Hello everyone,

I am just getting started using gsc to compile files, and I'm wondering how to go about debugging some error messages I'm seeing.

This is what I am doing:

== inside misha-sdl.scm == (println "hello world")

== inside terminal == gsc -link misha-sdl gcc misha-sdl.c misha-sdl_.c -I/Library/Gambit-C/v4.6.2/include -L/Library/Gambit-C/v4.6.2/lib -lgambc

== error message == ld: warning: ignoring file /Library/Gambit-C/v4.6.2/lib/libgambc.a, file was built for archive which is not the architecture being linked (x86_64) Undefined symbols for architecture x86_64: "____gstate", referenced from: ____H__20_misha_2d_sdl in cci2oaPA.o "____G_println", referenced from: ____H__20_misha_2d_sdl in cci2oaPA.o "_____20___gambc", referenced from: ____linker_tbl in ccR9LONi.o "____main_char", referenced from: _main in ccR9LONi.o

The notice about skipping libgambc.a is especially worrying.

However, using the command: gsc -o hello -exe misha-sdl.scm works perfectly. Is there any way to query to see what flags gsc is passing to gcc?

You can use the -verbose option to gsc :

gsc -verbose -o hello -exe misha-sdl.scm
