[ SOLVED ] Linux Mint 19.3 unable to compile latest Dev release

[nbohr1more]

It seems that something unfriendly to Ubuntu \ Debian snuck into the Dev trunk?

/dolphin-emu/Source/Core/Common/MsgHandler.h:85:20: error: invalid use of void expression
      ##__VA_ARGS__)
                   ^
/dolphin-emu/Source/Core/Common/MsgHandler.h:100:3: note: in expansion of macro ‘GenericAlertFmt’
  GenericAlertFmt(true, Common::MsgType::Warning, MASTER_LOG, format, ##__VA_ARGS__)
  ^~~~~~~~~~~~~~~
/dolphin-emu/Source/Core/Common/Assert.h:37:12: note: in expansion of macro ‘PanicYesNoFmt’
      if (!PanicYesNoFmt("An error occurred.\n\n"                                                  \


Please let me know if there are alternate compile instructions or if this is a known issue?

OK, when I blow out my install directory and start from scratch it is failing on a different error:

[ 35%] Building CXX object Externals/glslang/CMakeFiles/glslang.dir/glslang/OSDependent/Unix/ossource.cpp.o
[ 35%] Linking CXX static library libglslang.a

Builds fine for me on Pop_OS 21.10. Are you running this in the root of the git before attempting to build? 

Code:

git submodule update --init --recursive

It looks like the version of fmt that you have isn't the one required, which is true on Ubuntu. When running cmake, you should see this:

Quote:CMake Warning at CMakeLists.txt:567 (find_package):

  Could not find a configuration file for package "fmt" that is compatible
  with requested version "8.0".

  The following configuration files were considered but not accepted:

    /usr/lib/x86_64-linux-gnu/cmake/fmt/fmt-config.cmake, version: 7.1.3
    /lib/x86_64-linux-gnu/cmake/fmt/fmt-config.cmake, version: 7.1.3



-- Using static fmt from Externals
-- Module support is disabled.
-- Version: 8.1.1
-- Build type: Release

Tried a recursive submodule init

It only seems to grab mGBA and QT submodules?

Do you have any additional errors earlier in the log?

Yes, those are Dolphin's only submodules.

Yes, it seems that fmt strikes again?

I guess I could see if there is a more modern fmt than the one that ships in Mint?

ASSERT is just a macro. I feel like you have more messages to show (where that ASSERT is used).
Also, latest master compiles fine for me on Ubuntu 20.04.

Linux Mint 19.3 is based on Ubuntu 18.04, and both of them use an older version of gcc/g++ that doesn't seem to play nicely with the external fmt library that Dolphin provides. Your two options are to upgrade to Linux Mint 20.3 (Ubuntu 20.04) or update your compiler on Linux Mint 19.3.

If you want to keep using Linux Mint 19.3, here's what I tested on Linux Mint 19.3 Cinnamon:

Spoiler: (Show Spoiler)

# Install gcc-9/g++-9:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update && sudo apt upgrade
sudo apt install gcc-9 g++-9

# You can change your default gcc compiler to gcc-9 if you want by following this post (change 8 for 9):
https://askubuntu.com/a/1028656

# Confirm you have gcc-9 installed
gcc-9 -v
(if you changed the default) gcc -v

# Follow the build instructions for Dolphin on Linux
https://wiki.dolphin-emu.org/index.php?title=Building_Dolphin_on_Linux
(I had to run the `sudo apt install <packages> again cause I broke my Qt5 install messing around testing various things)

# If you still have your old git folder that's fine too, just delete the `build` folder you created and start fresh

# If you changed your default gcc to gcc-9, then just run through building as normal

# If you didn't change your default, you have to run cmake to point to gcc-9
cmake .. -DCMAKE_C_COMPILER=gcc-9 -DCMAKE_CXX_COMPILER=g++-9

# The first few lines of the cmake output will tell you if it's using gcc 9.4.0 or gcc 7.7.0

# Build Dolphin
make -j$(nproc)

# Create a bash script if you want that'll run through the make process for you. An example is on the Building Dolphin for Linux page

Woo!!! Thank you very much! I am back to compiling dev again
