[xmlvm-users] XMLVM produced code does not compile with current Xcode

[Panayotis K. <pan...@pa...>]

I have just updated to Xcode 4.2 (the current Xcode version, compatible with iOS 5), and I found that the produced code (in C and obj-c) is not compilable any more.
THe problem is with an object defined as a @class, and later on redefined using the typedef notation.

After some experimentation, it seems that this is an issue with GCC& Clang.
For some reason, Clang is more strict on this issue, while GCC is not.
At least for the ObjC backend, if I change the compiler form Clang to GCC solved this issue.
With C backend though I was not equally lucky (but I have to admit I didn't dig more into it).

a minimalistic sample app that reproduces the problem would help.

Any app, unfortunately.

I will partially address the issue, by setting "by default" the GCC compiler instead of the "default apple compiler" (which is Clang).
But I believe to be future proof, it would be better to look how to make the C code compatible with Clang...

I just committed a patch that selected GCC 4.2 as the default compiler (overriding Apple's default settings).
Although more or less works now, I think it is important to address this issue anyway.
