Cannot compile on Alpine or OpenSUSE

[jobukkit]

Am I missing a package, or is Construct incompatible with Alpine?

configure:24142: error: in `/home/construct/Downloads/construct':
configure:24144: error: cannot compute sizeof (char16_t)
See `config.log' for more details

Relevant part of config.log (I think?):

configure:24133: checking size of char16_t
configure:24138: g++ -std=gnu++17 -o conftest -mtune=native -march=native -mno-sse4a -fno-threadsafe-statics -fvisibility-inlines-hid>

Am I missing a package,

It seems that the issue is with the linker and not char16_t. I think you might be missing the gold linker package. Check for ld.gold.

[jobukkit]

I installed binutils-gold but that didn't fix it.

[jevolk]

The above log doesn't show any symbol or compilation error for char16_t, but instead gives an error for --rosegment to ld. I recognized this a gold feature. If you have installed gold now could you perhaps try to clear the config cache (i.e git clean -f -x -d) and re-run configure and post a new log?

If the log is exactly the same, the issue appears to be gold not being found and used. AFAICT ./configure searches for ld.gold and if the Alpine package installs it under a name other than ld.gold please let me know.

On OpenSUSE Leap 15.2 I got

checking for library containing __dynamic_cast... no
configure: error: Please install libstdc++ on this system.

even though libstdc++6 was installed.

On Ubuntu 20.04, ./configure works but during make install I got

What am I doing wrong 😣

Ubuntu 20.04

This one is easy, you'll just need more RAM to compile some of these units with complex grammars. It should be sufficient with 2 GiB per unit (per core) but in certain circumstances that's close to the edge and parts of the system might swap; so slightly more than 2 GiB may be required for a system which compiles (swap included).

OpenSUSE Leap 15.2

This one I'm not sure...

Thanks, I added a 2 GB large swap file, and now I have it working on Ubuntu! Keeping this issue open for Alpine and OpenSUSE problems.

On Alpine, at least, if you rename ld to something else and then symlink ld.gold to ld you can get around the issue.

mv /usr/bin/ld /usr/bin/ld.bak ln -s /usr/bin/ld.gold /usr/bin/ld mv /usr/x86_64-alpine-linux-musl/bin/ld /usr/x86_64-alpine-linux-musl/bin/ld.bak ln -s /usr/x86_64-alpine-linux-musl/bin/ld.gold /usr/x86_64-alpine-linux-musl/bin/ld

But it looks like it doesn't like musl because I get compile errors with both gcc and clang when trying to build with Alpine.

You can paste the error here if it fits, otherwise feel free to pastebin the full build log.
