Re: [cdt-dev] CDT problems after upgrading to Cygwin 1.7
|
Thanks, Nils. That is brutal. It also highlights why CDT and Cygwin have such a hard time working together. Cygwin really only works well in it's own environment. Eclipse is a native Windows application. If we're properly going to support Cygwin, we need to treat it specially.

Hi Andrew,
I think I am close to finding a solution. I just identified
the problem (also thanks to Michael Luber):
The gcc.exe in Cygwin 1.7 is no longer a real "exe" file.
It is a symbolic link that can only be
handled by a cygwin shell. The real exe is now called
"gcc-3.exe". Unfortunately, CDT calls "gcc.exe"
directly when from its scannerInfoProviders. The creation
of the Process object fails and thus no
path information (defines, etc.) can be
gathered.
Compiling still works because then gcc is called
indirectedly by the created makefile which in turn
starts a sh.exe to execute gcc and thus knows how to handle
the symbolic link.

setup.exe deleted it. I learned from www.cygwin.com that sh.exe originally was a
copy of/a link to ash.exe.
In
cygwin 1.7 it is derived from bash.exe.
setup.exe ran a postinstall script to perform this
modification. But since this script was executed with one
the
shells (the old or the new one, I dont remember anymore) the file was blocked by
the running process
and
could not successfully replaced. Reinstalling the shells package solved the
problem.

Hi Nils,
What kind of project are you creating and what toolchain? Is it Makefile
Project?
Also, what problem did you have with sh.exe? Did you delete it
accidentally?
Thanks,
Andrew

Dear friends,

am stuck.
First problems was that sh.exe was deleted.
This problem is fixed.

From a previous question from Markus on
2009-01-31 I learned that
a package named "gcc" should be installed.
I only have gcc-core and do not
know how to get just gcc. Maybe I am
looking at a false trace, since when
I type "gcc" into a bash, gcc is found.
CDT can compile C source, but CDT
cannot find/resolve standard include paths anymore!
Please help....
