Instead of cluttering your PATH with every bit of software you want to run (as you would in Windows), the preferred way is to create a link in one of the standard bin directories, e.g.:

Code:

ln -s /usr/lib/mozilla-1.7.13/mozilla /usr/bin/mozilla

(or whatever the mozilla binary is called...)

no am giving the total output in make file library path..
it will dynamically check the mozilla version and get the perticular ".so" file..

i tried this in make file of the source code

Code:

k=" "
k=`rpm -ql mozilla | grep /usr/lib/mozilla- | tail -1 | cut -d/ -f4`
path=`whereis $k |cut -d" " -f2`
full_path="$path/$i"

i suceeded to get the path but have to implement in make file.help me.

If you know enough of the library name you need, couldn't you use locate instead.

I don't have the mozilla browser installed. So I'll use another example:
mozlib=$(dirname $(locate libxaa.so))

Then you could use this:

Code:

gcc -g -O2 -o phone main.o support.o interface.o callbacks.o -L/root/.fedora -L${mozlib} ...

If you are writing a makefile, You could try using something like:
mozlib := $(shell $(dirname $(locate libxaa.so)))

great work..
mozlib := $(shell $(dirname $(locate libxaa.so)))
the above line will help me more top write in make file am very near to get the solution for it.....

but in some machine mozilla path will bw varied..
ex: in fedora it is /usr/lib/
in suse /opt/
....like that..

so that i tried this in make file...

Code:

k=" "
#k=`rpm -ql mozilla | grep /usr/lib/mozilla- | tail -1 | cut -d/ -f4`
k=`mozilla -V | sed -e 's/\([^,]*\),.*/\L\1/' -e 's/ /-/'`
path=`whereis $k |cut -d" " -f2`
#full_path="$path/$i"
full_path="$path"
#mozlib := $(shell $(dirname $(locate libxaa.so)))
mozlib := $(shell $(path))

and at the library

Code:

gcc -g -O2 -o phone main.o support.o interface.o callbacks.o -L/root/.fedora -L${mozlib} ...

now the output at the terminal is

Code:

gcc -g -O2 -o phone main.o support.o interface.o callbacks.o -L/root/.fedora -Lmozilla-1.7.13 ......

i wud like to insert all the path(not manually becouse let us say i dont know where the mozilla-1.7.13 is) in this "mozlib := $(shell $(path))"

do you know..full_path contains solution but it did not working...
what i have to do....

please help me .. it is near to get solution

thank you in advance

I'm not certain I get what your question is. Maybe you want to get the directory name from the full pathname. You can use the "dirname" command.

example:

Code:

mozdir=$(dirname $(locate -r '/usr/lib.*libplain\.so\.' | head -n 1))

Notice that you can embed one $( .. ) inside another. That is one reason the using $() is better than using backticks.

Again, I tested this on a non-mozilla library file because I don't have it installed myself.

no..no. not this..
i tried this

Code:

k=" "
k=`mozilla -V | sed -e 's/\([^,]*\),.*/\L\1/' -e 's/ /-/'`
path=`whereis $k |cut -d" " -f2`
mozlib := $(shell $(path))

here "path" contains the total path of the LIBdirectory...i.e
/usr/lib/mozilla-1.7.12
but am getting only
mozilla-1.7.12 in the make file

what i have to do to get /usr/lib/mozilla-1.7.12

thank you in advance

The previous suggestion I made: mozlib := $(shell $(dirname $(locate libxaa.so)))
doesn't work as I thought it would.

You could export the mozlib variable and then run make. Here is an example:

Code:

> unset mozlib
> export mozlib=$(dirname $(locate libxaa.so))
> make
echo mozlib: /usr/lib64/xorg/modules
mozlib: /usr/lib64/xorg/modules
> cat Makefile
all:
        echo mozlib: $(mozlib)

Your makefile could add your variable to what you already have defined in the makefile with a command like:
LIB += $(mozlib)

Code:

cat Makefile

LIB = /usr/local/lib
LIB += $(mozlib)
all:
        echo mozlib: $(mozlib)
        echo LIB:    $(LIB)

> make
echo mozlib: /usr/lib64/xorg/modules
mozlib: /usr/lib64/xorg/modules
echo LIB:    /usr/local/lib /usr/lib64/xorg/modules
LIB: /usr/local/lib /usr/lib64/xorg/modules

munna_dude · 07-28-2007, 06:56 AM

sorry it is not working...
mozlib := $(shell $(path))
here you used the word shell,
what is the shell here.
can you please explain about it..
is there any command like shell(in linux script for make file)..

thank you in advance

jschiwal · 07-28-2007, 07:59 AM

Reread my last post. I said it didn't work for me either. Then I suggested evaluating the variable outside the Makefile, exporting the variable, and then using the variable in the Makefile.

You might want to read 8.11 in the make info manual for $(shell ..) examples.
