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

Madman66

Sorry for the newbie question. Just at the very end compiling jumps out with:

/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lsecp256k1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_system-mgw53-mt-s-1_65_1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_filesystem-mgw53-mt-s-1_65_1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_program_options-mgw53-mt-s-1_65_1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_chrono-mgw53-mt-s-1_65_1
collect2: error: ld returned 1 exit status
make: *** [release/zaca-qt.exe] Error 1

I guess the solution is very simple and I really appeciate any help!!! Thanks in advance!

I compile the src with:

#!/bin/bash
MXE_INCLUDE_PATH=/mnt/mxe/usr/i686-w64-mingw32.static/include
MXE_LIB_PATH=/mnt/mxe/usr/i686-w64-mingw32.static/lib

Hi and welcome to devnet,

You likely need to add a LIBS += -L$${BOOST_LIB_PATH} statement in zaca.pro or at least where you are have the -lboost_system* statements.

Madman66

adding to zaca.pro:
LIBS += -lboost_system$$BOOST_LIB_SUFFIX -lboost_filesystem$$BOOST_LIB_SUFFIX -lboost_program_options$$BOOST_LIB_SUFFIX -lboost_thread$$BOOST_THREAD_LIB_SUFFIX -L$${BOOST_LIB_PATH}
windows:LIBS += -lboost_chrono$$BOOST_LIB_SUFFIX

results in:
make: i686-w64-mingw32.static-g++: Command not found
make: *** [release/zaca-qt.exe] Error 127

complete lboost section in .pro file is:

# Set libraries and includes at end, to use platform-defined defaults if not overridden
INCLUDEPATH += $$BOOST_INCLUDE_PATH $$BDB_INCLUDE_PATH $$OPENSSL_INCLUDE_PATH $$QRENCODE_INCLUDE_PATH
LIBS += $$join(BOOST_LIB_PATH,,-L,) $$join(BDB_LIB_PATH,,-L,) $$join(OPENSSL_LIB_PATH,,-L,) $$join(QRENCODE_LIB_PATH,,-L,)
LIBS += -lssl -lcrypto -ldb_cxx$$BDB_LIB_SUFFIX

# -lgdi32 has to happen after -lcrypto (see  #681)
windows:LIBS += -lws2_32 -lshlwapi -lmswsock -lole32 -loleaut32 -luuid -lgdi32
!windows: {
    LIBS += -lgmp
} else {

}

windows:LIBS += -lboost_chrono$$BOOST_LIB_SUFFIX

contains(RELEASE, 1) {
    !windows:!macx {
        # Linux: turn dynamic linking back on for c/c++ runtime libraries
        LIBS += -Wl,-Bdynamic
    }
}

!windows:!macx {
    DEFINES += LINUX
    LIBS += -lrt -ldl
}

system($$QMAKE_LRELEASE -silent $$_PRO_FILE_)

I just managed to fix the secp256k1 install, now this error is gone, but the others are still there:

/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_system-mgw53-mt-s-1_65_1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_filesystem-mgw53-mt-s-1_65_1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_program_options-mgw53-mt-s-1_65_1
/mnt/mxe/usr/bin/i686-w64-mingw32.static-ld: cannot find -lboost_chrono-mgw53-mt-s-1_65_1
collect2: error: ld returned 1 exit status
make: *** [release/zaca-qt.exe] Error 1

I would really appreciate any help with that!! Thanks!!

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

Madman66

Nowhere in the file system ...

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

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

Nowhere in the file system ...

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. ;)
