Please see the Lazarus For Delphi Users guide for a description of some of the functional differences.
and in someĪreas, FPC is enhanced and can be more demanding about correct syntax. ThereĪre a number of library call and convention differences. Have aspects in common with Delphi and Kylix, they are not clones. While Lazarus and the Free Pascal Compiler This page is about how to port or convert existing Delphi or Kylix code to work with the Free PascalĬompiler and Lazarus IDE. What else is already on Gentoo64, Python, Perl, PHP? How many can be used for baremetal on Pi's? I cannot say I am not learning about compilersĭo C compilers make the smallest helloworld exe files?Ĭ, C++, gnu and clang, Rust, Go, Pony, Pascal can now be tested. The Lazarus IDE is built from source and needs a working fpc install.Ī Gentoo ebuild script to install the binary from the snapshot file may be easier to learn than the usual install from source.īut as I understand ebuild it is so things are built from source. Lazarus is the normal IDE for Free Pascal but as shown Geany can be used for simple stuff. The snapshot 3.3.1 works fine if just unzipped to a folder.Ĭan it be used to make an Aarch64 3.0.4 build version, which is then used to make the 3.3.1 version? However there is no aarch64 3.0.4 version, catch 22. fpc.cfg file with all the paths etc sorted out.Įxisting installs like fpcup, fpcupdeluze will build fpc/lazarus from source grabbed from the net.īuilding from source requires a build compiler version with 3.0.4 being the latest version? Most install methods will automatically generate a. Hello is a 1MB+ executable file as it contains the runtime + debug as well. Path issues means cut and pasting missing files to where they can be found. Normal installs to Windows and x86 Linux is well documented,but those install scripts work anyway. Latest 3.3.1 Aarch64 fpc is compiling but manual installation needs more manual reading. And once FPC is available, we can look at Lazarus. So, if you could point me to either or both of the above, I'd be happy to write the ebuild for FPC. Where (3) is the binary package used during bootstrapping (the precompiled/binary FPC compiler therein is used to compile the FPC sources, and the resulting FPC compiler is then used to compile the FPC sources again).Īccordingly, to build on aarch64-linux rather than x86_64, I'd either need an equivalent binary package to (3) for aarch64-linux (which I can't see on sourceforge at a quick glance, although it's entirely possible I've missed it!), or some detailed cross-compilation instructions from x86_64-linux to aarch64-linux (as I don't use FPC day-to-day). Linux/3.0.4/fpc-3.0.4.x86_64-linux.tar/download (for bootstrapping on 64-bit linux PCs only).Source/3.0.4/fpcbuild-3.0.4.tar.gz/download (OK for all arches).So on a 64-bit Linux PC, for example, it would download (from prefix ): To be more specific: currently, the 3.0.4 ebuild downloads the generic FPC build and source packages from sourceforge, and then an arch-specific binary package, also from sourceforge. To write a tweaked one that will work, I'd need an aarch64-linux binary FPC package for the bootstrapping phase of the build (as modern FPC seems to need FPC to build it, essentially, much as rust needs rust to build), or detailed cross-compile instructions. The current main-tree FPC ebuild on Gentoo doesn't support aarch64/arm64 at the moment. So, I had a quick look at FPC yesterday, since you'd mentioned it earlier.
