Hello, I was trying to compile Racket Textual from source in a Webfaction's shared host machine. It's running CentOS 5.6.
After downloading and extracting the tarball, cd racket-textual-5.1.2/src/; mkdir build; cd build; ../configure; make: --------------------------------------------------- [...lots of things...] ar: creating ../libracket3m.a a - salloc.o a - bignum.o [...] a - validate.o a - vector.o a - foreign.o a - ../src/gmp.o a - ../src/unwind.o a - ../../foreign/libffi/src/closures.o a - ../../foreign/libffi/src/debug.o a - ../../foreign/libffi/src/java_raw_api.o a - ../../foreign/libffi/src/prep_cif.o a - ../../foreign/libffi/src/raw_api.o a - ../../foreign/libffi/src/types.o a - ../../foreign/libffi/src/x86/ffi.o a - ../../foreign/libffi/src/x86/sysv.o a - gc2.o ranlib ../libracket3m.a cd ..; gcc -o racket3m gc2/main.o libracket3m.a -pthread -ldl -lm -ldl -lm -rdynamic libracket3m.a(symbol.o): In function `mzrt_cas': /home/rodolfo/racket-textual-5.1.2/src/build/racket/gc2/../../../racket/gc2/../src/mzrt.h:132: undefined reference to `__sync_bool_compare_and_swap_4' collect2: ld returned 1 exit status make[4]: *** [../racket3m] Error 1 make[4]: Leaving directory `/home/rodolfo/racket-textual-5.1.2/src/build/racket/gc2' make[3]: *** [all] Error 2 make[3]: Leaving directory `/home/rodolfo/racket-textual-5.1.2/src/build/racket/gc2' make[2]: *** [3m] Error 2 make[2]: Leaving directory `/home/rodolfo/racket-textual-5.1.2/src/build/racket' make[1]: *** [3m] Error 2 make[1]: Leaving directory `/home/rodolfo/racket-textual-5.1.2/src/build' make: *** [all] Error 2 --------------------------------------------------- I tried three times and consistently got the same error. Then I decided to try 5.1.1, and I was able to compile with no errors. Could it be the case that something is wrong with racket-textual-5.1.2-src-unix.tgz? (the "/mzrt.h:132: undefined reference to `__sync_bool_compare_and_swap_4'" part) []'s Rodolfo Carvalho
