[SOLVED] Can't find package.

dellthinker · 08-27-2011, 11:35 AM

Hi all, I'm trying to find a package or program needed in order to finish a manual source install for this site. They have their own program so they have their own dependencies. When I try to build the program I encounter this error..

Quote:

make[1]: Entering directory `/home/user/Desktop/vpnclient'
ranlib libssl.a
ranlib libcrypto.a
ranlib vpnclient.a
gcc vpnclient.a -pthread -lrt -lm -lz libssl.a libcrypto.a -lpthread -ldl -lreadline -lcurses -o vpnclient
/usr/bin/ld: cannot find -lreadline
collect2: ld returned 1 exit status
make[1]: *** [vpnclient] Error 1
make[1]: Leaving directory `/home/user/Desktop/vpnclient'

So I did the following ...

Code:

computer:/home/user/Desktop/vpnclient# aptitude search lreadline
i   tclreadline                     - GNU Readline Extension for Tcl/Tk         
computer:/home/user/Desktop/vpnclient# apt-get install tclreadline

After install i tried to make build again and got the same error. Any suggestions? I really need this program installed so any help is appreciated. Thanks.

Just a note for future reference: when a compiler uses a specific library with option -l, the actual name of the library is always prefixed by lib followed by the name of the library. So the option -lreadline means the required library is

Code:

libreadline.so.*

where the suffix so means it is a shared object and the asterisk stats for the version number.

Thanks for that, I've always been curious what *.so files were. I just knew that there were important to have
