Re: Creating MAT-file programs

Hi, I wrote a C/C++ program that convert a text file into .mat file.
I can compile on my Windows computer (that has Matlab installed, and
setting Microsoft Visual C++ to use the extern libraries). But I
also want to use this program on Linux computers.

According to:
<http://www.mathworks.com/support/solutions/data/1-16AEN.html?solution=1-16AEN>
I can do that on Linux, all I have to do is download the MAT library
files. And tell the compiler/linker where to find the files.

However, when I couldn't get the program to link, it keeps giving me
the following error:
/usr/bin/ld: skipping incompatible ...../v6/libmat.so when searching
for -lmat
So, that means it find the .so files, but the linker believes they
are incompatible and ignores them.

I tried to download different version, but they all give me the same
error. The following are the location I downloaded the files:
<http://www.mathworks.com/support/solutions/files/s8757/v6/lib/glnx86/>
<http://www.mathworks.com/support/solutions/files/s8757/libc6/>
<http://www.mathworks.com/support/solutions/files/s8757/lib/lnx86/>

Could it be because my Linux machines are Athlon64 computers, with
x86_64 OS?

Yes.

Do I need special version of those libraries? If so, where can I get
them.

Maybe. Try compiling with the -m32 switch, to compile in 32-bit
application mode. You'll lose the benefits of 64-bit for this
application, but who cares? This way the library you downloaded might
work...

If not, you will need the 64-bit libraries.
