My supervisor has asked that I install a fortran compiler on my mac and suggested using MacPorts to install gcc6. I have tried to install gcc6 a number of times but each time it doesn't seem to come with gfortran. No matter what I do I cannot seem to figure out what is going on and how to get around it.
Any hep on the matter would be greatly appreciated.
Here is the command used to install gcc:
sudo port install gcc6
MacPorts allows you to have multiple versions of gcc installed. Before you get gfortran executable you have to select the default version.
First - install gcc:
sudo port install gcc9
After this command you will have gfortran under gfortran-mp-9 alias. To make gfortran-mp-9 the default and make it reachable via gfortran command do:
sudo port select --set gcc mp-gcc9
The examples above assumed gcc9, but you might need adjust the above gcc version to the one you need to work with.
With macports the correct command to install fortran would be
sudo port install gcc6 +gfortran
This will install gfortran. You may want to refer to the gfortran manual along with other Fortran references you may be using.
Note: You may choose some other version of gcc, of course. You can search for which versions are available on the macports site.

I have OSX 10.10.5 with Octave 3.4.0 running (installed, who knows how, I did it a million different ways through port, file extraction, ftp, homebrew…). I tried to update my Programme (brew install octave or sudo port install octave) and Terminal spits out:
Warning: octave-3.8.2 already installed, it's just not linked
Okay, great. So I have a better programme somewhere installed. What now? How on earth am I supposed to “just link” the newer installation?
If you install octave with Homebrew and it doesn't link it it should tell you why. You can force Homebrew to link octave with
$ brew link --overwrite octave
You can also add the --dry-run option to check and see what Homebrew will do to link octave
$ brew link --overwrite --dry-run octave
A possible reason for Homebrew not linking octave is that you've installed it by another method, MacPorts for instance. It is not recommended that you use both Homebrew and MacPorts on the same system.
Is there a way to change the compiler to gcc from clang? I have the command line tools installed and am trying to use the terminal to compile instead of xcode itself.
For MacPorts use:
port select --set gcc <group>, <version>
. . as detailed in this answer.
For Homebrew use:
Brew link and brew unlink the package versions that you prefer to use. Note that an "unlinked" package is still installed and usable from /usr/local/opt//, it's just not in the default path.
You can install gcc using any ports system (e.g., MacPorts, http://www.macports.org/)
This is my first time trying to compile source code in terminal (I installed gimp using macPorts but this could be part of the problem...?)
I want to install fontforge and I was following these instructions how to install fontforge.
I got this warning while installing brew:
Warning: The following *evil* dylibs exist in /usr/local/lib
They may break builds or worse. You should consider deleting them:
/usr/local/lib/libssl.0.9.8.dylib
I could not find usr/local/lib and the only libssl file was in opt/local/lib called libssl.1.0.0.dylib which is supposed to be hidden apparently...
I made it to the "brew install cairo --use-clang" step, then when I try the "brew install fontforge --use-gcc" step I get the following warning:
Warning: It appears you have MacPorts or Fink installed.
Software installed with other package managers causes known problems for
Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.

Error: GCC could not be found
when I check gcc version I get:
:~ me$ gcc --V
i686-apple-darwin11-llvm-gcc-4.2: no input files
Do I need to uninstall macports (then re-install gimp?)
I read gcc comes with xcode, I have xcode 4.3 (upgraded after this issue but didn't fix it) so do I have gcc or not? is there another way to check etc.
Can anyone tell me what I am doing wrong (what I broke etc)?
NOTE I also have flashbuilder which has a program called gcc as well (I dont know if this broke the other gcc...)
I have been trying to install the Ruby PG gem, but kept getting the "Failed to build gem native extension." error.
After sifting through a lot of google results, I tried nearly every recommendation I came across, all without luck. However, I believe I've tracked down the source of the problem ... Homebrew.
Homebrew installed PostgreSQL 9.0.4, but only with the 32-bit libraries. As I am running Snow Leopard (10.6.8) with XCode 3.26, I need the 64-bit libraries in order to compile everything without library mismatch errors. But I cannot seem to find out how to force Homebrew to install them, even with ARCHFLAGS and ENV set to "-arch x86_64".
Suggestions, please :)
p.s. I found out that I only had 32-bit libraries installed by running:
file /usr/local/Cellar/postgresql/9.0.4/lib/libpq.5.3.dylib
which returned:
/usr/local/Cellar/postgresql/9.0.4/lib/libpq.5.3.dylib: Mach-O dynamically linked shared library i386
Update: re-installed Homebrew, which installed postgresql/9.1.1 and 64-bit shared libraries.
But another problem emerged, while installing the PG gem. For some reason it was looking for ginstall in /opt/local/bin. As I had removed MacPorts, that directory was also removed. I did find this solution:
mkdir -p /opt/local/bin/
sudo ln -s /usr/bin/install /opt/local/bin/ginstall
And now everything seems to be working ....
So it looks like my first install, using Homebrew, must have been done with regular Leopard.
Removing the Homebrew "Cell" directory and all of its contents, running the install script again, then doing "brew install" and "brew update" with all needed packages, got me the latest version of PostgreSQL, with 64-bit developer library.
And creating the above symbolic link fixed any left over errors from the MacPorts removal.
Now all is well :)
I try download lighttpd 1.4.23 source, and compile it on MacOSX 10.5.5.
This is the error I am getting:
$ ./autogen.sh
./autogen.sh: running `libtoolize --copy --force'
./autogen.sh: line 19: libtoolize: command not found
I tried ask the same question on lighttpd forum, but I can't get any help there.
Thanks in advance.
libtoolize is part of GNU libtool, a package for building libraries portably. On the Mac, one option for getting it is to use MacPorts, a package manager which works in a similar fashion as Gentoo and FreeBSD, in that it compiles packages on your machine. See http://www.macports.org/install.php.
Beware, though, that it will be installed as glibtoolize, i.e. with a 'g' prefixed. That is a standard way to make GNU tools live in parallel with UNIX tools of the same name, that might be present (even though there isn't one in this particular case).
The command for installing libtool from MacPorts is: sudo port install libtool
Add a '-d' flag after the 'port' command to see the build output.
Here's what I use to install lighttpd 1.4.25 on Mac OS X 10.6.2. If I remember correctly, the same thing worked for me in a recent version of Mac OS X 10.5.
Install Xcode Developer Tools
Either install them from the DVD that came with your Mac (under Optional Installs) or download them from Apple's developer page.
Install PCRE
curl -O http://softlayer.dl.sourceforge.net/project/pcre/pcre/7.9/pcre-7.9.tar.gz
tar xzf pcre-7.9.tar.gz

tar xzf lighttpd-*.tar.gz
cd lighttpd-*
./configure
make && sudo make install
Note that the URLs above will quickly go out of date; you may need to download the latest versions of the .tar.gz packages from a different location.
