I want to run software for initial bootup, I have gone through Links and Makefile and ran below command
make software PROGRAM=hello TARGET=design-rtl CONFIGURATION=debug
Initially, I was facing this error with os6
"configure:2877: gcc -V >&5
gcc: error: unrecognized command line option ‘-V’
gcc: fatal error: no input files
compilation terminated.
configure:2888: $? = 1
configure:2877: gcc -qversion >&5
gcc: error: unrecognized command line option ‘-qversion’; did you mean ‘–version’?
"
After that I tried running with os7 and could see below error
"
configure:2639: result: gcc
configure:2868: checking for C compiler version
configure:2877: gcc --version >&5
gcc: /lib64/libc.so.6: version GLIBC_2.14' not found (required by gcc) configure:2888: $? = 1 configure:2877: gcc -v >&5 gcc: /lib64/libc.so.6: version GLIBC_2.14’ not found (required by gcc)
configure:2888: $? = 1
configure:2877: gcc -V >&5
gcc: /lib64/libc.so.6: version `GLIBC_2.14’ not found (required by gcc)
"
I’m very new to this environment, not sure what i’m missing. I would appreciate for any help.
"configure:2877: gcc -V >&5

This isn’t an error. This is normal. The configure script is probing the compiler to see what command line options it accepts. Different compilers from different vendors support different command line options, so the configure script just tries all possible options to find the one that works.
configure:2877: gcc --version >&5
gcc: /lib64/libc.so.6: version GLIBC_2.14' not found (required by gcc)
This is a problem with your OS. It looks like a mismatch between your compiler and your GNU C library which is odd. Not clear how that could happen offhand. If the “gcc” compiler you are using the one in /usr/bin/gcc, and if not, where did you get it from?
Your reference to “os6” and “os7” is ambiguous, as a lot of different OS vendors have different operating systems with version 6 and version 7. However, I’ll guess that you have RHEL/CentOS 6 and 7 as that seems to match the glibc 2.14 error. RHEL/CentOS6 originally shipped with glibc 2.12, and RHEL/CentOS7 originally shipped with 2.17. So maybe there was an upgrade to RHEL/Centos6 that added glibc 2.14, and you are missing that update.
Another issue here is that it looks like you are trying to build freedom-e-sdk, but that requires a RISC-V compiler. Do you have one? This is not part of freedom-e-sdk. You can build from from sifive/freedom-tools, or download one from our web site. We also have an eclipse based environment that includes a toolchain and freedom-e-sdk libraries.
You need to reduce the size of the text section so that it will fit in the rom that you have.
With riscv-gnu-toolchain, you can use --specs=nano.specs to use an alternative newlib-nano C library that is smaller than the default newlib C library. This may solve the problem.
You can use tools like objdump and readelf to look at your binary, and figure out why it is too large. You can get a list of function sorted from largest to smallest by using “nm --print-size --sort-size --reverse-sort a.out”.
The default risc-v setup already has “–specs=nano.specs” and for FGPA target its proceeding perfectly with no issues and generating the hex file.
FGPA command : make PROGRAM=hello TARGET=design-vcu118 CONFIGURATION=debug software
But for normal rtl run, its throwing the same issue.

The hello program is the basic program I got from the package itself.
