Suppose you have hello.c
int main() { return 0; }
and Makefile
hello: hello.c
gcc hello.c -o hello
install: hello
install -m 755 hello /usr/bin/
The quickest and easiest way to get binary package seems to be to use checkinstall:
fakeroot checkinstall --pkgname hello -y -D --install=no --backup --nodoc --fstrans --pkgversion 0.0.1 make install
How to do similar thing, but for source package (to put it to some source repository or use "dpkg-buildpackage" on it)?
The officicial text is rather long: orig.tar.gz, changelog, control file... Is there something like checkinstall, but for source packages? Additional bonus whould be if it also figures out dependencies automatically (at least partially).

Below archive file(shuffler.a) is created with below command:
$ go install github.com/myhub/cs61a
$
$
$ file pkg/linux_amd64/github.com/myhub/cs61a/shuffler.a
pkg/linux_amd64/github.com/myhub/cs61a/shuffler.a: current ar archive
$
$
But there is more than one than file(relocatable) integrated in archive file:
$ ar -t pkg/linux_amd64/github.com/myhub/cs61a/shuffler.a
__.PKGDEF
_go_.o
$
$
_go_.o is a relocatable binary form of src/github.com/myhub/cs61a/shuffler/shuffle.go source code
What does __.PKGDEF signify? ar –rcs libourown.c one.o two.o in C world does not add this file
Since go code is organized by package, while C code is not, and since go libraries/binaries are compiled package by package, I would take the wild guess that PKGDEF has information about the go language package from which the code was compiled.
What I have done:
git clone https://github.com/eclipse/paho.mqtt.c
cd paho.mqtt.c
make
sudo make install
Then, I tried compiling a simple C program that includes the MQTT C library like this:
#include <MQTTClient.h>
The command I used was:
$ gcc -o mqttTest mqttTest.c -lpaho-mqtt3c
What I got was ...
... even though the libraries are clearly present in /usr/local/lib:
What do I need to do to compile my code?
I already tried adding -L/usr/local/lib to the compile command, to no avail.
I found the answer on GitHub. See VilleViktor's post here: https://github.com/eclipse/paho.mqtt.cpp/issues/150
All I had to do was:
$ mv /usr/local/lib/libpaho-mqtt3a.so.1.0 /usr/local/lib/libpaho-mqtt3a.so.1
$ mv /usr/local/lib/libpaho-mqtt3as.so.1.0 /usr/local/lib/libpaho-mqtt3as.so.1
$ mv /usr/local/lib/libpaho-mqtt3c.so.1.0 /usr/local/lib/libpaho-mqtt3c.so.1
$ mv /usr/local/lib/libpaho-mqtt3cs.so.1.0 /usr/local/lib/libpaho-mqtt3cs.so.1
Maybe that saves someone else a lot of time on Google ...
i have MOTIF installed X11
a easy program is saved as hello.c
there is the following message
where can i get the X11/intrinsic.h , file ???
need help to compile
my system : MX-16 Linux Debian Jessie / i386
Code:
hans#mx1:~/Documents
$ cc push.c -o push -lXm -lXt -lX11
In file included from push.c:2:0:
/usr/include/Xm/Xm.h:59:27: fatal error: X11/Intrinsic.h: No such file or directory
#include <X11/Intrinsic.h>
^
compilation terminated.
hans#mx1:~/Documents
I installed the libxt-dev package on my Debian box:
apt-get install libxt-dev
Then the proper header will be installed:
# find /usr -name "Intrinsic.h" -print
/usr/include/X11/Intrinsic.h
Been using xv for several decades now -- I always find myself trying to rebuild it.
The copy on my system came from libxt-dev
$ locate Intrinsic
/usr/include/X11/Intrinsic.h
/usr/include/X11/IntrinsicI.h
/usr/include/X11/IntrinsicP.h
$ dpkg-query -S /usr/include/X11/Intrinsic.h
libxt-dev:amd64: /usr/include/X11/Intrinsic.h
You may want to install and use apt-file - you can ask it for a filename and it will tell you which packages (that you don't even have to have installed - just from the repos in your sources.lists) contain a file with that name
I would like to link readline statically with my program and I found this page about readline compilation from source http://www.bioinf.org.uk/software/profit/doc/node17.html but I'm a bit confused about the process.
The page talks about a variable READLINELIB in the makefile but I don't find it.
Could someone show me the way to use readline statically in my program, what to put in my Makefile for compiling readline from source and link it with my program?
Thank you.
Finally I figured out the proper way to do it, I using the --prefix option of the configure file I can tell where to put/install the library. The problem about installation was that I don't have the right to access other directories than my $HOME, so no problem doing this:
configure --prefix=$HOME/libreadline && make && make install-static
Then in my program I include the file from $HOME/libreadline/include.
To compile the main program I link the program with the archive libraries $HOME/libreadline/lib/libreadline.a and $HOME/libreadline/lib/libhistory.a.
Also since readline files uses directive like #include <readline/readline.h> which doesn't correspond to the location of the files, I must tell the compiler where to look for included files. To do this, before running gcc, I set the variable C_INCLUDE_PATH to $HOME/libreadline/include.
Finally, since readline uses ncurses dynamic library I must tell the compiler to dynamically link it with my program. It might be the case of termcap too...
The overall process looks like:
configure --prefix=$HOME/libreadline && make && make install-static
export C_INCLUDE_PATH=$HOME/libreadline/include
gcc -o myprogram myprogram.c $HOME/libreadline/lib/libreadline.a $HOME/libreadline/libhistory.a -lncurses -ltermcap
I was confused about what make install do, it only copy files to the location provided by the configure, by default it installs in system directories like /usr/include, etc... but providing the --prefix option make install will copy all files in the specified directory.
Installation is just copying compiled program, libraries, doc, etc to a certain location, by default standart system directories, if you don't have access to those directories like me you could "install" it in your own directory and then do whatever you wan't with it.
I could have installed the dynamic library instead the static one, but then I would have to modify the LD_LIBRARY_PATH environment.
get readline source
wget http://git.savannah.gnu.org/cgit/readline.git/snapshot/readline-master.tar.gz
tar zxvf readline-master.tar.gz
cd readline-master/
examples folder does not have Makefile, which is generated using Makefile.in script.
following steps build static & dynamic libs & puts them inside /usr/local/bin
./configure
make
sudo make install
may have to install curses as "sudo apt-get install libncurses5-dev"
Use following make file (strip down version from examples folder)
(Make sure tab is honored otherwise makefile will not work)
RM = rm -f
CC = gcc
CFLAGS = -g -O
INCLUDES = -I/usr/local/include
LDFLAGS = -g -L/usr/local/lib
READLINE_LIB = -lreadline
TERMCAP_LIB = -ltermcap
.c.o:
${RM} $#
$(CC) $(CFLAGS) $(INCLUDES) -c $<
SOURCES = rlversion.c
EXECUTABLES = rlversion
OBJECTS = rlversion.o
all: $(EXECUTABLES)
everything: all
rlversion: rlversion.o
$(CC) $(LDFLAGS) -o $# rlversion.o $(READLINE_LIB) $(TERMCAP_LIB)

I was in need of libraries libreadline.a, libhistory.a for both 64 and 32 bit versions.
The answer provided by Rajeev Kumar worked for me. ( Had a little trouble finding and installing libncurses).
For 32-bit versions, using https://packages.ubuntu.com/search?keywords=lib32readline-dev, the following command worked for me.
sudo apt install lib32readline-dev
So it is hoped that for 64 also, it works
sudo apt install libreadline-dev
I am trying to use libjpeg to decompress a jpeg contained in a memory block into its RGB values. I originally had version 6.2 on my system, but I needed the function jpeg_mem_src so I upgraded to 8d. I use the follow commands to install/configure:
./configure
sudo make clean
sudo make
sudo make uninstall
sudo make install
And to compile my program I use (discounting the commands to remove .o files and recompile them):
g++ main.o googlestreetview.o -lopencv_core -lopencv_highgui -lcurl -ltinyxml2 -ljpeg -o example
However when running this code:
struct jpeg_decompress_struct cinfo;
struct jpeg_error_mgr jerr;
cinfo.err = jpeg_std_error( &jerr );
jpeg_create_decompress(&cinfo);
I simply get: "Wrong JPEG library version: library is 62, caller expects 80"
This seems strange, because I have not only manually removed libjpeg from my system, but I've recompiled 8d and installed it a number of times. What steps can I take to resolve this?
try
./configure --with-jpeg8
before to recompile it.
