好吧，我使用Ocamlyacc製作詞法分析器和解析器。我已經完成了我的研究，我認爲這與我的makefile沒有爲我的編譯器選擇正確的位版本或類似的東西有關？我不太瞭解makefile，這就是我問的原因。gcc ld：找不到架構x86_64的符號
我在另一臺電腦上運行我的程序，它沒有任何問題，所以它必須與我的機器有關。
這是一個MacBook Pro 64位。我正在使用Xcode 4.2.1。
這裏的生成文件：
SHELL = /bin/sh
C_C = gcc
CPP_C = g++
ifdef GPROF
C_CPP_FLAGS = -pg -O3
else
ifndef DEBUG
C_CPP_FLAGS = -O3
else
C_CPP_FLAGS = -g
endif
endif
C_LD = $(C_C)
CPP_LD = $(CPP_C)
C_YACC = bison
C_LEX = flex
AR = ar
RANLIB = ranlib
OCAML_C = ocamlc
OCAML_OPT_C = ocamlopt
ifdef GPROF
OCAML_C_FLAGS = -dtypes
OCAML_OPT_C_FLAGS = -dtypes
OCAML_LD = $(OCAML_C) -g
OCAML_OPT_LD = $(OCAML_OPT_C) -p
else
ifndef DEBUG
OCAML_C_FLAGS = -dtypes
OCAML_OPT_C_FLAGS = -dtypes
OCAML_LD = $(OCAML_C) -g
OCAML_OPT_LD = $(OCAML_OPT_C)
else
OCAML_C_FLAGS = -dtypes
OCAML_OPT_C_FLAGS = -dtypes
OCAML_LD = $(OCAML_C) -g
OCAML_OPT_LD = $(OCAML_OPT_C)
endif
endif
OCAML_MKTOP = ocamlmktop
OCAML_CP = ocamlcp
OCAML_DEP = ocamldep
OCAML_LEX = ocamllex
OCAML_YACC = ocamlyacc
OCAML_C_CPP_INC = -I $(shell $(OCAML_C) -v | tail -1 | sed -e \
's/^Standard library directory: //')
是我得到的錯誤是：
ld: symbol(s) not found for architecture x86_64
下面是完整的輸出：

預先感謝您！編輯： 我只使用Ocaml。沒有C++或C需要與它鏈接。我從來沒有試過用makefile運行我的ocaml代碼，但是我可以在這臺計算機上運行其他ocaml代碼。這是第一次失敗，但這是我第一次使用makefile。
而且相同的生成文件和代碼在其他機器上工作（儘管老機器），所以我認爲這與使用64位的這一個有關。
，我發現我已經給另一個生成文件看起來像這樣：

啊，我看到的i386所以這是一個32位編譯器。如何讓我的g ++/gcc編譯器以32位而不是64位運行？ – 2012-02-15 21:54:27
'cc -arch i386'適合我。 – 2012-02-15 22:01:44
我已經嘗試了「gcc -arch i386」和「gcc -arch amd64」。這兩個結果如下： 「ld：warning：忽略文件/usr/local/lib/ocaml/libcamlrun.a，該文件是爲歸檔而構建的，而不是被鏈接的體系結構（x86_64）」。 – 2012-02-16 04:54:47
