Subject: [dpdk-dev] [PATCH v2 4/4] ifpgai_rawdev: fix the clang compiling issue
Date: Tue, 15 May 2018 05:23:47 -0400	[thread overview]
Message-ID: <1526376227-25534-4-git-send-email-gavin.hu@arm.com> (raw)
In-Reply-To: <1526376227-25534-1-git-send-email-gavin.hu@arm.com>

Newly introduced #pragma pack(1) in the header file caused comipiling
issues for the files who included it.

In file included from ~/dpdk/drivers/raw/ifpga_rawdev/base/ifpga_fme_dperf.c:5:
In file included from ~/dpdk/drivers/raw/ifpga_rawdev/base/ifpga_feature_dev.h:8:
~/dpdk/drivers/raw/ifpga_rawdev/base/ifpga_hw.h:8:10: error: the current #pragma
pack aligment value is modified in the included file [-Werror,-Wpragma-pack]
~/dpdk/drivers/raw/ifpga_rawdev/base/ifpga_defines.h:100:9: note: previous
'#pragma pack' directive that modifies alignment is here.

The fix is to change the #pragma pack alignment locally and not have
effect on other files who included this header file.
