Can't compile on 10.7.2

[Alberto Antonini]

I can't compile last version of G3D on 10.7.2
I used this command:
sudo ./buildg3d --install /usr/local update

It get stuck at:
source/TriTree.cpp
../G3D.lib/include/G3D/Array.h: In member function ‘const T&
G3D::Array<T, MIN_ELEMENTS, MIN_BYTES>::operator[](int) const [with T
= G3D::ReferenceCountedPointer<G3D::Surface>, long unsigned int
MIN_ELEMENTS = 10ul, long unsigned int MIN_BYTES = 32ul]’:
../G3D.lib/include/G3D/Array.h:838: internal compiler error:
Segmentation fault: 11

That is gcc crashing, not G3D...so the actual problem it is somewhat out of my hands.  It compiles for me from SVN on 10.7.2 as of this morning.  Maybe you have an out of date version of gcc.

A the command line, try "gcc --version".  I see:

(OS X):~ -> gcc --version

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)

Alberto,

 

I'm interested to find out exactly what gcc version you were building with.

The output of the gcc -version command is the same as yours

I am getting the same error message as the original poster, on OS 1.7.2 and now on 1.7.3 when compiling G3D.  I do appreciate that this is a problem with gcc rather than G3D, but it is driving me mental and any help would be great. My machine is a recent, clean install of OS 1.7, with XCode installed, and the gcc version is

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)

If we can find out what is triggering that internal error, we might be able to adjust the code to get around it.  Unless I can reproduce, all I cn do is search.

Thanks Corey, if there is some additional detail that I can give to help identifying the source of the error then please ask.

A similar compiler issue appears to occur in a number of other projects (e.g. igraph) when using the LLVM based compiler.  I am curious to know if my issues are a result of me performing a clean install of OS Lion rather than an upgrade from 10.6.  If anyone else has managed to get G3D working on a clean install of 10.7 I would appriciate any contact.

One of my least unsuccessful attempts to get G3D working was to install the MACPORT apple-gcc42 and then change the defaultcompiler to g++-apple-4.2 in the .icompile file.  With this the  library now compiles but all sample applications (except computeDiscovery, tinyGlut*, and rawOpenGL) crash on execution with "terminate called throwing an exception"

Can you run the test in GDB and find out what is crashing?

 

The details we would need are what's unique about the code it is crashing on.  I believe you said it was on an Array declaration which might mean the template code is causing it.  I know we use constants for Array sizes in templates which might somehow be an issue.

 

Internal compiler errors are always difficult to debug without the helper of the compiler support team.  Posting that issue to them is the best starting place.
