There is an specific list of texture targets that can be used with
glGetTextureImage. From OpenGL 4.5 spec, section '8.11 Texture Queries',
page 234 of the PDF:
"An INVALID_ENUM error is generated if the effective target is
not one of TEXTURE_1D , TEXTURE_2D , TEXTURE_3D , TEXTURE_1D_-
ARRAY , TEXTURE_2D_ARRAY , TEXTURE_CUBE_MAP_ARRAY , TEXTURE_-
RECTANGLE , one of the targets from table 8.19 (for GetTexImage
and GetnTexImage only), or TEXTURE_CUBE_MAP (for GetTextureImage
only)."
We are currently not validating the target for glGetTextureImage. As
an example, calling this function on a texture with target
GL_TEXTURE_2D_MULTISAMPLE should return INVALID_ENUM, but instead it
hits an assertion down the road in the i965 driver.

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.
