Ethereum build error - /usr/bin/ld.gold fatal error - invalid argument

[bobsummerwill]

When building Ethereum C++ under Bash-for-Windows, both myself and @juanfranblanco are encountering the same error in the gold linker:

This works on "real" Ubuntu Trusty and does not work on Bash-for-Windows, presumably due to some issue in one or more of the Linux syscalls.

To replicate:

• Install these packages
• Follow these git clone, cmake and make steps (use develop branch)

[juanfranblanco]

Note: Do not build the Gui, check the cake lists. Txt

[bobsummerwill]

^ Sorry - I have literally no idea what you mean above, @juanfranblanco!

[juanfranblanco]

Stupid autocorrect.

I meant do not build the GUI, as it has dependencies with QT which cannot be installed. Look at the flag on the cmakelists.txt. This does not solve the issue, this is the step required to get to the issue.

[bobsummerwill]

Yum ... cake lists :-) Right - gotcha.

So maybe cmake .. && make eth, for example?

[juanfranblanco]

I personally removed the Gui parts from Cmakelists.txt (or use cmake .. -DGUI=0) as I need everything. Cmake will fail as the QT dependencies could not be installed (at least in mine, but I assume this is by design for the bash). This is the reason apt-get install cpp-ethereum does not work as it includes mix and alethzero.

@juanfranblanco I am just downloading Insider Build 14332, and will try again.

I am on 14238.1000 right now (which was an update from when I first tried this - looks like it is this one from 5 days ago - http://www.windowscentral.com/windows-10-build-14328-pc-and-mobile-here), but that is getting numerous errors like this when trying to rm -rf my git clone directory for webthree-umbrella:

rm: cannot remove "x": Input/output error

[bobsummerwill]

Looks like the one which I am downloading only came out yesterday:

[bobsummerwill]

Hmm. Same input/output error in 14332, so I'm having to do a new git clone as a co-directory and try that. Cannot delete the old one!

[bobsummerwill]

So it's all a bit knackered. I will go through all my apt-get steps again and see where I can get to.

[juanfranblanco]

you got further than me this time... i cannot install dependencies (time for bed)

[bobsummerwill]

Well, I think I probably need to do that too, given my silly error message where it doesn't even seem to see the C compiler. I wonder whether the sub-system needs nuking and rebuilding? My rm -rf webthree-umbrella doesn't even work.

I will also carry this on tomorrow, @juanfranblanco!

[bobsummerwill]

Woohoo! Got a binary today, @juanfranblanco :-)

It crashes, but that is another story.

That was with https://github.com/bobsummerwill/cpp-ethereum/tree/merge_repos, and running the setup.sh in there, plus a tweak to disable tests in jsonrpccpp, which I will commit shortly.

[bobsummerwill]

Looks like the crash is an exact dupe of #308.

getifaddrs() doesn't work. I'll add our details there.
