Guys im curious what linux package do i need to compile a program with -l crypt? I cant seem to find it with bing and the source im trying to compile seems to need -lcrypt but i dont know what package im looking for help me out. Specifically im using cygwin.

might be a stupid question cause im using cygwin but just thought i would ask here because i cant find it on the web.

I am not a cygwin user so totally unfamiliar with what it provides, but you should be able to answer most questions about include files and linking from the man page.

If cygwin includes man pages see man crypt, or find it online here.

Usually the name of libs recognized by the linker are used without the 'lib' prefix so -lcrypt would imply libcrypt. Some like libmath may recogize abbreviations such as -lm as well.

Good luck!

UPDATE: I see you found the answer while I was updating my reply!

If your issue is solved please use the Thread Tools link above top post to make this question as SOLVED! Thanks!

i just found it sorry for the bother the package was libcrypt()

actually that didn't work installing that package but i moved on, is there a way to delete this forum post?

What error message are you getting when you compile or link? (i.e. is the compiler failing or is the linker failing?)

Be sure to #include <unistd.h> in your source and check whether any feature test macros may be required for the functions you are using.

Re post removal: Once a question has had multiple views and/or replies they are not normally removed as that is potentially disrespectful of the time others may have spent considering the question.

Perhaps I don't understand, but this is just wrong.
You need to compile any app with -l crypt if that app needs it. And this information is available [usually] in the documentation of that app.
What do you want to compile at all?

General policy is not to delete old posts.

The correct package name is probably libcrypt-devel or something like that; usually package managers separate out the stuff required to compile in order to save bandwidth/space.

Can be distribution-dependent. Ubuntu: libc6-dev, Centos: glibc-devel, Cygwin: libcrypt-devel
