cygwin make error: Specified module could not be found
I was mostly used to dll and lib extensions when using third-party libraries which I used to comfortably incorporate using Visual Studio in my Windows Environment.
But this time, I'm trying to use PicklingTools which has a MakeFile.Linux file which I've been trying to build using make from cygwin.
The version of make is 4.3 while for g++ it is 9.2.0.
Here's the entire MakeFile.Linux source code:
CC = g++
# CC = icc # Intel seems to work

## of some annoying warnings when you compile with -O2 or above

# compile without optimization for that compiler to work

Upon building it (after moving to that directory) using make -f MakeFile.Linux all I get the following error:
Makefile.Linux:61: The specified module could not be found.
Makefile.Linux:61: *** :: failed to load. Stop.
Line number 60-63 is:
load : $(COM_OBJS) load.o
$(CC) $(CCFLAGS) $(COM_OBJS) load.o -o load
And here are the files that are available for C++ directory:
BUILDING textfile mentions that it uses some socket unix libraries which my cygwin environment maybe missing but I can't figure out the exact source of error, here are some relevant lines from BUILDING:
C++: This C++ subdirectory is all raw C++ code. There are no
external dependencies (besides standard UNIX socket code) or libraries
the C++ area needs.
The Makefile.Linux gives examples how to build some code:
% make -f Makefile.Linux all
... will build a bunch of sample programs as well 'libptools.so',
a standalone library for PicklingTools you can link against.
Probably the easist way to use Ptools in your own code is
to compile the libptools.so (using the given Makefile)
and link against it.
% Make -f Makefile.Linux libptools.so
In your own code, make sure you include the following flags to the
compiler (should work for Intel compiler and GNU compiler):
-fno-strict-aliasing -DLINUX_ -DOC_NEW_STYLE_INCLUDES -Wno-deprecated -I/home/me/PicklingTools160/C++/opencontainers_1_8_2/include -I/home/me/PicklingTools160/C++ -pthread -D_REENTRANT
I've tried looking around SO but couldn't find anything similar that could help.
Solution
Unfortunately in newer versions of make, load is a special word and make fails when load is used as a target. This is quite bad, actually, as it violates POSIX etc. There's a Savannah bug open about this. You can work around the issue by using a variable instead:
load = load
$(load) : $(COM_OBJS) load.o
$(CC) $(CCFLAGS) $(COM_OBJS) load.o -o load
