'Filename too long' issue when checking out WebRTC source

[Jose Antonio Olivera Ortega]

Hi there,

I am trying to check out the WebRTC sources on windows (Windows 10) and I am hitting the 'Filename too long' issue.

Note I am checking out the sources from Cygwin but It worked correctly before. The script I use basically does the following:

$ gclient.bat config --name ${SRC_PATH} https://chromium.googlesource.com/external/webrtc.git

$ export GYP_DEFINES="include_tests=0 target_arch=ia32"

$ export DEPOT_TOOLS_WIN_TOOLCHAIN=0

$ export GYP_MSVS_VERSION=2013

$ gclient.bat sync -n -D --with_branch_heads

$ gclient.bat runhooks

After some time it aborts and shows the following error:

[0:22:53] fatal: cannot create directory at 'third_party/WebKit/LayoutTests/imported/wpt/html/semantics/embedded-content/media-elements/synchronising-multiple-media-elements/media-controllers': Filename too long

----------------------------------------

Have you guys experienced this before? Thanks!

Cheers,

jaoo.

Maybe not the answer you wanted, but I'd check out from a more shallow directory.

>>> len(" C:\Users\user\jenkins\workspace\task-build-webrtc\CONFIGURATION\Release\PLATFORM\windows\src\chromium\src/third_party/WebKit/LayoutTests/imported/wpt/html/semantics/embedded-content/media-elements/synchronising-multiple-media-elements/media-controllers")

252

"In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character."

So either way it looks very close to the limit.
