[MINC-users] Linker errors on OS X Tiger when compiling ITK MINC2ImageIO

[Thomas Mansi]

Dear all,

I would like to test the MINC IO factory of ITK but I am experiencing  
some linking problems when compiling the tools.

I am on Mac OS X Tiger (32bits), HDF5 v 1.6.1 and here is what I did  
so far.

+ I successfully compiled and installed netcdf 1.6.2 with -fno-common  
option

+ I successfully compiled minc 2.0.15 without -fno-common option.  
With -fno-common, I have the following linker error:

/bin/sh ./libtool --tag=CC   --mode=link gcc  -fno-common   -o  
minctoecat conversion/minctoecat/minctoecat.o conversion/minctoecat/ 
ecat_write.o conversion/minctoecat/machine_indep.o libvolume_io2.la

(__DATA,__common)conversion/minctoecat/machine_indep.o definition of  
_matrix_errtxt in section (__DATA,__common)collect2: ld returned 1  
exit status


+ I then compile a CVS version of ITK. I enabled MINC2 support as  
well as ITK_USE_REVIEW to compile the itkMINC2ImageIO files. But then  
I get these linker errors (with or without -fno-common option):

Do you have any idea about these issues? Have I missed something in  
the installation procedure of MINC2?

Thank you in advance for your precious help!
