Topic: [HOWTO] compile altcoin for windows on linux using mxe and mingw - page 6. (Read 49055 times)

Could you provide detail step to downgrade Openssl version 1 ?

Download the version from openssl.org, go down one version at a time from the one you're using.

Here's a build script you can modify accordingly to your system setup and work from there...

I tried that, but I don't think I was successful, how does one do that?

Edit: and which version does one downgrade to?

downgrade the libssl version you're using

How do we fix thee BIGNUM error, I think that could help a lot.

Final stage to compile it. it has error below.

Any solution ?

Can we add QR code on QT wallet  ?

Regards

I already tried to configure and do the make install before and it didn't change anything. I tested it all again, including the ldconfig (just to make sure), but this option didn't solve the issue

Try reinstalling/recompiling the MXE suite - I have no idea whether that will help but it's a starting poiint.

Thank you,

I changed
    to
    and got past
    
There's other errors now so I'm not sure if it's the proper fix but it might help some people.

I figured out


Turns out this is from developers deleting things from the repo to make your life harder. With this issue, you are likely missing the share, contrib, and doc folders.

This one is still an issue for me:

@agricoin which coin you compiling ?

Any Idea how to fix this?

Hello everyone,

I am getting an error saying


Everything seems fine, it compiles for couple minutes, then gives this error. Couldn't solve.

as promised I managed to get an older fork to work
I replaced

cd /mnt
git clone https://github.com/mxe/mxe.git

with

cd /mnt
git clone https://github.com/abhisit/mxe.git

it works for my needs. maybe somebody else will find a better version

they appear to have updated MXE and it's causing the bignum errors. think it's the openssl version. I'll post more when I figure it out
