Okay, just wanted to be perfectly clear on this point... /static/ software builds don't link to /any/ shared libs, right? I.e., can a static-built C program run on a system without a libc installed?
View 1 RepliesI couldn't find any package containing a static version of the C library for 32-bit. Did I miss something or is it really not available, and if so is there a reason why?

I've configured/make/make installed fftw and its doing just fine in the usr/lib folder, so I'm at a loss at how to fix this. Do I need to build fftw again using some kind of shared make switch? I couldn't find any referance about that.
WindowsDude is back on the dark side of the web, the linux world, and he has encountered yet another impassable problem !There's a compiler mpicc, probably installed on the network at some location let's say /network/bin So when I write mpicc main.c I get the "can't find command" (or similar) error. Somehow it's supposed to work anyway. I think I need one of those magic commands to make it work. But the question is; which word will make it all happen? (I thought the DOS days were over!) I guess I could use the full path (provided that that binary really is in that folder), I want to bind that executable at that location to the much shorter mpicc.

What is the purpose of libc in an operating system?
Is the libc is common for all OS or it is different for different OS!?
I mean source of libc build for RH is same for Ubuntu !?
1. I need to use clock_gettime(), in <time.h> it is: extern int clock_gettime (clockid_t __clock_id, struct timespec *__tp) __THROW; and in a successful build .so it is unsolved. In final app to lonk to this .so it is also unsolved. which lib missed in .so or app build?
2. libc include several libs, which are liked by default? say stdc++, rt? rt1/rt2 what does they do?
3. How to find which libc is used or linked?

I want to add my C program's path to the environment variable PATH. My C program called "md5". So that I can execute it from anywhere (i.e any directory). My md5 program is located at "/home/ahuq/MappingServer/md5_program". So what I did was to put: "export PATH=$PATH:/home/ahuq/MappingServer/md5_program" in the running SHELL. This only makes temporary changes and lets me run the "md5" program from anywhere temporarily.
root@ahuq-kitchen:/home/ahuq# md5 -sanis MD5 ("anis") = 38a1ffb5ccad9612d3d28d99488ca94b But I want to make this change permanent. I tried to put the line "PATH=$PATH:/home/ahuq/MappingServer/md5_program" at the end of "/home/ahuq/.bashrc" and "/home/ahuq/.profile" files. I logged out of the SHELL and
went in again. But it didn't work:
root@ahuq-kitchen:/home/ahuq# md5 -sanis
No command 'md5' found, did you mean:
Command 'cd5' from package 'cd5' (universe)
Command 'mdu' from package 'mtools' (main)
Command 'mdb' from package 'mono-debugger' (universe)
md5: command not found
Maybe I am putting the PATH statement in the wrong place of the above mentioned files. There are a lot if-else-fi structures inside those two files. Do I need to put the PATH statement inside any of those structures? Do I just logout or do I have to restart the system to make the changes active?
I wanted to develop using some of the bleeding edge features of the new Qt framework, but there is no easy way to get 4.7.0 installed on lucid. The build is relatively easy with a few minor annoyances.
Code:
# first grab some general require packages
sudo apt-get install build-essential
# now grab the build deps for the current qt (mostly the same as for 4.7.0)
sudo apt-get build-dep qt4-x11
# need to grab some extra libs that are not build deps
sudo apt-get install libphonon-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
# grab the source package from [URL]
wget [URL]
# now configure qt 4.7.0 with declarative support
# the annoyances here are all the extra includes that are required
# i am installing to $HOME/qt/qt-4.7.0 but feel free to change that
./configure -prefix $HOME/qt/qt-4.7.0 -I/usr/include/gstreamer-0.10 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2 -opensource -declarative -confirm-license -v 2>&1 | tee config.log
# build (takes a while)
make
# install
make install
If anyone out there knows of a PPA that is building Qt 4.7.0, please let me know. I would be interested to abandon building it manually.
Any relatively easy user guide for the built in command line ftp program?

I need to monitor the amount of free physical memory on Linux from within a large C program. The sampling will occur very frequently, so the measurement cannot be performance intensive. The fact that Linux uses much of the theoretically free memory for cache and buffers means that just measuring the free pages is not sufficient. Using free + cache + buffers gives an overestimate as not all cache/buffers can be freed, but I could get a rough idea of how much generally can't and subtract that from the answer.
Possible options that I've come across so far are: Parsing /proc/meminfo - but that involves reading from file which is slow. Extracting the free, cache and buffers values from the output of the Free command - but is there a quick way to do this? Parsing the /proc/freemem file produced by the API here - but this is again reading from file. Is there a way to get that output directly? Speed is an extremely high priority, and the answer it must accurately represent the amount of memory that my program could expand into (to within a few Mb).
I'm trying to write a bash script program in the Linux command terminal that will write to a fellow user and then continue reading down the program. this is what i have (kind of explains the idea too):
#!/bin/sh

echo "this is before the write command"
write jcummins
this message should go to jerry
echo "the message didn't send and this string will not appear"
echo "it appears it has stopped at the write command"

View 9 Replies View RelatedI have a third party static library (libSTATIC.a) that I cannot recompile into a shared library. I want to create a shared library (libSHARED.so) that uses the C functions in the static library. Is it possible to do this? In other words, when linking a C program with gcc by using the -shared flag, is it necessary that all all libraries invoked in the program (even low level libraries such as libc for example) be available as shared libraries as well?

View 1 Replies View RelatedI'm building an RPM that requires adding a cron job into a user's(service account) crontab...from what I see in the manpages, this isn't possible, as the only viable option is to replace the crontab entries already there for previous scripts being run.

Code:
echo "* * * * * /bin/ls -la ~/ >> ~/ls.log" >> /var/spool/cron/userName

View 4 Replies View RelatedI built my slackware system from source code. Bootstrapped, toolchained etc.. The only thing I didn't change was the chost thinking that life would be easier if left alone @ i486. Would I have gained anything if I had used i786 or even pentium4 (pentium4-slackware-linux-gnu)?
I already got all the benefits of optimization when I used (still using) my own CFLAGS CXXFLAGS right? So changing the chost won't do anything speed wise will it? If I used march=prescott when compiling everything am I ok to just forget about the chost value? It's not gonna change anything will it?
