[Solved] Compilation fails on Debian.

[fcaduser]

Hi FC people.

I've just pulled the last code (which file holds the exact code version ?)
And so it fails.

My system : Linux station1 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u5 (2019-08-11) x86_64 GNU/Linux

make output :

Thank you.

I see. I think the problem is that istream lacks of the std:: prefix while the use of the ostream class has the needed prefix.
So can you just open the file in an editor and add std:: before istream in the lines 183 and 188?

Let me know if this fixes the failure so we can push the change to the repository.

[fcaduser]

grep istream /home/mainuser/softwares/freecad_source/src/3rdParty/salomesmesh/inc/Rn.h

friend std::istream& operator >> (std::istream& f, R2 & P)
friend std::istream& operator >> (std::istream& f, R2 * P)
friend std::istream& operator >> (std::istream& f, R3 & P)
friend std::istream& operator >> (std::istream& f, R3 * P)
friend istream& operator >>(istream& f, R4 & P)
friend istream& operator >>(istream& f, R4 * P)

Just edit and specify the exact namespace of istream in the header (of the two last lines) ? That's all ?

[fcaduser]

Did it, I try again and will report.

1) The compilation has been further, you can modify "src/3rdParty/salomesmesh/inc/Rn.h".

2) But a second problem appeared.

For me Debain 10 compiles fine. Here my script:

Code: Select all

As far as i know the DCMAKE_CXX_COMPILER and DCMAKE_CXX_FLAGS have an impact on salomemesh. Correct me if i am wrong.

@user 1234

Thank you. Are you using Stretch or Buster ? I'm still on Stretch but I'm planing to switch to Buster during september.

[user1234]

Debian 10 (i think that is Buster). But the procedure should be the same. Maybe you have a other Qt or Python version. But this should not impact on salomemesh. But you need pyside2 id you built it with Qt5 and Python 3.x . I do not know if Debian 9 have this.

fyi: I use Debian 10 a very long time. I do not have any problem with that.

Greetings

AFAIK the build dependencies are not met in stretch. You need at least buster or backport the dependencies yourself.
I builded on buster sucessful, and bullseye and sid are working even better. There is only the "issue" that gcc9 in sid produces thousands more warnings when compiling. I use this to compile: https://github.com/reox/FreeCAD_gitpack ... bian/rules

[fcaduser]

Can you type "uname -a" in a command line, please ?

Yes, I hope it will entail only little adjustment.
