Dear All,
I have been following the discussions on optimizing and re-compiling the
SPM mex routines for faster running. I have run in a number of
problems, mainly related to my local configuration I suspect. In
particular, the linking stage is issuing many, many errors of the
following type:
mex -f ./mexopts.sh spm_sample_vol.c spm_vol_utils.mexsol.a
Text relocation remains referenced
against symbol offset in file
<unknown> 0x94
spm_vol_utils.mexsol.a(spm_vol_access.mexsol.o)
<unknown> 0xa0
spm_vol_utils.mexsol.a(spm_vol_access.mexsol.o)
<unknown> 0x5f0
spm_vol_utils.mexsol.a(spm_vol_access.mexsol.o)
<unknown> 0x5fc
spm_vol_utils.mexsol.a(spm_vol_access.mexsol.o)
<unknown> 0xbac
spm_vol_utils.mexsol.a(spm_vol_access.mexsol.o)
The system is Matlab 7.01 running on SunSPARC with Solaris9 and gcc 3.3.2.
If I do mex -n to see what commands are being issued to gcc I get the
following:
bash-2.05# mex -n -f ./mexopts.sh spm_sample_vol.c
spm_vol_utils.mexsol.a
-> gcc -c -I/usr/local/matlab7p1/extern/include

-L/usr/local/matlab7p1/bin/sol2 -lg2c -lmx -lmex -lmat -lm -lm
This includes all the suggested extra library paths I found by Google
searching. If anyone has any extra hints, please could they point me in
the right direction.
Many thanks in advance,
Mark
