Oh no, there's been an error

See Deploying Your Application for more information. You can drag and drop Disk Utility on the dock. Use Script Editor to edit, compile and run AppleScript files. Use osascript to execute an AppleScript command or file from the command line or from a script file. For more information, enter man:osascript in Safari once you have Sogudi installed see above. Here are some equivalents. For more information about a command, enter man: command in Safari once you have Sogudi installed see above. Many software projects use external libraries to complement their functionality. If one of these libraries is utilized, one should simply add the corresponding import unit to the uses clause and start using the library.

To use other open source libraries which aren't included with Mac OS X, the easiest way is by grabbing a pre-compiled library from the application bundle of popular open source applications.

FreeType for example is included inside the application bundle from Gimp in the path Gimp. Another option is downloading the source code from the library and building it manually, but compiling a C library is usually an unpleasant task for Pascal developers. So, again in the previous example, let's say that an application requires the FreeType library. One can grab the libfreetype. To properly link the application the Free Pascal command line option "-Fl..

The linker will then find the library in this location and read the install path which is written inside it. At runtime the linker will search for the library in this install path. It can be utilized with the following command line command:. It should return the written path. When building the application bundle, we should copy the libfreetype. Now the application can be built, the bundle and be built and then the application can be run and it will load the library correctly from the application bundle. For using libraries, which were installed using fink, you need to add the path to the libraries.

The resulting application is fine for distribution with fink, but in order to run without fink, you have to make a "standalone" version. There are several possibilities to achieve this, one of them will be outlined here: First copy the. Beware of the fact that the libraries can itself call libraries from fink. You have to adjust them as well. Another important point of libraries from fink is, that they have only one architecture, i. For a universal application, you have to combine single architecture libraries with lipo.

This provides a wealth of information detailing system hardware which can be useful when debugging user issues or simply optimising your application eg to take advantage of threads on multi-core CPU systems. Lazarus will create an application tuned for a single CPU. With the carbon version of the lcl, this is either PowerPC or Intel i 32bit.

You may want to distribute your application as a 'Universal Binary', allowing users that may have either a PowerPC or Intel computer to use the program. Next, you need to stitch these two executables together using the OS X program "lipo" installed with the other OS X developer tools required by Lazarus. For example, consider two versions of the application 'myprogram'. You can then combine these two to a univeral application by running this command:.

Before macOS Sierra users had the option to allow the installation of applications from "anywhere", "the App Store" and "identified developers". From macOS Sierra on, the "anywhere" option was removed. Thereafter, clicking on an application to run it results in a scary dialog being presented to your users stating: "YourApp can't be opened because it is from an unidentified developer.

Your security preferences allow installations of only apps from the App Store and identified developers". The only dialog option is to close it. Users can still run your application, but they have to know they can right-click or control-click on your application and then they get another scary dialog stating "YourApp is from an unidentified developer. Are you sure you want to open it?

Thanks for helping keep SourceForge clean.

Beginning with macOS Mojave This software needs to be updated. Contact the developer for more information.

Beginning with macOS Catalina If your application is not notarised, your users get the very scary dialog stating: "YourApp can't be opened because Apple cannot check it for malicious software. The steps to notarize an application are described in the article Notarization for macOS They can be initialised in three ways. In FPC 2. This unit is not available in older versions of FPC. Adding the clocale unit to the uses clause will cause the locale settings to be initialised using the configuration set at the Unix layer of OS X based on the LANG and related environment variables.

This unit is also available on other Unix-like platforms. If the procedure GetMacDateFormats is called in the beginning of the program's main unit the "International" settings of systems preferences are used. In each Mac application there is a main menu item with the name of the application. Lazarus will automatically add the "Services", "Hide" and "Quit" menu items to this menu.

By default your application name will be the name of your project.

You can rename your project, but you cannot add a space to the project name. Your application dock icon will also display "MyApp". Fear not, this can be fixed by editing the application Info. For example:. Copy the. For example, from the command line:. This bug has been fixed in Xcode 4. You can work around the bug in Xcode 3.

The Xcode integration kit is provided as an optional install to allow for developing with Free Pascal directly from Xcode. It is not required for development with Lazarus, however. Xcode 2.

Installing Lazarus on MacOS X

Please refer to the following table in order to find the correct version for your development environment:. Lazarus 1. Compiling from source required. Download the three disk images. If you receive a "Can't find unit Interfaces used by Project1" error on trying to compile a blank form, check the following settings in Lazarus should be set by default :. Note - different versions of Lazarus depend on particular versions of the FreePascal compiler and will not work with other versions. To obtain the up-to-date release versions of lazarus 1.

The extra bonus of fink is easy installation as well as clean removal of a huge number of other open source software packages, including FreePascal crosscompilers for other processors and systems. The choice for lazarus is between an Aqua look of lazarus preferred by most , a gtk2 look and a Qt4-based version:. This also installs a number of other packages, such as the FreePascal compiler, the lazarus sources, gtk2 libraries and more. At the prompt, whether you want to.

It really takes some time to build all packages, in particular on older Macs. Projects with the gtk1 widget set are also supported on On The support of PowerMacs has also been stopped with the release of lazarus 1. You need the latest stable released FPC installed in order to compile the development version. There are two development versions of the compiler: 2. The unstable version 2. Best is to download and install fpc 2.

Keep in mind that these are daily snapshots and that you can have bad luck and get a buggy version. The probability is about So if the version is buggy try another day or use the released packages instead. In order to compile the latest versions of FPC, first install a precompiled 2.

You can get a compiled version of FPC 2. Note: only do this if the instructions below do not work. You can also use fink. Create a directory, where you would like to put the sources. You don't need to be root to do this. Any normal user can do this. First create a directory for fpc.

This will create a directory called 'fpc', which can be later used in the IDE. Normally you uninstall an application on OS X simply by dragging it from the Applications folder to the trash. But because Lazarus and Free Pascal are. You can copy and save the commands below to file uninstallLaz. You can usually install newer versions of Lazarus and Free Pascal over older versions, but as with most software it's not a bad idea to clean out everything before you install a newer version.

  1. comment trouver ladresse ip de mon ordinateur mac.
  2. save as csv file on mac!
  3. windows get ip address from mac?
  4. internet filter for mac reviews.
  5. file format mac and pc?

This list of commands should also give you a sense of where the various pieces of Lazarus and Free Pascal are located. Note that this assumes you have version 2. If you have a different version, change the two relevant commands to specify. Note: Lazarus also creates a. You can leave this folder alone if you want the new version of Lazarus you're installing to use your old settings. OS X normally doesn't show files or folders whose names start with a dot. To see this folder and its contents, enter the following in a terminal window:.

You can not compile the IDE with the range check flag -Cr. On OS X The carbon interface has matured and is probably preferred over the gtk2 interface by most users of lazarus:. The carbon IDE looks somewhat nicer, although autosizing does not yet work correctly. Therefore, some dialogs look pretty bad until you enlarge them manually. Sometimes the blinking cursor vanishes after closing a file. Just switch to another page and back. The Lazarus interface to Android. Windows Programming Tips - Desktop Windows programming tips.
