I'm trying to use MinGW gfortran with MATLAB R2019a on Windows 10 by writing a mexopts XML file based on existing XML files. I have cygwin installed with MinGW gcc, and I've been able to run mex -setup referencing the XML file successfully. When I try to compile the timestwo.F file to test the setup (using mex -R2018a timestwo.F90), I get a bunch of errors:

It seems like the mex-specific types like mwPointer defined in fintrf.h aren't being defined, even though I've included its location. Why are these types not recognized?
I have a set of mex files that use Armadillo and BLAS/LAPACK that I can compile on Windows with the following:
srcFolder = pwd;
outputFolder = 'some/other/folder/';
blaslib = fullfile(matlabroot, 'extern', 'lib', computer('arch'), 'microsoft', 'libmwblas.lib');
lapacklib = fullfile(matlabroot, 'extern', 'lib', computer('arch'), 'microsoft', 'libmwlapack.lib');
flags = {'-O', '-outdir', outputFolder};
mex(flags{:}, fullfile(srcFolder, 'filter_uni.cpp'), blaslib, lapacklib);
When I attempt this on linux, the linker appears to not find the .so files I provide:
blaslib = fullfile(matlabroot, 'bin', computer('arch'), 'libmwblas.so')
lapacklib = fullfile(matlabroot, 'bin', computer('arch'), 'libmwlapack.so')
mex(flags{:}, fullfile(srcFolder, 'filter_uni.cpp'), blaslib, lapacklib, '-v');
Partial output:

Is there a different way of specifying these .so files that should be used on linux?

How to compile perl with DEBUG_LEAKING_SCALARS?
The doc has error. To compile perl with this option on you should use next command:
perlbrew install perl-5.24.1 -DDEBUGGING -Accflags=-DDEBUG_LEAKING_SCALARS -j9 --as perl-debug-5.24.1
I have found this info from this commit
UPD
DOC was fixed at commit #b49862865 by David Mitchell. Thanks
If I understand perldoc perlop correctly, this operation should something undefined:
The result of overflowing the range of the integers is undefined because it is undefined also in C. In other words, using 32-bit integers, 1 << 32 is undefined. Shifting by a negative number of bits is also undefined.
I'm noticing two things on my setup that I cannot explain:
1 << -1 returns 9223372036854775808 without bigint or integer pragmas (returns NaN when they are active).
> perl -le "print 1<<-1"
9223372036854775808
1 << -1 returns true when tested with defined, regardless of whether or not the bigint or integer pragmas are in effect
> perl -le "print 'yes' if defined(1<<-1)"
yes
> perl -le "use integer; print 'yes' if defined(1<<-1)"
yes
> perl -le "use bigint; print 'yes' if defined(1<<-1)"
yes
Details of my setup:

When they say undefined, they are referring to undefined behaviour, not the value undef.
If the result of an operation is undefined behaviour, it means that anything could happen -- you could get a surprising result, a different result on different platforms, a different result each time you do the same thing, or 3-foot tall snails could come out of your computer and start speaking Swahili (though that last one is rather uncommon in practice).
In other words, because it's explicitly documented as undefined behaviour, anything perl does is technically correct -- which means you can't rely on it to do anything useful.
The number 9223372036854775808 is equal to 2^63. Given a 64-bit unsigned integer initialized to 1, rotating it by one bit to the right gives this result. This is probably what's happening: << -1 is being interpreted as a rotate right by one.
But since shifting by negative values is undefined, this is not something that can be depended on. The coincidence is worth noting, however.
