16.04 Ubuntu x64 machine, any help appreciated and thanks

Have you installed ncursesw? (libncursesw5-dev package i guess) EDIT: i now see that ncursesw is missing from our build dep section in readme, i'm sorry!

[ggodreau]

Thanks FedeDP! Installed libncursesw5-dev (as well as the 32bit variant), still receive the following:

Mmmh did you run a "cmake ../" again before building? I cannot see any issue (you should have every dep installed)...

[ggodreau]

@FedeDP Yep - did a full re-clone as well. All dependencies seem to be satisfied, along with a proper SLACK_TOKEN env variable. Same error :-/

[FedeDP]

Can you try to add a "message(${CURSES_INCLUDE_DIR})" line right after "find_package(Ncursesw REQUIRED)" line, in CMakeLists.txt, then run again:

cmake ../

Finally, paste here the output of the command! Thank you very much!

EDIT: can you paste me the output of

pkg-config --cflags-only-I ncursesw

too?

[ggodreau]

@FedeDP

cmake:

greg@gregdev:~/ga/slack/build$ cmake ../

pkg-config

greg@gregdev:~/ga/slack/build$ pkg-config --cflags-only-I ncursesw
-I/usr/include/ncursesw

[FedeDP]

Found the issue! Can you please retry? Note that you'll now need pkg-config to be installed too. Remember to remove old build/ folder in order to let cmake clean build the package.

[ggodreau]

Hooray - thank you! Issue confirmed fixed commit a712bbe5f4d89a0920689b50efaebf7ca2991050 @FedeDP
