While run the RISCV-PK we are getting the errors like Command: ../configure --prefix=/PATH/RISCV/riscv64-unknown-elf --host=riscv64-unknown-elf

Can you verify your install of riscv64-unknown-elf-gcc worked?

Hi sbeamer,

How can i verify the riscv64-unknown-elf-gcc worked or not? In installation bin path we have riscv64-unknown-elf-gcc riscv64-unknown-elf-gprof riscv64-unknown-elf-ranlib spike-dasm fesvr-eth riscv64-unknown-elf-c++ riscv64-unknown-elf-gcc-4.9.2 riscv64-unknown-elf-ld riscv64-unknown-elf-readelf termios-xspike fesvr-rs232 riscv64-unknown-elf-c++filt riscv64-unknown-elf-gcc-ar riscv64-unknown-elf-ld.bfd riscv64-unknown-elf-size xspike fesvr-zedboard riscv64-unknown-elf-cpp riscv64-unknown-elf-gcc-nm riscv64-unknown-elf-nm riscv64-unknown-elf-strings riscv64-unknown-elf-addr2line riscv64-unknown-elf-elfedit riscv64-unknown-elf-gcc-ranlib riscv64-unknown-elf-objcopy riscv64-unknown-elf-strip riscv64-unknown-elf-ar riscv64-unknown-elf-g++ riscv64-unknown-elf-gcov riscv64-unknown-elf-objdump spike.

Write a simple hello world program and attempt to compile it with riscv64-unknown-elf-gcc. If the compiler errors out, you will know you need to redo your riscv-gcc install.

Based on the info you posted, it appears autoconf doesn't have access to the same PATH.

Hi, Actually the issue is with installing RISCV PK. After downloading the dump, i used the following Commamd,
CC=riscv64-unknown-elf-gcc ../configure --prefix=$path/riscv64-unknown-elf --host=riscv64-unknown-elf but it says C compiler cannot create executables..!!! How can i solve this problem..??

checking build system type... x86_64-unknown-linux-gnu checking host system type... riscv64-unknown-elf checking for riscv64-unknown-elf-gcc... riscv64-unknown-elf-gcc checking whether the C compiler works... no configure: error: in /Downloads/RISCV/Toolchain/riscv-pk/build': configure: error: C compiler cannot create executables

[sbeamer]

Yes, I understand the concern is over riscv-pk. Because autoconf complains the C compiler can't create executables (it was able to find riscv64-unknown-elf-gcc), I recommend you first verify that riscv64-unknown-elf-gcc was installed correctly. It is possible that the build process can complete, but the resulting binaries will not run (often due to a linking issue). I recommend attempting to compile a hello world program rather than running the compiler with no arguments to test if it is installed correctly.

[santhoshvlsi]

1. Compile the Hello world program and we are getting the executable file HHH riscv64-unknown-elf-gcc -o HHH hello.c.
2. Generated the Dump file.The command is riscv64-unknown-elf-objdump --disassemble-all HHH > d_hello.dump.
3. Generated the Hexadecimal file. elf2hex 16 16384 HHH > elfhex_hello.

While simulate the HHH file in spike simulator(2 ways)

1. "spike pk HHH" terminate called after throwing an instance of 'std::runtime_error' what(): could not open pk
2. "spike HHH" or "spike -d HHH" then we are geting the display in terminal core 0: exception trap_illegal_instruction, epc 0x0000000000000000 core 0: 0x0000000000000000 (0x00001000) unknown core 0: exception trap_illegal_instruction, epc 0x0000000000000000

How can i solve this problem..??

[sbeamer]

Since you are able to get HHH, it appears your riscv64-unknown-elf-gcc may be working. I would try building riscv-pk again and examining config.log if autoconf fails again. Your trace from above had the error "checking whether the C compiler works... no" which means autoconf was able to find riscv64-unknown-elf-gcc but it did not pass autoconf's sanity checks. Hopefully config.log will contain more information you can use to debug your installation.

[santhoshvlsi]

Run these command CC=riscv64-unknown-elf-gcc ../configure --prefix=/home/riscv_installation/riscv64-unknown-elf-gcc --host=riscv After theat In bulid folder we are geting the config.log file.

This is the log file.

This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by RISC-V Proxy Kernel configure ?, which was generated by GNU Autoconf 2.69. Invocation command line was $ ../configure --prefix=/home/riscv_installation/riscv64-unknown-elf-gcc --host=riscv

I would verify that your riscv64-unknown-elf-gcc can compile a hello world and you get a binary out.

Looking at the log you posted, riscv64-unknown-elf-gcc can't find cc1. Is it possible you moved your riscv compiler after building it? It is best to build it with its final target directory given by --prefix.

I have the same problem, has anyone solved it?
