ppapi_tests fails to compile on Win64 build
Project Member Reported by, Feb 22 2013 Back to list
This is the last thing Blocking the Win64 "All" build. So, I'd really like to get it fixed, otherwise I have to disable NaCl for now in the Win64 build (because I need to get the "All" target working on the CQ ASAP now that we have bots on the main waterfall).

Here's the output:

[6/599] CC obj\ppapi\tests\ppapi_tests.test_struct_sizes.obj
FAILED: ninja -t msvc -o obj\ppapi\tests\ppapi_tests.test_struct_sizes.obj -e environment.x64 -- cl.exe /nologo /showIncludes /FC @obj\ppapi\tests\ppapi_tests.test_struct_sizes.obj.rsp /c ..\..\ppapi\tests\test_struct_sizes.c /Foobj\ppapi\tests\ppapi_tests.test_struct_sizes.obj /Fdobj\ppapi\ppapi_tests.pdb
d:\src\chrome\src\ppapi\tests\arch_dependent_sizes_64.h(14) : error C2118: negative subscript

[6/599] CXX obj\chrome_frame\crash_reporting\crash_report.crash_report.obj

So, it looks like this target is picking up the wrong architecture, and thus failing the compile asserts, but I don't see how.

By default, msvc _x64_ sizeof(long int) == 4, so the size check fails in arch_dependent_sizes_64.h.  On linux x64, sizeof(long int) == 8.

Khronos (gl.h) and ppapi/c/ppb_opengles2.h define GLintptr in terms of long int:
  typedef signed   long  int     khronos_intptr_t;
  typedef long int GLintptr;

The following revision refers to this bug:

r184296 | | 2013-02-23T06:17:14.304007Z

Changed paths:

Disable GL sizes PPAPI tests

The wrong size is defined for Win64. It needs a real fix, but first I need to unblock the builder.

In case it's not obvious, the test is valid, and this probably means OpenGL won't work right in NaCl on Win64 until it's fixed.

(Makes sense to disable though to unblock other Win64 work.)

Yup. That's why the bug is still open. :)

Any progress here?
fyi, recent updates that may allow the test to be re-enabled:

Thanks Nicholas. Working on the CL to re-enable.
