I'm trying to compile a package and right at the ./configure step, I get :

checking for LIBCURL... configure: error: Package requirements (libcurl >=  7.15.4) were not met:



No package 'libcurl' found



Consider adjusting the PKG_CONFIG_PATH environment variable if you

installed software in a non-standard prefix.



Alternatively, you may set the environment variables LIBCURL_CFLAGS

and LIBCURL_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

What should I do ?

It seems that you should install development package version (this means headers) of libcurl with:

sudo apt-get install libcurl4-openssl-dev

Also make sure that you have installed pkg-config. If unsure install it with:

sudo apt-get install pkg-config
