Ubuntu :: Compiling Libs Under A Different Directory
Feb 21, 2010
I am fairly new to ubuntu. I have to compile some libraries under ubuntu in a directory other than the default directory and then get the shared object libs (.so) libs for building some custome kernels. I created a directory structure as follows:
/home/username/build-target
/home/username/src-<libname> =>here are the source files for the lib. I need to compile
Now I create a directory /home/username/src-openssl and download the source code and untar it under this directory and issue ./configure --prefix=/home/username/build-target --exec-prefix=/home/username/build-target and then make and make install. I was expecting that the shared object libraries created (.so) files should have gone under /home/username/build-target/libs, however I just see only libssl.a and libcrypto.a and not .so files under the build-target/lib directory. For grep also I did the same thing as above however I don't see any lib directory created under build-target directory as I was expecting.

I am trying to write modular program but when I try to compile I come to know I don't have any files in /usr/src/linux. I have installed fedora 12 which has 2.6.31.5-127.fc12.i686.PAE. I am including in my code:
linux/kernel.h
linux/module.h
Those are not present directory in /usr/src/linux is not present. My goal is to compile modular programs.

I'm having problems with compiling recursive Makefiles in my directory structure:
My folder layout is:
top/|- one/|- one.c (With main function)|- zero.c|- two/|- two.cin my top folder the make file looks like:
Code:
MAKE_DIRECTORIES = one two
.PHONY: all
all: $(MAKE_DIRECTORIES)
.PHONY: $(MAKE_DIRECTORIES)
$(MAKE_DIRECTORIES):
@echo $@
$(MAKE) --directory=$@
in my one and two folder I have the following Makefile:
Code:
.PHONE: all
all:
@echo $@
$(CC) $(CFLAGS) *.c
But when I compile it from top folder: make
I get following output:
Code:
one
two
Which states that directory statement by echo in main Makefile is ok but the files are not compiled in one and two.

I am building a BLFS (Beyond Linux from Scratch) system. I am using a Slackware style package management system. Currently I am trying to build xorg-server-1.1.1 but whn it come to finding libfreetype.so its looking in my build directory (/tmp/mybuild/pachage-freetype/usr/lib/) and not /usr/lib/. I checked /usu/lib/pkgconfig and found that my freetype2.pc (amongst others) file was pointing to my build dir so I fixed it (along with all the others). but when I try building again I gat the same error. I checked my $PATH and my $PKG_CONFIG_PATH and both are correct.
this is a snip of my terminal output
Code:
(cd .libs && rm -f libosandcommon.la && ln -s ../libosandcommon.la libosandcommon.la)
if gcc -DHAVE_CONFIG_H -I. -I. -I../../include -I../../include -I../../include -I../../include -I../../include -I../../include -I../../include -I../../include -

I need some PHP libs that don't come with the standard install - I assume that means I'll have to build PHP from source. Can I use a package manager to download the source? How? If I do, will it have the code for all the libraries? Are there specific instructions for building and installing on ubuntu?

i was trying to remove the flash plugin 32bit wrapper (don't remember the exact name of the package),using the command apt-get -y remove --purge and i saw somehow uninstalled a bunch of other programs like the gnome-network manager,emphaty...Now i rebooted and can't log on anymore .Is there a way to repair this,like running an upgrade from the livecd to restore the missing parts without wiping out my conf & other programs ? I've tried this that i found some other forum ,but i didn't work
Code:
sudo mkdir /mnt/repair
sudo mount /dev/sda3 /mnt/repair

I wanted to install an rpm package on two suse 10 systems. It installed successfully on one system but on the other it throws an error like
Code: error: Failed dependencies: rpmlib(PayloadIsLzma) <= 4.4.2-1 is needed by linuxProj-1-1.noarch
Now this means that rpnm package has no error but the rpm in itself is lacking some libs. So can anyone tell me that how can I download and add these libs to the already installed rpm. Note the difference between rpm and rpm package.

My friend just installed Ubuntu from cd on a computer without Internet connection. She hoped to be able to open some video and music files there, but it turns out there were no proprietary libs in the installer. And since the majority of the files were avi, mp3 and mp4, they couldn't be read.I am an experienced Linux user, but I have mainly dealt with Gentoo, plus I'm used to be able to download and install programs directly through a package manager. However since my friend's computer isn't connected we don't have that possibility.
how can I install proprietary libs (like for the formats mentioned) to this computer? Could they be available from the installation disc, and if so how do I get them? Can I transfer packages with a memory stick? (And is there some easy way to find all dependencies?) Or any other solution?I do have a 3G mobile modem dongle which perhaps we could use. However I have bad impressions of those and Linux. Will it work without a great deal of configuring (or extra software)? Otherwise, this method would mean an extra step.

Im trying to build ffmepg with shared lib under ubuntu 8.04 hardy. Im was following these instructions :
>> Install FFmpeg and x264 on Ubuntu Hardy Heron 8.04 LTS <<
But it was not for shared library. So in the part 7. I added "--enable-shared" to the "configure" command but when I compile ("make") I ve got an error:
"
/usr/bin/ld: /usr/local/lib/libopencore-amrnb.a(wrapper.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libopencore-amrnb.a: could not read symbols: Bad value
[code]...
I read another thread saying how to resolve this error :
>> trouble with ffmpeg and shared libs <<
but its still make the error when i follow these instructions...
I decided to add "--enable-pic" flag to "configure" but the error still happen.

I'm trying to install OpenDX(dx)-4.2.0, a scientific graphics visualization tool on Suse Linux 10.1 . But its giving following error:
icc -DHAVE_CONFIG_H -I. -I. -I../../../include -I../../../include -Dlinux -I/opt/intel/MESA/7.5.2/DRI2PROTO/include/X11/extensions -I/usr/X11R6/include -g -O2 -I/usr/X11R6/include -D_GNU_SOURCE -c callm_xinit.c
callm_xinit.c catastrophic error: could not open source file "Xm/Xm.h"
[Code]....
To resolve this error, I tried to install Mesa OpenGL libraries (mesa-7.5.2). But its not getting installed even after resolving dependencies such as libdrm, dri2proto, libpthread-stubs.
Are there any rpm distributions available for mesa libraries on Suse?

I recently upgraded my RHEL system from 5.5 to 6.0. When I went to install a 32-bit application I got the normal failure for missing 32-bit libs (/lib/ld-linux.so.2: bad ELF interpreter: No such file or directory). With RHEL5, simply installing ia32-libs takes care of this problem.
In this case, a "yum search ia32-libs" shows no such package exits. So either it doesn't exist or I've got a yum config problem (although I can pull x86_64 packages just fine). If it doesn't exist, is there an equivalent package?

I am trying to locate the ia32-libs package, no luck. This is for squeeze. Is there a source (for inclusion in sources.list) that serves this package?

I assumed this had to be a FAQ, but after hours of searching, how to do this on FC11, but that didn't work with the yum on FC10. I don't need a huge list, but at least the basics (ld-linux.so, and I imagine the C++ compatibility libs).

After upgrading KDE from 4.6.0 to 4.6.3 SpiderOak will fail to run with message. Cannot mix incompatible Qt library (version 0x40703) with this library (version 0x40701). There's no more SO package in Non-OSS, apparently due to some support issues. That's a pity, since Dropbox had conceded access to US agencies, IMO SpiderOak is a really good option, and has been working very nicely until now. Anyway, Yast tells me that KDE 4.6.0 uses Qt 4.7.1, while 4.6.3 brings in Qt 4.7.3. A possible solution may be found here, originally for Qt 4.7.2. I'll try it and report.

There are three new "k1DZ 1n the Block" for CAD users in Linux :
Bricscad
Ares Commander Edition
Draftsight
there used to be Varicad, which also runs in 64 bits natively, as well as QCad ( 2D only ) and BRLCAD ( more of a solid modeler than a Drafting program ), both built from source. Those new K1dZ out there are awesome, but they only run in 32 bits. My system is Squeeze 64 Bits and has multilib enabled... i can install the *deb, and it complains about architecture, so i use --force.. default install is in /opt... still this asks for some libraruies which i do have for 64bits, but do not exist for 32...
So my questions are :
Should I install these 32 bits libraries to run the application ( mostly issues related to rendering ) they would land in /usr/lib32/...
But naming convention in apt or synaptic would still refer them by the same name as their 64 bits counterparts. How does apt (synaptic ) deals with this?
I find all this to much of an unnatural thing to do to my Squeeze install just to make an app fit and run. So far I can remove the app using synaptic but I am very reticent about installing those 32 bits specific libs required by the app. I already have the ia32-libs metapackage installed.

Trying to build the required libs for synCE, www.synce.org, as listed in their web site under building from sources. Came upon a snag, on building the odccm library which needs gnet-2. I loaded gnet-2 from my distribution DVD, and then did an #ldconfig afterwards, but it still says that it needs gnet-2. Not sure why it can't see it. I tried to build gnet-2 from source, but had a difficult time finding it as it is deprecated and Gnome only had the latest build which did not build (errors).
From configure script for odccm-0.11: no package 'gnet-2.0' found. Part of configure script is below.
Code:
if test -n "$PKG_CONFIG"; then
if test -n "$GNET_CFLAGS"; then
pkg_cv_GNET_CFLAGS="$GNET_CFLAGS"
else
if test -n "$PKG_CONFIG" &&

I'm trying to change a group of cpp files to one shared lib. I have created a shared lib with a single file. I then did this with a group of files. The difference in what I'm doing is that before with the single file, .a, was added into a single .o file. Now I'm trying to add it to my main.cpp file which is NOT a .o file. I'm now getting these compiler errors from the main.cpp where is doesn't seem to recognize the semaphores.Example Error: undefined reference to `sem_wait'If I were not to use the share libs this compiles and runs as I expected it to.Something tells me this is a compiler flag issue, at least I hope it is

Are there some effective tools to purge the system of unused libs/pkg and other files?Till now I found localepurge (i do not remember where i found it) which does some trick, but I am sure there is a lot of other things laying around in Slack with no real reason to be there in some minimal installation.I found also unsuedpkg in google.code, but it does nothing on a fresh system.Such question won't rise if Slack team wouldn't be forgetting about Slack's significance in server segment and putting big efforts in "deskopisation" of it. I'd be happy seeing directories like xlibs/ and mm_stuff/ where all x related libs and multimedia related ehhh... files could go (I hope developers will see this message).

I've been having problems with Dolphin hanging on me and I found out that the problem is due to something with dbus 1.2x. So I downloaded the source for dbus 1.3.1 and proceeded to update dbus by incrementally uninstalling and installing all of the packages it requires. Today I noticed that both dbus-libs 1.24 and dbus-libs 1.3.1 were installed, so I went to get rid of the 1.2 version so that yum would stop telling me there was a conflict.
This is what I did:
Code:
su
rpm -e --nodeps dbus-libs
rpm -Uvh file:///root/rpmbuild/RPMS/X86_64/dbus-libs(versionNum).rpm
I ran that once and restarted, but I think that something happened the first time because rather than it replacing the 1.2x version with 1.3.1 all that was left was 1.2x. So I did the same process as the last time, but after removing dbus-libs I forgot the path to the RPMbuild so I closed konsole and tried to open Dolphin. Well, obviously that's not going to work. So then I, even more stupidly, restarted... And now Fedora won't boot up. How do I reinstall dbus-libs without a bootable Fedora?

I need to cross-compile some libs for using in a ARM11 board running Linux (at this time, 2.6.28, but I'll try update it... and for costs reason, maybe it turns on a ARM9 board). The libs are libfprint, libusb-1.0 (that is a requirement of libfprint), libSDL (and some of its extensions) and maybe libsqlite3. How I can make this, with the development files in the host machine (an Ubuntu 10.04 32bits machine) and the runtime files at the host ARM11 Board.

I untared a few libs on the wrong server (that's the when you're supposed to start laughing!) and I corrupted my server. Everytime it boots up, I get the following error:
/sbin/init: relocation error: /lib/tls/libc.so.6: symbol _dl_out_of_memory, version GLIBC_PRIVATE not defined in file ld-linux.so.2 with link time reference. Kernel panic - not syncing. Attempted to kill init!
I can I restore the original libs? I'm running RHEL 2.6.9-42 on a Proliant DL585.
