#=======================================================================
# This Makefile was used to make a shared library version of the plotlib
# on Linux. This has not been updated or supported.
#=======================================================================
#================================#
# Makefile for Xplot11 library #
#================================#
#point to your install directory
INSTALLDIR= $(HOME)/lib
#INSTALLDIR= /usr/local/lib
#INSTALLDIR= .
### Use these to set library name
### (add DP to keep double precision version separate)
PLTLIB = libPlt
#PLTLIB = libPltDP
###========================================================
### Basic plot library object files
OBJ = plt_base.o plt_font.o plt_util.o plt_color.o \
set_subs.o gw_subs.o ps_subs.o Xwin.o
OBJMISC =
OBJ3D =
OBJOLD =
###
###--------------------------------------------------------
### Uncomment to add the old plot compatibility routines
OBJOLD = plt_old.o
###
###--------------------------------------------------------
### Uncomment to add the 3D-view routines
OBJ3D = plt_3D.o
###
###--------------------------------------------------------
### Uncomment for f77 compiler w/o AND() and RSHIFT/LSHIFT functions.
### This adds some functions to duplicate these using IAND and ISHFT
### which often appear in these offending fortran's libraries.
### The compilers that this has affected include:
### HPUX f77
### Absoft f77 on Linux
###
#OBJMISC = util-ops.o
###================================================
### Default compilers and flags, install commands
F77 = f77
CC = cc
# Uncomment DP to make double-precision version
#DP = -r8
# Some fortrans need trailing underscores in C interface symbols (see Xwin.c)
DEFINE = -DUNDERSCORE
FFLAGS = -O $(DP)
CFLAGS = -O $(DEFINE)
AR = ar r
RANLIB = ranlib
LINKLIB = -lX11
###-------------------------------------------------------------------------
### Uncomment for Linux, using the script f77 (unusable in Slackware 3.0)
### Note compiler options for Linux:
### f77 script (calls f2c/gcc) note bug in Slackware 3.0 f77 script
### fort77 script (calls f2c/gcc) perl script from RH or from yaf77
### g77 the GNU F77 compiler
F77 = g77
#F77 = fort77
#F77 = f77-f2c
CC = gcc
# Uncomment DP to make double-precision version
# (note -r8 does not work in g77, use f2c instead)
#DP = -r8
FFLAGS = -O2 $(DP)
CFLAGS = -O2 $(DEFINE)
#AR = ar r
#RANLIB = ranlib
LINKLIB = -L/usr/X11R6/lib -lX11
###-------------------------------------------------------------------------
### Basic make targets - build library, test programs
$(PLTLIB): $(OBJ) $(OBJOLD) $(OBJ3D) $(OBJMISC)
$(AR) $(PLTLIB).a $(OBJ) $(OBJOLD) $(OBJ3D) $(OBJMISC)
$(RANLIB) $(PLTLIB).a
test: $(PLTLIB)
(cd examples; make test)
###-------------------------------------------------------------------------
### Utility functions - install the library, clean the directory
install: $(PLTLIB).a
mv $(PLTLIB).a $(INSTALLDIR)
$(RANLIB) $(INSTALLDIR)/$(PLTLIB).a
clean:
-/bin/rm *.o
# -/bin/rm -r PIC
-/bin/rm *.a *.so.*
-/bin/rm plot*.ps
(cd examples; make clean)
###-------------------------------------------------------------------------
### This set of targets makes the libPlt Linux ELF shared library
### As far as I know this only works with g77 as it is the only Linux
### compiler that makes shared libraries.
###
### You will need to install the library in some place that ldconfig knows
### about to get this to work as a shared library.
### 1) Before making the shared library you may need to change the -lf2c
### library reference in the $(PLTLIB).so target below to the shared
### fortran library that you are using (most Linuxes use libf2c, hence
### the -lf2c).
### 2) Install the shared library in some place (like /usr/local/lib).
### 3) Make the following links in that directory
### ln -s libPlt.so.0.21 libPlt.so.0
### ln -s libPlt.so.0 libPlt.so
### 4) Look in /etc/ld.so.conf and check that the library directory is
### in the list of directories and add it if it isn't.
### 5) Then run ldconfig -v (as root) to get the loader to recognize the
### shared library.
$(PLTLIB).so:
mkdir -p PIC
make -f Makefile.linux.shared shared
gcc -shared -Wl,-soname,$(PLTLIB).so.0 -o $(PLTLIB).so.0.21 \
PIC/*.o -lf2c -lm -lc
SHAREDOBJ = $(patsubst %.o,PIC/%.o,$(OBJ) $(OBJOLD) $(OBJ3D) $(OBJMISC))
shared: $(SHAREDOBJ)
###-------------------------------------------------------------------------
