I got Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd' using mlr when training the learner. Any suggestions on how to fix it?

I am trying to read 5x^2 but octave says that it's wrong also it allows us to put (sin(x/2))^3
clc; close all; clear;
pkg load symbolic;
syms x;
f=input("Introduce la funcion ");
diff(f,x)
also there is the output with both cases
case (sin(x/2))^3
Introduce la funcion (sin(x/2))^3
ans = (sym)
2/x\ /x\
3*sin |-|*cos|-|
\2/ \2/
----------------
2
case 5x^2
Introduce la funcion 5x^2
parse error:
syntax error
>>> 5x^2
^
error: called from
symbolic at line 6 column 2
When I run this code:
y = 2 + x^2 + 0.5*x^3
x <- seq(-10, 10, .1)
qplot(x,y,geom="line")
it works fine and the graph shows up. The only problem is when I try to knit the rmd to html an error pops up regarding the first line of code:
y = 2 + x^2 + 0.5*x^3
The error says: Error in eval(expr, envir, enclos) : object 'x' not found Calls: ... handle -> withCallingHandlers -> withVisible -> eval -> eval Execution halted
It's referring to the x in the equation because thats the line where the error occurs. I don't know how to make it knit and have not seen other people encounter this specific problem. Any help is appreciated.
I realize I need to define QCOM has the vendor somewhere, but which file / where is this typically declared?
I am getting the following exception while building the ROM for a lineageos project and need some help diagnosing and resolving the issue:

I don't know the long term fix for this issue, but my quick and dirty fix was to define the variable in both of the files that depend on it.
I went into the file hw_info_drm.cpp and added the following at the top:
#define QCOM 1
I'm trying to compile libpd to javascript or webassembly using emscripten sdk. According to some docs, if there is a Makefile, it can be compiled by using emmake make, (emconfigure is not used because there is no ./configure file), but I get the following error:

Any ideas? Do you think is possible to compile this library?
UPDATE: After tweaking every complaining file as suggested in #zakki 's answer
I get another error:
libpd_wrapper/util/ringbuffer.c:18:12: fatal error: 'stdatomic.h' file not found
#include <stdatomic.h>
That file have this content:
#if __STDC_VERSION__ >= 201112L // use stdatomic if C11 is available
#include <stdatomic.h> // HERE IS WHERE ERROR GOES
#define SYNC_FETCH(ptr) atomic_fetch_or((_Atomic int *)ptr, 0)
#define SYNC_COMPARE_AND_SWAP(ptr, oldval, newval) \
atomic_compare_exchange_strong((_Atomic int *)ptr, &oldval, newval)
//Some other definitions that I didn't put here
I read some threads some time ago about this problem with C++11, how can i fix this?
UPDATE 2: After adding && !defined(__EMSCRIPTEN__) now is able to compile, but I'm getting this warning that I don't understand:
WARNING:root:Dynamic libraries (.so, .dylib, .dll) are currently not
supported by Emscripten. For build system emulation purposes,
Emscripten will now generate a static library file (.bc) with the
suffix '.so'. For best practices, please adapt your build system to
directly generate a static LLVM bitcode library by setting the output
suffix to '.bc.')
Emscripten has endian.h. So add defined(__EMSCRIPTEN__) to ifdef.
#if defined(__linux__) || defined(__CYGWIN__) || defined(__GNU__) || \
defined(ANDROID) || defined(__EMSCRIPTEN__)
#include <endian.h>
#endif
Second, it seems like Emscripten bug.
#if __STDC_VERSION__ >= 201112L && !defined(__EMSCRIPTEN__)
Have a file called f.m which has the following:
function xdot = f (x,t)
xdot = -exp(-t)*x^2;
endfunction
x=lsode("f",2,(t=linspace(0,5,50)'));
plot(t,x)
Running in octave 4.2.2 or 4.2.1 produces the following error:
error: 't' undefined near line 2 column 14
error: called from
f at line 2 column 6
