[Resolved] Can somebody help me build on Ubuntu 20.04 (but this also failed on Ubuntu 19.10)

Hi,

I am following the exact directions found here:
and am using precompiled libraries. Unfortunately it does not build. Here is stdout:

In file included from /usr/include/x86_64-linux-gnu/sys/stat.h:446,
             from /home/optonox/blender-git/lib/linux_centos7_x86_64/python/include/python3.7m/pyport.h:224,

make: *** [GNUmakefile:304: all] Error 2

This program will not allow me to upload the stdout log file I made because I am a new user, so I am attaching it below.

Please let me know what to do to get this to build. Thanks

Hi, can you add the complete log with make -j1 to https://pasteall.org/
or similar, please?
Attach CMakeCache.txt here, too,

Cheers, mib

3

Seems to be a gcc issue, unsure how much we can do about this from the blender side, i’d take this up with your distro.

4

Hey, can you successfully build make lite ? Also, if you’re having a gcc issue, it might be worth it to try using a different gcc version instead: (Wrong GCC version For CUDA (Linux) -- How to solve)

I’m running Kubuntu 19.10 and haven’t had any difficulty building since I quit trying to build the dependencies myself. I haven’t had any gcc issues except for CUDA.

5

make -j1: output is here

As I new user I can’t upload files so there is a link to the CMakeCache.txt

6

make lite also fails. Here is the output from that

7

it’s picking up libpng from outside the lib folder in your cmakecache.txt point PNG_LIBRARY_RELEASE:FILEPATH=/usr/local/lib/libpng.a to the one in the blender lib folder rather than the one from /usr

9

Can you explain the best way for me to do this?

10

you take a text editor of your choice and you make the change?

11

Nice! That worked! Thank you so much.

And sorry, earlier I meant how to make sure this doesn’t happen in the future because right now it looks like I have to build, update CMakeCache.txt, then rebuild…

I really appreciate your help.

12

make -j1

Any reason why you’re building with -j1? That means it is only using one CPU core. I have 16, so I usually build with -j15. Leaving off the -j parameter entirely will use all of your cores.

13

It was suggested to do so above.

14

Ah, so it was.

The reason I suggested make lite, by the way, is because make lite is the bare-minimum Blender, it doesn’t include most features, not even Cycles! So when you have a build-failure with lite, you can rule out many possible problems. In particular, the errors in the audaspace library in your first post made me suspect there could be a problem building the audio module. I think I was wrong about that, though. There have been times when I could build lite and not full. Anyways, if you go on to try and build CUDA or OPTIX, you’ll want to look at the “use older versions of gcc” post I linked above.

15

when diagnosing issues we generally ask to build with -j1 since people tend to give just the last 10-15 lines of the build log. when building with multiple threads the actual error is much higher up in the build log, while with -j 1 it sits nicely at the end.
