Problem in the build MVE and UMVE step

[simonfuhrmann]

Please install the required libraries, libpng, libjpeg and libtiff, to resolve the first issue. This is documented here:
https://github.com/simonfuhrmann/mve#building-mve-and-umve

To resolve the second issue, please try adding || defined(__arm__) to the end of this line:

mve/libs/util/system.h

Line 149 in b9eba7e

# elif defined(__i386__) || defined(__x86_64__)

Have you tried removing the -march option altogether? It'll give you slower code, but the native option is fairly new, see here: https://www.phoronix.com/scan.php?page=news_item&px=LLVM-Clang-march-native-M1

[simonfuhrmann]

I am pretty sure the M1 is a little endian CPU, so it should be on the same line as i386. Specifying the wrong LE/BE is not dangerous, but you'll probably run into weird issues and fundamentally, the software won't work.

[simonfuhrmann]

The endian issue should be fixed for M1 processors with 354a652.

Hello. I need your help. Because I need to install MVE for a paleontologic proyecto of University of Extremadura. Please, do you help me?

[dectun]

Ok. I do this;

first: put the command on system.h file
second: try the steps of the link. The git clone well. But when I put make -j8, I get an error like this; "clang: error: the clang compiler does not support "-march=native"
third: I revised the code of makefile.inc file. I have put the correcto form; -mcpu=apple-m1.

I give you a screemshots. I want to said you, thanks for the help.

hello. I try the brew doctor. And it get me this;

I don`t know what is the wrong step.

I need install MVE software because I read it is the best free software to rebuild surfaces for fotogrametric tecnics. In the departament of paleontologic have a hypothesis to obtain a high resolution of fossil pieces. And we need install in a MacOS, because it si the software system that uses in the departament.

I haven´t a good level english. So sorry about the wrong sentences in english.

Hello. good afternoon from Spain.

In the first time I need to say you and the other maintainer, developer, GO, admin, ...that you are helping me. VERY MUCH THANKS FOR ALL.

I read the link. And I understand this; the option -march:native not is very important to work MVE. Only this is important to optimice the compiler of code.

But I don`t know what is the way to remove this option.

And Since yesterday I´m thinking if is necessary defined the both in BE. And if I can change the command "(arm)" or "(aarch64) to the line 147 in the file systmen.h .
What do you think about this? is it possible? is it dangerous? it is not right?....

Closing this for now.
