Subject: bootstrapping winsup-src-19990917
Date: Mon, 20 Sep 1999 18:27:18 +1000
X-Priority: 3
X-Mailer: Internet Mail Service (5.0.1458.49)

Periodically I build a complete system starting from scratch.

(BTW, does anyone know how to delete a registry key from a batch file?
Currently I have to manually zap the mount table.)



Attempt 1.
Building cygwin-src-19990913.tar.gz and winsup-src-19990917.tar.gz using

cygwin b20.1
"Jan 15" cygwin1.dll

I get the following error:
/build/src/cygwin/winsup/utils/cygcheck.cc: In function `void
dump_sysinfo()':
/build/src/cygwin/winsup/utils/cygcheck.cc:707: parse error before `)'
/build/src/cygwin/winsup/utils/cygcheck.cc:707: parse error before `,'

Is this a gcc 2.91 compiler error?

You can work around this by removing the typecast on the return from
GetProcAddress like this:

Attempt 2.
Building cygwin-src-19990913.tar.gz and winsup-src-19990917.tar.gz using

cygwin b20.1
"Jan 15" cygwin1.dll
gcc-2.95-cygb20.tar.gz
gcc-2.95-dev-ss.tar.gz

(note that cygcheck.cc compiles ok with gcc 2.95)
This gives the strace.exe _impure_ptr link error Corrinna reported in
http://sourceware.cygnus.com/ml/cygwin-developers/1999-08/msg00012.html.
As Mumit then suggested, this can be fixed by using libgcc.a from his
gcc-2.95-mingw-extra.tar.gz
I extracted this into /usr/local/mingw (as per Mumit's
mno-cygwin-howto.txt), then applied the following patch:

Everything then builds ok.

Has this issue been fully resolved?
I couldn't find any follow-ups other than the work-around suggested by
Mumit.
The problem with this patch is that it depends on where you put the
mingw stuff.
(I don't normally use mingw so I may have missed something obvious.)


Attempt 3.
Building cygwin-src-19990913.tar.gz and winsup-src-19990917.tar.gz using

cygwin b20.1
gcc-2.95-cygb20.tar.gz
gcc-2.95-dev-ss.tar.gz
gcc-2.95-mingw-extra.tar.gz in /usr/local/mingw
cygwin1.dll, libraries, etc built in Attempt 2 above.
This gives the same link error as Attempt 2 - the same patch fixes it.


Hopefully this post might save someone else some time.
