RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Pascal Dupuis 2021-11-27 20:21:13 UTC
Description of problem: the clang family of compilers does not contain the "flang" front-end to compile Fortran code. I need it to install R packages. I'm testing the ability to use a LLVM-based toolchain to generate R binary packages.


Version-Release number of selected component (if applicable): clang-12.0.1


How reproducible: I tried bulding flang myself from Fedora 34 flang-12.0.1 srpm, but it fails while generating the doc


Steps to Reproduce:
1. cd rpmbuild
2. [setup the tree from flang-12.0.1]
3. rpmbuild  -bb SPECS/flang.spec

Actual results: no rpm generated


Expected results: rpm generated


Additional info: the rpm in Fedora 34 can not be installed at it requires a glibc2 which is ahead of CentOS Stream

I had to patch the spec file as follows:

We currently do not have plans to add flang to RHEL.  You can use gfortran and clang together if you still want to use clang for C/C++.
