Issue while using new release of GLM (0.9.6.0) : quaternion & align #283

MarkTheFox · 2014-12-04T09:10:54Z

We are updating GLM from 0.9.5.4 (everything went well with #define GLM_FORCE_RADIANS) to 0.9.6.0 and it seems something goes wrong : Here is the message given by Visual 2012:

GLM: Windows platform detected
GLM: Visual C++ compiler detected
GLM: 32 bits model
GLM: C++ with language extensions
GLM: #define GLM_FORCE_CXX98, GLM_FORCE_CXX03, GLM_LANG_CXX11 or GLM_FORCE_CXX1Y to force using a specific version of the C++ language

Other issue appeared : the data won't be aligned if not given as reference ?
le paramètre formel avec __declspec(align('16')) ne sera pas aligné

Thanks in advance,

Hi,

The first issue has been resolved in #282.

The second one... erm, I don't know.

Does current 0.9.6 branch https:/g-truc/glm/archive/0.9.6.zip resolve your issues?

Thanks,
Christophe

MarkTheFox · 2014-12-04T09:33:05Z

Hi,

Thanks for the first issue fix !
But the second one is still present ☹. We will use the 0.9.5.4 and try the 0.9.6.0 on Visual 2013 next.
Best regards,

Marc

I reproduced it: 32 bit issue!
A temporary workaround is to define GLM_FORCE_PURE.
I'll fix it for GLM 0.9.6.1 release.

Thanks,
Christophe

Hi,

Thanks a lot for your quick answers !
Sorry, but I still have an issue while deleting an array of vec4 ☹ :

glm ::vec4 * array = new glm ::vec4[4] ;
delete array ; // <<< this does not work

Maybe that's your fault here, try with delete[] instead. :p

That’s it ! I have made a vector instead since my last email, everything is working now with the FORCE defines.
Thanks a lot.

This issue should be fixed in GLM 0.9.6 branch for GLM 0.9.6.1 release without the need of GLM_FORCE_PURE.

Thanks for reporting,
Christophe

Just wanted to let you know that this is still a problem in glm 0.9.6.1.
Visual Studio 2013 with a 32bit build target.

Groovounet · 2014-12-16T08:48:12Z

Hi,

Can you post what GLM_MESSAGES is giving you?
Also, what are the error messages?

Thanks,

The errors go away when I #define GLM_FORCE_PURE.
Haven't encountered the problem on other platforms or compilers so far.

So I just got latest from the master branch of glm (0.9.7) and I too ran into the alignment issue. I'm compiling with vs2013 november ctp. I compile for both x86 and x64. When I do my compiling I run with /W4, which spit out a lot of warnings about non standard extensions.

warning C4201: nonstandard extension used : nameless struct/union (..\..\source\RenderAL\Color.cpp)

This warning has to do with anonymous structs inside another anonymous struct or union. Whenever this was introduced into the vector types, is when the alignment issue popped up.

Only the x86 architecture is showing errors about alignment. After figuring that out, I commented out the following line in glm/detail/setup.hpp

#define GLM_HAS_ANONYMOUS_UNION !defined(GLM_FORCE_CXX98) && !defined(GLM_FORCE_CXX03) && (GLM_LANG & GLM_LANG_CXXMS_FLAG)

That fixed all the issues. Ill do some digging into why the msvc compiler has alignment issues with that code. Possibly file a bug with microsoft. For now I changed the line to following

#define GLM_HAS_ANONYMOUS_UNION !defined(GLM_FORCE_CXX98) && !defined(GLM_FORCE_CXX03) && (GLM_LANG & GLM_LANG_CXXMS_FLAG) && !(GLM_COMPILER & GLM_COMPILER_VC)

(added '&& !(GLM_COMPILER & GLM_COMPILER_VC' to the end)
Hope this helps some people.

tm4n · 2015-05-14T20:11:37Z

I'm still having the same problem with glm 0.9.6.3 when compiling x86 code with Visual Studio Community 2013:

error C2719: 'mVPMatrix': formal parameter with __declspec(align('16')) won't be aligned

in the code:

virtual void draw(glm::mat4 mVPMatrix);

noizex · 2015-05-14T20:58:08Z

Try passing by reference.

tm4n · 2015-05-14T21:24:50Z

@noizex I can do that as a workaround, but then I get other problems:

warning C4316: 'Mesh' : object allocated on the heap may not be aligned 16

for the object Mesh which has two glm:mat4 members. My code also hits a breakpoint in ntdll on deleting another object with glm::mat4 members. There is still something wrong here.
Linux 32 Bit build with gcc works fine. The glm version I was using before was also fine with visual studio (glm 9.5.x, dont know exactly right now). I also couldn't get GLM_FORCE_PURE to work.

EDIT: cinder/Cinder@56fd399
This fixes the issue for me, including the breakpoint.

noizex · 2015-05-14T21:42:39Z

For classes that use glm's aligned members I just inherit from a special allocator which allows allocating on heap without warnings. It works and does not cause crashes or memory leaks so I think it's okay. Link to that class is here: https://dl.dropboxusercontent.com/u/1040763/aligned_allocator.h. Then:

typedef AlignedAllocator<16> AlignedAllocator16;
class Mesh: public AlignedAllocator16
{
   glm::mat4   foo;
   glm::mat3   bar;
}

That's what I found after some reasearch about aligned members, but treat it with some reserve as I'm not C++ expert :)
