| fedora | we're now getting started. | |
|---|---|---|
| fedora | Speaker is Itamar Preis Peixoto | |
| fedora | RPM is a compressed file with metadata information. 99% of Fedora software is delivered in RPM format. | |
| fedora | It's a hands-on talk, if you have your laptop and would like to try it's OK. | |
| fedora | required software | |
| fedora | Most people start talking about writing a spec file, but we'll start talking about the source code and at the end you'll have an RPM file. | |
| fedora | development tools required | |
| fedora | gcc glibc-devel automake autoconf rpmdevtools mc gedit (or other text editor) | |
| fedora | (Pause while people install software...) | |
| fedora | next we're going to write a Hello World program | |
| fedora | source code follows | |
| fedora | #include <stdio.h> | |
| fedora | int main(){ | |
| fedora | printf("Fedora Flock 2013\n"); | |
| fedora | return 0; | |
| fedora | } | |
| * number80 (~80@fedora/number80) has joined | ||
| fedora | save this as flock.c | |
| fedora | to compile we'll use gcc | |
| fedora | gcc flock.c | |
| fedora | you'll have the program with the name a.out | |
| fedora | you can run it with ./a.out | |
| fedora | should show "Welcome to Flock" | |
| fedora | or "Fedora Flock 2013" if you followed what I typed... | |
| * qwebirc2558 (9909a8fa@gateway/web/freenode/ip.153.9.168.250) has joined | ||
| fedora | now we're going to write a readme.txt file | |
| fedora | save the readme.txt file | |
| fedora | next we're going to use GNU autotools | |
| fedora | first run "autoscan" | |
| fedora | (this is in the "flock" directory where you have the flock.c and a.out files) | |
| fedora | autoscan will create some files, the most important is configure.scan | |
| fedora | going to rename that to configure.ac | |
| fedora | question: does autoscan recurse directories? | |
| fedora | speaker: "I don't remember now." | |
| fedora | open configure.ac with your text editor | |
| * qwebirc2558 has quit (Client Quit) | ||
| fedora | going to change the FULL-PACKAGE-NAME to flock, change VERSION to 1.0, and leave BUG-REPORT-ADDRESS as-is | |
| fedora | save the file | |
| fedora | now run "autoheader" | |
| fedora | now we're going to create a makefile with gnu autotools | |
| fedora | vim Makefile.am | |
| fedora | (first letter must be uppercase) | |
| fedora | in the file | |
| fedora | bin_PROGRAMS=flock | |
| fedora | flock_SOURCES=flock.c | |
| fedora | now you're going to run "autoreconf -fiv" | |
| fedora | make dist | |
| fedora | (note that you can use make dist-zip to create zipfiles for other OSes, but that's not necessary for RPMs) | |
| fedora | can use make to compile, make clean to remove artifacts... | |
| fedora | rpmdev-newspec flock | |
| fedora | will create an empty file (spec) for us | |
| fedora | open flock.spec w/your text editor | |
| fedora | now you need to fill in the "form" with version, summary, | |
| fedora | group = x | |
| fedora | license = gpl | |
| fedora | source0: flock-1.0.tar.gz | |
| fedora | BuildRequires: can be left empty | |
| fedora | rpmbuiild -ba flock.spec | |
| fedora | (Might get an error b/c the source code is not in the right directory.) | |
| fedora | you need to have the flock-1.0.tar.gz file in rpmbuild/SOURCES/ | |
| fedora | under your home directory | |
| fedora | so: /home/user/rpmbuild/SOURCES/ | |
| fedora | another error b/c the spec file needs to have the files it creates listed under the %files | |
| fedora | after all that's correct, you'll run rpmbuild and you'll get an exit 0 | |
| fedora | "in less than 5 minutes we created an RPM" when we process the spec file with rpmbuild, it saves two files, one is the .src and one is the RPM | |
| mizmo | is zodbot on | |
| mizmo | zodbot, #startmeeting | |
| fedora | argh | |
| fedora | sorry | |
| fedora | :-( | |
| mizmo | its okay | |
| fedora | we're just wrapping this one up. I can save the log | |
