MinGW-W64 linker skipping incompatible files when searching for third-party static libraries

Question

MinGW-W64 linker skipping incompatible files when searching for third-party static libraries

I'm on Windows 7 64-bit, and I'm compiling with g++ from MinGW-W64.

I'm trying to compile an application that I wrote on a Unix computer. I'm running into problems, however, when I try to link against certain third-party lib<name>.lib files. Specifically, I need to link to ROOT libraries. The linker spits out errors such as

C:/Users/jroth/Data/nest3/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/5.1.0/../../
../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:/root/root_v5.34.28

../../x86_64-w64-mingw32/bin/ld.exe: cannot find -llibGui

I'm completely at a loss as to what to do. I've tried re-installing MinGW-W64 several times in various different configurations, fiddling with my -L and -l tags, renaming the libraries, writing out their full paths explicitely, etc. I can get the thing to yield different errors, but it always gives errors.

I'm compiling with the batch file below.

@echo off

set g++=C:\Users\jroth\Data\nest3\mingw64\bin\g++

set rootconfig=-pthread -m64 -IC:/root/root_v5.34.28/include -LC:/root/root_v5.34.28/lib -llibGui -llibCore -llibCint -llibRIO -llibNet -llibHist -llibGraf -llibGraf3D -llibGpad -llibTree -llibRint -llibPostscript -llibMatrix -llibPhysics -llibMathCore -llibThread -pthread -lm -ldl

%g++% -std=c++0x -Wall -o online_monitor.exe main.cpp external_input.o periodic_dinger.o flagger.o monitor.o %rootconfig%

The result of running this is

BFD: C:\root\root_v5.34.28\lib\libGui.lib(libGui.dll): Recognised but unhandled
machine type (0x14c) in Import Library Format archive

I actually got things like this a whole bunch of times, and I eventually press Ctrl-C, but anyway . . . this makes me think that the libraries are 32-bit. I think that this might be a problem, but I'm not sure how to fix it. Using the -m32 option on g++ makes it reject all of the standard libraries for C++.

I think that that's about all I have . . . I would be very willing to provide more info if it would be helpful, and a great many thanks in advance for your help on this.

Continuing Fangqing Du's answer:

If your active build system does not support MINGW32 builds, you need to install it, e.g. from Mingw32 @ SourceForge. You probably want to keep the 64-Bit build system as default. Then you need to tell the build configuration to support the mingw32-runtime:

Define a build variable ${MINGW32_HOME}, such that ${MINGW32_HOME}\bin contains the compiler binaries
Precede the PATH variable by ´${MINGW32_HOME}\bin;´
Precede header include path list by ´${MINGW32_HOME}\include;´

This worked for me in Eclipse CDT; other projects and configurations are not touched.

From the message dumped from objdump.exe, the lib you need to link with is 32-bit, and the *.o files generated from the gcc (x64) is 64-bit, so is incompatible. I think you need to install MinGW 32-bit version.

The problem was likely that the libraries were compiled with VC++, so they apparently aren't compatible with GCC. They link fine using Microsoft's link.exe.
