# Step 1.
|
||
|
|
|
||
|
|
Make sure you have the quay.io/pypa/manylinux1_x86_64 image.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker images
|
||
|
|
REPOSITORY TAG IMAGE ID CREATED SIZE
|
||
|
|
quay.io/pypa/manylinux1_x86_64 latest 1c8429c548f2 2 months ago 879MB
|
||
|
|
hello-world latest 4ab4c602aa5e 3 months ago 1.84kB
|
||
|
|
# My image was old:
|
||
|
|
$ docker pull quay.io/pypa/manylinux1_x86_64

|

|
|
# Step 2.
|
||
|
|
|
||
|
|
This step was inspired by https://dev.to/jibinliu/how-to-persist-data-in-docker-container-2m72
|
||
|
|
Create a volume for klayout. This is necessary because docker containers don't persist data.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker volume create klayout-persist
|
||
|
|
$ docker volume inspect klayout-persist
|
||
|
|
[
|
||
|
|
{
|
||
|
|
"CreatedAt": "2018-12-18T15:01:48Z",
|
||
|
|
"Driver": "local",
|
||
|
|
"Labels": {},
|
||
|
|
"Mountpoint": "/var/lib/docker/volumes/klayout-persist/_data",
|
||
|
|
"Name": "klayout-persist",
|
||
|
|
"Options": {},
|
||
|
|
"Scope": "local"
|
||
|
|
}
|
||
|
|
]
|
||
|
|
```
|
||
|
|
|
||
|
|
# Step 3.
|
||
|
|
|
||
|
|
Build image `myimage` with:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker build -t myimage:latest .
|
||
|
|
```
|
||
|
|
|
||
|
|
This creates an image called `myimage` (temporary). This image will not overwrite old ones. Tip: prune old, unused images with `docker image prune`.
|
||
|
|
|
||
|
|
Then I run the docker with a terminal shell and load the volume klayout-persist in /persist:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker run --name klayout --mount source=klayout-persist,target=/persist -it myimage
|
||
|
|
```
|
||
|
|
|
||
|
|
# Step 4.
|
||
|
|
|
||
|
|
In the shell, pull master from klayout.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd /persist
|
||
|
|
git clone https://github.com/lightwave-lab/klayout.git
|
||
|
|
mkdir -p wheelhouse
|
||
|
|
cd klayout
|
||
|
|
# make wheel with python 3.6 (for example)
|
||
|
|
/opt/python/cp36-cp36m/bin/python setup.py bdist_wheel -d /persist/wheelhouse/
|
||
|
|
cd /persist
|
||
|
|
auditwheel repair "wheelhouse/klayout-0.26.0.dev8-cp36-cp36m-linux_x86_64.whl" -w wheelhouse/
|
||
|
|
# Need to manually fix the wheel
|
||
|
|
#/opt/python/cp36-cp36m/bin/pip install klayout --no-index -f /wheelhouse
|
||
|
|
```
|
||
|
|
|
||
|
|
The produced wheel from auditwheel, klayout-0.26.0.dev8-cp36-cp36m-manylinux1_x86_64.whl, is defective in the following way: dbcore.so etc. have RPATHs reset to `$ORIGIN/.libs`, so we need to move all .so's `lib_*` into `.libs`, as well as `db_plugins`. We also need to change the dist-info/RECORD file paths. This is a bug from auditwheel, it should either have added a new RPATH, $ORIGIN/.libs, where it places libz, libcurl, libexpat, instead of renaming the existing ones, or moved the files to the right place.
|
||
|
|
|
||
|
|
|
||
|
|
Procedure to fix the wheel:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
unzip wheelhouse/klayout-0.26.0.dev8-cp36-cp36m-manylinux1_x86_64.whl -d tempwheel
|
||
|
|
cd tempwheel/klayout
|
||
|
|
mv lib_* db_plugins .libs/
|
||
|
|
cd ../klayout-0.26.0.dev8.dist-info/
|
||
|
|
sed -i 's/^klayout\/lib_/klayout\/.libs\/lib_/g' RECORD
|
||
|
|
sed -i 's/^klayout\/db_plugins/klayout\/.libs\/db_plugins/g' RECORD
|
||
|
|
cd ../
|
||
|
|
rm -f ../wheelhouse/klayout-0.26.0.dev8-cp36-cp36m-manylinux1_x86_64.whl
|
||
|
|
zip -r ../wheelhouse/klayout-0.26.0.dev8-cp36-cp36m-manylinux1_x86_64.whl ./*
|
||
|
|
cd ..
|
||
|
|
rm -rf tempwheel
|
||
|
|
```
|
||
|
|
|
||
|
|
Now we can install and test:
|
||
|
|
```bash
|
||
|
|
/opt/python/cp36-cp36m/bin/pip install klayout --no-index -f /persist/wheelhouse
|
||
|
|
cd /persist/klayout
|
||
|
|
/opt/python/cp36-cp36m/bin/python -m unittest testdata/pymod/import_db.py testdata/pymod/import_rdb.py testdata/pymod/import_tl.py
|
||
|
|
# Tests passed!
|
||
|
|
```
