[llvm-dev] Gauging interest in generating PDBs from LLVM-backed languages

[Johan Wehrli via llvm-dev]

Hi Mike,

I have experienced something similar with the DIA SDK.

Most of the time, it is a path problem: https://support.microsoft.com/en-us/kb/3035999 <https://support.microsoft.com/en-us/kb/3035999>

If you open the file cmake/config-ix.cmake you will find the place where cmake check if the DIA_SDK is present (there is also a note saying that sometime this is a Windows bug).

You can modify the line "set(MSVC_DIA_SDK_DIR "$ENV{VSINSTALLDIR}DIA SDK”)” by "set(MSVC_DIA_SDK_DIR “C:\\path\\to\\DIA SDK”)”.

In my case, it was working.

Hope this help.

Greetings,

Johan

If you build the llvm-pdbdump tool you can run it with the "raw" subcommand to dump lots of low level info from the file.

I ran across llvm-pdbdump earlier but couldn't get it to build on a vanilla 3.8 install (CMake is convinced I don't have the DIA SDK and I haven't found a way to change its mind). I stopped short of reading the code though so I wasn't aware of how much is actually there!
