Building cygwin.dll

Building cygwin.dll

[Bill Petheram]

I am trying to build a dll for debugging.

I down loaded cygwin-1.3.2-1.src.tar.gz untar it and do a ./configure,
fairly standard isn't it?

but I keep getting errors in newlib such as

.:Can't open ./.././install-sh: No such file or directory.

It seems to look in i686-pc-cygwin.

What am I doing wrong?

thanks

bill

not reading FAQ, apparently. see

for details about rebuilding dll.

No excuse, but I didn't think I was rebuilding the tools.

From the FAQ:

	Note: You must build in a directory outside the source tree.

thanks

Classic include_next problem. As a quick workaround, edit the file
/usr/obj/cdk/gcc/gcc/include/limits.h, and remove the beginning and
ending extra stuff to include a system specific limits file if it
exists.

Basically, delete the initial lines until your first line is the
following:
  #ifndef _LIMITS_H__

now delete backwards from the end until your last line is:
  #endif /* _LIMITS_H__ */

The #include_next is expecting to find another limits.h file based upon 
the include paths.  The documentation for this can be found in the 
cpp.info file.

building cygwin.dll

[Larry Hall]

Perhaps someone can help me.

I'm trying to build the cygwin DLL.  I'm using the source with the original
b18 distribution plus the source for winsup and newlib from Sergey's 
coolview-src_tar.gz, circa 10/30.  I'm building on NT 4.0 + sp3.  I have 
substituted the original b18 signal.h for the one in Sergey's newlib 
directory in addition to removing #ifdef OLDWAY statements from code in 
this directory.  The configure went fine.  The source is in /usr/src/cdk 
and the objects in /usr/obj/cdk.  All mounts are binary.  I start the 
compile with 

make all-target-winsup

in the /usr/obj/cdk directory.  This proceeds uneventfully until it reaches
the /usr/obj/cdk/gcc directory.  When it goes to compile 
/usr/src/cdk/newlib/libm/math/s_ilogb.c, it complains:

/usr/obj/cdk/gcc/xgcc -B/usr/obj/cdk/gcc/ -idirafter 
/usr/obj/cdk/./newlib/targ-include -idirafter 
/usr/src/cdk/newlib/libc/include -nostdinc -O2  -O2 -DHAVE_OPENDIR 
-DHAVE_RENAME -DSIGNAL_PROVIDED -fno-builtin 
-I/usr/obj/cdk/newlib/./targ-include -I/usr/src/cdk/newlib/./libc/include 
-c /usr/src/cdk/newlib/libm/math/s_ilogb.c
In file included from /usr/obj/cdk/gcc/include/syslimits.h:7,
                 from /usr/obj/cdk/gcc/include/limits.h:11,
                 from /usr/src/cdk/newlib/libm/math/s_ilogb.c:62:
/usr/obj/cdk/gcc/include/limits.h:116: limits.h: No such file or directory
make[3]: *** [s_ilogb.o] Error 1
make[2]: *** [math/lib.a] Error 1
make[1]: *** [libm/libm.a] Error 2
make: *** [all-target-newlib] Error 2

I've attached the limits.h and syslimits.h file the above error references.
My CPLUS_INCLUDE_PATH and C_INCLUDE_PATH read as follows:

CPLUS_INCLUDE_PATH=/usr/include:/usr/include/g++
C_INCLUDE_PATH=/usr/include

These paths are valid.  Obviously, a limits.h file exists since its the
one complaining that it cannot find limits.h.  The line that generates
the complaint reads:

#include_next <limits.h>        /* recurse down to the real one */

I have not been able to find anything in man pages that tell me what 
#include_next should do.  Can anyone tell me why I get this complaint and
what I might try to rectify it?

TIA,
