Suggestion

Please add support for this cool open source build tool https://xmake.io/#/

I have tried to use it as "buildsystem: simple" in my manifest file, but flatpak builder doesn't find it

[TingPing]

I don't believe any more build system types will be added, xmake doesn't look particularly popular.

This is the correct way to do it. If you post an example maybe something obvious can be seen. You of course have to build xmake in your manifest.

Very sorry to hear that

Oh I see, that's interesting. Will try that, thanks!

[paulross80]

I had a problem. The build tool compiled just fine, but then flatpak-builder cannot find it

My manifest file (com.my_apps.JustCpp.yml):

  - ./scripts/get.sh __local__ __install_only__

Does it not support make install? The main thing you need to make sure of it is that it uses PREFIX=/app not ~/.local, probably removing __local__ helps but it may default to /usr/local.

  # - source ~/.xmake/profile # ?

This does nothing useful. The shell only exists for that module.

  # git submodule update --init # enable if needed!

This also will do nothing. No network access.

  - cd ./xmake

You can replace this with subdir: xmake if needed.

[paulross80]

Does it not support make install?

I saw this part from the get.sh script:

# do install
if test_z "$prefix"; then
    prefix=~/.local
fi
if test_nz "$prefix"; then
    $make -C $projectdir --no-print-directory install PREFIX="$prefix" || raise "install failed!"
else
    $sudoprefix $make -C $projectdir --no-print-directory install || raise "install failed!"
fi

Should I add this as parameter to that script? PREFIX=/app. Or this should be an env var?

[TingPing]

I would do this:

  - name: xmake
    make-install-args: ['PREFIX=/app']
    subdir: xmake
    cleanup: ['*']
    sources:
      - type: git
        url: https://github.com/xmake-io/xmake.git

I have pasted your exact code. I got a new error

How can I fix it?

[TingPing]

Add no-autogen: true, I was thinking it would be optional.

I have also tried to modify the original code, but it keeps installing to the default path instead of /app

      # https://xmake.io/#/guide/installation

[TingPing]

Oh you don't need subdir: xmake, I was just going off your cd.

[paulross80]

Almost there! I configure my build tool to output to /app

- name: just_cpp
    buildsystem: simple
    build-commands:
      # ${FLATPAK_DEST} ?
      - xmake f -m debug -o /app
      - xmake

But now it doesn't find a header from the C++ std library

(When I compile my app outside flatpak-builder, it works, there is no error in the source code of my app)

[TingPing]

<print> is part of C++23, the compiler maybe too old or need to the flag for that to be enabled. Worst case clang is available also.

(It is insane for a buildsystem to depend on C++23, maybe there is an option)

[paulross80]

I'm sorry if I wasn't clear enough. The build tool (xmake) seems to be compiling and working fine now. The problem is now with my app. My gcc compiler is the latest:

g++ --version
g++ (GCC) 14.2.1 20240912 (Red Hat 14.2.1-3)

My main.cpp file

#include <print>

int main()
{
    std::println("Hello World!");
    return 0;
}

Starting of my xmake project file:

-- Project name
set_project("just_cpp")

-- Global settings
-- C++ standard
set_languages("c++23")

I'm specifically asking the build tool to enable C++23 for me. When I compile this project without flatpak-builder, everything compiles and runs just fine:

➜  just_cpp git:(main) ✗ xmake
[100%]: build ok, spent 0.174s
➜  just_cpp git:(main) ✗ xmake run 
Hello World!

[TingPing]

My gcc compiler is the latest:

The compiler is in the flatpak runtime. flatpak run --command=g++ org.freedesktop.Sdk//24.08 --version

[TingPing]

Oh switch your runtime to 24.08 not 23.08 which is a year old.

[paulross80]

Flatpak runs its own compiler? I'm sorry, I didn't know that. And we've got a new error (I have previously completely erased the build folder and the hidden .flatpak-builder/)

xmake f -m debug -o /app

You probably don't want to output binaries to /app, maybe to $FLATPAK_BUILDER_BUILDDIR. Then you would install the binaries you care about. I assume xmake features that.

[TingPing]

I'm going to close this since the feature won't be added. I hope I've pointed you in the right direction, now its just about using xmake properly which I don't know anything about.
