Error while installing libgraph-1.0.2

[Rahul04789]

Hi friends,

I am trying to install libgraph-1.0.2
After running ./configure command and then running make command, I got following error:

Makefile:934: warning: overriding commands for target `libgraph.pc'
Makefile:409: warning: ignoring old commands for target `libgraph.pc'

Thereafter , I installed guile from Synaptic Package Manager, but still the same error is shown.
What should I do???

You need to install guile-dev. (In general, header files (.h) are provided by -dev packages.)

@Bachstelze:

I have already installed guile-2.0-dev
Now, tell me what should I do....

[Rahul04789]

Hi Bachstelze,

I did the same but no effect took place.
So what should I do?

Which version of Ubuntu are you running?

[spjackson]

After installing guile-dev, did you rerun configure?

[Rahul04789]

Hi,
I am using ubuntu 12.04 LTE

[Rahul04789]

@spjackson:

Yes I reran the configure

[spjackson]

If you have installed the prerequisites properly, I am afraid I've no idea what your problem is.

I did a fresh install of 12.04


$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04 LTS
Release: 12.04
Codename: precise


Installed the prerequisites thus


$ sudo apt-get install build-essential
$ sudo apt-get install guile-1.8-dev
$ sudo apt-get install libsdl1.2-dev
$ sudo apt-get install libsdl-image1.2-dev


Checked I'd got libguile.h


$ find /usr/include -name "*guile*"
/usr/include/libguile.h
/usr/include/libguile
/usr/include/guile

Yes, I have, so get the source and build it...


$ wget http://download.savannah.gnu.org/releases/libgraph/libgraph-1.0.2.tar.gz
$ tar xf libgraph-1.0.2.tar.gz
$ cd libgraph-1.0.2/
$ ./configure
$ make

and it builds without error. What are you doing differently?

[Rahul04789]

@spjackson:

Thanks for the help. Now it has been installed
Actually I had installed guile-2.0.
So, I followed your steps again, and now it's done.
Thank you.

But, now while compiling a .cpp file for graphics I encountered the following error:

rahul@rahul-VPCEG28FN:~/CProgram/Graphics$ g++ aa.cpp -lgraph

/usr/bin/ld: error: cannot find -lgraph
/tmp/ccntOaHb.o:aa.cpp:function main: error: undefined reference to 'initgraph'
/tmp/ccntOaHb.o:aa.cpp:function main: error: undefined reference to 'line'
/tmp/ccntOaHb.o:aa.cpp:function main: error: undefined reference to 'closegraph'
collect2: ld returned 1 exit status


Please tell me where doing wrong.....
Thanks

If your library is not in one of the default places searched by the g++ link command, then you need to tell it where it is.

./configure by default normally results in "make install" putting libraries in /usr/local/lib. I haven't checked whether this is the case here, but assuming that it is, then you need


$ g++ aa.cpp -lgraph -L/usr/local/lib

Then when you come to run your executable, you will need to set LD_LIBRARY_PATH (see "man ld.so") or add you library via ldconfig (see "man ldconfig").
