[gmx-users] problem in compiling g_velacc again under gromacs

[Qiao Baofu]

Hi all,

I want to comile the g_velacc again. I copy the original  gmx_velacc.c and
autocorr.c into a new directory, and then comile the gmx_velacc.c, but it
gives the following complains, and then exits. (I didn't change anything in
the two files!!)  How to solve it? Thanks a lot.

**************************************************************************************
/home/fias/qiao/Gromacs//lib/libgmxana.a(autocorr.o)(.text+0x22b0): In
function `low_do_autocorr':
: undefined reference to `xvgropen'

The following are used to compile it:
GMXDIR='/home/fias/qiao/Gromacs/'
INCLUDE="-I${GMXDIR}/include/gromacs -I${GMXDIR}/include/gromacs/types"

LIBS="-L${GMXDIR}/lib -L/usr/X11R6/lib -L/lib -L/usr/lib -L${GMXDIR}/lib"
LDDFLAGS="-lXm -lmd -lm -lgmx -lgmxana -lnsl -lfftw3"
CCFLAGS="-O3"

gcc -g $INCLUDE $CCFLAGS -c gmx_velacc.c
gcc -g $CCFLAGS -o g_velacc  gmx_velacc.o -Wall $LIBS $LDDFLAGS
