cmake . returns error on MAC OS XI Captain version 10.11.6 upon compiling dealii-8.5.0-brew.dmg

[Wakil Sarfaraz]

Hi all,

I have been away from deal.ii for almost two years.

I have come back and wanted to install the most updated version which is dealii-8.5.0-brew.dmg

When I attempted to cmake the step-1 of the examples, it returns error containing the following texts:

-- The C compiler identification is unknown

-- The CXX compiler identification is unknown

CMake Error at CMakeLists.txt:38 (PROJECT):

  The CMAKE_C_COMPILER:

    /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment

  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to

  the compiler, or to the compiler name if it is in the PATH.

I will greatly appreciate your help on this.

Hi,

Make sure you have XCode installed as well as command line tools: xcode-select --install

Regards,

Denis.

Hi Denis,

Xcode is installed on my machine. It is just that I deleted the dmg files associated to previous versions of deal.ii and cmake, which was perfectly working.

When I downloaded the new versions today, it returned these errors.

Best,

Hi Wakil,

so command line tools are installed, did you check?

CMake tells you the error: 

 The CMAKE_C_COMPILER:

    /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc

  is not a full path to an existing compiler tool.

so see whether you have this or not. Perhaps something changes in between macOS versions, I won't be surprized. The dmg you download are built with specific version (probably Sierra or High Sierra) using Apple's clang. So if location of compiler changes between those versions, then there is a problem. 

Regards,

Denis

you can also try a pre-release package from this post:

Hi Denis,

The command line tool is installed as shown in this:

Wakils-MBP:~ wakilsarfaraz$ sudo xcode-select --install

Password:

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

Wakils-MBP:~ wakilsarfaraz$ 

I will check the other suggestion you sent,

thanks for your effort.

Best

Wakil

Can this new version be installed on Mac without a dmg file?

Apologies if the question is too basic.

Best,

Wakil

In version 9.0.0 the examples directory is no longer located in /Applications/deal.II-9.0.0.app/Contents/Resources/examples,

Could you please help me allocated this?

Thanks,

Wakil,

The deal.II source directory can be found under

/Applications/deal.II-9.0.0.app/Contents/Resources/spack/src/deal.II-9.0.0

There you will find the examples directory.

In the new package (that I’m building right now), you’ll also have in the usual location.

Best,
Luca.
