Ich mochte g2o installieren, aber alle meine Versuche sind gescheitert.
Infos:
Python Version: 3.10.6
Betriebssystem: Windows x64

Danke schon im voraus

Was ist g2o?
Was hast du versucht?

Du hast die Dokumentation gelesen, und die notwendigen Dinge in der Sektion "Requirements" beachtet? Und welche Fehlermeldungen bekommst du? Oder geht das alles voellig stillschweigend schief?

zuerst habe ich es mit pip install g2o probiert.
Fehlermeldung:

Code: Alles auswählen

ERROR: Could not find a version that satisfies the requirement g2o (from versions: none)
ERROR: No matching distribution found for g2o

Danach mit der Anleitung auf Github:
git clone https://github.com/uoip/g2opy.git
cd g2opy
mkdir build
cd build
cmake ..
Hier kam die Fehlermeldung:

Code: Alles auswählen

CMake Warning:
  Ignoring extra path from command line:

   ".."


CMake Error: The source directory "C:/Users/Frenik/Downloads/g2opy-master" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

make -j8
cd ..
python setup.py install

Habe keine Ahnung was ich noch probieren soll.
Grüße Frenik

Das glaube ich nicht. Die git Kommandos würden kein Verzeichnis g2opy-master nach sich ziehen. Da ist irgendwas faul. Du musst was anders/falsch gemacht haben.

Ich habe alles nochmal probiert.
bei dem Kommando cmake ..
kam folgende Fehlermeldung:

Code: Alles auswählen

CMake Error at CMakeLists.txt:4 (PROJECT):

  failed with:

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

was soll ich machen?

Hallo,

"vor" der Anleitung steht was von C-Requirements, hast du die? (Edit: das hatte __deets__ ja auch schon erwähnt, ich konnte nur keine Antwort dazu finden)
https://github.com/uoip/g2opy#g2oRequirements

Was in C:/Users/Rainer/g2opy/build/CMakeFiles/CMakeOutput.log ?

C-Requirements habe ich (Programmiere selber mit C/C++)
Inhalt von C:/Users/Rainer/g2opy/build/CMakeFiles/CMakeOutput.log:
The system is: Windows - 10.0.19043 - AMD64
The system is: Windows - 10.0.19043 - AMD64

Hast du die Fehlermeldungen mal gegoogelt?

hab ich schon gegoogeld
Hab aber nichts brauchbares gefunden
Grüße Frenik

Komisch. Ich finde da sofort Hinweise. https://stackoverflow.com/questions/705 ... lelanguage

Habe eine Teil des Problems gelöst.
Den CMAKE_C_COMPILER und den CMAKE_CXX_COMPILER ERROR habe ich jetzt gelöst.
Die Fehlermeldung:

Der Link den ich gepostet habe erklärt das doch. Du hast kein nmake.

habe nmake jetzt installiert.
Bekomme jetzt folgende Fehlermeldung:

Da fehlt eine Bibliothek. Was man sich rausfindet, wenn man die Fehlermeldung mal googelt. Machst du das auch mal von selbst? Denn ich komme mir hier vor wie dein Tippknecht. Ein bisschen Eigeninitiative schadet nicht. Sonst wird’s eh nix.

Ich würde dir auch nachdrücklich zu Linux als Hostsystem raten. Denn das sind Säcke voll Abhängigkeiten, die unter Linux leicht zu installieren sind. Nicht so aber unter Windows. Siehe https://github.com/jlblancoc/suitespars ... or-windows für eine Weg. Aber der ist steinig und bedarf etwas mehr Engagement als bisher beobachtbar war.

Danke für die Antwort
Ich werde es mal mit Linux probieren.
