All,
Using the tool chain that comes with the FVP package that I downloaded last month (Oct 2017), I'm trying to compile the Splash2 benchmark to execute on the latest FVP platform and seeing a compilation issue that goes like this (please see below)
To reproduce:
1. download the benchmark from here and follow _all_ the instructions in the homepage: http://www.capsl.udel.edu/splash/Download.html 2. edit the makefile.config under /splash2/codes to use linaro toolchain and choose POSIX_BARRIER for the MACROS section (I've pasted my makefile.config here as well - you will have to modify the toolchain paths to suit your setup) 3. cd to splash2/codes/apps/ocean/contiguous_partitions 4. make (and you will see the problem)
Please help. Thanks.

Your explicit linking flags might be causing the problem. Try removing "-lgcc -lc" from your command line.
You can notice in the output that compiler driver adds "--start-group -lgcc -lc ... --end-group" options, which is how -lgcc and -lc should be used when linking.

Hello Maxim
Step#1 Using the new 7.1 tool chain version that you pointed me to _and_ Step#2 removing the -lgcc -lc flags
Now, I can get to built the sources as intended. I also tried to rebuild by linux kernel and busybox with the 7.1 tools along with the multi-threaded application - and it works as intended So, I suppose there is no need to file a bug anymore? Note: the bug is still present should we use any 6.x versions (despite including Step#2)
In any case, I am indebted to your technical support.
Many Thanks,

and choose POSIX_BARRIER for the MACROS section (I've pasted my makefile.config here as well - you will have to
modify the
toolchain paths to suit your setup) 3. cd to splash2/codes/apps/ocean/contiguous_partitions 4. make (and you will see the problem)
Please help. Thanks.

Your explicit linking flags might be causing the problem. Try removing
"-lgcc -lc" from your command line.
You can notice in the output that compiler driver adds "--start-group
-lgcc -lc ... --end-group" options, which is how -lgcc and -lc should be used when linking.
