Bug ID: 1422
Summary: vfio-pci driver fails to compile on Alpine Linux
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: ahassick@iol.unh.edu
Target Milestone: ---
The DPDK main branch, on commit 7e06c0de1952d3109a5b0c4779d7e7d8059c9d78,
encounters a compilation error on Alpine Linux. This appears to be a new issue
caused by us upgrading our container image, which includes newer versions of
GCC and musl.
GCC version: (Alpine 13.2.1_git20231014) 13.2.1 20231014
musl-libc version: 1.2.4_git20230717-r4
Kernel: 5.4.0-167 generic
Output from GCC:
../drivers/bus/pci/linux/pci_vfio.c: In function 'pci_vfio_read_config':
../drivers/bus/pci/linux/pci_vfio.c:83:16: warning: implicit declaration of
function 'pread64'; did you mean 'pread'? [-Wimplicit-function-declaration]
