How to avoid (or disable) C2220 (warning treated as error - no 'object' file generated) when building chromium 39.0.2171.65 on windows 7?

[Hubert]

Hi,

I got error when fetch and build chromium on windows 7. Could you give some help, thanks a log in advance!

Error when execute "gclient runhooks --force"

________ running 'download_from_google_storage --no_resume --platform=win32 --no_auth --bucket chromium-gn -s src/buildtools/win/gn.exe.sha1' in 'D:\Chromium\39.0.2171.65_follow'

Comment out the "download_from_google_storage " in src\.DEPS.git, run "ninja -C src/out/Release_x64 chrome", following error is got:

Thanks

 

PS: Whole script to set up the enviroment:

1. set environment

set DEPOT_TOOLS_WIN_TOOLCHAIN=0 rem http://www.chromium.org/developers/how-tos/build-instructions-windows

2. loading releae

fetch chromium rem wait for 8 hours to download the source code. Download WebKit takes very long time.

3. switch branch

git checkout -b your_release_branch 39.0.2171.65  # or more explicitly, tags/34.0.1847.9   http://www.chromium.org/developers/how-tos/get-the-code/working-with-release-branches

gclient sync --with_branch_heads --jobs 16

gclient runhooks --force rem to generate chrome.sln

4. build 

setx GYP_GENERATORS msvs-ninja,ninja /M  rem http://blog.csdn.net/Kuerjinjin/article/details/23563059

setx DEPOT_TOOLS_WIN_TOOLCHAIN 0 /M  rem http://www.chromium.org/developers/how-tos/build-instructions-windows

python src\build\gyp_chromium -Dcomponent=shared_library -Goutput_dir=out -Dtarget_arch=x64 

ninja -C src/out/Release_x64 chrome

Old branches require patching "c:\program files (x86)\microsoft visual studio 12.0\vc\include\xtree" to disable warning 4702 (there's another #pragma warning disable near the top of the file).

This is no longer required at head.

Thank you very much Scott Graham.

Could share me the solution of running "download_from_google_storage" failed?

I'm not sure what that is, I'd guess a proxy or something causing problems. If it's only gn.exe.sha1 that's failing it shouldn't be a problem as that's not yet used in the main build.

Hi Scott Graham,

Thanks a lot for your help!

I am confused, if it is a proxy issue, then other files should also cannot be downloaded, but not only download_from_google_storage.

Another issue is that, when I build master branch. Could you give some help?

That's from the msvs or msvs-ninja generator and can be ignored. (Those are all incorrect and should be cleaned up, but they don't affect the build.)

download_from_google_storage accesses a different host than the source files, so your proxy is blocking access specifically to google storage, but not the git servers.
