I never used openwrt before but now I need to install gdbm package on openwrt. Could you please suggest me how to do it.
Make is not working on openwrt
Downloading gdbm sources and compiling them is giving me when configuring
configure: error: in /HDD/gdbm-1.13':
configure: error: C compiler cannot create executables
Seeconfig.log' for more details
Please help me
Follow the openwrt guide to get and build the openwrt from source
In make menuconfig, select the gdbm package and then start the compilation. It's pretty simple.

So I'm getting this error when attempting to install OpenCV on my computer.
'pkg-config' is not recognized as an internal or external command
I've been searching around for this pkg-config package and I can't seem to find a proper download source anywhere.
The only one I did find was pkg-config-lite. I tired to see if that one would work but no luck.
The original pkg-config release is available here:
http://www.freedesktop.org/wiki/Software/pkg-config
I'm attempting to get google's ios webkit debug proxy working on my laptop, running ubuntu 15.04.
https://github.com/google/ios-webkit-debug-proxy
I've followed their installation instructions as best I could. However, I'm new to both web development and linux and am having trouble at the step where I run ./autogen.sh.
It runs its checks for a while, but then I receive the following error from the terminal:
checking for libimobiledevice... no
configure: error: Package requirements (libimobiledevice-1.0 >= 1.2.0) were not met:
Requested 'libimobiledevice-1.0 >= 1.2.0' but version of libimobiledevice is 1.1.6
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables libimobiledevice_CFLAGS
and libimobiledevice_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
I've tried my luck with troubleshooting this on my own but can't figure it out.
Anyone out there familiar with this error and what it wants me to do? Is my file-path messed up or do I need a different version of libimobiledevice (which I believe I have the most updated one)?
As the error says, you need libimobiledevice 1.2 or higher. Compiling it from source is a solution:
Download libimobiledevice 1.2: http://www.libimobiledevice.org/downloads/libimobiledevice-1.2.0.tar.bz2
Extract: tar xf libimobiledevice-1.2.0.tar.bz2
cd libimobiledevice-1.2.0
./configure
make
sudo make install
You should now be able to successfully build ios-webkit-debug-proxy.
You may need to run sudo ldconfig afterwards to update the library cache.
I'm trying to install OpenCV in Ubuntu 14.10 according to instruction.
I installed all mentioned dependencies, but when I'm trying to run make I get such errors:
/home/ilia/opencv-2.4.8/modules/highgui/src/ffmpeg_codecs.hpp:114:7: error: ‘CODEC_ID_H261’ was not declared in this scope
{ CODEC_ID_H261, MKTAG('H', '2', '6', '1') }
for all codecs, as I think.
And these errors:

It looks like it can not find some header files, but I installed all necessary dev packages
libswscale-dev, libavdevice-dev, libavfilter-dev, libavformat-dev, libavcodec-dev. What should I do to resolve these problems?
Installing OpenCV from the Ubuntu repositories is a good choice for the most cases, but sometimes you need build OpenCV from sources yourself.
For example, if you need OpenCV's non-free functionality, or want to contribute to this project (you should use the latest version to create pull request), or want to change something (yes, OpenCV can also contain bugs).
Possible solution is building ffmpeg (it's rather simple) - I really don't understand why Debian/Ubuntu prefers libav without alternative.
For installing ffmpeg you should download its sources from official site or clone GIT repository (git://source.ffmpeg.org/ffmpeg.git), then enter source directory and run
./configure --enable-shared --disable-static
make
sudo make install
you can also add other parameters to configure.
You can build static libraries too, but OpenCV can't be built with static ffmpeg libraries (now I don't know why).
After this you can download OpenCV sources from OpenCV site or clone GitHub repository (OpenCV repository), create build folder and run from it the following:
cmake PATH_TO_SOURCES -DCMAKE_BUILD_TYPE=Release
make
sudo make install
Of course, PATH_TO_SOURCES must be actual path to your OpenCV sources.
After these steps you have working latest OpenCV build in your system.
Unless you have special reasons I would suggest installing the OpenCV that are already in the Ubuntu repository: sudo apt-get install libopencv-dev
For video codecs I suggest simply trying to install all ffmpeg and gstreamer related codec packages.
You can try to build without a ffmpeg:
cmake -DCMAKE_BUILD_TYPE=RELEASE -DWITH_FFMPEG=OFF ..
make
sudo make install
I was trying to install WireShark 1.10.5 in linux.I was following the instructions provided with the software. Now,I am having problems while installing. It says pod2man cannot be found. How can i fix this?
checking for pod2man... no
configure: error: I couldn't find pod2man; make sure it's installed and in your path
try
apt-get install perl-modules
According to FOSSology bug 5619:
the pod2man utility which is used by the build process has been moved to a different package in Fedora 19 called perl-podlators
In previous versions it was in the package perl
so it appears you need to install the package "perl-podlators" to get pod2man.
I am compiling a dependency for a project on Ubuntu 10.10, and instead of having it install to /usr/local by default, I am instead installing it to /tmp/stage/usr/local. How do I go about informing CMake of the location of this custom installed dependency when I call it to generate the build files for said project.
I am running CMake 2.8.1, and I have tried to set CMAKE_PREFIX_PATH on the cmake command line, like so
cmake -D CMAKE_PREFIX_PATH=/tmp/stage/usr/local
but this doesn't seem to make a difference - the project doesn't seem to detect the dependency.
Also, if it matters, the project in question is OpenCV 2.2, and the dependency in question is FFMPEG...
I figured out how to fix my problem, and trying to point CMake at the appropriate install location isn't the issue.
Apparently, CMake is unable to find the pkg-config files for FFMPEG (i.e. libavcodec.pc, libavdevice.pc, etc.) that tell it where the FFMPEG headers and libraries are located. In a typical install scenario, these files would be located at /usr/lib/pkgconfig. However because of the custom install location, they are instead located at /tmp/stage/usr/local/lib/pkgconfig.
So that CMake could find these files, I had to add the following environment variable:
export PKG_CONFIG_PATH=/tmp/stage/usr/local/lib/pkgconfig
After which point, OpenCV built against FFMPEG as expected.
