make error

[mark-hahn]

I'm trying to build the 1.5 generator on ubuntu. I'm using clang 3.2 and gcc version 4.6.3. My cmake command is ...

cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_CONFIG_EXECUTABLE=/root/llvm32build/bin/llvm-config -DCMAKE_BUILD_TYPE=Release

The cmake seems to succeed. I'm getting this output on make ...

Scanning dependencies of target codebrowser_generator

make[2]: *** [CMakeFiles/codebrowser_generator.dir/main.cpp.o] Error 1
make[1]: *** [CMakeFiles/codebrowser_generator.dir/all] Error 2
make: *** [all] Error 2

What am I doing wrong?

You need at lease gcc 4.7 because i am using C++11 constructs. You can also compile with clang using

cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_CONFIG_EXECUTABLE=/root/llvm32build/bin/llvm-config -DCMAKE_BUILD_TYPE=Release  -DCMAKE_CXX_COMPILER=/root/llvm32build/bin/clang++

However, I must admit I have not tried clang 3.2 for a long time so there might be errors. If possible, you should upgrade to 3.3 or 3.4. Else, please report the error and i will try to fix them.

Having trouble building it with clang 3.3

cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_CONFIG_EXECUTABLE=/usr/local/bin/llvm-config -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=/usr/local/bin/clang++

make

can you try VERBOSE=1 make ?
