Re: [CM] S7 questions and libc issue

For tcc, I think you need the -rdynamic and -DWITH_C_LOADER flags: /home/bil/snd-22/ tcc -o s7 s7.c -I. -lm -DWITH_MAIN -ldl -rdynamic -DWITH_C_LOADER /home/bil/snd-22/ s7 s7: 13-May-2022 load /home/bil/snd-22/libc_s7.so failed: /home/bil/snd-22/libc_s7.so: cannot open shared object file: No s

Re: [CM] S7 questions and libc issue

;unbound variable (symbol "\x7f;ELF\x02;\x01;\x01;") This happens if you try to dynamically load an object file but don't have the dynamic loading functions -- when you build it without libdl (WITH_C_LOADER=0 probably). It treats libc_s7.so as a scheme (text) file. r7rs.scm needs the libc stuf

Re: [CM] S7 questions and libc issue

For gcc, use gcc -o s7 s7.c -I. -lm -DWITH_MAIN -DWITH_C_LOADER=0 -pthread -static libc_s7.so gives FFI bindings for a large portion of libc. repl.scm needs it to get raw terminal handlers. The WITH_C_LOADER switch is what you needed, I think. ___ C

Are setters portable? Probably not -- I don't know of any other scheme that has them. ___ Cmdist mailing list Cmdist@ccrma.stanford.edu https://cm-mail.stanford.edu/mailman/listinfo/cmdist

Re: [CM] S7 questions and libc issue

By support for types, are you referring to srfi-9 or srfi-99? That stuff is trivial; I'd use lets + methods in s7, but r7rs.scm also has an implementation using vectors. I thought you were referring to typed variables like saying "int i" in C. You'd use a setter for that in s7. __

Re: [CM] S7 questions and libc issue

That's an interesting project! To answer some of your questions: I think tcc can build s7 statically in linux. Here's an example in Ubuntu: tcc -o s7 s7.c -I. -lm -DWITH_MAIN s7 s7: 9-May-2022 (+ 1 2) 3 The -DWITH_MAIN switch includes a minimal repl, so you don't need repl.c or libc_s7.so.
