I'm browsins git code with Eclipse. I'm on a local branch called
"studio" based on master (last public commit e902e9b by Junio C
Hamano on Monday March 11 2019). I've built everything by
changing:
CFLAGS = -g -Wall (removing -O2 to have smooth trace in
debugging).
But the environment detects the following semantic errors (I
made no
edits!!!):

I can debug without problems, but what if I should trece through
one of those errors?
How can I fix them?

This situation occurs in many projects in ECLIPSE, not only git.
The
errors are likely coming from one of the error parsers that you
have enabled in your workspace. Look in the Project Properties or
Workspace Preferences under C/C++ Build/Settings in the Error
Parsers tab for your build configuration. You may have to turn off
some of those.
There is also the C/C++ General/Code Analysis Preferences setting
where you might have to turn off the problematic errors. I have
found that this is a common situation for code that is imported
into ECLIPSE from other platforms, where the GNU error and
analysis tools are overly aggressive by default.

Good luck.

Thank you I tried to disable all of them, but they all remain. For
example the variable 'active_nr' is actually never declared. That's
so strange.
Hope to
solve this all soon. I'm freezed...

It is very likely in ECLIPSE either in workstation or project settings
relating to error parsers (turn everything off). It still may be an
error parser issue. One key thing... do not use -Wall.
There are also settings about what to do in some error conditions
configured in ECLIPSE. -Wall could be probably triggering a response
from one of the error parsers. But the Semantic Error type is not
normally from the compiler; rather, it is from ECLIPSE CDT pre-
scanning the code. Anyway, check out other -W settings to disable all
warnings as a start. If you are building in Cygwin or Mingw, you
probably can ignore the ECLIPSE errors, especially if git actually
built. If you are trying to mix a managed build and a non-managed
build in the same project, you are going to be out of luck.

You mean that if I try to build the project from the shell with a make
command and then, after some work, inside Eclipse environment I could get
these semantic errors?

Yes, the semantic scanner runs independently of any build you might do. It is designed to detect code defects before compilers are involved as people are typing. It runs whenever files are modified.
