In linking a library in using GCC.
I am compiling Pro*C code.
When the maKe file start compiling if prints following :
Code:
I tried different options but unable to find the reason why it is not linking the libraries correctly.
I have a simple C program which uses ncurses library and I am having linker issues and couldn't get the program to link.
[Code]...
So I think the ncurses libraries are in place but gcc still couldn't link. I am totally stumped.
I am trying to compile a software using a provided sdk. I suspect that the sdk has some mismatch of the platform library, but I am not sure.
The error I got is
Code:
The libidata.so.42 is there in that folder. I guess the file might be in a big endian. Is there a way to check if the libidata.so.42 i have might be a big endian format, rather than little endian?
If my guess is incorrect, This is a c++ code on fedora x86 machine.
I am having some trouble when I try to link my custom libraries to target executables. There are two libraries
liba
libb
and an executable exec based on main.o The library libb has some reference to liba. Now if I put the libraries in same directories, I can compile the code as g++ -o exec main.o liba.a libb.a But, if I put the libraries in different directories, say d1 and d2, and use the command as g++ -o exec main.o d1/liba.a d2/libb.a I get an error as undefined reference to some function in liba. I am not sure if I am missing some thing in linking process. Also, if libb doesnot refer any functions in liba, there is no error in either of the case.
I am using a arm compiler to build my program but getting following compiler error at the end -
init.c.text+0x2c): undefined reference to '__libc_csu_fini'
init.c.text+0x34): undefined reference to '__libc_csu_init'
I first found something called lds(linker script) file.
And now I am willing to do a test with __attribute__((section)) to make a function stay in a private section. Sounds fun to me.
Part of my source code looks like this
By objdump, I didn't find a section called "my_own".
I need to compile a program and make it portable to other computers, but it needs some external libraries and I don't want them to be linked dynamically, I would like to compile them as one single executable or at least compile them in the same directory as the main output files. The program is sphinx>, it has its own configure and make scripts. I know I can run g++ with the -static flag, but I don't know how to do this with make or configure. This is the ./configure --help output

I am getting a linker error for a simple program to represent a singleton class.
Find below the program which I have written:
I did a ./configure and make and got this returned about 1/2 hr later:
Code:
undefined reference to `glDisable'
undefined reference to `glDisable'
undefined reference to `glutKeyboardFunc'
undefined reference to `glutSpecialFunc'
undefined reference to `glReshapeFunc'
And the oddest part is.... I passed --disable-gl to configure!
Recently I have downloaded TBB and I want to run a program using its libraries. But I encountered the following error: Linker: fatal error LNK1104: cannot open file 'tbb_debug.lib'
View 1 Replies View RelatedIn the ordering of files I keep I need links to directories. Sometimes I even need to move directories to new locations. I have tried using symlinks, but they become dead when I move the directory they point to. I have tried hard links, but I haven't found any Linux file system that would support hard linked directories. How can I achieve that a complex structure of directories (currently with symlinks for directories and hard links for files) keep symlinks live when directories are moved?
- is there any utility that updates symlinks when a directory is moved?
- is there any Linux filesystem that supports hard linked directories?
- is there any good Linux interface to the new NTFS (the only file system I know to support automatically updating directory links, called directory junctions)?
I am facing some problems when i am trying to link using g++. The linker error text is "undefined reference to `std::vector<std::string, std::allocator<std::string> >::end()'"

Upon rebooting, the message "ata4.01: failed to resume link(SControl 0)" appears and it does not proceed to boot after this. I booted an older kernel and the message is still there, but it does proceed to gdm after it shows up. unable to find something with this exact problem.
View 3 Replies View RelatedI want to ask, what should my computer look like if I plan to compile and run the linux kernel a lot? I mean what kind of hardware would someone recommend I use. Also is there a way I can fix this and maybe speed up the compile process. I tried make again and memory was again exhausted.

I have tried ln -s /lib/systemd/system/multi user.target /etc/systemd/system/default.target
And get the following error ln: failed to create symbolic link `/etc/systemd/system/default.target': File exists
I have even tried changing the /etc/systemd/system/default.target to my multi-user.target file to no aval.
I have a desktop that has a d-link DWL-520 wireless card, which was working under Windoze. Today I installed Centos 5.4 on the system , which went cleanly. I then used Network Configuration to set up the wireless card. I specified to use DHCP, set the SSID and authentication password. When I tried to activate the card I get these error messages
Error for wireless request "Set Mode" (8B06): SET failed on device wlan0 ; Operation not supported. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0.
The hardware manager seems to have correctly identified the card and chipset, (Intersil Prism 2.5) and installed driver hostap_pci which came with the distro. This web site seems to suggest that this is the correct driver: [URL] searching forums I've found a few references to these errors, but they were from several years ago, and for different distros and cards. I did find a reference to using Network Manager to configure the card instead of Network Configuration. I started the NM service and configured a connection using it instead, but still no luck.

I decided, as a project of mine, to create a small computer that could link up to a small display. Because the computer is very low-powered, guess what OS I decided to use? Linux... Ubuntu to be specific.Anyway, I come from using Xcode on OSX (very user-friendly compiler) and some tools for GUI and scripting development. That's where the problem comes in.I know C++, but I do not know how specifically Linux handles programming. I have the GCC compiler installed, and I know the terminal command to compile, but I have a few questions:
1. How do I link to different APIs (like OpenGL)
2. When I compile multiple files, do I compile the main .cpp/.cc file? Or is there a project file I use.
3. Is there a way to make GUIs easily in Linux? I was looking at the 'QT 4' tools.
4. What do the 'QT 4' tools do specifically?
5. Any good IDE? I am using 'Kate' at the moment, but I am not sure how it compares to other programs.
6. Any other tips? Pitfalls to watch out for? Hints to program quicker? Other software I could use?
I have made a very simple program in SDL that draws one image four times on a window.However I wanted it to be statically linked so the end user wouldn't have to install SDL and SDL-image in order to get the program working.

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

I never had to use anything more than -l , -lm , -c ,-o.It was only through dev documentation that I came across glib. Now I want to to compile and link a program with glib.

I need to make a link that goes absolutely nowhere, since it has an onclick event that uses javascript to show/hide content. It needs to look like a standard link and the mouse needs to change to the finger cursor like a standard link.
The following all don't work:
Code:
<a href="#" onclick="show_element('jetshop')">Read more...</a>
- moves to the top of the page.
<a href="" onclick="show_element('jetshop')">Read more...</a>

I would like to make gcc to link one lib (pthread in the example) statically, and the rest dynamically.
(See the example .c file at the end of this post.)
compiles fine, but every lib is linked dynamically.
Now every lib is linked statically
Not a dynamic executable
I would like to link the libpthread statically and the rest dynamically. Is it possible?
[url]says if I give the full path to the .a lib then it will be linked statically:
So for me it does not work.
On other sites I found that I should use -Wl,-Bstatic -lpthread -Wl,-Bdynamic, but it also doesn't work:
So, how can I do that?

As an example I used a little demo program from [url]
Here is the code:
Consider that symbolic links at times can be broken. The target reference can be lost or misplaced. As such, usage of a symbolic link becomes deterred or broken. I propose the following: Symbolic links from now on carry a checksum relating to the original file they are linked to. The original file will carry a property that checks if it has been changed. This property will figure out the new checksum, reconfigure the symbolic link, and continue the symbolic link. Furthermore, if the system were to change, there would exist the possibility of have a symblink-comparison feature that allows the user to check the entire filesystem for files that meet the checksum criteria so that symbolic links can once more be re-established.

I have a file called sitemapindex.xml
Its contents just are names of the other sitemaps. Google gets pissy because it isn't in a http:// format.
So, I need "<loc>sitemap-c1mediawiki-............</loc>" to be replaced with "<loc>http://domain.tld/sitemap-c1mediawiki-............</loc>".
Here's the expression I've been trying:
find /path/to/site/sitemap-index-c1mediawiki* -type f | xargs sed -i 's/[<loc>sitemap]/[<loc>http://domain.tld/]/'
It fails.
I've tried with and without brackets.
