Manpages for Linux Development

]]> This year I’m taking a course in Operating Systems, and it looks like I’m loving this area. I’m going to post here problems I face during the course, and their solutions, so I can find them easily next time I need them. As a side effect, I’ll be sharing them with the world. ;) The first problem I faced is with the manpages: Sections 2 and 3 of the man pages are necessary for development on Linux: Section 2 is about system calls, and section 3 is about library calls. These two sections do not come with the default Ubuntu installation (after all, Ububtu is for human beings!). So I was surprised when I typed “man 2 sigaction” and got this message:

No manual entry for sigaction in section 2

After some investigation/googling I found the problem: I don’t have section 2 and section 3 in my Ubuntu. These sections are available in the “manpages-dev” package. So, to install them one should type this in terminal:

sudo apt-get install manpages-dev

That’s all. Now I have sections 2 and 3 and I’m happy. :)
