Error in startup script: can't read "varval": was created by poolspieler
Hi @all,
I want to compile and build LinuxCNC from source code.
I just installed git and the other packages in order to get the project compiled.
I run this commands:
./autogen.sh
./configure
make
sudo make setuid
cd ..
. scripts/rip-environment
linuxcnc

But after I run linuxcnc, I get this error:
cnc@cnc-VM:~/emc2-dev$ linuxcnc
LINUXCNC - 2.6.0~pre
Error in startup script: can't read "varval": no such variable
    while executing
"return $varval"
    (procedure "getVal" line 8)
    invoked from within
"getVal $rcstring PICKCONFIG LAST_CONFIG "
    (procedure "initialize_config" line 15)
    invoked from within
"initialize_config"
    invoked from within
"set last_ini [initialize_config]"
    (file "/home/cnc/emc2-dev/tcl/bin/pickconfig.tcl" line 204)
cnc@cnc-VM:~/emc2-dev$

I already googled this issue - but I didn't find any useful information.

Two hints:
- I checked out the latest version --> should I use 2.5.0 instead?
- I compiled it on a virtual machine (VirtualBox)

Best Regards,

Andy

Hi

I run this commands:
Code:
./autogen.sh
./configure
make
sudo make setuid
cd ..
. scripts/rip-environment
linuxcnc


The sequence for a RIP install used to be
./configure --enable-run-in-place
make
make setuid
cd ../
. ./scripts/emc_environment
emc

Allowing for re-branding changes, check what type of build configure does without any switches (./configure --help)

It used to be a user build, ie for installation into the file system.

I am wondering if you have done a normal installable build and are trying to use it as RIP

I checked out the latest version --> should I use 2.5.0 instead?

I would just use 2.5 unless you want any of the features only in the master.

Be aware that any snapshot you download may be broken in some respect.

Hi ArcEye,
thank you for your answer!

Now I checked out the 2.5.0 Release and compiled it.

I ran this commands:
make
make setuid
cd ../
. ./scripts/emc_environment
emc

But there is NO ./scripts/emc_environment file.
What I am doing wrong?
Here are some lines of my console:

In 2.5 it is rip-environment.

Hi

You misunderstood me - that's what the

Allowing for re-branding changes

was about.
I am sure the new script IS called rip_environment, everything with emc in it was changed.

What you don't seem to have done is set configure for a RIP installation
./configure --enable-run-in-place
or checked what type of build you get by default.

My version of 2.5 was a pre-release one but configure still took
--prefix=/usr for a system install, and
--enable-run-in-place for a RIP install

The reason I guessed your paths are screwed up is that pickconfig was a tcl program to try to determine the correct .ini file to use, in the old emc script.

Assuming that your ~/linuxcnc directory exists and has some configs in it, need to make sure you have the correct build and environment for RIP.

Hi Again

JT just answered one part whilst I was still writing and I can confirm that --enable-run-in-place appears to have been deprecated and configure should make a RIP build if you do not specify a --prefix=

I have just downloaded 2.5 from here
linuxcnc.org/hardy/dists/lucid/linuxcnc2...inuxcnc_2.5.0.tar.gz
( don't ask me why it is /hardy/dists/lucid/ seems to be the same file as at /lucid/dists/lucid/ !?)

compiled and run it with
./configure --enable-run-in-place (not necessary but makes sure)
make
make setuid
cd ../
. ./scripts/rip_environment
linuxcnc
sequence
without any problems.

Try that link and compile as above

regards

Hi ArcEye,
thank you for your effort!

I downloaded the tar-file and executed following sequence of commands:
./configure --enable-run-in-place
make
sudo make setuid
. ./scripts/rip-environment

--> it is still the same result:

I could imagine two (or three) reasons:
- there is a problem with the installed tcl-version or with an other package
- I am running it in a virtual machine - perhaps I should test it on a real machine
- I am a little bit stupid ;)

Hi

I doubt that configure would finish if the python / tk /tcl packages were not right

- I am running it in a virtual machine - perhaps I should test it on a real machine

That is more likely - looks like it cannot find the configs for whatever reason

- I am a little bit stupid

Doesn't seem likely, you got this far!:)

Thank you :silly:

Ok, I will try it on my real CNC PC.
What do you mean, should I remove the preinstalled LinuxCNC packages (from the Ubuntu LiveCd installation) first?

Andy

No, the whole point of a RIP build is that you can have as many as you like without interfering with the installed version.
I think I have 5 now, with the test build I did just now of 2.5.
