matching substring beginning with special characters without using external commands - fish

I would like a function, abc123, which is called as:
abc123 -std=c++17 -Wall -lstdc++ -lpthread -o xxx xxx.cpp yyy.cpp
I would like to collect all substrings beginning with "-l" in the arguments.
Here is what I am running into:
%> echo (string match "l*" (string split " " "std=c++17 Wall lstdc++ lpthread o xxx xxx.cpp"))
%> lstdc++ lpthread
This is fine. But the following will result in an error as the hyphons are interpreted as options:
echo (string match "-l*" (string split " " "-std=c++17 -Wall -lstdc++ -lpthread -o xxx xxx.cpp"))

You just need to add -- to separate options from arguments:
string match -- "-l*" (string split -- " " "-std=c++17 -Wall -lstdc++ -lpthread -o xxx xxx.cpp")
# ...........^^.....................^^
-lstdc++
-lpthread

rpmbuild bad exit status error while creating binary RPM

It is my first time creating RPM package and I followed this documentation to build a simple RPM package. I created source RPM but I can't create binary RPM.
Here is the result when I execute rpmbuild --rebuild /SRPMS/bello-0.1.1.el8.src.rpm:

Why make utility cannot find header file?

I have been working in Eclipse based IDE called Vitis (IDE from Xilinx).
I have an automatically generated software project containing three automatically
generated Makefiles. Organization of the project is following:
zynq_fsbl
-Makefile_level_01
-main.c

My problem is that I am not able to compile the driver_peripheral_01.c module due to the problem with
Config.h header file inclusion. The "fatal error: Config.h: No such file or directory" is being invoked despite the fact that I have copied the header file in question into the include subdirectory in project directory structure. Does anybody have any idea why the make cannot find the Config.h header file? Thanks for any suggestions.

Generic mexopts file for GCC/Clang OSX/Linux [R2014b]

It is a recurrent pain in the ice to set up this blurry mexopts.sh... I would just like a generic configuration that works with all combinations of:
Ubuntu 14+ and OSX 10.10+;
gcc 4.8+ and clang 3.5+
I don't want any dependence to Xcode for the OSX part, I don't mind editing that file manually to change version numbers occasionally, and I don't care about warnings regarding the GCC version.
Here is my chaotic mess so far, hopefully with a little help we can finally get something decent:
#
# mexopts.sh Shell script for configuring MEX-file creation script,
# mex. These options were tested with the specified compiler.
#
# usage: Do not call this file directly; it is sourced by the
# mex shell script. Modify only if you don't like the
# defaults after running mex. No spaces are allowed
# around the '=' in the variable assignment.
#
# Note: For the version of system compiler supported with this release,
# refer to the Supported and Compatible Compiler List at:
# http://www.mathworks.com/support/compilers/current_release/
#
#
# SELECTION_TAGs occur in template option files and are used by MATLAB
# tools, such as mex and mbuild, to determine the purpose of the contents
# of an option file. These tags are only interpreted when preceded by '#'
# and followed by ':'.

You can see that I'm trying to get a different section for each combination arch_compiler. I can then manually select the compiler I want simply by ORing the case choice with the target architecture.

I can't get "math.h" to work with eclipse kepler using "gcc arm"

I used this tutorial to setup all of my software: http://www.angstromsandalgorithms.com/free-eclipse-arm-gcc-openocd-toolchain-for-windows-part-3-eclipse-ide/
I'm using an STM32F405RGT6 arm. I'm also on windows. I have tried adding -lm everywhere in the makefile and havn't had anything work. Basically I just want to be able to #include "math.h" so I can use the math functions...I'm also assuming placing -lm in the right place is all I need to do from all the google searches I've done...I'm also thinking my makefile might be not be linking things correctly and/or i might not have things linked properly in eclipse.
Here is my makefile:

Compiling from matlab using mex functions.cpp works fine
edit:
Thanks for the hints!
Solved (but not understood):
Changing the order in residualfm: residualfm/functions.o from:
$(MEX) $(MEXFLAGS) $(LIBS) -o $(MEXDIR)/$#.$(MEXSUFFIX) $^
to
$(MEX) -o $(MEXDIR)/$#.$(MEXSUFFIX) $^ $() $(MEXFLAGS) $(LIBS)
solved the problem. Can someone explain this?
(Solved in the comments and edits. See Question with no answers, but issue solved in the comments (or extended in chat) )
