Hi Peter, and thanks for the help.
I've modified it as per your instructions, but when I run the resultant exe, but now I'm getting:
I tried adding -static when compiling the eggs, but that didn't help.
I've included a fresh zip of the sources, including a logfile showing the commands I'm issuing. Can you help further, please?

Perhaps I should not be doing that.I had several more problems, with the -uses flags being generated without a space before it, and setup-helper and blob-utils not compiling. After "fixing" that by hacking about a bit, I think I managed to make it work.However, when I run the resultant executable, I get an error about a missing intarweb extension. Which is strange, because if you look carefully at the command line above, you can see I'm both linking with its object file and referencing it with a uses declaration. What am I doing wrong, please?The problem is that you're requiring the extensions with -uses, but the code for http-client.scm still contains (use intarweb), which tries to load it at runtime. You're missing -uses declarations when compiling the eggs: you need to declare for each egg which eggs it uses, to avoid loading them dynamically. For example, if you refer to Evan's tutorial at http://www.foldling.org/scheme.html#compiling-statically-linked-chicken-scheme-programs-with-extensions you'll notice that he's compiling uri-generic, which depends on matchable and defstruct, as follows: csc -unit uri-generic -uses matchable,defstruct -cJ uri-generic/uri-generic.scm -o uri-generic.o The -uses declarations are not being emitted by your program when you compile the extensions.Incidentally, is there any way to instruct csc to use musl instead of libc? I'm told that this would eliminate any dependency on a specific version of libc on the target machine. I gather the musl project is a bit lacking in header files, however.I think you can do that by passing "-cc musl-gcc". Hope this helps! Cheers, Peter
