@helpPls What's the whole error message? That just looks like the first line of one.

This isn't the whole thing...

@helpPls Did you do what @aha_1980 suggested?

[helpPls]

@jsulm

You mean, change / to ? Um...So comments are \ now? That didn't seem like a solution so I didn't try it. Should I?

[jsulm]

@helpPls You should use / instead of \ in paths:

INCLUDEPATH += C:/armadillo-9.400.3/include

"So comments are \ now?" - which comments do you mean? \ is an escape character and at the end of a line in pro files it means that the line continues in the next line:

LIBS += -LC:/Users/Phil/Desktop/TITO/Armadillo/armadillo-9.400.3/examples/lib_win64 \
-llapack_win64_MT \
-lblas_win64_MT

Hi..so my pro file looks like this now. The new error message is at the bottom.

TEMPLATE = app
CONFIG += console c++11
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += /
main.cpp

#INCLUDEPATH += C:/armadillo-9.400.3/include

#LIBS += /

-LC:/armadillo-9.400.3/lib_win64/

-llibblas32 /

-lliblapack32

INCLUDEPATH += C:/Users/Phil/Desktop/TITO/Armadillo/armadillo-9.400.3/include

LIBS +=
-LC:/Users/Phil/Desktop/TITO/Armadillo/armadillo-9.400.3/examples/lib_win64
-llapack_win64_MT

Hi @helpPls

please adopt your pro file to what @jsulm suggested.

Further:

1. C:/Users/Phil/Desktop/TITO/Armadillo/armadillo-9.400.3/examples/lib_win64 - is it really examples/lib?

2. You are using a MinGW-32-Bit Kit, but give the linker a lib_win64 directory - is that correct?

[helpPls]

@aha_1980

Hi..thank you for trying to help me. I adopted @jsulm's pro file and get the exact same errors. For 1., yes, that's where my files are. For 2., I tried it with MinGW-64 and it doesn't matter. It's all the same. Extremely frustrating. Wow, I just don't know what else to do.

[jsulm]

@helpPls Please post you current pro file and please use the </> tags to encode it as code.
You can also check generated Makefile.
And post the complete compiler/linker output.

[aha_1980]

Hi @helpPls,

and just to add to @jsulm, which files are actually located in the lib_win64 directory? Under Windows, you have linker include files for MSVC and MinGW compiler, and they are not compatible. Also, as already said, 32-bit and 64-bit libraries are also impossible to mix.
