Hi,

For compiling ROOT itself (in cygwin) you should just do
    export ROOTBUILD=debug
or
    setenv ROOTBUILD debug
depending of your shell (former is bash, later is tcsh).

I tried your modification in $ROOTSYS/test/Makefile and I have had NO
problem.
This more likely to be an environment setup problem and/or a broken
compilation.

Cheers,
Philippe

Dear Rooters and specialists of Cygwin with win32,

I work under Windows XP, VC++.NET, Cygwin with win32 (not win32gcc) and ROOT
3.05.05

I have tried to compile and link in debug mode under Cygwin . i.e, I have
replaced in the Makefile

CXXOPT           = -O2                by        CXXOPT           = -Z7
and
LDOPT             = -opt:ref           by        LDOPT             = -debug

The result is that the link fails with the message:

LINK : fatal error LNK2023: bad dll or entry point 'msobj10.dll'
make: *** [smuster.exe] Error 231


This happens on all programs, however short they are. This happens for
instance for the programs in $ROOTSYS/test.

The reason why I have tried this is that I wrongly believed that gdb would
work with the VC++ compiler. Axel Naumann told me it does not. So that in my
configuration, the only way to debug my programs remains VC++.NET and a
compilation under Cygwin in debug mode is not useful. I quote this just in
case it matters for somebody.
