Compiling with Ubuntu and gcc 5.4.1

[m1k6]

Hello everyone.
I'm trying to setup Ubuntu in Virtualbox to compile ML.
I installed Ubuntu 16.04 (LTS) and Mercurial.
To install gcc I followed these instructions (prebuild compiler).
After cloning the repo I adjusted the Makefile.user so it matches the paths.

Now the problem:
When using "make zip/install" to compile ML I get the following error:

Code: [Select]

marvin@Ubuntu-VM:~/magic-lantern/platform/1200D.101$ make zip
../../Makefile.inc:65: remove /home/marvin/magic-lantern/platform/1200D.101/zip

# Naming convention for Magic Lantern builds:
# General rules:
# - Always specify the camera and its firmware version number in the build name (e.g. 550d.fw109)
# - For non-release builds, specify the build date and author's (nick)name.
# - For experimental builds, add a short keyword indicating the particular feature tested.

# Examples for experimental builds:
# magiclantern-2010dec07.550d.fw108.cropmarks.a1ex.zip
# magiclantern-2010nov23.550d.fw108.selectable-audio.piers.zip

# Example for pre-release builds:
# magiclantern-2010dec17.550d.fw109.PRERELEASE.alex.zip

# magiclantern-0.2.0.rc1.550d.fw109.zip

I hope you can help me. Thanks in advance!

If you put sudo before makefile?
Wild guess.

[m1k6]

Sudo does not work. Running as root also gives permission denied. 
It's a new installation, nothing was changed.

I just googled some and it seems to be a common issue. Check if the answer isn,t already there for you. Good luck

I´m on OpenSuse, but maybe this run on Ubuntu, too

Try the Linux-tarball from here:
https://launchpad.net/gcc-arm-embedded/+download\

Download it somewhere into your home-dir. Unpack it.

Now tell the makefile.user, where this stuff is. Look into my makefile.user for an example:

Code: [Select]

ARM_PATH=/home/edgar/Programme/MagicLantern/gcc-arm-none-eabi-5_4-2016q2
GCC_VERSION=-5.4.1

HOST_CFLAGS         = -g -O3 -m32 -W -Wall -fms-extensions -std=c99
HOST_LFLAGS         = -m32
CONFIG_SITE         = n
CONFIG_PICOC        = n
CONFIG_TCC          = y
CONFIG_MEMCHECK     = y
CONFIG_MODULES      = y
Maybe, this help.

Did you succeed with "make" alone?
If not, try to modify ARM_PATH path in your Makefile.user:
ARM_PATH=/usr

[m1k6]

I followed Edgars instructions.
In addition I needed to follow this guideline.
The binaries had problems executing on a 64-bit Ubuntu.

Problem solved.
Thanks for the help!
