How to install libcurl?

[hakermania]

I mean I have installed all the packages I found on synaptic about curl and nothing...I cannot see any output in

pkg-config --libs curl

even after restart.


What is the accurate package to download?
Same thing with opencv....

Step 1: Have a look at an example source code for the libraries you want to use. Write down the name of a file you need (without path), e.g., "curl.h"

Step 2: Go to http://packages.ubuntu.com and under "Search the contents of packages", type in the file name. Hit the search button.

Step 3: Observe in which packages you can find the files. Which package names look correct? Install these packages.

Note that for curl, there seem to be three versions. Google for details why this is the case and then pick the package appropriately.

Also note that not all libraries support pkg-config. In that case, you will need to provide the include paths and library details manually to the compiler and linker.

Try "libcurl" instead of "curl":

pkg-config --libs libcurl

Should I feel like an idiot now ?

I was having the same problem while trying to install the patron gem, and the following solved it for me:

`apt-get install libcurl4-gnutls-dev'

Thanks mltsy, installing this let me install biomaRt (R bioconductor package) in Ubuntu 11.10 (also had to install libxml2).
