Hey @gjhiggins thanks for the reply.
How do you link to that directory?

Take a look at xtrabytes examples, compile-win.sh which shows how to cross-compile the leveldb/memenv libraries https://github.com/borzalom/XtraBYtes/blob/master/compile-win.sh#L12 and xtrabytes-qt.pro which shows how to bind the environment variables to pick up the newly cross-compiled libraries: https://github.com/borzalom/XtraBYtes/blob/master/xtrabytes-qt.pro#L113

Just follow the examples, copynpasta, swapping out leveldb for secp256k1, (dunno if you need to add secp256k1 files to SOURCES and HEADERS, depends on how the interface to the library is implemented in your specific codebase). Begin edit-compile-debug cycle, hope it terminates successfully.

Cheers

Graham

Can you be more specific? I've tried working around with those files but i keep getting the same error.
Thanks

Hey @gjhiggins thanks for the reply.
How do you link to that directory?

I did download the option others posted here from Windows (pre-built) and tried to copy it pretty much everywhere @_@.

I tried to copy the content of the folder secp256k1 directly to /home/zeus/Desktop/mxe/usr/i686-w64-mingw32.static and also the folder itself.
And I tried to copy the contents of the same folder to /home/zeus/Desktop/mxe/usr/i686-w64-mingw32.static/bin (as this we add it to on the PATH= as per the tutorial) and the folder itself.

I also tried to merge the contents of /home/zeus/Desktop/AltCoin/src/secp256k1 with the ones from Windows.

None of the options worked.

Am I missing something on my file /home/zeus/Desktop/AltCoin/compile-win.sh?

Code:

its needs to be in you /mnt/mxe/usr/lib/gcc/i686-w64-mingw32.static/5.4.0 folder that worked past my errors now im getting this

I try to compile the secp256k1 with ming and i get this

maybe should try to compile on windows like other have done? this coin has older version of the secp256k1 so i cannot use the binary that are on here it seems
didnt know if error was only refering to the test.o or the libsecp256k1.la
any help would be awesome great guide btw have successfully done other coins

Hey guys, if ya'll haven't found the solution to this yet, here's my code to cross compile Stipend from Ubuntu to Windows, let me know if this helps!
