I have been
<br>writing an interface the math constants from math.h - I'm testing out
<br>methods of using "C inline". Only 2 of the functions compiled:
<br><br>
<br><br>
<br><br> Huge: REAL_64 is
<br><br> -- maximum value of a
<br>double.
<br><br> external
<br><br> "C inline use <math.h>"
<br><br> alias
<br><br> "return HUGE;"
<br><br> end
<br><br>
<br><br>
<br><br> Huge_val: REAL_64 is
<br><br> -- Positive infinity.
<br><br> external
<br><br> "C inline use <math.h>"
<br><br> alias
<br><br> "return HUGE_VAL;"
<br><br> end
<br><br>
<br><br>Here is one that did not compile:
<br><br>
<br><br>
<br><br> M_e: REAL_64 is
<br><br> -- Base of natural
<br>logarithms (e).
<br><br> external
<br><br> "C inline use <math.h>"
<br><br> alias
<br><br> "return M_E;"
<br><br>
<br><br>Here is the error message from the C compiler:
<br><br>
<br><br>c:\users\saunders\documents\eiffel 6.2 user
<br>files\projects\mandolin3\eifgens\mandolin3_project\w_code\c4\ma2007.c(47) :
<br>error C2065: 'M_E' : undeclared identifier
<br><br>NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio
<br>9.0\VC\Bin\amd64\cl.EXE"' : return code '0x2'
<br><br>Stop.
<br><br>
<br><br>All three functions appear to be written correctly. In my code I also
<br>included all of the other constants from math.h and they got similar errors
<br>from the C compiler, I just commented out all the others that failed and
<br>froze so I could keep this short. My apologies to Eric Bezault, who
<br>responded to the original message, because of the error.
<br><br>
<br><br>Does this suggest there is some kind of bug in EiffelStudio?
<br><br>
<br><br>Regards

I was
<br>working on a class to interface to the constants from math.h. Here are the
<br>two functions that compile correctly:
<br><br>
<br><br>
<br><br> Huge: REAL_64 is
<br><br> -- maximum value of a
<br>double.
<br><br> external
<br><br> "C inline use <math.h>"
<br><br> alias
<br><br> "return HUGE;"
<br><br> end
<br><br>
<br><br>
<br><br> Huge_val: REAL_64 is
<br><br> -- Positive infinity.
<br><br> external
<br><br> "C inline use <math.h>"
<br><br> alias
<br><br> "return HUGE_VAL;"
<br><br> end
<br><br>
<br><br>here is one that fails on C compilation:
<br><br>
<br><br> M_log2e: REAL_64 is
<br><br> -- Base-2 logarithm of e.
<br><br> external
<br><br> "C inline use <math.h>"
<br><br> alias
<br><br> "return M_LOG2E;"
<br><br> end
<br><br>
<br><br>Actually the rest fail to C compile as well but I'm trying to keep this
<br>short.
<br><br>Here's the message from the C compiler:
<br><br>
<br><br>c:\users\saunders\documents\eiffel 6.2 user
<br>files\projects\mandolin3\eifgens\mandolin3_project\w_code\c4\ma2007.c(47) :

<br>9.0\VC\Bin\amd64\cl.EXE"' : return code '0x2'
<br><br>Stop.
<br><br>
<br><br>Does it appear that I should make a bug report for this?
<br><br>

I should have seen the
<br>obvious code error but sometimes the obvious is something you just can't
<br>seem to see. I altered the code to this:
<br><br>
<br><br>
<br><br> quot (a_item: POINTER): INTEGER
<br><br> external
<br><br> "C inline use <stdlib.h>"
<br><br> alias
<br><br> "[
<br><br> {
<br><br> struct
<br>div_t* itm = $a_item;
<br><br> return
<br>(int)(itm->quot);
<br><br> }
<br><br> ]"
<br><br> end
<br><br>
<br><br> set_quot (a_item: POINTER; v: INTEGER)
<br><br> external
<br><br> "C inline use <stdlib.h>"
<br><br> alias
<br><br> "[
<br><br> {
<br><br> struct
<br>div_t* itm = $a_item;
<br><br>
<br>(int)(itm->quot) = $v;
<br><br> }
<br><br> ]"
<br><br> end
<br><br>
<br><br>I now get the error:
<br><br>
<br><br>c:\users\saunders\documents\eiffel 6.2 user
<br>files\projects\mandolin3\eifgens\mandolin3_project\w_code\c4\di2005.c(43) :

<br><br>Stop.
<br><br>
<br><br>div_t is declared in stdlib.h so I don't see why this should appear to be
<br>undefined to the C compiler. I would also like to ask Eric why the need for
<br>the brackets around (itm->quot)? Here is the declaration of div_t from my
<br>version of stdlib.h:
<br><br>
<br><br>
<br><br>typedef struct _div_t {

<br><br> int rem;

I'm not at all sure that I
<br>should be using this approach and would like some advice on weather I should
<br>use this approach. I am also getting an error when C compiling and can't
<br>see the source of the error (my C is limited). Here is the code I wrote:
<br><br>
<br><br>
<br><br> quot (a_item: POINTER): INTEGER
<br><br> external
<br><br> "C inline use <stdlib.h>"
<br><br> alias
<br><br> "[
<br><br> {
<br><br> struct
<br>div_t* itm = $a_item;
<br><br> return
<br>(int)a_item->quot;
<br><br> }
<br><br> ]"
<br><br> end
<br><br>
<br><br> set_quot (a_item: POINTER; v: INTEGER)
<br><br> external
<br><br> "C inline use <stdlib.h>"
<br><br> alias
<br><br> "[
<br><br> {
<br><br> struct
<br>div_t* itm = $a_item;
<br><br>
<br>(int)a_item->quot = $v;
<br><br> }
<br><br> ]"
<br><br> end
<br><br>
<br><br>The compiler error is:
<br><br>
<br><br>c:\users\saunders\documents\eiffel 6.2 user
<br>files\projects\mandolin3\eifgens\mandolin3_project\w_code\c4\di2005.c(43) :

<br>would like to hand craft their own COM C++ 'lite' interface to
<br>something which can be then be wrapped in Eiffel fairly easily.
<br><br>The purpose of the code is to read and write Windows link files (aka
<br>Shortcuts).
<br><br>The last_operation_succeeded function is intended for calling from an
<br>Eiffel check or ensure contract. The only other calls you need to use
<br>this code is a global initialize/uninitialize call which you can put
<br>into some once procedures shared globally. The uninitialize procedure
<br>can be used to implement a dispose.
<br><br>feature {NONE} -- C externals
<br><br> c_com_initialize (v_reserved: POINTER): INTEGER is
<br> -- WINOLEAPI CoInitialize(IN LPVOID pvReserved);
<br> -- Call this with Default_pointer for CoInitialize (NULL);
<br><br> external
<br> "C (IN LPVOID): EIF_INTEGER | <objbase.h>"
<br> alias
<br> "CoInitialize"
<br> end
<br>
<br> c_com_uninitialize is
<br> -- void CoUninitialize ();
<br> external
<br> "C | <objbase.h>"
<br> alias
<br> "CoUninitialize"
<br> end
<br><br>Sorry I have not included the Eiffel wrapper which is part of a basic
<br>toolkit for writing Windows installers. At some point I will be
<br>releasing this toolkit as part of a general set of assorted libraries.
