symbol lookup error

Hi,

Some additional information.

After another weekend reboot, some of the previously mentioned behavior returned (with the exception that the .lck files were not created).  When attempting to open a design file with 7.5, the same symbol lookup error occurred.  Reverting back to 7.1 by changing the .alias did not clear the error.  Rebooting with .alias pointing to 7.5 allowed the files to open successfully (error does not occur).

It appears that the symbol lookup error is somehow related to whether and how the .alias update is invoked; through reboot or source .alias command.  Subsequent reboots may or may not create the situation in which the error occurs.

Any insight would be greatly appreciated.  Thanks.

Hi,

 

I recently upgraded from Eagle 7.1 to 7.5.  After the upgrade, I was

able to load multiple prior designs successfully.

 

After restarting my Linux machine over the weekend, I got an error when

attempting to open either a prior design or a new design (no content):

 

eagle: symbol lookup error: eagle: undefined symbol:

EC_get_builtin_curves

 

If I attempted to open the same file a second time I got a "file

locking" window indicating that the file is locked by owner (me).   I

was reluctant to choose "save as" at this point as the "hour glass" was

still rotating, implying that the state of the software was not happy.

 

In the design directory, files were created after attempting to open

with 7.5 as follows:

filenam.brd.lck

filename.sch.lck

 

After .alias was changed to revert back to 7.1  and the .lck files were

removed, I could successfully open prior designs.  Additionally,

changing .alias to 7.5 again (for the second time) successfully opens

existing files.  I also disabled file locking.  Subsequent reboot allows

multiple files to open successfully.  At the moment, it seems all is

well as far as opening new/prior designs but the unexplained behavior is

concerning.

 

 

Can you provide any insight into the original "symbol lookup error " and

whether this is a real error going forward with 7.5?  Thanks.

 

 

Hi John,

I hope you're doing well. This is an odd error, that I've never seen

before.

What is this .alias that you are referring to? Is this a hidden file on

your system?

Hi Jorge,

Yes, .alias is a hidden file on my system.  It contains the additions for all the various engineering tools used by the team such as PYTHON, MATLAB, FPGA tools, and EAGLE.

For EAGLE, the latest using 7.5 reads as follows:

#Additions for Eagle

#export EAGLE_PATH=/home/tools/eagle/eagle-lin-eng-5.11.0

#export EAGLE_PATH=/home/tools/eagle/eagle-lin-eng-6.4.0

#export EAGLE_PATH=/home/tools/eagle/eagle-lin-eng-6.5.0

#export EAGLE_PATH=/home/tools/eagle/eagle-lin-eng-7.1.0

export EAGLE_PATH=/home/tools/eagle/eagle-lin-eng-7.5.0

export EAGLE_PATH_BIN=$EAGLE_PATH/bin

export EAGLE_PATH_LIB=$EAGLE_PATH/eagle_libs

In order to upgrade from 7.1 to 7.5, I only add the latest 7.5 export line and comment out (#) previous 7.1 line.  After saving the change, then use the command "source .alias" to invoke the changes.  Hope this is clear.

Also fyi, a coworker has the same error when using 7.5.

Taking this issue up with the devs.

I'll post once I have a response.
