attempting to build the new 2.x branch on OSX - some notes...

[davidbuzz]

get a few dependancies first:

brew install gtkmm gtk+ gtkglext cmake glib glade

you'll also need to manually download , compile and install the latest versions of libtool, autoconf and make:

wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.68.tar.gz
wget http://ftp.gnu.org/gnu/libtool/libtool-2.4.tar.gz
wget http://ftp.gnu.org/gnu/make/make-3.82.tar.gz
( extract each of these to a folder, cd to it, type: ./configure ; make ; sudo make install )

these above tools are ( by default) installed into /usr/local, so you need to have /usr/local/bin in your PATH variable, before /usr/bin etc:

set PATH=/usr/local/bin:$PATH

you'll also need to tweak the code so it doesn't refer to GL/gl.h or GL/glu.h

edit this file:
vi src/stdafx.h
and change the two GL related #includes near the top to:
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>

then type :
aclocal
automake
sh autogen.sh

I'm not sure what else is needed, as I kinda hacked around a bit. Eg: I installed freeglut, but I don't thnk it's needed. Anyway, I downloaded it from here: http://aarnet.dl.sourceforge.net/project/freeglut/freeglut/freeglut-2.6.0.tar.gz and I found that this configure line works for it: ./configure --x-includes=/usr/X11/include --x-libraries=/usr/X11/lib

still working on it, so I'll add comments to this ticket if /when it all comes together. :-)

[davidbuzz]

the correct #includes on OSX are OpenGL/gl.h and OpenGL/glu.h , just a clarification on the above issue.

[davidbuzz]

a few further notes:
once I got the autogen.sh running to a point where it created a ./configure script ( and then ran it, and it barfed), I manually edited the ./configure script and removed the offending lines:
#IT_PROG_INTLTOOL(0.26)
and
#PKG_PROG_PKG_CONFIG(0.22)
#PKG_CHECK_MODULES(GTKMM, gobject-2.0 glib-2.0 gtkmm-2.4 gtkglext-1.0 gtk+-2.0)

and this meant I was able to get the configure script to run to completion, creating me some Makefile/s ( which were a bit broken ).

I found that the Makefile/s ( in root, an in ./src folder ) were unable to complete because they couldn't find gtkmm and gtkglext-1.0 , so I manually edited these files and took the output from "pkg-config --cflags gtkmm-2.4" and "pkg-config --cflags gtkglext-1.0" and added the output to the CFLAGS = xxx lines of hte makefile. I also aded the output of "pkg-config --libs gtkmm-2.4" and "pkg-config --libs gtkglext-1.0" to the LIBS = xxx lines of hte makefiles too.

for me, the resulting CFLAGS line was:
CFLAGS = -g -O2 -D_REENTRANT -I/opt/homebrew/Cellar/gtkmm/2.18.2/include/gtkmm-2.4 -I/opt/homebrew/Cellar/gtkmm/2.18.2/lib/gtkmm-2.4/include -I/opt/homebrew/Cellar/glibmm/2.22.2/include/giomm-2.4 -I/opt/homebrew/Cellar/glibmm/2.22.2/lib/giomm-2.4/include -I/opt/homebrew/Cellar/pangomm/2.26.2/include/pangomm-1.4 -I/opt/homebrew/Cellar/pangomm/2.26.2/lib/pangomm-1.4/include -I/opt/homebrew/Cellar/gtk+/2.24.4/include/gtk-2.0 -I/opt/homebrew/Cellar/gtk+/2.24.4/include/gtk-unix-print-2.0 -I/opt/homebrew/Cellar/gtkmm/2.18.2/include/atkmm-1.6 -I/opt/homebrew/Cellar/gtkmm/2.18.2/include/gdkmm-2.4 -I/opt/homebrew/Cellar/gtkmm/2.18.2/lib/gdkmm-2.4/include -I/opt/homebrew/Cellar/glibmm/2.22.2/include/glibmm-2.4 -I/opt/homebrew/Cellar/glibmm/2.22.2/lib/glibmm-2.4/include -I/opt/homebrew/Cellar/glib/2.28.8/include/glib-2.0 -I/opt/homebrew/Cellar/glib/2.28.8/lib/glib-2.0/include -I/opt/homebrew/Cellar/gettext/0.18.1.1/include -I/opt/homebrew/Cellar/glib/2.28.8/include -I/opt/homebrew/Cellar/libsigc++/2.2.9/include/sigc++-2.0 -I/opt/homebrew/Cellar/libsigc++/2.2.9/lib/sigc++-2.0/include -I/opt/homebrew/Cellar/cairomm/1.8.4/include/cairomm-1.0 -I/opt/homebrew/Cellar/cairomm/1.8.4/lib/cairomm-1.0/include -I/opt/homebrew/Cellar/pango/1.28.4/include/pango-1.0 -I/opt/homebrew/Cellar/libpng/1.2.44/include/libpng12 -I/opt/homebrew/Cellar/gtk+/2.24.4/lib/gtk-2.0/include -I/opt/homebrew/Cellar/atk/2.0.1/include/atk-1.0 -I/opt/homebrew/Cellar/gdk-pixbuf/2.22.1/include/gdk-pixbuf-2.0 -I/usr/X11/include/cairo -I/usr/X11/include/pixman-1 -I/usr/X11/include/freetype2 -I/usr/X11/include

and the resulting LIBS line was:
LIBS = -L/opt/homebrew/Cellar/gtkmm/2.18.2/lib -L/opt/homebrew/Cellar/glibmm/2.22.2/lib -L/opt/homebrew/Cellar/pangomm/2.26.2/lib -L/opt/homebrew/Cellar/gtk+/2.24.4/lib -L/opt/homebrew/Cellar/glib/2.28.8/lib -L/opt/homebrew/Cellar/gettext/0.18.1.1/lib -L/opt/homebrew/Cellar/libsigc++/2.2.9/lib -L/opt/homebrew/Cellar/cairomm/1.8.4/lib -L/opt/homebrew/Cellar/pango/1.28.4/lib -L/opt/homebrew/Cellar/atk/2.0.1/lib -L/opt/homebrew/Cellar/gdk-pixbuf/2.22.1/lib -L/opt/homebrew/Cellar/libpng/1.2.44/lib -L/usr/X11/lib -lgtkmm-2.4 -latkmm-1.6 -lgdkmm-2.4 -lgiomm-2.4 -lpangomm-1.4 -lgtk-x11-2.0 -lglibmm-2.4 -lcairomm-1.0 -lsigc-2.0 -lgdk-x11-2.0 -latk-1.0 -lgio-2.0 -lpangoft2-1.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lm -lcairo -lpng12 -lpango-1.0 -lfreetype -lfontconfig -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl

after that, it compiled and ran!

[mmeeks]

Wow ! :-) way cool ... so - this is really important work; thanks for it !
Are there any patches you could make to autogen.sh / or configure.in to improve the configure process on Mac ? or a patch to a README to help people get it building ?
Finally the 'libreprap' stuff (sadly) threw out a lot of cross-platform goodness, so I wonder if we manage to detect & use OS/X com-ports properly these days ... either way, fixes are very much welcome.

I guess you need pkg-config installed, and then you should get your link line to work nicely. I guess I should update autogen.sh to be the latest perl-script from libreoffice to do this piece that checks for pkg-config explicitly.

[davidbuzz]

I'm far from being the correct person to recommend changes to autogen.sh and/or configure.in. I honestly don't even know what these files do ( apart from somehow ending up making the configure script automagically for me). i'm happy to be a test bunny though ( davidbuzz AT gmail.com). My further experiments with the compiled app find that it has a lot of dynamic lib dependancies ( mostly on my libraries from homebrew) , and so it's currently non-portable to other mac's without an installer of some sort to copy the libraries too. I've tried bundling the needed .dylib files into a "repsnapper.app" bundle ( it's just a directory really), but unless or until I'm able to compile them all with "@executable_path" in them ( see http://qin.laya.com/tech_coding_help/dylib_linking.html ), then it's all very much a lost cause at this time. the other option is to static link all the libraries, which is also a lot of extra work. :-)

Buzz.

One of us needs to get access to a mac or frankmac for a day or two to test out this build script and integrate it, I guess.

Also, see Issue #25 #25

[davidbuzz]

thaytan:
I have ongoing access to a number of macs, and as I've said above, I'm happy to perform testing etc, and try to figure out why certain things don't work.... but I know less than nothing about autoconf and libtool, so anything further I do here ( beyond what I've already done above) will need more hand-holding, and someone to suggest some next move/s. Pls get in contact with me, eg: davidbuzz at gmail dot com, and I can probably arrange to get on IRC for a few hours at a mutually convenient time, and work through this with you or someone else.... ? Buzz.

[thaytan]

OK, I'll try and meet up with you sometime. We're in the same timezone give or take daylight savings, so it shouldn't be too hard to find a good time.

[mmeeks]

If you head to irc.freenode.net and the #repsnapper channel - there is usually someone available there if you make some noise, much of the day: :-)

[davidbuzz]

also, there are known issues with the OSX included libiconv , and the recommended practice is to build a more standard one at a different location, and then be sure to link agains the correct one - I'm not sure if this is totally essentialy for repsnapper though, might be able to get away without it:

As a result I installed libiconv from sources:
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar -zxvpg libiconv-1.14.tar.gz
cd libiconv-1.14
( this builds both 32 and 64 bit archithecture )

[mmeeks]

pushed the couple of changes above to master - it'd be great to document your OS/X building experience so others could follow that; if you could mail me a text file and/or patch to mmeeks@suse.com that'd be wonderful :-)

Thanks.

[davidbuzz]

to mmeeks, I thought that's what I was doing here.....? as for text file/patches, I'm not sure I have anything more to add at this point than what I've put here. For the short-term, I'll keep updating this ticket if I come across anything new. :-)

[davidbuzz]

these made my OSX buid finally work..... but have a high possibility of borking other platforms, please check for me.
