads to the errors

jtag3io.cc:353:42: error: expected ‘,’ or ‘...’ before ‘__unused’
  353 | void jtag3::changeBitRate(int newBitRate __unused)

That's on Ubuntu 20.04 with GCC version 9.3.0. The __unused keyword seems to make problems here.

Doing a quick replace-with-nothing using

sed -i -e 's/__unused//g' src/jtag*.cc

makes the program compile after another make.

Hi Maximilian,

randomly I raised a ticket on same issue at nearly the same time. I also tried to remove "__unused", it compiled, but nothing was installed using make install. Have you the same problem?

Regards,
Jörg

For installing you need to give it the install directory in the initial ./configure command, like mkdir ~/avarice_installed and ./configure --prefix ~/avarice_installed and then make && make install. But for me, I just grabbed the executable in src/avarice.

Is this not fixed in r390?

[Joerg Wunsch]

Yep, it is. Feel free to close this bug ticket.
