I followed the guide in "Pico C SDK" document, Page 31, for building a GCC-14 toolchain for RISC-V. 10 hours of compilation later, 16GB of disk taken from me, I now have something which appears to be a GCC-14 RISC-V toolchain -Unfortunately, not quite -Same issue, unsurprisingly, when running 'cmake' to create the build files for an RP235X project.
I'll put my hands up to having followed the documented instructions to the letter, which ended up putting the built executables in '/opt/riscv/gcc14-rp2350-no-zcmp/bin' which isn't in my path so I copied them to '/usr/bin' which is and where all my other GCC compiler executables are.
That might be the issue, I don't know. I left the originals in place in case the copied executables contained hard links to where they think they are, were.
If anyone does know, knows what I need to do to fix things, I'd be very grateful because I really don't want to have to keep doing 10 hour builds to get it right.
Update : Seems there may be more files to copy than just the executables I have. I'll let you know if I get further.
Update : Seems I needed to copy at least 'cc1' -That got me further and I guess I can ignore this error as something like not having built 'libc' or something which might not matter for an RP235X build. At least we are beyond the 'cc1' error -The problem now seems more challenging -Specifically -So, all that effort for nothing ? I've built a RISC-V compiler which doesn't understand the architecture which the Pico SDK is expecting to use ?
I built it as per the documentation, used the specified './configure' which includes, reformatted for readability -That last looks close to what 'cmake' is looking for when the first two don't but I don't know enough about this stuff to know if it is or isn't.
I'm need of help and guidance again.
