[opensuse-factory] CMake & ncurses
Hi, new kid on the block here. I'm one of the developers for the Yoshimi soft-synth, and have recently been informed that it won't compile on Leap 42.1/42.2. It seems that the version of ncurses here doesn't have a .pc file, so CMake's find_package function is unable to locate it. Is this just an oversight, or done deliberately for some reason? Can anyone suggest an alternative way for CMake to identify ncurses? -- Will J Godfrey -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Hi Until the version is at =>6 it looks like no pc file... Add SET(LIBNCURSES_LDFLAGS "-lncurses -ltinfo") in your CMakeLists.txt? -- Cheers Malcolm °¿° SUSE Knowledge Partner (Linux Counter #276890) openSUSE Leap 42.1|GNOME 3.16.2|4.1.34-33-default up 11 days 6:19, 3 users, load average: 0.40, 0.42, 0.37 CPU AMD Athlon(tm) II X4 635 @ 2.90GHz | GPU Nvidia GeForce 8800 GT -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Well yes, AFAICS, upstream does not ship any .pc files to begin with. Whatever pc file you have been relying on, it smells like a distro-specific hack.
Add SET(LIBNCURSES_LDFLAGS "-lncurses -ltinfo") in your CMakeLists.txt?
That sort of eschews ncurses6. It would appear that ncurses is still config scripts, i.e. `ncursesw6-config --libs` and so on. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Cmake upstream has a separate FindCurses package which should also be in openSUSE, this doesn't need the .pc file and you should be using that instead of the generic find_package function probably. https://cmake.org/cmake/help/v3.0/module/FindCurses.html -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adeliade Australia, UTC+9:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B

ncurses can generate .pc files since at least v5.8, it just needs to be configured with --enable-pc-files. -dnh -- I distinctly remember forgetting that. -Clara Barton -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

CMake already does this, it is just used slightly differently to the way many other projects are found with cmake which is probably causing the issue here. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adeliade Australia, UTC+9:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B

Thanks everyone for such a quick response. After studying the docs, I now have it compiling without ncurses.pc on my usual distros. I try to dig out a spare machine to install leap on and try there too. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

It seems the answer to this was remarkably simple :o <magic_incantation> set(CURSES_NEED_NCURSES TRUE) find_package (Curses REQUIRED) </magic_incantation> That works across all the distros I can get my hands on :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
