I have recently upgraded from unRAID v5 to v6.  I was able to compile Mediainfo from source on v5.  I installed gcc and g++ compiler packages at boot.  I have installed gcc and g++ and make 64bit packages from here: http://mirrors.slackware.com/slackware/slackware64-14.1/slackware64/d/

 

When I run the compile script "CLI_Compile.sh" I get the following:

 

checking build system type... x86_64-unknown-linux-gnu

checking for a BSD-compatible install... /usr/bin/ginstall -c

checking whether build environment is sane... yes

checking for a thread-safe mkdir -p... /usr/bin/mkdir -p

checking for gawk... gawk

checking whether make sets $(MAKE)... yes

checking whether make supports nested variables... yes

checking for gcc... gcc

[glow=red,2,300]checking whether the C compiler works... no

configure: error: in `/mnt/APPS/MediaInfo_CLI_GNU_FromSource/ZenLib/Project/GNU/Library':

configure: error: C compiler cannot create executables[/glow]

See `config.log' for more details

What's missing from v5 that I need in v6 to get gcc to work?

I figured it out by looking at the "config.log".  Every time it had an error, I would need to download a package with a library or function which got me a little further each time.  In V5 the gcc package through unMenu installed: gcc, make, binutils, glibc, and kernel-headers.  That was the difference between V5 and V6 ( I am not running unMENU on V6 yet).

 

I ended up with these packages in my /boot/extra folder:

binutils-2.23.52.0.1-x86_64-2.txz

gcc-4.8.2-x86_64-1.txz

gcc-g++-4.8.2-x86_64-1.txz

git-1.8.4-x86_64-1.txz

glibc-2.17-x86_64-7.txz

kernel-headers-3.10.17-x86-3.txz

libmpc-0.8.2-x86_64-2.txz

make-3.82-x86_64-4.txz

 

The packages were downloaded from: http://mirrors.slackware.com/slackware/slackware64-14.1/slackware64/

 

Now I can compile MediaInfo from source and use it in my YAMJ scans.
