Thanks, Hendrikto. Fixed.

I got the error:

CMake Error at /usr/share/cmake-3.19/Modules/CMakeDetermineCCompiler.cmake:49 (message):
  Could not find compiler set in environment variable CC:

  gcc-9.
Call Stack (most recent call first):
  CMakeLists.txt:22 (project)


CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

This can be fixed by using CC=gcc.

Thanks, jaantoots, PKGBUILD updated and CC and CXX set to use gcc-9.

I think there is no need to add gcc to makedepends as it is already pulled in as a dependency of cuda.

Missing gcc8 from makedepends.

And until https://github.com/ethereum-mining/ethminer/issues/2027 has been fixed, need to remove that line to build with CUDA 11.0, e.g.:

sed -i '/arch=compute_30/d' libethash-cuda/CMakeLists.txt

Thanks!

vanja_z, thanks for pointing out the typo (which actually existed since the first commit, hadn't to to anything with the latest fix). I've corrected it to 'CXX'.

Hi, the fix doesn't work for me, you should have:

export CXX=g++-8

not

export CCX=g++-8

Thank you, semeion. I've fixed the issue for both ethminer-cuda and ethminer.

Tried the version without CUDA and got similar errors.

How to compile this package? Some tip?

I am getting that errors, what can i to do?
