Building error

[thesleort]

I have trouble building the kos-ports. I have previously been able to build them all without error (likely half a year ago when I played around with it last time), but now I get the following error:

Looking up the config.log does not help me much. config.log

I have tried to build the entire kos from the ground up again following https://dreamcast.wiki/Getting_Started_with_Dreamcast_development to no avail. In config.log it seems that it expects both some files but also something about a missing "-qversion" flag. This makes me wonder if I am configuring something incorrectly?

I am on Linux and usually disable objc and obj-c++ in config.mk in KOS.

Hey, sorry for the late response. Been a little puzzled on this one. Your config.log shows the following:

/home/troels/Documents/workspace/Dreamcast/toolchains/sh-elf/lib/gcc/sh-elf/13.2.0/../../../../sh-elf/bin/ld: /home/troels/Documents/workspace/Dreamcast/toolchains/kos/lib/dreamcast/libkallisti.a(thread.o): in function `thd_init':
/home/troels/Documents/workspace/Dreamcast/toolchains/kos/kernel/thread/thread.c:338:(.text.thd_init+0x158): undefined reference to `___builtin_set_thread_pointer'

Which has always been seen with an out-of-date toolchain which was built before we added support for TLS... But you say you just rebuilt the toolchains with the latest version of KOS checked out? No chance the toolchains were built like... 1 or 2 commits back but now you're on the latest? (TLS was just added).

Can I see your environ.sh as well?

By the way, if you need faster feedback or responses, feel free to drop by the #kos channel of the Simulant discord server, the official hangout of the DC homebrew scene and of KOS itself: https://discord.gg/ayMaWJP6w7

No worries at all! I have the biggest respect for all the work you and the others do on KallistiOS.

Yes, I just retried building it all again now (removed /home/troels/Documents/workspace/Dreamcast/toolchains/sh-elf) and I get the same error.

This is my config.mk which should be a modified copy of config.mk.stable.sample (removed objc, obj-c++, and changed the toolchains_base):

Thank you for the discord heads up.

So your environ.sh file is definitely old... It just got recently redone and should be based on this https://github.com/KallistiOS/KallistiOS/blob/master/doc/environ.sh.sample revised sample. That being said, I'm not sure that I'd really expect it to just not work or to be the root cause of the error, but I would definitely update to eliminate that as a variable...

The new environ base has preset flag combinations for things like fast math and certain optimization levels that we wanted to make developers more widely aware of, so they might be of interest to you.

No worries at all! I have the biggest respect for all the work you and the others do on KallistiOS.

We really appreciate it. Always excited to see anyone wanting to get into DC development, and we work really hard to make sure stuff like this just works for everyone on all platforms, but ... obviously failing on that one atm, haha.

After work today, I'll give your configurations a try and see if maybe I can reproduce this locally? Also going to ping some of the other guys.

[thesleort]

I tried the new environ.sh with my paths instead of the /opt directory. It still doesn't work.

I am following the guide in https://dreamcast.wiki/Getting_Started_with_Dreamcast_development and I have always been using this. Has something been changed or added to the way things should be built?

This is the updated environ.sh:

A little more digging with kos-ports I have found that it is able to build most of the kos-ports packages. If I removed the following from the kos-ports directory:

• expat
• freetype
• libopusplay
• libyaml
• opus
• opusfile

With all of these I get the same error as the OP in their respective config.log.

Without these I am, as said, able to compile the rest (the output after building them):

interesting, i think those kos-ports that are not building are the same (or similar) to the list of kos-ports that won't build with LTO enabled. But you don't seem to have it enabled in your environ.sh.

the guide at https://dreamcast.wiki/Getting_Started_with_Dreamcast_development is the guide I wrote and i keep it up to date with changes in KOS. just now i built the 13.2.0 toolchain + kos + kos-ports + all examples so I don't think this is a regression anywhere. hmm

If I remove the sh-elf directory, it says No such file or directory, so I am fairly certain that it uses the one that kos builds.

This is the spec dump of the sh-elf-gcc:

I am not sure what to look for, but to me it looks like the LTO that you mentioned has not been enabled as expected.

When I look at the config.log files, besides the error that @gyrovorbis mentions, I see the lines:

configure:4467: $? = 0
configure:4456: kos-cc -V >&5
sh-elf-gcc: error: unrecognized command-line option '-V'
sh-elf-gcc: fatal error: no input files
compilation terminated.
configure:4467: $? = 1
configure:4456: kos-cc -qversion >&5
sh-elf-gcc: error: unrecognized command-line option '-qversion'; did you mean '--version'?
sh-elf-gcc: fatal error: no input files

I am not sure if this is supposed to resolve itself, but to me it looks like the build script expects a different version of sh-elf-gcc thatn the one provided?

I think we can close this as being a local issue on my computer. I am able to compile everything using the exact same build setup on my laptop. I will return with more info if I find out why. Maybe it somehow uses some system libraries not present on my desktop.

OMG THANK THE LORD!!! I've been guilt-stricken by not being able to help you. I've set this stuff up on every platform for all kinds of people, helped troubleshoot all kinds of problems, and this was just... spooky. It does sound like a local issue, but if you ever find out what the specific cause was please let us know.

But more importantly CONGRATULATIONS! Make sure to check out the examples directory in KOS and let us know if you have any other questions!

I have been off for a while, since this is mostly hobby for me. However, recently pulled the latest kos which has the following in the config.mk.stable.sample:

# Floating point precision support (m4|m4-single|m4-single-only)
# Build support for various SH4 floating-point operation ABIs. KallistiOS only
# officially supports single-precision-only mode. Add m4 (double precision) or
# m4-single (single precision) to build experimental support for those ABIs.
precision_modes=m4-single-only
#precision_modes=m4,m4-single,m4-single-only

# Default floating point mode (m4|m4-single|m4-single-only)
# Choose the default floating point precision ABI used when GCC is invoked. This
# can be overridden by using passing -m4, -m4-single, or -m4-single-only to GCC.
# KallistiOS currently only supports m4-single-only, so that is the default.
default_precision=m4-single-only

I think this finally made it work and compile correctly on my desktop computer again. Of course it could be something else as well, but this at least somehow fixed it for me.

Awesome!!! Glad to hear that!
