I am running Caraven build on my github repo and it complains that my compressed gds file is not the gzip format. But I did compress the gds with gzip. Could it be that I am using Git LFS to store this file?

gzip: gds/user_analog_project_wrapper.gds.gz: not in gzip format

@Manar Abdelatty: Do you know how a

.gds.gz

file could end up reporting

not in gzip format

?

@Manar Abdelatty Can you help me with this? This is my github repo: https://github.com/jhz701/class_d_audio_amplifier.git The only difference I can think of is that I am using git LFS to handle my gds file because it exceeds 100 MB and I cannot upload it directly to github.

@Hongzhe Jiang I tried opening it with klayout and it complaints that it has an unknown format. I think something went wrong when you compressed the file, Did you use the

make compress

target ?

@Hongzhe Jiang: FYI, the

make compress

target uses

gzip -n --best

. It is probably better to use the makefile target, but I have on occasion run compression from the command line.

sorry, but in which makefile can I find the make compress target?

@Hongzhe Jiang It is defined in caravel's top level makefile which is included in the user project Makefile. So, from your user project root you can run

make compress

or

make uncompress

Thanks, I will try that.
