When compiling with “make xxx=0”, the message displayed on the terminal is not displayed, but when compiling with “make xxx=1”, a message about the build process is displayed on the terminal window when compiling.

I'm now compiling wxWidgets' hello world sample: https://docs.wxwidgets.org/trunk/overview_helloworld.html
using MingGW-w64 and it's mingw32-make on windows, and I'm using the pre-compiled Windows binaries it provides.
I have already compile successfully using
g++ -o hello -I/d/local/wxWidgets/lib/gcc810_x64_dll/mswu -I/d/local/wxWidgets/include -L/d/local/wxWidgets/lib/gcc810_x64_dll hello.cpp -lwxbase31u -lwxmsw31u_core
(I run this git-bash), and it can be execute normally too.
But when I copy the same line into makefile like this:
all: hello
hello: hello.cpp
g++ -o hello -I/d/local/wxWidgets/lib/gcc810_x64_dll/mswu -I/d/local/wxWidgets/include -L/d/local/wxWidgets/lib/gcc810_x64_dll hello.cpp -lwxbase31u -lwxmsw31u_core
and run with mingw32-make.exe in terminal, this error happened:
hello.cpp:3:10: fatal error: wx/wxprec.h: No such file or directory
#include <wx/wxprec.h>
^~~~~~~~~~~~~
compilation terminated.
mingw32-make: *** [makefile:3: hello] Error 1
I'm not sure if it's the including path problem, because It actually compile successfully when I run the same line in terminal directlty.
Are you also using the "git bash" terminal when you try with your Makefile ?

After trying executing in cmd and git-bash a few times. I found it's probably the path style problem. I tried 2 cases of path specification below:
First:
g++ -o hello -I/d/local/wxWidgets/lib/gcc810_x64_dll/mswu -I/d/local/wxWidgets/include -L/d/local/wxWidgets/lib/gcc810_x64_dll hello.cpp -lwxbase31u -lwxmsw31u_core
Second:
g++ -o hello -ID:\local\wxWidgets\lib\gcc810_x64_dll\mswu -ID:\local\wxWidgets\include -LD:\local\wxWidgets\lib\gcc810_x64_dll hello.cpp -lwxbase31u -lwxmsw31u_core
Git-bash(execute in terminal directly): only first case successfully compiled.
Git-bash(using mingw32-make): only second case successfully compiled.
cmd(execute in terminal directly): only second case successfully compiled.
cmd(using mingw32-make): only second case successfully compiled.
Conclusion: I think mingw32-make using "traditional" Windows path style (backslash), even under git-bash.
Update:
I found that mingw32-make also support forword slash, so I can rewrite as:
g++ -o hello -ID:/local/wxWidgets/lib/gcc810_x64_dll/mswu ...
So I think it's better to use relative path in makefile, to prevent that (D:) in path, and also more portable(unix/linux use backslash too).
I want to install CD-HIT but 'make' command shows error.
I am running in cygwin (32 bits) so I installed 'make' with apt.cyg and it seems to be correctly installed. Also, I've added the path where CD-HIT are located to $PATH but I still get problems with 'make'.
Here you can see where CD-HIT files are located.
$ pwd
/home/Ale/cdhit-4.8.1
The path is in $PATH
$ $PATH
-bash: /home/Ale/cdhit-4.8.1:/home/Ale/cdhit-4.8.1:/usr/local/bin:/usr/bin:/cygdrive/c/Program: No such file or directory
When using make it shows this error.
$ make -f Makefile
g++ -fopenmp -DWITH_ZLIB -O2 cdhit-common.c++ -c
make: g++: No se encontró el programa
make: *** [Makefile:79: cdhit-common.o] Error 127
I have a suite of Windows programs that up to now I have built under msys, one of which uses libxml2. I am currently trying to switch to building them under msys2 and the latter one is hitting a problem. My updated Makefile includes this:
CFLAGS += -I/mingw32/include/libxml2
$(BINDIR)/%.o: %.c
#-$(MKDIR) $(BINDIR)
$(CC) $(CFLAGS) -c $*.c -o $#
But when I run make (mingw32-make) the compile fails as follows:
[csv-gen]: mingw32-make
gcc -std=c99 -Werror -Wall -D_XOPEN_SOURCE -O -I/mingw32/include/libxml2 -c xmlParse.c -o ../../bin/Win32/csv-gen/xmlParse.o
xmlParse.c:36:27: fatal error: libxml/parser.h: No such file or directory
#include "libxml/parser.h"
^
compilation terminated.
Makefile:66: recipe for target '../../bin/Win32/csv-gen/xmlParse.o' failed
mingw32-make: *** [../../bin/Win32/csv-gen/xmlParse.o] Error 1
Yet that libxml/parser.h file does exist under the /mingw32/include/libxml2 path given by the -I option:
[csv-gen]: ls /mingw32/include/libxml2/libxml/parser.h
/mingw32/include/libxml2/libxml/parser.h
And the strange thing is that if I run the exact same gcc command directly from the msys bash shell (copying and pasting it from the make output above) then it compiles fine with no errors.
And I have the exact same problem with the link phase where it doesn't find the libxml2.a library in the path given to gcc by -L/mingw32/lib, and again I run the gcc link command directly from the shell and it works fine.
So why would gcc's -I/mingw32/include/libxml2 and -L/mingw32/lib options not work when run via mingw32-make yet the exact same options work fine on calling gcc directly from the shell?
I did try making the paths explicit Windows paths (d:/msys64/mingw32/...) and also tried quoting them, to no avail.
It turned out that the answer was to use explicit Windows paths, which as I said above I had tried, but when I tried again it worked so I must have previously made some mistake doing that. I found this by using the output from pkg-config which gives:
[csv-gen]: pkg-config --cflags libxml-2.0
-ID:/msys64/mingw32/include/libxml2
So apparently the problem is that mingw32-make doesn't fully understand the msys filing system, or at least not /mingw32 and /mingw64 paths in it.
Gcc output colored error message and warning message on OS X when use it in the shell, but when use it in makefile, the output message is monochrome.
How to get colored message when use gcc in makefile?
Try adding:
-fdiagnostics-color=always
to your gcc invocation in your Makefile.
I have:
fileMainProgram.cpp
fileClassImplementation.cpp
fileClass.h
makefile
in a directory.
Ran cmd and typed
g++ -make -f makefile
got this message after tinkering with it for a while (change file name/extension, tried without -f, used gcc instead of g++, etc)

This is the makefile, (tried to delete the lines inbetween targets and actions, tried using automatic variables, etc,
I tried to compile the program as
g++ -c fileClassImplementation.cpp
then
g++ fileClassImplementation.o fileMain.cpp
to get an executable and it works fine.

Ran the whole thing on C4droid for my samsung phone and worked fine as is.
Doesn not work on my Windows7 laptop.
What you appear to have is a GNU Makefile, suitable for running GNU Make. Windows doesn't come with GNU Make, so you'll need to download it yourself.
It appears you've already downloaded MingW, try running the mingw32-make command to execute your makefile.
