compile error on OS X 10.10.5 Yosemite about codebrowser

[ogoffart]

Hi, thanks for the bug report.
I have not been testing OSX for a long time.
I just made a commit that might solve your problems.

What version of libclang do you have?

You have libclang 3.3. (one can see that in your path: llvm33 )

This is way too old. (The OSX instructions are actually terribly outdated. I should fix that.)

I recommand that you get clang 3.7.

[Sumenia]

Ok Ok i was blind enough not to notice that.

Step 1 : brew remove llvm33
Step 2 : brew install -vd llvm --with-libcxx --with-clang --with-rtti ( --with-rtti because " --rtti" is deprecated" ) (12 min to compile all llvm .... something i won't do again..... OS X (rather Xcode), come with latest llvm build )
Step 3 : cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_CONFIG_EXECUTABLE=/usr/local/opt/llvm/bin/llvm-config -DCMAKE_BUILD_TYPE=Release
( correct llvm-config path)

Step 4 : make

Step 5 :

Oh, this is a link error.
I have no idea what the problem is. But it looks related to exceptions.

Can you try adding this line to generator/CMakeFiles.txt

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-exceptions")

Normaly I would expect the flag to be detected but perhaps it's not.

otherwise, please do

VERBOSE=1  make

so we can see what exact options are passed to the command line

[Sumenia]

Ok i did not notice that "brew install llvm" downloaded and compiled "LLVM 3.6.2".
I just downloaded the LLVM 3.7.0 Pre-Built Binaries for Mac OS X from their website , changed the path in CMake and it compiled flawlessly

[Sumenia]

I tested what you suggested and added :

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-exceptions")

in generator/CMakeFiles.txt

and tried to compile again (fresh git clone) with "LLVM 3.6.2" and no more link error and compiled !

I think we're done here. Thx
