building master on macOS X

[michaeljclark]

I've successfully built master on Linux however I am having trouble building master on macOS X.

Here is my stamps dir:

ls stamps/
build-binutils-newlib

It's failing on the second step: build-gcc-newlib

mclark@monty:/Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build$ make
rm -rf stamps/build-gcc-newlib build-gcc-newlib
mkdir build-gcc-newlib
cd build-gcc-newlib && /Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/configure \
        --target=riscv64-unknown-elf \
        --prefix=/opt/riscv/toolchain-master \
        --disable-shared \
        --disable-threads \
        --enable-tls \
        --enable-languages=c,c++ \
        --with-newlib \
        --disable-libmudflap \
        --disable-libssp \
        --disable-libquadmath \
        --disable-libgomp \
        --disable-nls \
        --disable-soft-float \
        --disable-multilib \

/bin/sh: /Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/configure: No such file or directory
make: *** [stamps/build-gcc-newlib] Error 127

I noticed that the subdirectory exists. It's almost as if one of the copy commands is working differently on macOS X has there is an additional subdirectory newlib-gcc/newlib containing the source instead of newlib-gcc which is what the Makefile is expecting.

mclark@monty:/Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build$ ls /Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/newlib/configure
/Volumes/riscv-toolchain-build-master/riscv-tools/riscv-gnu-toolchain/build/src/newlib-gcc/newlib/configure

Any ideas on how to troubleshoot?

I really only need binutils for the latest CSRs so I could perhaps overlay the binutils on top of an older gcc...

[michaeljclark]

OK. I haven't solved the build issue but I am okay for now. I made a copy of my earlier toolchain and copied over the binutils that successfully built from master, so now I have access to the latest CSRs. on macOS X. gcc seems happy with the new CSRs. I have newer gas. Last build is older than I thought. I called the combined toolchain frank 😄 .

BTW just a note - I first tried using hex constants for the newer CSRs but it didn't work. In any case, it is working for me now.

#define MIDELEG 0x303
#define MEDELEG 0x302
#define HIDELEG 0x203
#define HEDELEG 0x202

// send S-mode interrupts and most exceptions straight to S-mode
static void delegate_traps()
{
  uintptr_t interrupts = MIP_SSIP | MIP_STIP | MIP_SEIP;
  uintptr_t exceptions =
    (1U << CAUSE_MISALIGNED_FETCH) |
    (1U << CAUSE_FAULT_FETCH) |
    (1U << CAUSE_BREAKPOINT) |
    (1U << CAUSE_FAULT_LOAD) |
    (1U << CAUSE_FAULT_STORE) |
    (1U << CAUSE_BREAKPOINT) |
    (1U << CAUSE_USER_ECALL);

  write_csr(MIDELEG, interrupts);
  write_csr(HIDELEG, interrupts);
  write_csr(MEDELEG, exceptions);
  write_csr(HEDELEG, exceptions);
  assert(read_csr(MIDELEG) == interrupts);
  assert(read_csr(HIDELEG) == interrupts);
  assert(read_csr(MEDELEG) == exceptions);
  assert(read_csr(HEDELEG) == exceptions);
}

It may be that a submodule is out of sync after a pull e.g. riscv-gnu-toolchain/riscv-newlib

I'll try building a clean checkout of riscv-tools:master on macos and will update this issue...

[palmer-dabbelt]

We just built on OSX, and since you didn't update I'm assuming it's user error :). Feel free to re-open it I screwed up.

[michaeljclark]

No worries. I'll try a build on macOS with a clean checkout. I currently still have gcc-6.1.0 on my mac :) I've found vintage compilers are useful for comparisons...

It's working fine now. I built from the v20170818 tag. Thanks.
