Re: DSO missing from command line when installing medm

[Florian Feldbauer <florian@ep1.ruhr-uni-bochum.de>]

Hey,

I'm neither using MEDM nor Ubuntu, so I can only guess.
From what I found using Google, it seems you need to link against libld which is not done by default.

You could try to change the line
"USR_LIBS_Linux = Xm Xt Xp Xmu X11 Xext"
to
"USR_LIBS_Linux = Xm Xt Xp Xmu X11 Xext ld"
in medm/Makefile to include the library in the
build process.

Cheers
Florian

I didn't change anything in the medm folder and I still can't solve this after search on Google . I think I must have lost something . Could you help me?
Thank you !
