error installing libgd in mac 10.9
circos, gd, libraries, macos, perl
Solution
I successfully installed it using homebrew. It was as simple as:
brew install gd
This installed lib-gd version 2.1.0_1.
Problem
I'm trying to install libgd on my mac OSX 10.9 following the instructions here (https://mikewest.org/2007/04/installing-libgd-from-source-on-os-x) and peaking on some more info here (Installing GD library for perl on MacOSX 10.6). the main goal is to be able to install and use Circos. i followed all the steps to install the various libraries libpgn, pibjpeg and freetype using mainly `./configure && make && make sudo install`...however 1) the `./congigure` command from libgd does not find the libraries that I just installed and what I get is the following: ``` ** Configuration summary for libgd 2.1.0: Support for Zlib: yes Support for PNG library: no Support for JPEG library: no Support for VPX library: no Support for TIFF library: no Support for Freetype 2.x library: no Support for Fontconfig library: no Support for Xpm library: no Support for pthreads: yes ``` i read the README file (yeeee) suggesting to use `--with-png=myDirectory --with-freetype=myDir` etc..i did that (not sure if it made a difference) but when I get to the `make` command I get the following error ``` Undefined symbols for architecture x86_64: "___sincos_stret", referenced from: _gdImageCopyRotated in gd.o _gdAffineRotate in gd_matrix.o _gdImageRotateNearestNeighbour in gd_interpolation.o _gdImageRotateGeneric in gd_interpolation.o _gdImageRotateBilinear in gd_interpolation.o _gdImageRotateBicubicFixed in gd_interpolation.o _filter_bessel in gd_interpolation.o ...
