fatal error: math.h: No such file or directory

[simonbyrne]

Try:

sudo apt-get install build-essential

(tip from https://forums.linuxmint.com/viewtopic.php?t=161241#p830537)

Then in Julia:

Pkg.build("Rmath")

[tkelman]

I'm a little surprised you can somehow have gcc installed but without working system headers

[simonbyrne]

@negar6 what does that have to do with this package?

[simonbyrne]

Again, why are you asking here? This is an issue tracker about a completely unrelated package in a completely different language. Might I suggest you try https://www.mathworks.com/matlabcentral/

[simonbyrne]

However I would suggest that you look into using https://github.com/JuliaImages/Images.jl: I've found it to be much more pleasant to use than Matlab.

[nalimilan]

What OS are you using?

[cossio]

@nalimilan Ubuntu 16.04.1 Desktop, 64 bit.

[nalimilan]

Does /usr/include/math.h exist?

[simonbyrne]

agreed, it's a bit weird, but apparently libc-dev is only a "recommends" of gcc.

[nalimilan]

I thought recommended packages were installed by default on Ubuntu?

[cossio]

maybe build-essentials should be added as a requirement of Rmath? It should be on the documentation.

[simonbyrne]

Just to confirm: did that fix it?

[cossio]

@simonbyrne Yes, installing build-essential fixes the problem.

[simonbyrne]

Should we add a check for this?

[cossio]

@simonbyrne I think you should either install it, or raise an error somewhere more informative, that actually says what is missing and how to solve it.

[tkelman]

a configure script would check for this kind of thing but bury the actual error deep in a config.log file

[simonbyrne]

Bites again:
https://discourse.julialang.org/t/rmath-issues/5984

We really need a good solution to this.

[simonbyrne]

Should also throw an error if no Xcode tools installed, see JuliaStats/Rmath-julia#23

[andreasnoack]

Should be fixed by #55

[negar6]

why????

mex -largeArrayDims -O jpeg_read.c
Building with 'MinGW64 Compiler (C)'.
Error using mex

[ararslan]

...or Julia at all

[negar6]

i have matlab 2018 a and want to work by jpeg toolbox.it's necessary to use c compiler so added int by add on.and jpegtbx v 1.4 in project path. but after executing "mex -largeArrayDims -O jpeg_read.c", this error displayed:"D:\Program Files\MATLAB\R2018a\bin\jpeg_read.c:52:20: fatal error: jerror.h: No such file
or directory
compilation terminated."
after this, downloaded .h file and saved it in extern/ include.but now i have these ERRORSSSSSSSS:
