EXIT_SUCCESS and NO_RETURN in /lib-src

EXIT_SUCCESS and NO_RETURN in /lib-src

[William Xue]

I build emacs-unicode-2 in winxp with MinGW, and it failed in /lib-src.

It says that the compile could not find the definition of EXIT_* and  
NO_RETURN in hexl.c and ebrowser.c and sorted-doc.c.

In hexl.c, I added
#ifdef HAVE_STDLIB_H
#include <stdlib.h>
#endif

in ebrowser.c, I added
#define NO_RETURN

and in sorted-doc.c, I added
#else
#include <stdlib.h>
#endif
in #ifndef HAVE_STDLIB_H

Maybe this is not the right way to build emacs under windows, but it  
works. This is not the first time that I encountered these errors.
I think that somebody should have a check about them.

Another error is about the movemail.c:

Can you explain why this problem doesn't happen on HEAD?  AFAICS, the
MinGW build of Emacs pulls in stdlib.h from src/s/ms-w32.h, which is
included by config.h.  Can you see why this doesn't happen for you?

Shouldn't be needed, either: NO_RETURN is defined in config.h.

Same here.  It sounds like your compilation doesn't include config.h
for some reason, or maybe config.h is empty.  Please try to see why.

Probably for the same reason: the Windows build is not supposed to
compile the code that uses the `link' function.

NO_RETURN is defined in config.h, like this:

474 #ifndef NO_RETURN
475 #if defined __GNUC__ && (__GNUC__ > 2 || (__GNUC__ == 2 &&  
__GNUC_MINOR >= 5))
476 #define NO_RETURN       __attribute__ ((__noreturn__))
477 #else
478 #define NO_RETURN       /* nothing */
479 #endif
480 #endif

maybe is skipped by line 475.

IMHO, config.h was included. But could you teld how to confirm it?

??? You did say you use MinGW, didn't you?  If so, your compiler is
GCC, which defines __GNUC__, and I cannot believe your GCC version is
less than 2.5.  What does "gcc --version" say?

> IMHO, config.h was included.  But could you teld how to confirm it?

Add to it an #error directive, and see if GCC emits the error
message.  Add that directive at the beginning, then at the end, and
see if the file is used in its entirety.

I think when you find and solve the other problems, this one will be
solved with them.

I have found something in makefile:

when run configure.bat in nt folder, I have specified '--cflags -I./inc'.
After I removed the -I../nt/inc in the makefile in lib-src folder, the  
build is OK.

It seems that only one -I flag allowed in this situation.
I specified the include path because I put all the graphic's header  
files(gif, bmp, jpg, tiff, etc) in there.

I did not know many about the flags in MinGW and GCC. Is there something  
wrong or it is the limitation of the compiler?

FWIW, I build the emacs-unicode-2 branch on Windows XP with MinGW (gcc
(GCC) 3.4.5 (mingw special) according to -v), passing -I to
configure.bat:

 cmd /c configure.bat --with-gcc --no-cygwin --cflags -IC:/emacs/build/include

and it works just fine.

Finally, I find the reason of the issue. In my '../nt/inc' folder, there  
is another 'config.h' which is for 'libxpm', I think.
So, after I specified the '--cflags -I./inc' as a parameter of  
configure.bat, the errors is running.

IMHO, This is a potential bug, anyway, I should include that 'config.h' if  
I want to build emacs with graphics supported.

I don't know what XPM library are you using. The one at GnuWin32 does
not have any config.h; you only need xpm4.dll in the path and
X11/xpm.h in your include dir.

Maybe you are right, I only simplely copied all the header files in libxpm  
in to that folder.
Not include a 'config.h' header file in a released lib, maybe this is the  
rule.

Well, if you drop into the compiler's include path all kinds of
unneeded files is no wonder that you accidentally find a conflict :)

I'm building Emacs on Windows with full image support (all image types
except Postscript, which is unsupported on Windows), and my include
dir contains just this:

gif_lib.h
jconfig.h
jerror.h
jmorecfg.h
jpeglib.h
png.h
pngconf.h
simx.h
tiff.h
tiffconf.h
tiffio.h
tiffvers.h
zconf.h
zlib.h
X11\xpm.h

As you have found out, the problem was an extra config.h in ../nt/inc.

In general, it is advisable to put the header files for the graphics
libraries in the same directory where the compiler header files are.
