According to the GL 4.4 core specification, section 2.2.2 ("Data
Conversions For State Query Commands"):
"If a command returning integer data is called, such as GetIntegerv or
GetInteger64v, a boolean value of TRUE or FALSE is interpreted as one
or zero, respectively. A floating-point value is rounded to the nearest
integer, unless the value is an RGBA color component, a DepthRange
value, or a depth buffer clear value. In these cases, the query command
converts the floating-point value to an integer according to the INT
entry of table 18.2; a value not in [−1, 1] converts to an undefined
value."
The INT entry of table 18.2 shows that b = 32, meaning the expectation
is to convert it to a 32-bit integer value.

dEQP-GLES3.functional.state_query.floats.color_clear_value_getinteger64

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
