mex cc file in ubuntu - matlab

I've download some code online. The makefile is like following:
all: cascade
cascade: cascade.cc model.cc model.h
mex -o cascade \
CXXFLAGS="\$$CXXFLAGS -O3 -march=nocona -fomit-frame-pointer" \
cascade.cc model.cc
clean:
rm *.mex*
I use command !make to run in matlab. But it gives me the following error:
mex -O cascade \
CXXFLAGS="\$CXXFLAGS -O3 -march=nocona -fomit-frame-pointer" \
cascade.cc model.cc
/bin/sh: 1: mex: not found
make: *** [cascade] Error 127
I go to /bin/sh of my system. There is no mex indeed.
What should I do to add mex to /bin/sh.
Thanks

MySQL Workbench for PostgreSQL - ./psqlodbc.h:41:10: fatal error: 'sql.h' file not found

I am trying to connect to a Postgres db trough MySQL Workbench.
Following the documentation we need to install a driver for psql in our machine.
I am running a MacOS Big Sur 11.2.3.
After run CFLAGS="-arch i386 -arch x86_64" make I'm getting the following error:
/Library/Developer/CommandLineTools/usr/bin/make all-am

^~~~~~~
1 error generated.

make: *** [all] Error 2
It seems that the 'sql.h' file is not found.
How to solve this issue?

Boost.Python Link Error with Python3 and virtualenv

I got the following error when I tried to compile .cpp file with clang++.
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I set up Python and boost-python as follows.
Python
I installed Python 3.6.0 using pyenv-virtualenv (via homebrew)
Boost-Python
I used homebrew in Python 3 environment.
$ source activate py36
$ brew install boost-python --with-python3 --without-python
~/.bash_profile
My ~/.bash_profile looks like this:
export PYENV_ROOT="/usr/local/var/pyenv"
export PYENV_VIRTUALENV_DISABLE_PROMPT=1
export CPLUS_INCLUDE_PATH="$CPLUS_INCLUDE_PATH:/usr/local/var/pyenv/versions/3.6.0/include/python3.6m/"
if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi
if which pyenv-virtualenv-init > /dev/null; then eval "$(pyenv virtualenv-init -)" ; fi
Test cpp
This is the file I tried to compile and failed (saved as test.cpp).
#define BOOST_PYTHON_STATIC_LIB
#include <boost/python.hpp>
using namespace boost::python;
char const* say(){
return "hello, world";

Matlab Mex compilation error

I’m using the Random Forest library for Matlab (link). I’m using it for classification. On Windows it works very well out of the box (precombiled mex files) but I also want to run it on a CentOS cluster.
I have tried to compile it on the cluster by executing make mex but I’m getting an error. The output is as follows:
rm twonorm_test -rf
rm tempbuild/*.o *.o -rf

Does somebody knows how to solve this issue? If you want, you can take RF_MexStandalone-v0.02.zip from the above link and then go to randomforest-matlab/RF_Reg_C/Makefile.
Edit: I have change -o to -output but now the output is the following:

cc1plus: error: unrecognized command line option "-std=c++11"
make: *** [mex_classRF] Error 255
I did not find an option -std=c++11 in the makefile.
The error is quite self-explanatory: the option -o is not recognized. If you type mex -help you see the options mex accepts. Try to replace -o with -output.
EDIT regarding the std=c++11 option, you are probably using an old version of gcc compiler. You can either change it to std=c++0x which is the equivalent option (but note that some features of the c++11 standard may not be present\implemented), or upgrade to an up-to-date version of gcc.
If you need more help, please report the output of g++ --version.

How do I fix "gcc: winrespp.rc: No such file or directory" during compiling PAR::Packer on Cygwin?

I have tried to install PAR::Packer in Cygwin for Windows on a 32 bit machine, so I executed cpan pp.
I am facing the following problem.
gcc-4 -c -DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -g -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -I/usr/lib/perl5/5.14/i686-cygwin-threads-64int/CORE -DPARL_EXE=\parl.exe\ -O3 main.c windres -F pei-i386 -i winres\pp.rc -o winres\pp.res
gcc: winrespp.rc: No such file or directory
gcc: warning: '-x c' after last input file has no effect
gcc: no input files
windres: preprocessing failed.
Makefile:735: recipe for target ppresource.coff failed
make[1]: *** [ppresource.coff] Error 1
make[1]: Leaving directory /home/prabhakaran.srinivas/.cpan/build/PAR-Packer-1.013-eTAwxL/myldr
Makefile:594: recipe for target subdirs failed

make -- NOT OK
CPAN: YAML loaded ok (v0.81)
Running make test
Can't test without successful make
Running make install
Make had returned bad status, install seems impossible
The problem is in myldr/Makefile.PL:
$pre_res = qq(winres\\pp.res);
$rt_cmd = qq(windres -F pei-i386 -i winres\\pp.rc -o $pre_res);
$res_cmd = qq(windres -o ppresource.coff $pre_res);
$res_section = $res;
and, later,
$res_section:
$rt_cmd
$res_cmd
Under Cygwin's bash, winres\pp.rc would be interpreted as winrespp.rc instead of winres/pp.rc. The correct way would be
$pre_res = catfile(winres => 'pp.res');
$rt_cmd = join ' ' => qw(windres -F pei-i386 -i), catfile(winres => 'pp.rc'), '-o', $pre_res;
etc.
