System - KDE 4.5.1 on Kubuntu 10.10 beta (updated till date).

When trying to compile I am getting the following error :

"ERROR: Could not find libproc devel package
(proc/readproc.h;proc/sysinfo.h).

In ubuntu: sudo apt-get install libproc-dev

-- Configuring incomplete, errors occurred!"

Trying to install the above package is giving error as "E: Unable to locate package lilbproc-dev"

Please help so that I can install this plasmoid.

Contact kubuntu developers about libproc package. In archlinux it is packaged as procps.
# pacman -Q -o /usr/include/proc/readproc.h
/usr/include/proc/readproc.h is owned by procps 3.2.8-1

Thank you very much!
I was looking for something like that for a long time.
I had to modify it a bit, so it fitted into my sidebar.

After I installed the right devel-libs, it compiled without errors on debian.

I've a random crash (~once a week, PC is always on) of kdeinit4 on ubuntu karmic.
I've send report to bugs.kde.org, and they've told me that it's a bug of toplike widget (line #7 in stack trace).

There is a link to my bug report:
https://bugs.kde.org/show_bug.cgi?id=215034

And today I've another crash with very similar stack trace:

Actually, it looks like ubuntu has a patch for libproc that makes freeproc and read_cmdline functions public. So it doesn't look like this plasmoid is compilable on anything else than ubuntu.

solanum

Agreed. libproc is provided by procps on Mandriva and the compile fails with the same error when I try.

I knew the rise of Ubuntu was going to be a problem for the rest of us!!

AlexeyTyapkin

May be, I've compiled it on kubuntu.

Are you using x86_64 bit linux?

Try to add following CMakeLists.txt:
IF("${CMAKE_SYSTEM_PROCESSOR}" STREQUAL "x86_64")
SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -fPIC" )
SET(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_DEBUG} -fPIC" )
ENDIF("${CMAKE_SYSTEM_PROCESSOR}" STREQUAL "x86_64")

If it will helps let me know. I'll add it to next version

libproc development lib
e.g.:
/usr/lib/libproc.a

TheRob
11 years ago

hmmm, I have:
/lib/libproc-3.2.8.so
/lib/libproc.so

but no .a file...
gonna try and create a symlink...

thx

AlexeyTyapkin
11 years ago

I think this doesn't help. Because *.a it is static library archive.

Tell me what linux distro do you use. I'll try to find out where is the issue. Or may be your distrib has something like libproc-static-devel.

TheRob
11 years ago

Thx for helping.

distro is gentoo...
...package in gentoo that has libproc
file is called procps.

I can't find any packages that could have
the libproc.a file... ..or at least any kinda
devel package as gentoo is a source
based distro it should be able to compile
most the programs.

did a quick google about the libproc.a
file and came up empty.

I haven't installed any plasmoids in a while
but all your 3 seems to be top notch,
been wondering when we'll see some
desent cpu/mem plasmoids :)

AlexeyTyapkin
11 years ago

Try to compile static procps devel package. I'll investigate why it doesn't want to compile with dynamic lib.

TheRob
11 years ago

I rather not do that....

I guess I can live without this, it would
be nice tho... if you find out a way to compile
this with dynamic proc lib update it or
let me know :)

Thx for the help.
