Mono installation workaround for CentOS6

[mario_]

PicoScope6GTK requires mono installation for operation. CentOS6 and derivatives don't provide this requirement. Yet there is workaround using packages available on opensuse.download.org server. To get mono requirement for PicoScope6GTK on Centos6, run the following steps in the terminal:

1. Configure custom repository

Code: Select all

sudo curl -o /etc/yum.repos.d/monoEL6.repo http://download.opensuse.org/repositories/Mono:/EL6/RHEL6/Mono:EL6.repo
sudo yum check-update

2. Install gdiplus dependecy

Code: Select all

sudo yum install libgdiplus

3. Install PicoScope as described in http://www.picotech.com/support/topic13431.html - Fedora 20 section

Code: Select all

sudo curl -o /etc/yum.repos.d/picoscope.repo http://labs.picotech.com/rpm/picoscope.repo
sudo rpmkeys --import http://labs.picotech.com/rpm/repodata/repomd.xml.key
sudo yum check-update
sudo yum install picoscope

4. Configure gdiplus to be used in mono
a. get the location of the library (/usr/lib64/libgdiplus.so.0 usually)

Code: Select all

sudo ldconfig -p | grep -m1 gdiplus | cut -d' ' -f4

b. edit mono config (replace vi with your favorite text editor)

Code: Select all

sudo vi /etc/mono/config

c. Insert following line before the last containing , replacing [location] with what you found in step a.

Code: Select all

d. save the file and PicoScope should work!

I'm still having some issues installing on CentOS. I get the following even after I've installed libgdiplus:

Code: Select all

Error: Package: picoscope-6.11.8-4r3.noarch (picoscope)
           Requires: mono(Microsoft.VisualBasic)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Hi spiralphenomena,

The repository doesn't provide mono-basic package. Maybe you could source it from somewhere else? For example: https://www.rpmfind.net/linux/RPM/opens ... oarch.html
(then download and rpm -i )
I'm not sure though if it won't need any more dependencies.

Hello,

I just tried to follow this procedure, but I have problems with the

Code: Select all

yum install picoscope

part.

Apparently the version of zlib is not recent enough, the version provided with CentOS 6.8 is the 1.2.3-29.

Somebody know a solution for this issue ?

Thanks in advance
