[GRASS5] nviz compilation with PG support?

Hi again.

to extend the build script to separately compile
NVIZ with PGSQL support, I am currently trying
to compile that. But I get a strange error:

gmake5 src.contrib/GMSL/NVIZ2.2

You need to use "make clean".

GRASS doesn't have accurate dependency information; if you change any
header files or build files (Gmakefiles or src/CMD/generic/*), you
have to manually ensure that anything which needs to be rebuilt does
get rebuilt.

In this case, both of those functions are defined in runInfxQry.c;
however, the whole of that file is conditional upon:

#if defined(HAVE_POSTGRES_H) || defined(HAVE_POSTGRES_FE_H)

Consequently, your runInfxQry.o (from the previous compilation) will
be empty.

You need to use "make clean".

Ah, got it know, it's even easier.

GRASS doesn't have accurate dependency information; if you change any
header files or build files (Gmakefiles or src/CMD/generic/*), you
have to manually ensure that anything which needs to be rebuilt does
get rebuilt.

In this case, both of those functions are defined in runInfxQry.c;
however, the whole of that file is conditional upon:

#if defined(HAVE_POSTGRES_H) || defined(HAVE_POSTGRES_FE_H)

Consequently, your runInfxQry.o (from the previous compilation) will
be empty.

That's it: I was deleting
rm -rf src.contrib/GMSL/NVIZ2.2/OBJ.$ARCH

only and missed:
rm -rf src.contrib/GMSL/NVIZ2.2/src/OBJ.$ARCH

Now it compiles happily.

Thanks,

Markus
