megahertz/fpc-trunk repository overview

⁠fpc-trunk

Free Pascal Compiler built weekly from trunk repository using alpine linux image⁠.

This image is built from trunk repository which contains all fixes and improvements since the last official release, so please try it if you have any problems. Of course, it may also contain new bugs.

If you need the latest stable FPC image instead of dev build, try the frolvlad's image⁠.

⁠Usage

1. Create a program, for example:

   { app.pas }
   program app;
   
   begin
     WriteLn('Hi from docker');
   end.
   
   

   Copy

2. Create a Dockerfile

   # Dockerfile
   FROM megahertz/fpc-trunk:3.1.1-39472
   
   COPY app.pas /src/my-program/app.pas
   RUN fpc /src/my-program/app.pas
   CMD /src/my-program/app
   
   

   Copy

3. Build the image and run

   docker build . -t app
   docker run app
   

   Copy

⁠Troubleshooting

⁠My app can't be run on another alpine image

In most cases, the app can't find ld-linux-x86-64.so.2. There are two ways to fix that:

• Add to your Dockerfile for the target image:

  RUN ln -s /lib /lib64 && \
      ln -s /lib/ld-musl-x86_64.so.1 /lib/ld-linux-x86-64.so.2
  

  Copy

• Compile your app with the following FPC flag:

  -FL/lib/libc.musl-x86_64.so.1
