Unable to compile on Fedora 32

[huaracheguarache]

As the title states, I'm unable to compile netperf on Fedora 32. What I've done so far is run (without any apparent issues):

./autogen.sh
./configure --enable-demo

When I run make I get the following error:

[michael@localhost netperf]$ make

rm -f stamp-h1
touch config.h.in
cd . && /bin/sh ./config.status config.h

Ok, I got it to work. Fedora 32 uses GCC 10 which by default compiles with -fno-common. As a workaround you can pass -fcommon to GCC via make:

make CFLAGS="-fcommon"

I found this workaround here: https://gcc.gnu.org/gcc-10/porting_to.html

[itayave]

Thanks, Are you planning to provide a fix? if so, when?

[huaracheguarache]

@itayave Fixing the source code? I don't plan on doing that since I have no experience with C.

[guidosarducci]

Regarding a code fix, see https://github.com/openwrt/packages/pull/13058 as an example.

[westurner]

Would https://github.com/HewlettPackard/netperf/pull/46 "nettest_omni: Remove duplicate variable definitions" fix this issue as well?
