[Solved] Compilation fails on Debian.

[wmayer]

What do you think of this ? :

As long as it compiles it's OK. In C++ you have several ways to use a class of a name space. Either you write the name space as prefix to the class name (e.g. std::istream) or you write "using std::istream" or "using namespace std" after the include statements.

[fcaduser]

OK. So should I proceed step by step and report ? And each stop pointed will necessarily need the modification of the code by you (name space clarification) ?

There is only the "issue" that gcc9 in sid produces thousands more warnings when compiling.

Could you at some point provide a log file with all these warnings, please?

sure!

Note, it is 15MB in size after unpacking! And just ignore the first 4287 lines, it is the output of pbuilder.
As a reference, here is the last log which ran with gcc8:

      5 [-Wunused-but-set-variable]

So I think it is nothing of real concern, but a friend of mine already had some troubles with the new gcc9 and segfaults, as the compiler does things differently

Thanks a lot! When I recently built the code with clang my log file had a size of 120 MB but it could be reduced to around 50 files that needed to be fixed.

@wmayer

Did you see my question ? My point was : should I systematically report to you the recurrent problem with the lack of std:: ? I mean, you have to alter the code, I suppose ?

The previous achieved compilation I did was on 30 July. I don't know why all these stumbles appear now (no modification between of my gcc, environment, etc.)

Yesterday I pushed some fixes to the repo. So, update your local repo and then build FreeCAD again. And yes, report all errors you encounter to this thread.

There are so many reasons why this can have changed. So, it's useless to try to find the root cause of it.

@wmayer

OK, so I resume the process.

[fcaduser]

OK, so I've just clone again the repo.

Fixed. Next attempt.
