I need to make static hubbub library files for x32 and x64 platforms. Options like -m32/64 don't work, maybe I need to specify TARGET properly, but I don't know what to write here. What should I do?
Here is the makefile of the lib:
# Component settings
COMPONENT := hubbub
COMPONENT_VERSION := 0.2.0
# Default to a static library
COMPONENT_TYPE ?= lib-static
# Setup the tooling
PREFIX ?= /opt/netsurf

# BeOS/Haiku/AmigaOS have standard library errors that issue warnings.
ifneq ($(TARGET),beos)
ifneq ($(TARGET),amiga)
WARNFLAGS := $(WARNFLAGS) -Werror
endif
endif
CFLAGS := -D_BSD_SOURCE -I$(CURDIR)/include/ \
-I$(CURDIR)/src $(WARNFLAGS) $(CFLAGS)
ifneq ($(GCCVER),2)

endif

ifneq ($(PKGCONFIG),)
CFLAGS := $(CFLAGS) $(shell $(PKGCONFIG) libparserutils --cflags)
LDFLAGS :=$(LDFLAGS) $(shell $(PKGCONFIG) libparserutils --libs)
else
CFLAGS := $(CFLAGS) -I$(PREFIX)/include
LDFLAGS := $(LDFLAGS) -lparserutils
endif
endif
include $(NSBUILD)/Makefile.top
ifeq ($(WANT_TEST),yes)
# We require the presence of libjson -- http://oss.metaparadigm.com/json-c/
ifneq ($(PKGCONFIG),)
TESTCFLAGS := $(TESTCFLAGS) \
$(shell $(PKGCONFIG) $(PKGCONFIGFLAGS) --cflags json)
TESTLDFLAGS := $(TESTLDFLAGS) \
$(shell $(PKGCONFIG) $(PKGCONFIGFLAGS) --libs json)
else
TESTCFLAGS := $(TESTCFLAGS) -I$(PREFIX)/include/json
TESTLDFLAGS := $(TESTLDFLAGS) -ljson
endif
ifneq ($(GCCVER),2)
TESTCFLAGS := $(TESTCFLAGS) -Wno-unused-parameter
endif
endif
# Extra installation rules
I := /include/hubbub
INSTALL_ITEMS := $(INSTALL_ITEMS) $(I):include/hubbub/errors.h
INSTALL_ITEMS := $(INSTALL_ITEMS) $(I):include/hubbub/functypes.h
INSTALL_ITEMS := $(INSTALL_ITEMS) $(I):include/hubbub/hubbub.h

INSTALL_ITEMS := $(INSTALL_ITEMS) /lib/pkgconfig:lib$(COMPONENT).pc.in
INSTALL_ITEMS := $(INSTALL_ITEMS) /lib:$(OUTPUT)
You also can download it:
git clone git://git.netsurf-browser.org/libhubbub.git
Just use this:
$ make TARGET=amd64
or
$ make TARGET=i386

I am trying to create a makefile to control the build process. I use eclipse and I have a lot of projects some of which are shared libraries. So if I build a project that is using a library, then I would like the library to be built if it is out of date. The seems pretty standard. I just cannot make it work.
I am making the linking dependent on the libraries, and I (try to) provide a rule for building the libraries. But when I do it this way, it seems to be building the library over and over again - and it never finishes. What am I missing?

In my makefile I want to include some other makefile depending on a variable in a for loop, Is it possible.
Top Makefile :
CC = gcc
CFLAGS = -O0 -g3 -W -Wall -pedantic
LDFLAGS =
DEFINES =
PROJECT = proj
INCLUDES =
SOURCES =
TEMP_PATH := $(PROJECT)
include $(TEMP_PATH)/Makefile
$(for blocks in $(BLOCKS); do \
include $$(blocks)/Makefile; \
done)
all : $(PROJECT).exe
$(PROJECT).exe :
$(CC) $(CFLAGS) $(LDFLAGS) $(DEFINES) $(INCLUDES) $(SOURCES) -o $#
clean :
rm -rf *.exe
proj/Makefile :
CC = gcc
CFLAGS = -O0 -g3 -W -Wall -pedantic
LDFLAGS =
DEFINES =
BLOCKS := std_communication
INCLUDES := $(INCLUDES) -I $(TEMP_PATH)/Utils
INCLUDES := $(INCLUDES) -I $(TEMP_PATH)/Communication
SOURCES := $(SOURCES) $(wildcard $(TEMP_PATH)/Utils/*.c)
SOURCES := $(SOURCES) $(wildcard $(TEMP_PATH)/Communication/*.c)
SOURCES := $(SOURCES) $(wildcard $(TEMP_PATH)/main.c)
The for loop syntax seems to be wrong outside of loop.
You cannot write it like that, but you can just write:
include $(addsuffix /Makefile,$(BLOCKS))
I am writing makefile by example of another and have stumbled upon this target rule:
ifeq ($(MAKECMDGOALS),build_executable)
$(firstword $(dependency_files)): $(application_path)/config/gcc/app.mk
#rm -rf $(object_output_path)
-include $(dependency_files)
endif
This is placed between other rules. This makefile runs recursively reinvoking itself with different goals.
All variables pretty much explains themself. Prerequisite app.mk contains just configuration by some variables set which are used in this make file. Dependency files variable constructed like this:
dependency_files := $(object_files:%.o=%.d)
My question is what "common practice" this rule corresponds to, what does it do and why it is like that. If my understanding is correct (please correct me if I am wrong), I do understand that first of all it includes all dependency files if they exist. Then this rule may be ran by "makeflow". What I do not understand is the intention of doing this. Also, what is the trigger of running this rule on that one (basically the random one) dependency file since .d files are generated with GCC -MMD -MP options.
Thanks in advance.

Changing the app.mk file might make the dependency files obsolete. What this rule does is forcing the re-building of the dependency files by deleting their directory.
For instance the dependencies may change because preprocessor symboles where added or modified. Let's assume that in the provided example the c_compiler_options has been modified to add the -DUSE_FLOATING_POINT option:
c_compiler_options += -DST -DSTM32F469xx -DUSE_OS_SYSTICK -DUSE_FLOATING_POINT -g -gdwarf-2
In a source file this may add or remove include file directives:
#ifdef USE_FLOATING_POINT
#include <some_file.h>
#else
#incude <anotherfile.h>
#endif
Hence the need for running the dependendy evaluation again.
I'm running Arch Linux and have installed the cuda-sdk and cuda-toolkit from the repositories. I've compiled the libraries inside /opt/cuda-sdk/CUDALibraries fine.

# The following definition is a template that gets instantiated for each SM
# version (sm_10, sm_13, etc.) stored in SMVERSIONS. It does 2 things:
# 1. It adds to OBJS a .cu_sm_XX.o for each .cu file it finds in CUFILES_sm_XX.
# 2. It generates a rule for building .cu_sm_XX.o files from the corresponding
# .cu file.
#
# The intended use for this is to allow Makefiles that use common.mk to compile
# files to different Compute Capability targets (aka SM arch version). To do
# so, in the Makefile, list files for each SM arch separately, like so:
# This will be used over the default rule abov

I have checked for libcuda and can find it where I think it should be:
# ls /usr/lib | grep libcuda
libcuda.so.1
libcuda.so.304.32
Is there something obvious I need to do to get these to compile? Is this a problem with the CUDA makefile or with my system?
The answer was suggested in comments, and the OP found the solution:
I added a symlink:
ln -s /usr/lib/libcuda.so.1 /usr/lib/libcuda.so
and it compiled fine.
So, this is odd. In my makefile I have
CC:=icc
ifeq ($(CC),icc)
CFLAGS := $(ICCFLAGS)
LIBS := $(LIBS) -openmp
else
CFLAGS := $(GCCFLAGS)
LIBS := $(LIBS) -fopenmp
endif
for make, the condition is false but
CCC:=icc
ifeq ($(CCC),icc)
CFLAGS := $(ICCFLAGS)
LIBS := $(LIBS) -openmp
else
CFLAGS := $(GCCFLAGS)
LIBS := $(LIBS) -fopenmp
endif
here the condition is true, and
CC:=icc
CCC:=$(CC)
ifeq ($(CCC),icc)
CFLAGS := $(ICCFLAGS)
LIBS := $(LIBS) -openmp
else
CFLAGS := $(GCCFLAGS)
LIBS := $(LIBS) -fopenmp
endif
here the condition is false again. What the hell is going on?
It seem that you're either passing CC as a command line option, like:
make CC=...
... or invoking make with -e switch, which forces environment variables to take precedence over the ones defined in Makefile.
You can use origin function to check how the variable has been defined:
CC := icc
$(error CC comes from $(origin CC))
If this prints command line or environment override, then the solution is to use override directive:
override CC := icc
This will set CC variable even if there is another one from command line or environment.
