1373354 - mach buildsymbols fails building/running dump_syms.exe with Visual Studio 2015 Express: [Error 2] The system cannot find the file specified.

Status: NEW

(Firefox Build System :: General, defect)

Description

Attachment: mach buildsymbols errors

mach buildsymbols fails on Windows trying to run dump_syms.exe on certain files such as dlls that don't seem to exist. Log of errors is attached.

mozconfig shouldn't be controversial, just:

ac_add_options --enable-profiling
ac_add_options --enable-debug

mach build was run before mach buildsymbols.

I tried an opt build without the --enable-debug, and it still fails with the same result...

Comment 2

Further development: it appears dump_syms.exe is missing?

Comment 3

[Chris Manchester (limited bugmail, email directly)]

I was able to reproduce something like this in my Windows environment. dump_syms.exe was missing due to configure failing to find "dia2.h". I was able to dump and pack symbols locally after fiddling with my VS2017 installation and registering a relevant dll, so I don't think this stems from bug 1337986.

So it would appear this is related to me using 2015 express edition, which does not install the DIA SDK. And apparently there is no pre-built version of dump_syms.exe for VS 2015 in the tree, so I can't seem to just use the ones there for older versions...

Ugh. We should just print a useful error if you wind up in this situation. FWIW, the VS Community installers include the DIA SDK.
