Subject:	Makefiles to create a library based on Asyn
From:	Benoit <[email protected]>

Hi everybody,

I am creating a "generic" library in order to connect several open hardware FPGA devices to EPICS.

This library is able to handle different bridges (syncronous => PCIe & asynchronous => etherbone, serial) so I have based it on asyn.

But I am having trouble to create the Makefile system in order to generate my libewb.so

EPICS_BASE = 3.1.4

Asyn =4.13.1

make -C ./configure install
make[1]: Entering directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/configure'
make -C O.linux-x86 -f ../Makefile TOP=../.. T_A=linux-x86 install
make[2]: Entering directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/configure/O.linux-x86'

make[1]: Leaving directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/configure'
make -C ./src install
make[1]: Entering directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/src'
make -C O.linux-x86 -f ../Makefile TOP=../.. T_A=linux-x86 install
make[2]: Entering directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/src/O.linux-x86'
Installing os dependent include file ../../include/os/Linux/.
Usage:

-m mode Set the mode for the installed file (0755 by default)
file Name of file

make[2]: *** [../../include/os/Linux/.] Error 2
make[2]: Leaving directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/src/O.linux-x86'

When I print more info in the Makefile I have:

make[2]: Entering directory `/home/neub/Work/7S/LLRF/LOCAL/epics-wb/src/O.linux-x86'
echo "Installing os dependent include file ../../include/os/Linux/."
perl /opt/EPICS/base/bin/linux-x86/installEpics.pl -d -m 644 . ../../include/os/Linux

It seems that we are trying to add the file '.' but I don't know why?

my Makefile is as follow:

TOP = ..
include $(TOP)/configure/CONFIG
### Obtain the version ($ is replaced by $$)
VERSION = $(shell git describe --always --dirty=+ | sed 's;^.*-$[v0-9\.]*$$[a-z0-9\-+]*$$$;\1\2;' )
DATE = $(shell date +"%d %b. %Y")

### Create the user FLAGS
#USR_CFLAGS += -DDEBUG
CXXFLAGS=-Wall -g -DTRACE_STDERR -std=c++11
USR_CXXFLAGS +=${USR_FLAGS}
USR_CXXFLAGS +=${CXXFLAGS}
USR_CXXFLAGS +=-D__GIT_VER__="\"${GIT_VER}\""

EWB = $(TOP)/src
### Define the library
LIBRARY = ewb
ewb_LIBS += $(EPICS_BASE_IOC_LIBS)
ewb_LIBS += asyn

### Process ewb_core
CORE_SRC_DIR = $(EWB)/ewbcore
CORE_INC +=$(wildcard $(CORE_SRC_DIR)/*.h)
CORE_SRCS +=$(wildcard $(CORE_SRC_DIR)/*.cpp)
CORE_OBJS += $(addprefix $(ODIR), $(subst $(EWB)/,,$(CORE_SRCS:.cpp=.o)))
### Process ewb_bridge
BRIDGE_SRC_DIR = $(EWB)/ewbbridge
BRIDGE_INC +=$(BRIDGE_SRC_DIR)/EWBBridge.h
BRIDGE_INC +=$(BRIDGE_SRC_DIR)/EWBMemTestFileCon.h
BRIDGE_SRCS +=$(BRIDGE_SRC_DIR)/EWBMemTestFileCon.cpp

### Add external library for bridge
ifeq (${JUNGOWD_OFF},1)
USR_CXXFLAGS +=-DAWBPD_NO_X1052
else
BRIDGE_INC +=$(BRIDGE_SRC_DIR)/EWBMemTestFileCon.h
BRIDGE_SRCS +=$(BRIDGE_SRC_DIR)/EWBMemTestFileCon.cpp
USR_INCLUDES +=-I${JUNGOWD} -I${JUNGOWD}/include
USR_INCLUDES +=-I${X1052} -I${X1052}/include
USR_SYS_LIBS += x1052_api
USR_SYS_LIBS += wdapi${JUNGOWDVER}
endif

### Append to the list
SRC_DIRS += $(CORE_SRC_DIR)
INC += $(CORE_INC)
ewb_SRCS += $(CORE_SRCS)
SRC_DIRS += $(BRIDGE_SRC_DIR)
INC += $(BRIDGE_INC)
ewb_SRCS += $(BRIDGE_SRCS)
