I was having a problem with mkcramfs on cygwin creating symbolic links
for the compressed linux filesystem.
mkcramfs uses malloc to allocate a buffer that it sends to the readlink function in
cygwin path.cc
That function uses memcpy to do a copy of the link into a buffer.
Neither mkcramfs or rea
lstat returns an incorrect symbolic link size, with size 11 bytes too large.
This causes mkcramfs to fail.
CYGWIN variable is set to nowinsymlinks. Set to winsymlinks, the size is about 80
bytes too large.
This is for a cygwin snapshot from September.
This program generates the error for me. Creat
Hi,
I am attempting to build cygwin from source.
The make fails in i686-pc-cygwin/winsup/cygwin, error is

Before this point, the following messages were also emitted.

Hi.
I would like to use this function down to 10 milliseconds accuracy if possible.
However upon looking at winsup/cygwin/thread.cc,
it uses the function "ftime" and the millisecond field is ignored.
All the examples in the winsup testsuite also generally check to 5 seconds only.
Is there any in

Referring to the faq question "how do i rebuild the tools on my NT box"
the instructions are to "install everything", after the "make install" and
"make check" steps.
I understand the dll swapping trickery, but exactly what directories are to be
copied where with the "install everything" step?

In answer to my own query I copied from /install/* into /usr,
where the install directory hierarchy appeared to be rooted.

Hi,
I have a noticed a difference in execution between cygwin and linux for pthreads and
atexit. If exit is called by a thread, then functions lodged with atexit by the main
thread do not get invoked on cygwin, but do get invoked on linux. Because I am unsure
if this difference has been noted

Hi,
This was causing my build of gcc to fail.
File winsup/cygwin/mmap.cc version 1.86 (and earlier) function munmap
when unmapping a 64K record, passes the wrong parameters to fhandler_base::munmap,
passing the function parameter address/length instead of a block local version.
This patch exp
This test program highlights the recent munmap problem addressed by Corinna.
It works with the updated mmap, and with linux, fails on cygwin with the prior mmap.
/**
* mmap test.
* mmaps two chunks of adjacent memory, then munmaps one and a half,
* then sees if the remainder is still useable.

I said this test program works with both my own and corinna's fix, but in fact I have
only
actually tested it with corinna's fix, since I discarded my own.

Firstly, apologies for repeated postings to the gmane cygwin newsgroup, I thought they
were bounced.
If I profile my multi-threaded application, it appears that only the main thread is
profiled.
On linux, it is possible to save and set the virtual timer upon creation of each
thread, and thereb
Sorry for the delay, or the repeat information, my original reply is lost.
