init.sh fails with a GraphBLAS compilation error

[hagabb]

I'm trying to test the GraphBLAS reference implementation on the small data set. The following command used to work, but now fails with a GraphBLAS compilation error:

devcloud@40a6b79d144c:~/ldbc_graphalytics_platforms_graphblas$ ./scripts/init.sh ~/graphalytics_data/S/

Hi Henry, this repository moved to SuiteSparse:GraphBLAS v8. https://github.com/ldbc/ldbc_graphalytics_platforms_graphblas/blob/main/bin/sh/install-graphblas.sh#L8

This is currently only available as a draft version but it is expected to be complete soon: https://github.com/DrTimothyAldenDavis/GraphBLAS/releases/tag/v8.0.0.draft9

[szarnyasg]

Okay, so there were two issues:

1) The change from SuiteSparse:GraphBLAS v7 to v8(draft). 2) The CDLP algorithm was improved by @pcostanza in PR https://github.com/GraphBLAS/LAGraph/pull/192 and the glue code in this repository had to be updated to accommodate those changes.

The CI is green now.

I pulled the updated repo this morning and it's working again.
