Root (trunk) on mac os x 10.5.2 problem

ROOT
1

Hi,

I am trying to use root on my mac intel. I use the trunk version of root and the system is in version 10.5.2.

I did ./configure macosx64 and I can launch root and use tutorials without problem. But when I try to compile a small project that I developed on Linux, then I get the following error :

make: *** [all] Error 2

I thought maybe I was wrong using the macosx64 architecture. I tried simply macosx and then even root refused to start :

dyld: Library not loaded: /lib/libCint.so
  Referenced from: /local/root/bin/root.exe
  Reason: no suitable image found.  Did find:
	/local/root/lib/libCint.so: mach-o, but wrong architecture
	/local/root/lib/libCint.so: mach-o, but wrong architecture

What am I doing wrong ? Did I miss something ?

Thanks in advance

I tried to link with -m64 flag and it works better. I should have thought about that before.
Nevertheless, I still get one error message about libfreetype :

ld: warning in /usr/local/lib/libfreetype.dylib, file is not of required architecture

So I am still wondering if the macos64 architecture was the correct choice… and how to solve the problem with libfreetype…

Thanks for any help

I recompiled freetype but with -m64 flag (i changed unix-cc.mk) but I am not sure it was the right thing to do . Anyway , now my project compiles without warnings but when I try to launch it I get :

Hi Barth,

if you run on a 10.5 64-bit CPU system then we configure the Mac OS X version for 64 bit. That means that also all your own code should be compiled with -m64. You private /usr/local/lib libfreetype was built for 32 bit (hence the warning). You could link to the ROOT version of freetype which is built for 64 bit. Alternatively you can build ROOT for 32 bit by forcing “macosx” as target in ./configure. Full 64 bit is about 20% faster so worthwhile. To be short make sure your entire chain of libs is either 64 or 32 bit. All Mac system libs are both 32 and 64 bit so they are ok.

Cheers, Fons.

Ok, thanks for the explanation and your help.

I still have crashes as indicated above, but I switched from TRint to TApplication for the time being and it works well.

Thanks
