Arch Linux User Repository

Please have a look at

https://github.com/capitalaslash/archlinux-magics

I updated to the latest version, with improvements to the build logic, dependencies and a gcc 11 patch. Let me know how we can integrate it here

I could not build 4.5.3 with proj 8.0 as reported here, but updating to 4.6.0 worked.

adjusting PKGBUILD

pkgver=4.6.0
md5sums=('570d9888fc794b7c72c0a09fc9210dc3')

I confirm that 4.5.3 works. The following changes to PKGBUILD solved the problem for me:

I got the same error as @mpejcoch on 2020-05-15 but was successfully able to build and install version 4.5.3 downloaded here[1] and following their instructions here[2]. I hope this helps someone.

Unfortunately even the 4.3.3 version won't build.

Hi, I tried to build it via yay without success.

2 questions arose:

• Do you have any idea where this error could come from:

[ 98%] Building C object libemos-sp/CMakeFiles/emos_sp.dir/pbio/gbyte_le.c.o
[ 98%] Linking Fortran static library ../lib/libemos.a
[ 98%] Built target emos_sp
make: *** [Makefile:163: all] Error 2
==> ERROR: A failure occurred in build().
    Aborting...
Error making: emos

• is there another pkbuild building it with python 3?

Thanks in advance for your input and sorry for annoying :)

happy new year!

I tried a fresh install and had to install python2-jinja to survive the cmake step. might be worth adding to the dependencies

cheers!

I was able to compile it with python 3 as mentioned here https://confluence.ecmwf.int/display/MAGP/Magics

Also, I added python-jinja as another dependency

I get this error When building:

Scanning dependencies of target magics_params
[  1%] Generating params/Akima474MethodAttributes.h, params/Akima474MethodAttributes.cc
Traceback (most recent call last):
  File "/tmp/yaourt-tmp-adriano/aur-magics++/src/Magics-3.0.0-Source/src/../tools/xml2cc.py", line 2, in <module>

==> ERROR: A failure occurred in build().

However the /tmp/yaourt-tmp-adriano/aur-magics++/src/Magics-3.0.0-Source/src/../tools/xml2cc.py seems fine, I can load jinja2 without problems.

Installing python2-jinja fixes it.
