Hi Tianfei,

To reproduce this, assume using Ubuntu 20.04.
1. Install libfdt (It will include ifpga driver from drivers/raw/ifpga/base)
    $ sudo apt-get install libfdt-dev
2. configure DPDK library
    $ meson build
3. check libdpdk.pc file in build/meson-private/libdpdk.pc. It will include path to librt.so without this patch.

Regards,
Alim Hussin

I have checked the libdpdk.pc and got the different between with and without this patch.
Without this patch, there are a full path for librt.so in libdpdk.pc. With this patch, it provide "-lrt" in libdpdk.pc.

This patch looks good for me.

I can't find the original mail to dev@dpdk.org and patchwork did not help.
Please, can you resubmit this patch?

Also copy Bruce as this touches a meson subtlety I was not aware of,
and he should probably have a look.


Thanks.

Thanks for flagging this to me, I wasn't aware of the subtlety here at all,
but it's good to know for future reference. If asked, I would generally
have recommended using find_library without the "lib" prefix on the library
name, but I had no idea using with or without leads to different output.

Finding with "librt" keyword would give the output with full path of librt such
as /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/librt.so
instead of -lrt in libdpdk.pc pkg-config file.

Assume find_library() will prepend "lib", thus remove "lib" from "librt"
keyword. The output will shows as -lrt.

This will cause an issue when compile DPDK app with static library as the
path of librt has been hard-coded in the libdpdk.pc file.

This patch is resent, because original patch was not in the patchwork as David
reminded.

But first patch already has acks, I am moving them here:

Also I can produce the same, and patch looks good to me.


But it fails to apply clearly because of the white-space differences, and this
prevents CI running.

@Mohamad, can you please send a new version rebasing on top of latest code?
Please keep the acks above in the next version commit log, since the change will
be only white-space.

Thanks,
ferruh

From: Mohamad Noor Alim Hussin <mohamad.noor.alim.hussin@intel.com>

Finding with "librt" keyword would give the output with
full path of librt such as
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/librt.so
instead of -lrt in libdpdk.pc pkg-config file.

Assume find_library() will prepend "lib", thus remove
"lib" from "librt" keyword. The output will shows
as -lrt.

This will cause an issue when compile DPDK app with
static library as the path of librt has been hard-coded
in the libdpdk.pc file.
