problems running metareflect #3

Open gabyx opened 5 years ago

gabyx commented 5 years ago

I cannot quite get it to work: I compiled it with clang8.0.0 (head), it works with some minor CMakeList Adjustments (will send a PR...)

$BD/bin/metareflect test.hxx

Output:

Error while trying to load a compilation database:
Could not auto-detect compilation database for file "test.hxx"
No compilation database found in /Users/gabrielnuetzi/Documents/metareflect/example or any parent directory
fixed-compilation-database: Error while opening fixed database: No such file or directory

Running without flags.

Do you know the source of the problem? Thanks a lot!

you need to generate a file compile_commands.json, the content is like that:

 {
    "directory": "C:/EFF/Src/EFFBase",
    "command": "clang-tool -fms-extensions -fms-compatibility -fms-compatibility-version=19  -isystem \"C:/EFF/Include/EFFBase\"  -isystem \"C:/EFF/ThirdPartyLib/boost_1_68_0\"  -isystem \"C:/EFF/ThirdPartyLib\"  -isystem \"C:/EFF/ThirdPartyLib/EASTL-3.12.04/include\"  -isystem \"C:/EFF/ThirdPartyLib/EASTL-3.12.04/test/packages/EABase/include/Common\"  -isystem \"C:/EFF/ThirdPartyLib/yaml-cpp-0.5.3/include\"  -isystem \"C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.15.26726/include\"  -isystem \"C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Tools/MSVC/14.15.26726/atlmfc/include\"  -isystem \"C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Auxiliary/VS/include\"  -isystem \"C:/Program Files (x86)/Windows Kits/10/Include/10.0.17134.0/ucrt\"  -isystem \"C:/Program Files (x86)/Microsoft Visual Studio/2017/Community/VC/Auxiliary/VS/UnitTest/include\"  -isystem \"C:/Program Files (x86)/Windows Kits/10/Include/10.0.17134.0/um\"  -isystem \"C:/Program Files (x86)/Windows Kits/10/Include/10.0.17134.0/shared\"  -isystem \"C:/Program Files (x86)/Windows Kits/10/Include/10.0.17134.0/winrt\"  -isystem \"C:/Program Files (x86)/Windows Kits/10/Include/10.0.17134.0/cppwinrt\"  -isystem \"C:/Program Files (x86)/Windows Kits/NETFXSDK/4.6.1/Include/um\"  -D _DEBUG  -D _MT  -D _DLL  -D WIN32  -D _WINDOWS  -D EFFBASE_EXPORTS  -D USE_DL_PREFIX  -D NO_MALLINFO  -D YAML_DECLARE_STATIC  -D _UNICODE  -D UNICODE  -D CMAKE_INTDIR=\"Debug\"  -D EFFBase_EXPORTS  -D _WINDLL -std=c++14  \"C:/EFF/Src/EFFBase/EFFUtility.cpp\"",

  },

In the readme, you can find how to use cmake to generate this file. But if you use vistual studio, you need use a plugin Sourcetrail.
