xcodebuild: error: 'sokol-tools.xcodeproj' does not exist.

[nosakou]

Hello sokol-tools team. I am trying to build sokol-tools through a README file of your project and getting an error as follows:

sokol-tools % ./fips build

xcodebuild: error: 'sokol-tools.xcodeproj' does not exist.
[ERROR] Failed to build config 'osx-xcode-release' of project 'sokol-tools'

The steps are as per README as I mentioned above for MacOS using osx-xcode-release:

Tools I have installed:

• Python 3.9.6
• cmake version 3.23.2
• XCode Version 14.3.1 (14E300c)

MacOS version Ventura 13.5 (22G74)

Have looked through the closed issues and did not found a relevant one. Could you help to solve the problem, please?

[floooh]

...hmm somehow the cmake generation step is missing, it should look like this:

sokol-tools ➤ ./fips build
=== building: osx-xcode-debug
=== generating: osx-xcode-debug
config file: /Users/floh/projects/fips/configs/osx-xcode-debug.yml
Preset CMake variables:

  CMAKE_BUILD_TYPE="Debug"
  CMAKE_OSX_SYSROOT="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk"
  FIPS_AUTO_IMPORT="ON"
  FIPS_CONFIG="osx-xcode-debug"
  FIPS_LOCAL_BUILD="OFF"
...

Can you run ./fips clean all followed by ./fips gen and post the output here?

(e.g. it might be that a previous attempt at generating the project files has failed, the build directory has been left in an incomplete state)

[nosakou]

Yeah, sure:

./fips gen
=== generating: osx-xcode-release
config file: /Users/yulianosakova/PycharmProjects/wanna-utils/wanna_utils/envmap_processing/renderer/tools/fips/configs/osx-xcode-release.yml

  FIPS_AUTO_IMPORT="ON"
  FIPS_CONFIG="osx-xcode-release"
  FIPS_LOCAL_BUILD="OFF"

[nosakou]

Actually I resolved it by adding to sokol-tools/CMakeLists.txt a couple of environment variables:

set(CMAKE_C_COMPILER "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc")
set(CMAKE_CXX_COMPILER "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++")

The destination of the both files I found with: xcrun --find cxx xcrun --find cc

[floooh]

That should not be needed, can you check if the Xcode command line tools are installed?

Either run xcode-select --install on the command line or check in Xcode => Setting => Locations, there's a dropdown called Command Line Tools - both should put the Apple clang toolchain into the path (e.g. you should be able to run clang --version in the terminal.

[nosakou]

xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" in System Settings to install updates

and

clang --version
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: x86_64-apple-darwin22.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

[nosakou]

Without setting the variables to the CMakeLists.txt I am having the same build error as mentioned above.

[floooh]

...that is super weird, the output of xcode-select and clang looks correct...

I wonder if cmake is actually trying to run cc and c++ to detect the compiler.

Can you try cc --version and c++ version on the terminal?

...and also, AFAIK cmake looks at the environment variables CC and CXX, maybe those are overriden? (e.g. try echo $CC and echo $CXX, those should be empty.

(PS: while at it, also check whether the CPATH, CFLAGS and CXXFLAGS environment variables are set, I've come across quite a few Mac users who had set those because sometimes that's recommended by homebrew and then had trouble building projects)

[nosakou]

cc --version
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: x86_64-apple-darwin22.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

and

c++ --version
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: x86_64-apple-darwin22.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

echo commands for the both $CXX and $CC are empty. So the CXXFLAGS, CPATH, CFLAGS are. If it is makes sence I have 2,3 GHz 8-Core Intel Core i9 processor though AFAIK M1 users do not have this problem with build as I do. But I am not sure if the processor architecture is the reason here.

I'm out of ideas tbh, it shouldn't be an ARM vs Intel thing, but let me check on my Intel Mac (I don't have uptodate macOS and Xcode on there though).

PS: nvm, I need to setup Github access first again, somehow my ssh key was deleted or is expired.

[floooh]

...so in general it works on my Intel Mac, the compiler is detected:

sokol-tools ➤ ./fips gen

...I'm on fairly old versions though:

• macOS Big Sur 11.7.8
• Xcode 12.5.1

clang version output:

...maybe it's cmake? What does cmake --version say? I have 3.23.1 on the Intel Mac.

[nosakou]

This is the cmake version:

cmake --version                                                                                                
cmake version 3.23.2

[floooh]

Also looks good. Sorry now I'm really out of ideas..

[nosakou]

That's OK, at least I found a workaround :-)
