I've been trying for days now to build my first FastCGI application using gcc.
This is the output:
I believe I wouldn't have to refer to the lib path, but I added the -L flag to be sure.
The directory /usr/lib includes (among others) these files:
I have tried to follow these instructions. The files in the tar.gz archive provided by FastCGI.com no longer corresponds to the instructions there, but I was still able to run the ./configure and make commands so I believe FastCGI is installed.
But why can not the library be properly linked to? Really hope you can help me out on this one!
I accidentally deleted one of the libraries in /lib or /usr/lib and now when I boot into Debian, it won't load the GUI. I get an error message saying that something failed because the library needed did not exist (I couldn't read it because the text was scrolling by so fast, so I don't know exactly what it said). I need to find an archive or something of all the system libraries for Lenny so I can reinstall them. Is there a place online where I can download them?
As title says, running unetbootin throws this error [URL]...... I can easily find the files myself (go to synaptic > look at installed files > scroll down) and I can't remove/purge because they would require me to remove some important software (XFCE).
where can i find the qt libraries..?? building an rpm failed.
Code: checking for Qt libraries... no :-( configure: error:
I can't find the Qt libraries. It is recommended to set the QTDIR environment variable. Install the Qt libraries, or if you have them installed, override this check with the --with-qt-libraries argument, and I'll take your word for it. i got qt and qt-devel
I have just downloaded, configure'd, make'd and make install'ed the Google Log Library to my computer. It built all required files (as far as I can see) and copied the .so file (libglog.so.0.0.0) to /usr/local/lib. Then it created two symbolic links called "libglog.so.0" and "libglog.so" that point to that shared object file:
I am trying to set up my Apache server with FastCGI as the CGI engine. It will be mostly running PHP, but I may add Perl or something else later. I started from a completely fresh install of Ubuntu 11.04 with every update available. I used the install CD to install a LAMP server as part of the system install.I am using the tutorial at URL...to add the FastCGI functionality. I am having some problems with getting everything to work.The first problem was that apache2-suexec-custom wouldn't accept a different document root. I fixed that by compiling apache2-suexec from source with the document root changed to the correct path.
The next problem is that every php page I load throws a 500 error. Apache's error logs show that FastCGI isn't returning the page data correctly to Apache.
I ran 'sudo apt-get install python', which completed successfully. According to [URL] this should have created the directory /usr/lib/python2.6, but I do not see any such directory.This is causing problems:
$ python Could not find platform independent libraries <prefix> Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
I've tried 'apt-get purge python' and then reinstalling but this has not resolved the issue.
I tried to build firefox with PGO using Intel C Compiler (icc), but, configure gave this error message.
Code: configure: error: Could not find the following X libraries: -lX11 -lXext -lXt *** Fix above errors and then restart with "make -f client.mk build" When I tried it using gcc, there's no error msg. What can I do? My .mozconfig file is... Code: export CC=icc
Im doing a project,in which i have to add a script in c++ inorder to merge two or pdf files page by page or based on some headindgs.SO anyone can please suggest me any open source pdf libraries in c++ which provide functions for merging and splitting.
I am trying to install some NVIDIA drivers on my machine. I went through the process and got this message:
Code: Select allWARNING: Unable to find a suitable destination to install 32-bit compatibility libraries. Your system may not be set up for 32-bit compatibility. 32-bit compatibility files will not be installed; if you wish to install them, re-run the installation and set a valid directory with the --compat32-libdir option. URL...Where in I ran this in the terminal to create the 32-bit document tree.
Code: Select allsudo apt-get install ia32-libs
E: Package 'ia32-libs' has no installation candidate.
I really just want to get these NVIDIA drivers up and running. I already installed and updated the headers to just be able to half-way install the drivers (the second monitor works now).
I am learning C++ and wish to include some Boost functions in my code. My machine is running Debian Linux with the pre-installed boost binarys.I have a couple of questions:How do I include the library in my C++ code as there are no cpp or h files only binary files (eg /usr/lib/libboost_regex-d.so and /usr/lib/libboost_regex-d.a)How do I comile the code. I am using DialogBlocks for creating forms using wxwidgets. The editor also compiles the code using the gcc compiler. Do I have to give an instruction to the compiler saying which file is requried and where to find it? If so, any ideas how this is done?
I am stuck with a problem to link static libraries with gcc. There is no problem with source files since I am able to compile in a machine where the static library is installed. I am compiling with the following: Code: :~/Emotion/pjproject-1.0.3/third_party 157% gcc -Wall -I/portaudio/include -o rec patest_record.c -L./lib -lportaudio-x86_64-unknown-linux-gnu
So I decided to take my first steps into programming with C + gtk. So far I have doneI loaded eclipse and ensured I had the cdt package Created a new C/C++ project called "play" Added a new source file called "Playfullsrc.c" Added the following to paths and symbols (output of the command: pkg-config --cflags gtk+-2.0)
added "/usr/lib/libgtk-x11-2.0.so" to GCC C Linker Libaries (I have cheacked and this file exists) When I build the project I get the error message "cannot find -l/usr/lib/libgtk-x11-2.0.soplayline 0C/C++ Problem" I have been following this tutorial: [URL]
This post isn't really asking for a tutorial, but rather asking for some ideas. I've come up with a few ideas, but they seem cumbersome and unnecessary, so I was wondering if someone with more experience than me could out. Also, my explanations suck, but I'll try to do my best. So say I have an executable called X. At some point during its execution, X loads and uses (using dlopen and dlsym) a library called Y. In Y, there a bunch of functions that call the function called, for example, void *special_malloc (size_t). These functions come from another linked library (linked during compilation) called Z. Problem is, special_malloc contains some static variables within its scope, and when those variables are reset midway through a program, an invalid free occurs (special_malloc uses garbage collection). Now, what I want to happen is that whenever lib Z calls special_malloc, it instead calls the special_malloc defined in the executable X, so that these static variables are retained. Keep in mind that I have control of the Z library, meaning I can edit the source to fit my needs.
I'm using debian and, though i'm new to c++, i'm writing a program using it which needs some HTTPs functionalities . I found these libcurl libraries could help me but I haven been able to use them from my program. I installed them (power trio configure -make -make install ) but i guess i'm doing something wrong ... i feel like i should copy or link them somehow in my project (besides the include sentences in my code). I hope you could give me a hand with this im quite lost
I am using the API libpcap in order to filter the traffic of the port 53 from my PC ro other PCs, in other words the DNS traffic.I want to get more information about the DNS traffic that is being sent to the DNS server, in other words the queries. So far I have no idea how to read the information data or payload of the UDP package in order to read the content of the traffic for example if there is any PTR, A, MX, etc Resource Record.According to the RFC 1053 there is a header that is possible to use in order to easily get this info.
Any good tutorial on sharing dynamically allocated objects across shared libraries in the same process and between shared libaries and main(). In particular, I need to know what creation and destruction sequences are valid when libraries are being loaded and unloaded. For example, is it valid to allocate an object from inside a shared library procedure, and then delete that pointer from a different module, especially in the case where the allocating module has already been unloaded.
I imagine there might be all kinds of problems with this. Although my preliminary tests seem to work most of the time, I get crashes from time to time, but I'm not sure if they're caused by memory management or by threading issues. I've been restructuring my code to use a global context object to manage object creation and destruction from main(), but I'd like to find a clear exposition of the specific issues I'm dealing with before I go too much further.
I have been a predominant Windows user for a long time but shifted to Ubuntu recently. I was just trying out a few basic C functions when i realized that the "conio.h" header file isn't included in the libraries and therefore i was unable to use the "clrscr()" function.
I downloaded a tarball which contained the necessary library and header files including conio.h. Once extracted, i specified the location and included in the program as " #include "path to the header file" ".
I still didn't call the "clrscr()" function, and it compiled successfully. Next i edited the program to call that function and it gave the following error...
Since I read that executing a library could return its version number, I ran "/lib/libc.so.0" on uClinux, but it triggers an error.I'm told that random libraries are not directly executable. Does someone know what a random library is?PS: In case that matters, here's the short version of the error:
Code: Undefined instruction <5> - May be used to emulate instructions that are not defined for
Why many Linux distros are trying to use always the latest versions of the libraries and don't save the old libraries for compatibility? I mean, I can see libtiff for example, i can found a libtiff.so.5 on my /usr/lib, but doesn't store a libtiff.so.4 or 3 just for binary applications or games. For this example, I need libtiff.so.4 for uplink.
That should happen too on the old version of sims for linux, some ID games or others.What's wrong with storing old libraries? PD: Yay, my first post on 3 years!
I would like to ask you something about open-source and linux. Is it possible to make a commercial application for linux and sell it compiling it with linking to open-source libraries without altering them and consequently without allowing download of the source code and without making the application itself free?
I am trying to compile a C++ source file into a static library using make with root privileges (i.e., using "sudo"). However, I "sometimes" get the following compilation error:
Code: g++ -Wall -g -fPIC -W -c /home/project/ether/src/packet-ethernet.cc ar -cvq libether.a /home/project/ether/src/packet-ethernet.o ar: /home/project/ether/src/packet-ethernet.o: No such file or directory make: *** [libether.a] Error 1
I checked /home/project/ether/src folder to see if packet-ethernet.o in fact does not exist, and saw that it is actually located there, but its owner is "root", which is different from the current user. If I change the owner of packet_ethernet.o from root to the current user using "chown" command and execute make again with sudo, everything seems to be fine.
It may be a coincidence that I recently migrated to 64-bit platform from 32-bit, and then installed libboost-filesystem1.40-dev. After that, I began to experience such errors. I have "never" come across such a compilation error before. Even though I completely removed libboost-filesystem1.40-dev afterwards to see if it causes the problem, nothing changed.
After migrating to 64-bit and installing libboost-filesystem1.40-dev, my application exhibited another "weird" behaviour such that it produced "hidden" files using mkdir() system call, which were previously created as regular ones on the filesystem. Can compiler options that I use cause such problems? Is it possible that libboost-filesystem1.40-dev overwrote some system libraries so that I am getting such errors ?
