correct path in gphoto2

[doggiebone]

Hi guys

finally done it got me self the digi kamera ;D.


Ok I installed libgphoto2-2.1.1 when I go to install gphoto2-2.1.1 after running the ./configure comand half way down I get this error.

--------------------

checking for pkg-config... /usr/bin/pkg-config
checking for libgphoto2 >= 2.1.1... Package libgphoto2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgphoto2.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgphoto2' found

configure: error: Library requirements (libgphoto2 >= 2.1.1) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
-------------------------

There is no pkgconfing in /usr/bin cos I've checked. I tried copying the pkgconfig but that did not work.

Secondly what should be path be when I edit the pkgconfig/libphoto2.pc file. At this point I'm alittle stuck

Any help appreciated

maybe if you run /sbin/ldconfig before you try and compile gphoto
what distro are you in, anyway?

hi alastair

There's documentation saying that you need to run sbin/idconfig. Was going use a storage medium only to find I ordered the wrong one so while I'm waiting thought I get gphoto2/gtkam to install.

I'm using RH8.0 2.4.18 18.8.0 256mb , 20gbhdd

redhat....
use the rpms
they will be _far_ easier to install

Hi M8

I have to use source cos the current rpm dont support my kodak dx430, if there was rpm I would use it. All I wanting to know is what should go in pkgcofig path. So I can continue compiling gphoto2/gtkam >

i believe what it is asking is for you to link libgphoto2.pc to the directory of pkg-config. So find libgphoto2.pc and use the 'ln' command to link it to pkg-config's dir

[doggiebone]

I'm not sure how to link it cos I dont know the command ;D in the /usrbin/pkgconfig/libgphoto2.pc resides. but the libgphoto2-2.1.1 resides in /usr/local/share/libgphoto2/2.1.1 Where does the link want to go? This has been bugging me for days. Babbings is there a site with commands that I could aqainte myself with?

sorry all you have to do is add the dir of libgphoto2 to the PKG_CONFIG_PATH, no biggie, and i found a cool little thing to help you on your way. Have Fun!

$./configure
/* I received the error message above*/

To fix this you need to setup an environment variable for PKG_CONFIG_PATH so that it is set to the directory where the file libgphoto2.pc is located. There may be multiple ways to do this with all the different distro's out there, some of which were setting environment variables in ~./bashrc or bash_conf. So here is what I did in bash with Slackware 9.0.0-beta on an A7A266/1.4ghz system.

$echo $PKG_CONFIG_PATH

/* if you had an error this will most likely output a blank line, or possibly something that you recently set it to */

$cd /

$find -R | grep libgphoto2.pc
/* this outputs to your screen the directory info of all the libgphoto2.pc files in all subdirectories from / The directory you come up with may be different than what I came up with as shown below */

$export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
/* this sets the environment variable for PKG_CONFIG_PATH */

$echo $PKG_CONFIG_PATH
/* the screen output of this should be what is after the = in the export command above, and now that you have the environment varialbe set you should be able to successfully install gphoto2-2.1.1.tar.gz and gtkam-0.1.10.tar.gz*/

$cd gphoto2-2.1.1
$./configure
/* this should now configure without the error message */


Goodluck,

in my /user/bin/pkgconfig

prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ <--- I had to add this it wans't there

at this point I'm banging my head alitlle thanks for your help. I gonna go for a drive and come back to it. later >

n my /user/bin/pkgconfig

prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/

earlier you told us that libgphoto2 was at /usr/local/share/libgphoto2/2.1.1

extract your head from monitor, apply ice, and reconfigure ;D ;D ;D ;D ;D
