Re: wstring support in GCC 4.1.2 in Cygwin 1.5.25-11
Ya I am trying MinGW now.
But since it is like building on the windows platform, we need to get round
with
concepts which differ on the posix and the windows system. Currently I am
dealing with the Signals, one such problem. In in my linux based code we
have used
the sigaction() concept which is not supported in MinGW.
Now I am bit worried to estimate the time for the complete activity as I
will
have to make modifications in the code to make porting successful.

No, it's what you'd expect if you try and dup a handle that's already been closed - an indication that the child exited prematurely. This is one of those semi-generic fork failures that could be BLODA, but another possibility is that because this is a non-cygwin app being launched from cygwin, it might be pulling in a dll that causes a rebase conflict. Following the rebaseall procedure described in the "Usage:" section of /usr/share/doc/Cygwin/rebase-2.4.3.README might help as is, or it might be necessary to find a list of the dlls being pulled in by the borland compiler and rebase them too by adding a -T option pointing to a file that lists the (cygwin-style posix) paths to the BC45 dlls. cheers, DaveK -- Can't think of a witty .sigline today -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

The problem is that the request can't be executed because we have no mapping from uid 4 to a Windows SID. OTOH, the underlying Solaris function acl() does not define any error code for a non-existant user because it's not an error on Solaris. What error code do you want? EINVAL?

Right. That's the thing - this is a different error condition, one
that could not possibly arise on Solaris (since there is only one
concept of user there). The question is, what should the error code
be for this new condition that can only arise on Cygwin? Since it's
an invalid user identity for the requested operation, EINVAL seems
appropriate; it's just not what the man page says EINVAL means in this
context.
The only other standard error code that leaps out at me as possibly
appropriate is EPERM ("Operation not permitted").
Sadly, the "no such thing exists" errors are all quite specific as to
the thing in question: ENOENT for files, ESRCH for processes, ENXIO
for devices, etc.

Re: wstring support in GCC 4.1.2 (OS independent)

Compiling with -mno-cygwin means that you can't use ANY cygwin headers. You won't be able to create an executable which works this way. When Dave said "...cygwin doesn't supply or support " he wasn't kidding. It isn't supplied and copying it from a random source and randomly making changes is not going to work. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
Re: cscope on cygwin
Hi Eva, Sorry for the delay in replying - I just checked my cscope mail. You can do what you want, but you are falling in to the trap of .cmd file extensions. When you set the EDITOR variable to a .cmd file, it will be run as a windows script, not a bash script. Your use of "&" only works in bash scripts, not windows scripts. I created a script called "cs_edit" and did: shift /c/windows/notepad.exe $@ & Let me explain what this does.When I run mlcscope and pick a line, the arguments given to $EDITOR are "+2 filename" For some reason which I am not sure of right now, +2 is the first argument. That isn't right and I'll look at that separately, but for now the "shift" causes all the arguments to shift down one place and it drops the first arg so the arguments become just the filename, Then the $@ puts the argument list on the command line as you expected. I think the reason you tried %2 is to avoid that first argument right? As you deduced, the '&' runs the command in the background. Make sure that cs_edit is in your path and is executable (chmod 755 cs_edit), and you should be up and running. Let me know if you have any other problems. Cheers Dave Barladeanu Eva-BEB047 wrote: Hello, I am a newcomer to cygwin. I installed "mlcscope-14.1.8-2" on an XP service pack 2 machine. I built the cscope.out data base and I can run searches on the data base.

Please get your terms straight. glib is something MUCH different than glibc. glib is ported to cygwin, glibc is not. glib is a graphics library, glibc is an implementation of libc. Cygwin uses newlib as its implementation of libc. And that's why cygwin doesn't support wstring - because newlib does not have very complete wide character support.

They serve totally different purposes -- Cygwin is a user-mode library. If you want to make a comparison, compare Cygwin to glibc as they are both libcs. And again, the compiler suite cannot implement wstring without underlying libc wide character IO support which does not exist in newlib and therefore does not exist in Cygwin. Remember that gcc is divorced from the target libc because a libc is way too OS-dependent. gcc relies on the platform to implement its own libc, and everything gcc implements builds on top of an existing libc. If the libc doesn't have the necessary support there's nothing that libstdc++ can do about it but disable wstring.
