[-- Attachment #1.1: Type: text/plain, Size: 1087 bytes --]

Hi there!
I would like to mainstream the PS2 newlib port. So far the PS2 has had
newlib ports for years, however, it was never intended to be merged into
the mainstream.

I'm now trying to port to the latest release 4.3.0, however, I'm suffering
some errors during the compilation process.

I have attached the changes that I have done so far.
Then I just rerun the command `autoreconf` using the proper autoconf and
automake versions

I execute `configure` with:

PROC_NR=$(getconf _NPROCESSORS_ONLN)

TARGET="mips64r5900el-ps2-elf"
TARGET_ALIAS="ee"

## Create and enter the toolchain/build directory
rm -rf "build-$TARGET"
mkdir "build-$TARGET"
cd "build-$TARGET"

## Configure the build.
CFLAGS_FOR_TARGET="-O2" ../configure \
--prefix="$PS2DEV/$TARGET_ALIAS" \
--target="$TARGET" \
--enable-newlib-retargetable-locking \
$TARG_XTRA_OPTS

## Compile and install.
make -j "$PROC_NR" all


And then it always fails with this error,

fatal error: opening dependency file libc/sys/ps2/.deps/crt0.Tpo: No such
file or directory

Could you help me to identify where the issue is?

Cheers.

Subject: [PATCH] Add specific r5900 machine and ps2 sys

- Do not use libgloss (we have ps2sdk)
- Use newlib reentrant syscalls
- Use posix functions
- Exclude OPENDIR functions
- Add -G0 in the newlib_cflags
- Fix time.h should have nanosleep defined
- Fix setjmp for R5900 CPU
- Add _POSIX_MONOTONIC_CLOCK to features
