Hello, I came across weird duplicate symbol errors while using functors and the -static flag in CHICKEN 5.
You can find the full repro here in case my explanation is not clear: https://github.com/antoine1fr/chicken-functor-static-error. Given: * a unit 'a', * a unit 'make-b' that defines a functor 'make-b' and uses 'a', * a unit 'b-foo' that creates the module 'b-foo' from 'make-b'. The following link command: $ csc -v -static -o test ./a.o ./make-b.o ./b-foo.o ./test.o generates the following call to the C compiler: 'clang' 'test.o' 'b-foo.o' 'make-b.o' 'a.o' 'a.o' -o 'test' -m64 -L/usr/local/Cellar/chicken/5.0.0/lib /usr/local/Cellar/chicken/5.0.0/lib/libchicken.a -lm The problem is that 'a.o' is issued twice to clang. This results in duplicate symbol errors. Here are the full build logs: $ make csc -J -static -o a.o -c a.scm csc -J -static -o make-b.o -c make-b.scm csc -J -static -o b-foo.o -c b-foo.scm csc -J -static -o test.o -c test.scm csc -v -static -o test ./a.o ./make-b.o ./b-foo.o ./test.o 'clang' 'test.o' 'b-foo.o' 'make-b.o' 'a.o' 'a.o' -o 'test' -m64 -L/usr/local/Cellar/chicken/5.0.0/lib /usr/local/Cellar/chicken/5.0.0/lib/libchicken.a -lm duplicate symbol _C_a_toplevel in: a.o ld: 1 duplicate symbol for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) Error: shell command terminated with non-zero exit status 256: 'clang' 'test.o' 'b-foo.o' 'make-b.o' 'a.o' 'a.o' -o 'test' -m64 -L/usr/local/Cellar/chicken/5.0.0/lib /usr/local/Cellar/chicken/5.0.0/lib/libchicken.a -lm make: *** [test] Error 1 Can someone tell me what I'm doing wrong?
