make.m problem in win10 & MinGW64 compiler about libsvm HOT 73 OPEN

Just open the Make.m file and find all "CFLAGS". Then replace them with "COMPFLAGS" and run the file. Hope it works for you.

from libsvm.

I am on win10 x64 also and I also use r2018a and MinGW64. I replaced all the CFLAGS by COMPFLAGS. But it doesn't work.... Please save me!!!

It works now! I am toooooo stupid. I just restart the Matlab and then it works!
Many thanks!!!

from libsvm.

That's really help!!! How you figured this out?

from libsvm.

Thanks very much!!
It works.
Thank God, it made me crazy!

from libsvm.

Thank you very much!!!!!

Thank you very very much!
I have solved this problem for five days!

Thank you very much!! That really helps!

Is there anyone buid right on win 10 use vs 2015 community?
I do it, and got "math.h no such file or dirctory". I change to makefile.win add include dir in CFLAGS, it's no use.
then I use vs 12, alse add include dir in CFLAGS, got "size_t redefine".
what's wrong?

I love this guy.

from libsvm.

Tahnk you very much!. It also worked for me.

Zomg thank you so much!!!1 It works now.

from libsvm.

Thanks a ton...
God bless.... I spend entire day fixing it out.. but this small modification works like magic...
I wonder how u got this.... thanks again

from libsvm.

Thank you very much!! Although I've know idea what was happend there after replacing all the CFLAGS with COMPFLAGS. It really worked!!!!

from libsvm.

Thanks!!!

Thank you so much !!! This really worked like magic!

make.m is not showing any error anymore but still, it is not adding the library (libsvm) in MATLAB 2014b.

from libsvm.

Thanks, that works great!

i am using matlab R2017a and using libsvm.when i try to run the make.m file "Building with 'MinGW64 Compiler (C)'.
Error: C:\Users\PANKAJ\Desktop\libsvm-3.22\libsvm-3.22\matlab\make.m failed (line 13)
gcc: error: -fexceptions: No such file or directory" error is shown ??compflag solution isn't working.please guide me.

from libsvm.

really help me !!

God bless u !!

from libsvm.

It works! Thanks!! Please take my knee, wa-ha-ha!

It works. You saved me : )

I am on a windows 10 x64 with matlab r2018a and MinGW64.
It works.
You saved me.

when i am going to instal libsvm in r2017a matlab the error is coming like thisError using mex

MATLAB 2018b here. Replace all the CFLAGS by COMPFLAGS. Works perfectly!

from libsvm.

It works. Thanks !!!!

from libsvm.

Thanks God！It works！Thank you!

Thank you

I am on win10 x64 and I also use R2016a. I installed tdm64-gcc-4.9.2 in C:\TDM-GCC-64, then replaced all the CFLAGS by COMPFLAGS. I also restarted the Matlab. But it doesn't work.... Please help me!!!

Hi cjlin1, I am not clear your mention. I put all code to C:\WINDOWS, right?. But it doesn't work.
gcc: error: -fexceptions: No such file or directory
However, I find another answer:
mex -O -largeArrayDims abc.c
mex -O -largeArrayDims xyz.c
mex -O -I.. -largeArrayDims yuh.c ../svm.cpp yuh1.c
mex -O -I.. -largeArrayDims ngh.c ../svm.cpp ngh1.c
It works for me. What is the difference between this way and the previous way of compiling LibSVM? Are there any disadvantages of using this way?

from libsvm.

from libsvm.

Yes, I see.
However, maybe I need to change something to make it suitable for my data, so I need a recompile to mex file. Can I use "mex -O -largeArrayDims...." instead?

Thank you

from libsvm.

thanks a lot !...

Hi, thanks a lot. That worked <3

OMG, I forgot to restart matlab!!! That worked!!!

I am on a windows 10 with matlab r2015b and MinGW64. When I run make.m I encountered with gcc: error: \-fexceptions: No such file or directory. I solved it by changing CFLAGS to COMPFLAGS.

Thank you so much...

from libsvm.

Thanks. It's working. I spent around 5 hours.

Please note that the 'CFLAGS' is in the scripts. You need to replace all 'CFLAGS ' with 'COMPFLAGS'. Remember it is all.

Thank you!

That's amazing! Thanks a lot!

We have tested it in both MinGW64 and Visual Studio 2019 compilers in MATLAB, and ``-std=c99'' is no longer needed.

The aforementioned part will be updated in the future.
Thank you.

from libsvm.

Really useful !!!

Hi guys, I read the introduction above, and I can’t find the word "CFLAGS" in my make.m file. Please tell me how to solve this problem, thank you

By the way, my matlab version is R2019a and I use libsvm-3.25
