Series of problems in compiling a source file (FLENS)

[mohabic]

Dear ALL:-
please help me, i spent more than month trying to install this FLENS, please guide me, im incredibly new to ubuntu.i'm in need of installing flens.

that is what i did to install flens
i installed the dependencies by this line, (blas and lapack packages names were changed, thanks to Paul)
moha at ubuntu:~/FLENS-2009-06-12$ sudo apt-get install libatlas-base-dev liblapack-pic libblas-dev

then i changed the config file to be like that
--------------------------
CXX = g++
CXXFLAGS += -Wall -Wextra -Werror -g -O0 -fPIC
INCDIRS += -I.
DYLIB_EXT = so
CXXDYLIB = -shared
LDFLAGS += -libatlas-base-dev -liblapack-pic -libblas-dev
--------------------------
do i have to change anything in it ??

when i tried to ./configure, that is what got
moha at ubuntu:~/FLENS-2009-06-12$ ./configure
bash: ./configure: No such file or directory
<put in my mind that i have only one folder called config in the FLENS-2009-06-12 folder>

when i tried to excute this line in terminal, i got no responce
export LD_LIBRARY_PATH=/home/moha/FLENS-2009-06-12:$LD_LIBRARY_PATH
i also added the slash before colon
export LD_LIBRARY_PATH=/home/moha/FLENS-2009-06-12:$LD_LIBRARY_PATH
and the terminal just do this
moha at ubuntu:~/FLENS-2009-06-12$ export LD_LIBRARY_PATH=/home/moha/FLENS-2009-06-12:$LD_LIBRARY_PATH
moha at ubuntu:~/FLENS-2009-06-12$

what is the problem ?!

i succeded to "make" the file
i got no errors ,
somebody told me that i have to "./config" first , but when i wrote that at terminal, that is what i got
moha at ubuntu:~/FLENS-2009-06-12$ ./config
bash: ./config: Permission denied
moha at ubuntu:~/FLENS-2009-06-12$ sudo ./config
sudo: ./config: command not found

now i cant "make install"
im incredibly confused,
what should i do ?

Thanks on advance

Did you read the installation instructions at the FLENS web site?

FLENS - Obtain

It says to run the config file that matches your distro. When I ran it on Ubuntu 9.04, all I got is errors. I didn't install any of the needed prerequisites either.

$ ./config.ubuntu
./config.ubuntu: line 1: CXX: command not found
./config.ubuntu: line 2: CXXFLAGS: command not found
./config.ubuntu: line 3: INCDIRS: command not found
./config.ubuntu: line 4: DYLIB_EXT: command not found
./config.ubuntu: line 5: CXXDYLIB: command not found
./config.ubuntu: line 6: LDFLAGS: command not found

Running it withsudo changed the error, slightly.

$ sudo ./config.ubuntu
[sudo] password for paul: 
./config.ubuntu: 1: CXX: not found
./config.ubuntu: 2: CXXFLAGS: not found
./config.ubuntu: 3: INCDIRS: not found
./config.ubuntu: 4: DYLIB_EXT: not found
./config.ubuntu: 5: CXXDYLIB: not found
./config.ubuntu: 6: LDFLAGS: not found

What do you get? You may need to customize the config.ubuntu file to show the correct info.

[waterhead]

OK, I think that I have made some progress for you. I installed the prerequisites first, so that I can test it for you.

I then found that the config.ubuntu file is not a script to be run. You should make any changes to it that you think you need (I left it as is), then save it as config (without the .ubuntu suffix). Then just run the make command.

I did this, and it is now compiling on my little Eee PC

Edit:
By the way, these are the packages that I install before compiling.

libatlas-base-dev (3.6.0-22ubuntu2)
libatlas-headers (3.6.0-22ubuntu2)
libatlas3gf-base (3.6.0-22ubuntu2)
libblas-dev (1.2-2)
liblapack-dev (3.1.1-6)
liblapack-pic (3.1.1-6)

[waterhead]

Now that I have compiled it, installing it gives me errors similar to yours:

$ sudo make install
[sudo] password for paul: 
Makefile.common:19: /config: No such file or directory
make: *** No rule to make target `/config'.  Stop.

And running ./config gives me the same errors as before, as it isn't suppose to be run like a script. I looked at the file/line that it was complaining about: Makefile.common:19. It is a path, so I replaced it with the path to the folder where I am compiling FLENS, but left the /config at the end. Then when I ran sudo make install I got this:

$ sudo make install
make: `install' is up to date.

That's not an error, but is FLENS installed? I guess that I really haven't been much help.

Dear Paul
I'm really thankful to you, really really thankful to your help.
I could solve the problem with this
sudo checkinstall
it made .deb file and installed fortunatelly :d
but the question now is, Is flens really installed ?
(make is done without changing makfile.common)
this is the terminal o/p:-

Thank you Paul.

Is it possible that flens is not a program, but a library?

I have already deleted my flens folder, but I did notice that it created a libflens.so file. This is a shared library file, so that is why I thought that.

[waterhead]

I found some info that suggests that you need to copy the libflens.so file to a folder that is in the LD_LIBRARY_PATH. This means a folder like /usr/lib.

yes, it;s a Library, and this lne is suposed to be executed, but i dont understand
export LD_LIBRARY_PATH=/home/moha/FLENS-2009-06-12:$LD_LIBRARY_PATH

but i also get no responce
what should i do ?
Thanks

[waterhead]

LD_LIBRARY_PATH = specifies where the computer looks for dynamically-loaded libraries

I don't know if it actually copies the library, or just stores a link to it. The link files would be found in the /etc/ld.so.conf.d/ folder. I see that I don't have anything for flens, so it didn't work for me.

You can manually create the link, but first you may need to copy the libflens.so file to the correct folder. I think that /usr/lib/ is the correct place for it. In fact, if you put it there I don't believe you need to register the path.

In retrospect, that may not be the correct way to go about this. You may want to keep it in the folder that it was created in. This way it has access to the other files in that folder. Then create a file for it named libflens.conf containing the path to it. Put that file in the /etc/ld.so.conf.d folder. Then update everything, with this command.

sudo ldconfig

I hope this fixes everything. Ubuntu does things a little differently. The old way was to put the path in the /etc/ld.so.conf file, then run ldconfig to update everything. You may still need to do that, so that is why I mentioned it.
