CEF Forum

i'm trying to update to the current cef version (trunk r1971), and get this error message at startup:

Code: Select all

[0118/015708:FATAL:isolate_holder.cc(55)] Couldn't mmap v8 natives data file

this thread suggests adding natives_blob.bin and snapshot_blob.bin to the resources dir, so I did that but the error still occurs.

anything else that could be causing this?

What OS?

64 bit linux

it looks like the problem is that my resources path is completely ignored

for testing I did this:

Code: Select all

CefSettings settings;
CefString(&settings.resources_dir_path).FromASCII("/boguspath");
CefInitialize(args, settings, cefApp.get(), nullptr);


and get this error:

Code: Select all

[0124/005016:ERROR:icu_util.cc(149)] Couldn't mmap /home/sunflare/ssd_cache/aspera/build/icudtl.dat

the path above is where the binary is.
shouldn't it search for icudtl.dat in /boguspath?

No, the path to icudtl.dat is hard-coded in Chromium relative to the executable and cannot be configured via resources_dir_path.

ok, are natives_blob.bin and snapshot_blob.bin hard-coded the same way?

I don't have the code in front of me at the moment but I believe so.

alright, that explains it

thank you for your help
