Arch Linux User Repository

I do love how Arch makes you learn...

Eventually just by studying the wiki in relation to all things PKGBUILD and makepkg, I discovered that I could use the following line in the build() function of PKGBUILD:

'export HAVE_openexr="yes"'

All now installed and seems to be working.

Thanks again for the hard work

@pingplug cheers for the input. I know what you're getting at, just figuring out how to go about it. It'll be in the wiki somewhere ;)

I can not figure out why, use system openexr instead.

Please ignore my previous comment - I had missed some key points.

I realise now that '-lpthread' is of course not involved at all.
The last lines during compile leading to the error that I faced are at the bottom.

I believe it means that '-lhalf' (perhaps) is either not written in the correct order for compiler, or perhaps is not included at all.

However, I do not know where to make/test the necessary edit - in the Makefile perhaps?

Or is it perhaps solely an issue contained within "libIlmImf.a(ImfDwaCompressor.o)", which is part of third party openexr?
This is already an object so I guess if this is where the problem lies, I can not make the necessary changes to correct it.

Sorry for the lengthy text...

Getting an error involving:
usr/lib/libHalf.so.12: error adding symbols: DSO missing from command line
I believe it is this that is breaking the compile for me.

Any ideas how to rectify?

I am presently attempting an install using 'yaourt -G', etc - rather than an automated yaourt build, on the chance that I can find and edit the appropriate command to include '-lpthread' which may fix the issue (see https://stackoverflow.com/questions/19901934/strange-linking-error-dso-missing-from-command-line) but I am not greatly experienced with this.

Cheers
