This option is best for users who like to develop their apps without using Apple's Xcode IDE.
|

Users should be comfortable with using `bash` or `tcsh` in a terminal window.

|

### Prerequisites
|
||||
|
||||
In order to build FLTK from the command line, you need to install the Xcode
|
||||
developer environment. It can be downloaded from the Apple Store for free.
|
||||
In order to build FLTK from the command line, you need to install a C++ compiler
|
||||
environment, `make` and `autoconf`. _Xcode_ is the easiest way to install all prerequisites,
|
||||
even if you don't plan to use it as your iDE.
|
||||
|
||||
After downloading and installing, you need to launch the Terminal. Terminal.app
|
||||
is located in the "Utilities" folder inside the "Applications" folder. I like
|
||||
to keep the Terminal in the Dock.
|
||||
_Xcode_ can be downloaded via the
|
||||
[App Store](https://itunes.apple.com/de/app/xcode/id497799835?l=en&mt=12).

After downloading and installing, you need to launch the Terminal. _Terminal.app_

|
||||
to keep the Terminal in the Dock for future use (launch Terminal, right-click or control-click
|
||||
on the Terminal icon that is now in the docking bar, and choose _Options_->_Keep in Dock_).
|

|

2.2 Downloading and Unpacking
|
||||
--------------------------------
|
||||
<a name="bam_download"></a>
|
||||
### Downloading and Unpacking
|
||||
|
||||
Download FLTK from here:
|
||||
FLTK 1.4 is currently (as of Jan. 2019) only available as a source code repository via GitHub.
|
||||
You will need to clone the repository to check out the source code onto your machine. This
|
||||
has the great benefit that the source code can be updated simly by telling _git_ to _pull_
|
||||
the newest release.
|
||||
|
||||
https://www.fltk.org/software.php
|
||||
|
||||
If you are familiar with Git and like to stay current with your version,
|
||||
you will find the Git access parameters at the bottom of that page.
|
||||
Unpack FLTK into a convenient location. I like to have everything in my
|
||||
dev directory:
|
||||
Start your terminal. If you have not set up a developer directory yet, I recomment to use
|
||||
`~/dev` and put all your projects there:
|
||||
|
||||
```bash
|
||||
cd
|
||||
# make sure we are in the home directory
|
||||
cd ~
|
||||
# create our developer directory and go there
|
||||
mkdir dev
|
||||
cd dev
|
||||
mv ~/Downloads/fltk-1.3.xxxx.tar.gz .
|
||||
tar xvfz fltk-1.3.xxxx.tar.gz
|
||||
cd fltk-1.3.xxxx
|
||||
```
|
||||
Now create a copy of the current source code locally:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/fltk/fltk.git fltk-1.4.git
|
||||
cd fltk-1.4.git
|
||||
```
|
||||
|
||||
If you got FLTK via Git then you need one extra step: build the
|
||||
configure script. Otherwise skip the following part marked ADVANCED:
|
||||
<a name="fltk-1.4.git"></a>
|
||||
### Configuring FLTK
|
||||
|
||||
Using you shell in the terminal, make sure that you are in the root directory of your
|
||||
FLTK source code tree.
|
||||
|
||||
2.3 Configuring FLTK
|
||||
-----------------------
|
||||
If you are configuring fltk for the first time, you need to instruct FLTK to create some
|
||||
very basic configuration files. Type:
|
||||
|
||||
```bash
|
||||
NOCONFIGURE=1 ./autogen.sh
|
||||
```
|
||||
This script may generate a few error messages which you can sefely ignore.
|
||||
|
||||
Now configure your FLTK installation: stay in your FLTK source-code directory
|
||||
and type
|
||||
|
||||
./configure
|
||||
```bash
|
||||
./configure
|
||||
```
|
||||
|
||||
ADVANCED: type "./configure --help" to get a complete list of optional
|
||||
configurations parameters. These should be pretty self-explanatory. Some
|
||||
more details can be found in README.
|
||||
The configuration script runs a number of tests to find libraries and tools. The configuration
|
||||
summary should not show any errors. You can now continue to build FLTK.
|
||||
|
||||
To create multi-architecture binaries, start "configure" with these flags:
|
||||
./configure --with-archflags="-arch i386 -arch x86_64"
|
||||
For the advanced user, there are a few more optinons to the _configure_ script. Type
|
||||
`./configure --help` to get a complete list of options. These should be pretty
|
||||
self-explanatory. Some more details can be found in
|
||||
[online documentation](https://www.fltk.org/doc-1.4/intro.html#intro_unix).
|
||||
|
||||
To create applications that can run under macOS 10.4 and above, use these flags:
|
||||
./configure CXXFLAGS="-mmacosx-version-min=10.4" LDFLAGS="-mmacosx-version-min=10.4"
|
||||
<a name="bam_build"></a>
|
||||
### Building FLTK
|
||||
|
||||
:END_ADVANCED
|
||||
Now this is easy if all the previous steps were successful. Stay in your FLTK source-code
|
||||
directory and type:
|
||||
|
||||
The configuration script will check your machine for the required resources
|
||||
which should all have been part of your Xcode installation. Review the
|
||||
Configuration Summary, maybe take some notes.
|
||||
|
||||
|
||||
2.4 Building FLTK
|
||||
--------------------
|
||||
|
||||
Now this is easy. Stay in your FLTK source-code directory and type:
|
||||
|
||||
make
|
||||
```bash
|
||||
make
|
||||
```
|
||||
|
||||
The entire FLTK toolkit including many test programs will be built for you. No
|
||||
warnings should appear, but "ranlib" may complain about a few modules having no
|
||||
symbols. This is normal and can safely be ignored.
|
||||
|
||||

|
||||
### Testing FLTK
|
||||
|
||||
2.5 Testing FLTK
|
||||
-------------------
|
||||
After a successful build, you can test FLTK's capabilities by running
|
||||
|
||||
After a successful build, you can test FLTK's capabilities:
|
||||
```bash
|
||||
test/demo
|
||||
```
|
||||
|
||||
test/demo
|
||||
|
||||
|
||||
2.6 Installing FLTK
|
||||
----------------------
|
||||
<a name="bam_install"></a>
|
||||
### Installing FLTK
|
||||
|
||||
If you did not change any of the configuration settings, FLTK will be installed
|
||||
in "/usr/local/include" and "/usr/local/lib" by typing
|
||||
in `/usr/local/include`, `/usr/local/lib`, and `/usr/local/bin` by typing
|
||||
|
||||
sudo make install
|
||||
```bash
|
||||
sudo make install
|
||||
```
|
||||
|
||||
It is possible to install FLTK without superuser privileges by changing the
|
||||
installation path to a location within the user account by adding the
|
||||
"--prefix=PREFIX" parameter to the "./configure" command.
|
||||
`--prefix=PREFIX` parameter to the `./configure` command.

|
||||
FLTK provides a neat script named `fltk-config` that can provide all the flags
|
||||
needed to build FLTK applications using the same flags that were used to build
|
||||
the library itself. Architecture flags (e.g., -arch i386) used to build the
|
||||
library, though, are not provided by the fltk-config script. This allows to
|
||||
build universal libraries and to produce applications of any architecture
|
||||
from them. Running "fltk-config" without arguments will print a list
|
||||
the library itself. Running `fltk-config` without arguments will print a list
|
||||
of options. The easiest call to compile an FLTK application from a single source
|
||||
file is:
|
||||
|
||||
fltk-config --compile myProgram.cxx
|
||||
```bash
|
||||
fltk-config --compile myProgram.cxx
|
||||
```
|
||||
|
||||
"fltk-config" and "fluid" will be installed in "/usr/local/bin/" by default. I
|
||||
recommend that you add it to the command search path.
|
||||
`fltk-config` and our user interface designer `fluid` will be installed in
|
||||
`/usr/local/bin/` by default. I recommend that you add this directory to the shell
|
||||
`PATH` variable.
