Build current FPC and Lazarus for Raspbian/zh CN

Raspbian Buster (基于 Debian 10 Buster)，在存储库中有开用FPC和Lazarus， but they suffer from the same "design decisions" that don't allow for a nice experience, namely the smooth IDE rebuilding capability based on source packages that is possible with FPC/Lazarus official .deb packages vs the crippled experience with the official Debian/Raspbian packages. One wishes there were official FPC/Lazarus packages for Raspbian as there are for Intel Debian/Ubuntu, which are also frequently updated; not being that the case (at least for now), this page shows the steps for building your own FPC, FPC-source and Lazarus packages for Raspbian. Example shows steps for Lazarus 2.0.6 which includes FPC 3.0.4, most recent at the time of writing. Adjust accordingly.
- Raspberry Pi 4 Model B, 4 GB (更少的内存将需要swap), with appropriate cooling (author uses aluminum case that doubles as heatsink) to avoid throttling due to excessive heat
- Latest Raspbian Buster fully updated
sudo apt install subversion
- 获取bootstrap FPC compiler. The latest compiler is compiled with the previous version of itself.
fpc-3.0.2.arm-linux目录。(NOTE: this folder must be on a linux FS [like Documents folder] as FAT doesn't allow the next step to work).
- 在这个目录中, as pi user, 运行
- At the four prompts, answer
Enter, n, n, n: this is, accept suggested directory
/home/pi/fpc-3.0.2, no Textmode IDE, no documentation, no demos. Ignore
tarwarnings. Note the additional files written to
.fppkg/config/default. When the build is done, to delete this temporary bootstrap compiler these files and the
/home/pi/fpc-3.0.2install directory need to be deleted.
- Temporarily add FPC install directory to PATH:
export PATH=$PATH:$HOME/fpc-3.0.2/bin. If you have to reboot for any reason before completing the FPC build, you have to do this step again.
- Test if all ok:
fpc abcd. This invokes the just installed compiler trying to compile a non-existent file (abcd). A multiline message will be shown including the compiler version.
- Non-step note: the following steps are mostly based on this
sudo apt install libgtk2.0-dev libgpm-dev libncurses-dev
svn co https://svn.freepascal.org/svn/fpc/tags/release_3_0_4 fpc, you have to be online for this and the next step to work.
svn co https://svn.freepascal.org/svn/lazarus/tags/lazarus_2_0_6 lazarus
create_fpc_deb.sh, look for line with the following content:
arm) ppcbin=arm; FPCArch=arm;;, (currently line 109). Copy and paste this line below itself, so it will appear twice. Edit this copy to read like this:
armhf) ppcbin=arm; FPCArch=arm;;. Now save the changes and exit.
./create_fpc_deb.sh fpc ~/pascal/fpc/. This will compile the latest compiler with the bootstrap compiler. It takes about 11 minutes. A
.debfile will be created:
fpc-laz_3.0.4-yymmdd_armhf.deb; the exact name will be shown at the end of the compilation. Rename the file with (NOTE: do not type the brackets): mv [file name shown at end of compilation]
- 卸载bootstrap FPC:
rm -rf ~/.fpc.cfg ~/.config/fppkg.cfg ~/.fppkg ~/fpc-3.0.2 ~/tmp. Check what you just did:
fpc abcdshould say command is not found.
- Install the just created FPC Debian package:
sudo dpkg -i ~/pascal/lazarus/tools/install/fpc-laz_3.0.4_armhf.deb. Check if it works:
fpc abcdshould show the newly installed FPC compiler.
./create_fpc_deb.sh fpc-src ~/pascal/fpc/. This builds the FPC source package in about 3 minutes:
fpc-src_3.0.4-yymmdd_armhf.deb. Rename with: mv
create_lazarus_deb.sh, look for line with the following content:
echo "$Arch is not supported.", (currently line 86). Copy the 3 lines above it and paste them just below themselves: at this time it is copy lines 83 to 85 and paste them between lines 85 and 86. In the just pasted lines (lines 86-88), replace
ppcarm. Look for the first
fijust below; copy and paste it below itself (copy line 91 below itself, so line 91 and 92 read the same). For you coders out there, you are adding another
ifto a nested
if, with its corresponding
./create_lazarus_deb.sh。这将构建Lazarus IDE Debian软件包
sudo dpkg -i fpc-src_3.0.4_armhf.deb lazarus-project_2.0.6-0_armhf.deb
rm -rf ~/pascal ~/tmp
You can now finally enjoy your fully working, fully up to date Lazarus. Find it in the Programming section of the Raspberry menu. A message titled "Error in EditorMacroScript" will be shown on first run; this also appears in the Raspbian Lazarus, reason still unknown to the original author of this page.现在尝试安装一个软件包，例如：
