apple-clang 9.0 error #1778

ovanes · 2017-09-20T13:04:17Z

Just upgraded Xcode and received new clang version 9.0.
This issue seems like an addon to: #1707

Now CMake produces the error:

Current conanbuildinfo.cmake directory: /some/build-dir
CMake Error at build/conanbuildinfo.cmake:724 (message):
  Incorrect 'apple-clang' version 'compiler.version=8.1' is not the one
  detected by CMake: 'AppleClang=9.0'
Call Stack (most recent call first):

  build/conanbuildinfo.cmake:817 (check_compiler_version)
  build/conanbuildinfo.cmake:571 (conan_check_compiler)
  CMakeLists.txt:18 (conan_basic_setup)

I changed clang versions in the ~/.conan/settings.yml, that did not help. Afterwards I updated conan and was told that settings.yml was migrated.

Conan version is now:

$conan --version
Conan version 0.27.0

Steps to reproduce:

Install todays Xcode upgrade
create a new build directory and cd there
run conan install .. --build=missing
run cmake ..

Notes

Seems like conan switched to profiles.
I suspect that cmake now determines the compiler name as AppleClang instead of apple-clang => modified settings.yml and edited profiles/default to use:

[settings]
arch = x86_64
build_type = Release
compiler = AppleClang
compiler.version = 9.0
os = Macos
compiler.libcxx = libc++

Now conan started to recompile the modules. Will report if that helped.

The text was updated successfully, but these errors were encountered:

memsharded · 2017-09-20T13:33:58Z

Yes, now the defaults settings are stored in .conan/profiles/default, and [settings_defaults] shouldn't exist in conan.conf

But the compiler is still called apple-clang in conan, so you shouldn't change it.

Could it be that your bare cmake invocation (after the install) is still using the older Xcode 8.1 apple-clang, instead of the new one?

ovanes · 2017-09-20T14:05:56Z

I appended [settings_defaults] there, but there were not used. After the migration this section was not there.

When I run cmake after conan install .. I receive this full output:

make ..

Just to be sure, I ran afterwards:

After the full rebuild of the modules, I still the the error from above.

lasote · 2017-09-20T14:15:21Z

Look at the file .conan/profiles/default. It should be adjusted to apple-clang 9

Even grepping for 8.1 through the previously wiped build directory points to the log file:

./cmake-build-debug/CMakeFiles/CMakeOutput.log

containing:

The system is: Darwin - 16.7.0 - x86_64
Compiling the CXX compiler identification source file "CMakeCXXCompilerId.cpp" succeeded.
Compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ 
Build flags: 
Id flags:  

The output was:
0


Compilation of the CXX compiler identification source "CMakeCXXCompilerId.cpp" produced "a.out"

The CXX compiler identification is AppleClang, found in "/my-home/my-project-dir/cmake-build-debug/CMakeFiles/3.8.1/CompilerIdCXX/a.out"

Using:

$ strings ./cmake-build-debug/CMakeFiles/3.8.1/CompilerIdCXX/a.out

produces:

INFO:compiler[AppleClang]
INFO:platform[Darwin]
INFO:arch[]
INFO:dialect_default[98]
INFO:compiler_version[00000009.00000000.00000000.09000037]

As log file states my system runs cmake 3.8.1 and that's why I find the log file... Lucky co-incidence.

Thanks for the feedback, having a look.

memsharded · 2017-09-20T14:38:01Z

Lets try to reduce it so something smaller that we can reproduce. Please try a very simple package creation:

$ conan new Hello/0.1 -s -t
$ conan create user/testing

Paste the whole output here. Thanks!

I just grepped through my own package directory and see that there in test_package directory built modules refer to clang 8.1.

.//conan-zmq/test_package/build/ebf9df4f1d1163cb42855db8c26e6d33cf2f6112/conaninfo.txt:    compiler.version=8.1

And these modules were deployed on my local system using conan test_package command. Can that be a problem?

Yes, that could be related, but not sure how.

The packages are built and installed for 9.0, which is right. It is in the local command that your build system is picking the wrong configuration somehow. Not sure how to debug it. Are you in slack or hangouts? Please ping us to info@conan.io, maybe we could arrange some interactive pair debugging

ovanes · 2017-09-20T16:49:29Z

Many thanks @lasote
My CMakeLists.txt had that inclusion:

if(EXISTS ${CMAKE_CURRENT_SOURCE_DIR}/build/conanbuildinfo.cmake) #Clion, with conanbuildinfo.cmake in build folder
    include(${CMAKE_CURRENT_SOURCE_DIR}/build/conanbuildinfo.cmake)
else()
    include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake) # Not CLion
endif()

Which was wrong, because I was using the CLion build directory: cmake-build-debug and in fact build directory was also existing, so this if caused cmake to load config from the abandoned build directory and therefore the compiler check failed :(

The solution was:

if(EXISTS ${CMAKE_BINARY_DIR}/conanbuildinfo.cmake) 
    include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
endif()
