MinGW can't find libraries when compiling static build for altcoin wallet.

SGaist

Where are these files precisely located ?
Are you sure about their suffix ?

Madman66

Nowhere in the file system ...

"the libraries aren't being found by the build process, looks like you need to tend to your environment variable bindings."

... and I should check this example for the compiling bash - my system is Ubuntu 14.04 x64 by the way:

#!/bin/bash

# Vagrant Ubuntu 16.04 VM using non-Canonical ppas for MXE and Qt5.7:

Someone knows what has to be changed in my bash file to make it running:

@Madman66 said in MinGW can't find libraries when compiling static build for altcoin wallet.:

Well that's your problem then. Find out what the static boost libs are called on your file system and fix your build to use those. You will need to set BOOST_LIB_PATH properly. And make sure the names of the files match.

Madman66

According to https://github.com/mxe/mxe/issues/1942 I really have to fix the library path with -L
Would someone be so nice to explain me how to do that?

Might be a silly question, but are you sure you got boost built in the first place ?

Madman66

I build boost with
make MXE_TARGETS="i686-w64-mingw32.static" boost
in the mxe directory:
/mnt/mxe

in this order:
make MXE_TARGETS="i686-w64-mingw32.static" boost
make MXE_TARGETS="i686-w64-mingw32.static" gettext
make MXE_TARGETS="i686-w64-mingw32.static" qttools
make MXE_TARGETS="i686-w64-mingw32.static" qt
make MXE_TARGETS="i686-w64-mingw32.static" miniupnpc

I tried diffent sources for testing now, it always jumps off with -lboost ... so boost may actually be the problem. Any idea how I can fix that? See tail of latest try:

@Madman66 Add a -L/path/to/where/boost/libs/are to your project and it will find the libs using -lboost_system, etc.

Madman66

@ambershark thank you so much, but can you tell me where should I add

-L/path/to/where/boost/libs/are

excactly?

ambershark

@Madman66 It depends ... what build system are you using? autotools? qmake? cmake? command line?

Nevermind I looked above and see a .pro file so that's qmake.. Just add it to the LIBS line, i.e.

LIBS += -L/path/to/boost

It looks like it is trying to use the variable you set in your script:
LIBS += $$join(BOOST_LIB_PATH,,-L,). So you could always just set your BOOST_LIB_PATH properly. I already said all that in a previous post though. So I'm assuming that it didn't work properly. ;)
