cal3d CalCore* errors when compiling

[Aislinn]

I've been trying to compile for about a week now and just can't get past the cal3d errors.  I don't know if it's an easy fix for an include that wasn't included, or if my cal3d is malfunctioning.   Any input appreciated.

Hmm, I guess we can't use code option anymore.  At least I can't find it.

I'm seeing identical errors while trying to compile for macOS:

Undefined symbols for architecture i386:

Is this on Arch Aislinn? What version of cal3d library are you using? Ben, your errors look different how are you compiling?

I'm using Xcode, the usual method for the macOS client.

I'm so sorry, I thought my specs were in my signature and they're not.  Yes, this is on Arch.  My cal3d version is 0.11.0, release 6.

[bluap]

I have an Arch install that I use now and again.  That clean compiles and is using the same cal3d version.  I'm in the process of updating the packages so I'll see what happens after that is done.

 

[bluap]

Well after a full update and reboot, and rebuild.  It all compiles fine on my Arch box with a minor warning in Achievements.cpp. 

What is your GCC version? (gcc -v)

Just guessing here, but when did you last recompile the cal3d package.  It could be the cxx abi changes are the problem.  Assuming you are using AUR, can recompile and reinstall cal3d?

[Aislinn]

gcc version 8.1.0 (GCC) 

 

Yes, I use AUR, I'll recompile and reinstall and will report what happens.  Thank you for looking into this!

[Aislinn]

Well, this is not going well.  The package in AUR is empty.  So trying to use an outside download here and will need to install with Makefile instead of makepkg and pacman.  

 

So first round of errors give me many that look like this:

hardwaremodel.cpp:754:3: error: ‘memcpy’ was not declared in this scope
   memcpy(&m_pVertexBuffer[(hardwareMesh.baseVertexIndex+i)*m_vertexStride],&vectorVertex[indice].position,sizeof(CalVector));
   ^~~~~~
hardwaremodel.cpp:754:3: note: ‘memcpy’ is defined in header ‘<cstring>’; did you forget to ‘#include <cstring>’?

So I added #include <cstring> to hardwaremodel.cpp and ran make again.  That seemed to fix that problem.  I ran make again.

 

That brought me to many errors like this:

loader.cpp: In static member function ‘static CalCoreKeyframe* CalLoader::loadCoreKeyframe(CalDataSource&)’:
loader.cpp:889:12: error: cannot convert ‘bool’ to ‘CalCoreKeyframe*’ in return
     return false;
            ^~~~~
loader.cpp: In static member function ‘static CalCoreSkeletonPtr CalLoader::loadXmlCoreSkeleton(const string&)’:
loader.cpp:1341:11: error: could not convert ‘false’ from ‘bool’ to ‘CalCoreSkeletonPtr’ {aka ‘cal3d::RefPtr<CalCoreSkeleton>’}
    return false;
loader.cpp:1347:11: error: could not convert ‘false’ from ‘bool’ to ‘CalCoreSkeletonPtr’ {aka ‘cal3d::RefPtr<CalCoreSkeleton>’}
    return false;
           ^~~~~
loader.cpp:1356:10: error: could not convert ‘false’ from ‘bool’ to ‘CalCoreSkeletonPtr’ {aka ‘cal3d::RefPtr<CalCoreSkeleton>’}
   return false;
          ^~~~~

 

And now I'm stuck.

Hmm.  I did a clean build of the AUR package I already had built and I get those same errors about false to bool (not the memcpy which is probably sorted by the AUR config script).  I've not got time now but you could try replacing false with 0, as its actually a pointer value I think.  Otherwise, I'll see if I can get it working when I get home tonight.

[bluap]

I could not resist check, the false -> 0 works.

Here's a very hacked AUR package tree that includes the missing download and patch file.  I'll do a proper patch later.

I built and installed this with "makepkg -sri -f"

[revi]

You might have a problem with the C++ language version used:
G++ 8.1 uses the 2014 standard of C++, and one of the things that changed there is pointer comparisons and conversions.
In this case, the funtions return "0" on error, and should return "nullptr" (or throw an exception).

 

Try using "-std=c++98", "-std=c++03", or "-std=c++11" when compiling the library (and possibly the client!)

So far, cal3d compiled successfully with your fix, bluap.  Will try the client again. 

 

Whoa,  hallelujah, it works!  Client compiled and I'm on it.  Thank you SO much! 

[bluap]

Good news, I'm glad its working.  I'll see if I can submit a patch to get the AUR updated.
