Note about CFLAGS & LDFLAGS
This may be helpful when you get errors during compiling source codes.
CFLAGS as environment variable sets PATH to include directory
LDFLAGS as environment variable sets PATH to lib directory
For example, adding another openssl from Homebrew to compile something:
CFLAGS="-I$(brew --prefix openssl)/include" LDFLAGS="-L$(brew --prefix openssl)/lib" make
This make you use specified openssl to make

recompile with -fPIC lib/mylib.o: could not read symbols: Bad value
I'm a sysadmin but I'm not a compiling expert at all. I faced up the error as reported in the title of this article and I felt confused; when the magic of compiling source code does not work it's like the nyancat starts floating in your head. I know that feel bros.
So I'm just here to share a good as the hell howto from the great gentoo community. Go and read it!
Finding a libre 2D molecule editor: success!
After much blood, sweat, and tears, I've finally gotten gnome-chemistry-utils running on Mac OS X. Yes, really. Previous tribulations [here](http://arklenna.tumblr.com/post/20832381661/finding-a-libre-2d-molecule-editor-part-2). I decided to not make a CMake project because I figured there wouldn't be Find scripts for most of the dependencies, and I eventually realized that everything I needed had a .pc somewhere. Major steps to getting it to find the dependencies: * I had to give pkg-config several paths: ``` $ echo $PKG_CONFIG_PATH :/usr/local/share/pkgconfig:/usr/local/lib/pkgconfig:/opt/local/share/pkgconfig:/opt/local/lib/pkgconfig ``` * goffice 0.9.2 compiled with `./configure -CFLAGS=-DG_CONST_RETURN=const`. This has been merged into Macports r91768. * Despite the fact that `GL/glx.h` is in `/opt/local/include` and `gtk+-3.0.pc` lists this as an include dir, gnome-chemistry-utils complained about not finding it. I looked in `configure.ac` and found the following gem: ``` dnl Not sure we need to test for glx.h AC_CHECK_HEADER(GL/glx.h,,[AC_MSG_ERROR([Error, GL/glx.h not found.])]) ``` I commented out the header check and, uh, it configured fine. (ran `aclocal; autoconf; ./configure`) * `make` threw the same type of errors goffice was throwing (about G_CONST_RETURN needing stuff before it), so I ended up using the following configure step for gnome-chemistry-utils: ``` $ ./configure CFLAGS=-DG_CONST_RETURN=const CXXFLAGS=-DG_CONST_RETURN=const ``` And I've got it running! A few hiccups with importing a molecule: after going to Tools/Import molecule, the Import window was behind the main window. XQuartz is always a bit wonky. In order to paste into the text box, I enabled 3-button mouse mode, and option-click/Paste appears to properly access the OS X copied text. I haven't fussed with it too much, but it seems much easier to use than BKchem. Now of course the question is whether I want to attempt to make a macport for this. The most horrifying part was getting chemical-mime-data to build. I don't know enough about autoconf to fix the png generation problem, and I don't even think chemical-mime-data helps OS X at all (I still got "unknown type" errors). I could remove it as a dependency and see if I can get gnome-chemistry-utils to build. P.S. Appears to crash when I try to save or quit. Hmm. ``` (gchempaint-0.14:33600): GLib-GIO-ERROR **: Settings schema 'org.gtk.Settings.FileChooser' is not installed ```
