A problem during PGPLOT installation
 

Hi,

I am trying to install PGPLOT on my Ubuntu Linux and I have installed
all required libraries and packages. But when I type "make", after running
about a dozen of lines it stops with this error:

***********************************
/usr/bin/ld: cannot find -lX11
collect2: ld returned 1 exit status
make: *** [pgdemo1] Error 1
***********************************

Since I have installed all the required libraries and also modified the
"makefile" according to the instruction, I do not know what is this error
for.

Would it be possible for you to help me in this problem?

With best regards,
Hassan

Are you sure you have X11 installed?

David1357,

I do not know how to thank you for your
GREAT HELP.
You were right, I had not installed all
libX11 libraries when I checked and
compared with your list.
This problem took one month of my time
and you solved it in an instant.

Thanks Again.

Why build 'pgplot' when it is available as a package ? ?

sudo apt-get install pgplot5
.....
.....

If you want to build it anyway ...
The "Ubuntu" source is code here
http://packages.ubuntu.com/karmic/math/pgplot5
> Links for pgplot5 > >
[pgplot5_5.2.2.orig.tar.gz], [pgplot5_5.2.2-15.diff.gz]


The 'build-depends' list :
http://packages.ubuntu.com/source/karmic/pgplot5

libx11-dev libxaw7-dev libxt-dev x11proto-core-dev

gfortran libpng12-dev zlib1g-dev libgif-dev perl
.....

You are very welcome. However, next time, don't wait a month before asking for help. The people in this forum are climbing over each other to try and answer questions like this... ;)

I have this same problem, but I *DO* have libX11 installed:

g77 -fno-backslash -o pgdemo1 /usr/local/src/pgplot/examples/pgdemo1.f -L`pwd` -lpgplot -L/usr/X11R6/lib -lX11
/usr/bin/ld: cannot find -lX11
collect2: ld returned 1 exit status
make: *** [pgdemo1] Error 1


[root@here pgplot]# locate libX11
/usr/lib/libX11.so.6
/usr/lib/libX11.so.6.2.0

Running Centos 5.4

Hi,

This thread is mine and I know exactly what is your problem!!

You must install libxext-dev too.

Then type "updatedb" in your terminal.
And your problem will be solved.

Best,
Hassan

That did it! Thanks!
