[HOWTO] compile altcoin for windows on linux using mxe and mingw

[gjhiggins]

Can you help me with this error, thanks.

cd /mnt/coinm-source/src/leveldb && CC=i686-w64-mingw32.static-gcc CXX=i686-w64-                                                                             mingw32.static-g++ TARGET_OS=OS_WINDOWS_CROSSCOMPILE make OPT="-fno-keep-inline-                                                                             dllexport -pipe -D_FORTIFY_SOURCE=2 -O2" libleveldb.a libmemenv.a && i686-w64-mi                                                                             ngw32.static-ranlib /mnt/coinm-source/src/leveldb/libleveldb.a && i686-w64-mingw                                                                             32.static-ranlib /mnt/coinm-source/src/leveldb/libmemenv.a

There are two shell script files that need to be executable in order for the compilation process to succeed. If the dev has omitted to make them executable, the above error is seen:

share/genbuild.sh and src/leveldb/build_detect_platform

Make them both executable and try again.

FWIW: I won't be responding to any more “Can you help me?” PMs.

This exercise is public for a reason, so that knowledge is distributed - and from my perspective, so that others besides me can take turns in passing it on.

make[1]: Nothing to be done for 'libleveldb.a'.
make[1]: *** No rule to make target 'libmemenv.a'.  Stop.

I'v experienced this on more than one occasion. Sometimes it can be trivially solved by running make libmemenv.a in src/leveldb and sometimes not. If not then the only recourse is to try and deduce a fix by cross-referencing against the contents of leveldb and the top-level (qmake/autotools) build file of a close clonecousin.

Yeah, read upthread post : https://bitcointalk.org/index.php?topic=1080289.msg21247843#msg21247843 and, given that the basic nature of the question testifies to your innocence of the content of this thread, I strongly recommend you read all 7(!) pages.

Could you tell me how to solve this problem?

Not specifically, I'm afraid --- because the problem is local to your setup. Fairly obviously, it's a problem with the path to the MXE boost libs. Try reinstalling/recompiling the MXE suite - I have no idea whether that will help but it's a starting poiint.

in your link they think that person dont generated libleveldb.a and libmemenv.a files, but I have the files...

/mnt/coinm# ls src/leveldb | grep lib
libleveldb.a
libmemenv.a

You might need to summon a little more persistence, then you might progress a little faster.

For people arriving later with the same problem ... from the list of search results I gave:

If you haven't got the RANLIB binding as described here:

https://bitcointalk.org/index.php?topic=912667.msg10037005#msg10037005

then try with that.

Otherwise:

Other than that, you're on your own.

Have an idea how to fix this?

Hello everyone.

I've been compiling wallets for different Linux distros and for the Raspberry Pi and I thought I might give the Windows wallet a shot.

I followed the instructions on the first post exactly and everything worked perfectly until the compile.

I used Blackcoin as the example suggested.

The errors are as follows:

Code:

compile@compile-HP-Compaq-dc7700-Convertible-Minitower:/mnt/blackcoin$ sudo ./compile-blk.sh
./compile-blk.sh: 1: ./compile-blk.sh: #!/bin/bash: not found
./compile-blk.sh: 4: ./compile-blk.sh: i686-w64-mingw32.static-qmake-qt5: not found
make: Makefile.Release: No such file or directory
make: *** No rule to make target `Makefile.Release'.  Stop.
compile@compile-HP-Compaq-dc7700-Convertible-Minitower:/mnt/blackcoin$ 

Now here is the strange part. I put the path in correctly, and it shows up fine when I display environmental list in the terminal.

Any help would be appreciated.

Thanks.

Code:

compile@compile-HP-Compaq-dc7700-Convertible-Minitower:/mnt/blackcoin$ sudo ./compile-blk.sh
./compile-blk.sh: 1: ./compile-blk.sh: #!/bin/bash: not found
./compile-blk.sh: 4: ./compile-blk.sh: i686-w64-mingw32.static-qmake-qt5: not found
make: Makefile.Release: No such file or directory
make: *** No rule to make target `Makefile.Release'.  Stop.
compile@compile-HP-Compaq-dc7700-Convertible-Minitower:/mnt/blackcoin$ 

I have same error

Has anyone figured this out? It seems to recognize but complain about permissions when not run with sudo (which makes sense), but when ran with sudo with the correct path, it is still producing that error.

When I echo path, this is the output:

Code:

echo $PATH
/mnt/mxe/usr/bin:/mnt/mxe/usr/bin:/mnt/mxe/usr/bin:/mnt/mxe/usr/bin:/mnt/mxe/usr/bin:/home/ubuntu/bin:/home/ubuntu/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

Just guessing here because I can't reproduce the problem but perhaps default security has been tightened up, maybe sudo -E might help:

[gjhiggins]

i can compile for linux without a snag and all goes well if i do it the normal way ... but after following this "tut" 2 times with full reinstall i find that i get the very same issue each time

You're missing a trailing slash there ... there's no slash separator between the directory path and the executable file in /mnt/mxe/usr/i686-w64-mingw32.static/qt5/binlrelease.exe, the RCC errors are a direct consequence.

Then BDB_INCLUDE_PATH either was bound incorrectly or not at all (see references to BDB_* in bitcoin-qt.pro)

Hello,
Thanks for this great tutorial, it has been very useful to be able to start building the wallet for an altcoin.

I'm currently having this issue:

Code:

/home/zeus/Desktop/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lsecp256k1
collect2: error: ld returned 1 exit status

I saw that someone else had this issue here but he never got a response.
Can someone help me with this ? I guess it's my last step to be able to build the Windows wallet from Ubuntu.

Thank you for your fast reply, 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 :/

That's because the quoted instructions are for building Linux binaries of the secp256k1 library. Hint: if you're not using the compiler in /home/zeus/Desktop/mxe/usr/bin/i686-w64-mingw32.static-*, you ain't likely to be creating Windows-linkable binanies.

I haven't yet encountered a need to cross-compile secp256k1 libs but when I do, I'll be doing it inside the MXE cross-compilation environment. Others have adopted the tactic of simply compiling up the secp256k1 lib on Windows separately (or copying a Windows binary from somewhere else) and linking directly to those Windows libs.

Cheers

[GoldZeus]

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:

Thanks for the great tutorial.  So far I've been able to get through a few problems, but I'm stuck now with a Berkley DB linking problem.  I've recompiled it and tried a couple different versions.  I also removed all the Berkley DB files to see if I get a different error and it is the same, but everything looks correct when I check paths/names.  I'm not sure what I am doing wrong, but I'm getting these errors (small snippet since they are all the same undefined reference error):

Figured it out.  Solution for anyone else:
In my .pro file I was using:
BDB_INCLUDE_PATH=${MXE_LIB_PATH}
BDB_LIB_PATH=${MXE_LIB_PATH}
Because the install was putting the files there.  I'm not sure why that didn't work, but when I switched them to this it started working:
BDB_INCLUDE_PATH="/mnt/db-5.3.28/build_mxe"
BDB_LIB_PATH="/mnt/db-5.3.28/build_mxe"
