here is my make command

g++ -I/usr/lib/grass64/include grass.o -L/usr/lib/grass64/lib

and you are trying to build against the installed grass 6.4 not a self-
built but uninstalled 6.5svn or other version, right?

libgrass_gis is there but still error/home/rashad/grass.cpp:5:
undefined reference to `G__gisinit(char const*, char const*)'

please try that.

as root:

echo /usr/lib/grass64/lib >> /etc/ld.so.conf
ldconfig

maybe add the grass lib dir to your /etc/ld.so.conf file, then
as root run ldconfig. then the grass libs will be in the library
search path.

please try that.

as root:

echo /usr/lib/grass64/lib >> /etc/ld.so.conf
ldconfig

Hi Hamish
I tried that but no luck :frowning:

Hi Hamish
I tried that but no luck :frowning:

That was not Martin's question. Martin asked if the GRASS libraries
are really installed in `usr/lib/grass64`. By default, after `make
install`, libraries are installed in `$prefix/grass-6.4.2svn/lib`,
prefix would be `usr/local`on default. Please check again the
directory `$prefix/grass-6.4.2svn/lib`, optionally replacing $prefix
with your choice of prefix.

I installed grass from source it is installed on /usr/local/.grass-6.4.2svn

i also installed from lucid repos it is installed on /usr/lib/grass64

so there are two installations. I also tried to link with each sepreately and add one by one to /etc/ld.so.cinbf
and do ldconfig

but still error

As my title indicates there is one more question GRASS && OpenCV. Is there any need for it. If yes please tell me…
