proc预编译通过生成相应的c文件，然后通过c编译器编译提示D:\workspace\test\main.c|327|undefined reference to `sqlcxt'|
我初步判断不是因为库函数没有引用，因为我把sqlcxt函数中的参数改变的时候提示参数数目不对，所以是有这个函数的，我怀疑是我写的程序有问题现在程序贴出来。系统用的win764位，oracle11g64位，客户端什么的完全安装，编译器用的codeblock

NAME
SQLCA : SQL Communications Area.
FUNCTION
Contains no code. Oracle fills in the SQLCA with status info
during the execution of a SQL stmt.
NOTES
*** This file is SOSD. Porters must change the data types ***
*** appropriately on their platform. See notes/pcport.doc ***
*** for more information. ***
If the symbol SQLCA_STORAGE_CLASS is defined, then the SQLCA
will be defined to have this storage class. For example:
#define SQLCA_STORAGE_CLASS extern
will define the SQLCA as an extern.
If the symbol SQLCA_INIT is defined, then the SQLCA will be
statically initialized. Although this is not necessary in order
to use the SQLCA, it is a good pgming practice not to have
unitialized variables. However, some C compilers/OS's don't
allow automatic variables to be init'd in this manner. Therefore,
if you are INCLUDE'ing the SQLCA in a place where it would be
an automatic AND your C compiler/OS doesn't allow this style
of initialization, then SQLCA_INIT should be left undefined --
all others can define SQLCA_INIT if they wish.
If the symbol SQLCA_NONE is defined, then the SQLCA variable will
not be defined at all. The symbol SQLCA_NONE should not be defined
in source modules that have embedded SQL. However, source modules
that have no embedded SQL, but need to manipulate a sqlca struct
passed in as a parameter, can set the SQLCA_NONE symbol to avoid
creation of an extraneous sqlca variable.
MODIFIED
lvbcheng 07/31/98 - long to int
jbasu 12/12/94 - Bug 217878: note this is an SOSD file
losborne 08/11/92 - No sqlca var if SQLCA_NONE macro set
Clare 12/06/84 - Ch SQLCA to not be an extern.
Clare 10/21/85 - Add initialization.
Bradbury 01/05/86 - Only initialize when SQLCA_INIT set
Clare 06/12/86 - Add SQLCA_STORAGE_CLASS option.
