Did you follow the instructions from https://github.com/mujx/nheko#building? Also what is your cmake version?

dset0x commented 6 years ago

@mujx Woops. I did not. Unfortunately it doesn't seem to make a difference:

cmake -Hdeps -B.deps -DUSE_BUNDLED_BOOST=OFF DUSE_BUNDLED_SPDLOG=OFF .            # mind you I had to add a `.` here.

Same pthread issue in the CMakeError.log file.

I also tried switching the *BUNDLED* directives on and off.

There is an omission regarding the INCLUDE_DIR flags.

Could you try the following

rm -rf .deps
rm -rf build

# Installing dependencies
cmake -Hdeps -B.deps -DUSE_BUNDLED_BOOST=OFF
cmake --build .deps --config Release

# Build nheko
cmake -H. -Bbuild \
  -DLMDBXX_INCLUDE_DIR=.deps/usr/include \
  -DTWEENY_INCLUDE_DIR=.deps/usr/include
cmake --build build --config Release

There was a bit of whining during cmake --build .deps --config Release:

... and it worked. Thank you so much.
