qemu e31 demo project build failing

[fsaud]

I am trying to build the qemu-sifive-e31-hello template, but it is failing.

Following is the build log

23:06:35 **** Build of configuration debug for project qemu-sifive-e31-hello **** make all CONFIGURATION=debug cd /c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/build/debug/ && \ CFLAGS="-march=rv32imac -mabi=ilp32 -mcmodel=medlow -ffunction-sections -fdata-sections -I/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/install/include --specs=nano.specs -O0 -g" \ /c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/freedom-metal/configure \ --host=riscv64-unknown-elf \ --prefix=/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/install \ --libdir=/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/install/lib/debug \ --disable-maintainer-mode \ --with-preconfigured \ --with-machine-name= \ --with-machine-header=/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/metal.h \ --with-machine-inline=/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/metal-inline.h \ --with-platform-header=/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/metal-platform.h \ --with-machine-ldscript=/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/metal.default.lds \ --with-builtin-libgloss checking for a BSD-compatible install... /c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/freedom-metal/install-sh -c checking whether build environment is sane... yes checking for riscv64-unknown-elf-strip... riscv64-unknown-elf-strip checking for a thread-safe mkdir -p... /usr/bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... no checking whether to enable maintainer-specific portions of Makefiles... no checking for riscv64-unknown-elf-gcc... riscv64-unknown-elf-gcc checking whether the C compiler works... no configure: error: in /c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/build/debug': configure: error: C compiler cannot create executables See `config.log' for more details make: *** [Makefile:270: /c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/build/debug/Makefile] Error 77

Kindly resolve the issue as it is, as far as I understand, related to tools

FYI This is a freedom-e-sdk problem not a freedom-u-sdk problem. They are maintained by different people and do different things.

The error appears to be in the file /c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/build/debug/config.log which you did not attach so there isn't enough info here to tell what went wrong.

Thanks Jim, I am just starting with riscv and setting the things up, trying to execute the demos but unfortunately it is not building. I would be very much thankful to you if you help in this matter

The error appears to be: configure:2921: riscv64-unknown-elf-gcc -march=rv32imac -mabi=ilp32 -mcmodel=medlow -ffunction-sections -fdata-sections -I/c/Users/fsaud/wsFreedomStudio/qemu-sifive-e31-hello/bsp/install/include --specs=nano.specs -O0 -g conftest.c >&5 riscv64-unknown-elf-gcc.exe: error: CreateProcess: No such file or directory

I think CreateProcess is a windows system call. Maybe it can't find the cc1 binary? Or is it the gcc binary that it can't find? The error messge isn't very helpful. freedom-u-sdk unfortunately is for our Unix support. I don't have access to a windows machine, and don't know much about how the windows support works. It might be a PATH problem. What happens if you run riscv64-unknown-elf-gcc.exe directly? Does that work? If not, then you probably need to modify your PATH to add the toolchain install directory.
