CMAKE fails

[bbuske]

Hello,

I am trying to use cmake to compile Dolphin on openSUSE Leap 42.2. I encountered some errors and issues, mainly due to outdated compilers and missing dependencies. However, now with all that, the process is running nearly fine, until an error again jumps in. This time however, I have no idea, what causes it or how to fix it. See here:  

Code:

bbuske@linux-9igo:~/Downloads/Build/dolphin-emu/dolphin$ cmake ..
-- Detected architecture: x86_64
-- X11 support enabled
-- Xrandr found
-- Checking for module 'xi>=1.5.0'
--

Call Stack (most recent call first):

Any ideas or suggestions?



Edit: Attached the error.log which I had forgotten.

Now that's surprising...

It says right there:

Code:

-- Checking for module '[b]xi>=1.5.0[/b]'
--  
CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:363 (message):
[b]A required package was not found[b]

xi seems to be a library for X. Maybe try to install libXi-devel and/or libXext-devel or whatever they are named in openSUSE.

Hello,

thanks for your reply. This (with adding some more missing packages) worked. I think I just struggled finding the name of the missing package. libXi actually did it. However, CMAKE terminated fine, but the final make install fails with the following error:

Code:

[100%] Linking CXX executable ../../../Binaries/dolphin-emu
../../../Externals/wxWidgets3/libwx.a(utilsgtk.cpp.o): In function `GetSM()':

Any idea on fixing this?

Still no fix on this one..
Despite several attempts and trying.

From the guide for building on Linux: https://wiki.dolphin-emu.org/index.php?title=Building_Dolphin_on_Linux

"The development version of Dolphin requires at least WxWidgets 3.1.0, so you don't need install libwxbase3.0-dev and libwxgtk3.0-dev; Dolphin will build it from Externals folder.

Add -DUSE_SHARED_ENET=ON on cmake line if you want to build dolphin against shared libenet-dev."

You need to have the libenet-dev installed on openSUSE; I think this is "libenet7" and "enet-devel". openSUSE doesn't have the latest libwxgtk3.0 or WxWidgets 3.1 packaged, nor does it have the static libraries, which is why you get the error messages:

"../../../Externals/wxWidgets3/libwx.a(utilsgtk.cpp.o): In function `GetSM()':"

The linker is looking for a static library that just isn't there. There hasn't been a static library for openSUSE in a long time, but if you use the flag mentioned above with cmake, Dolphin will correctly compile and link the shared enet libraries. This works for me on openSUSE Leap 42.3 as of 12/2017 and Dolphin version Dolphin 5.0-6084 from GIT on x64 using gcc-5 and g++-5.

Hope that helps!

But the text you quoted says something different:

Aka Dolphin already ship with WxWidget 3.1 sources that is compiled. The line just says that the linker that links with the self-build WxWidget library can't find the 3 functions "SmcOpenConnection", "SmcVendor" and "SmcOpenConnection", which appear in the function GetSM() of that library.

Probably the author installed the development packages, but maybe not the binary packages. It seems the "SmcOpenConnection" function is in libSM (part of X). On the openSUSE package search I can find libSM and libSM6.

It's been a while since the OP was on the Dolphin Forums. If they haven't solved their problems in the meantime time, it'd be better to make a new thread if they come back asking about CMake, especially with updated info on their situation.
