I am trying to compile a code by Makefile. I received the code from github. I tried to implement the solution from links:
[https://github.com/LLNL/scr/issues/130][1]
[https://stackoverflow.com/questions/62461718/mpi-complile-error-undefined-reference-to-mpiwinfree][2], etc.
These solutions are not working for me or they are too technical. I am sorry to say as I am not from a programming background, it is difficult for me to understand.
The make file are as follows:
Makefile.include
.SUFFIXES: .cxx .cu .f90 .o

I am unable to solve the error. I couldn't compile the code. I will be greatly helped if I can get some clue to compile it.
Thanks a lot.

My code compiles well in codeblocks, but my makefile can't compile because of undefined reference to items with my namespace Chess
how should i specify the namespace in makefile or fix it?
here's the errors example:

You forgot to include board.o when compiling main.exe
I am trying yo build a Makefile for a project that uses the soplex library (which also depends on libz and libgmp).
So I have this little Makefile:
SOPLEXPATH =../../lib/soplex-3.0.0/lib/
SOPLEXINCLUDE =../../lib/soplex-3.0.0/src/
SOPLEXDEP =../../lib/soplex-3.0.0/src/
CC = g++
CPPFLAGS = -g -std=c++0x -O3 -I $(SOPLEXINCLUDE)
#CPPFLAGS += -DNDEBUG
CPPFLAGS += -pg -ggdb
CPPFLAGS += -Wall -Werror=return-type
LIBS = -L $(SOPLEXPATH) -lz -lgmp -lsoplex
SRCS = $(wildcard ./src/core/*.cpp)
OBJS = $(addsuffix .o, $(basename $(SRCS)))
DEPS = $(addsuffix .d, $(basename $(SRCS)))
all : kea
kea : $(OBJS)
$(CC) $(CPPFLAGS) $(LIBS) -o bin/kea-core $(OBJS)
clean :
rm -f bin/kea-core $(OBJS) $(DEPS) *~
-include $(DEPS)
%.d: %.c
#$(CC) -MM -MT $(subst .d,.o,$#) -MT $# $(CPPFLAGS) $< > $#
And all seems to compile to object files (.o) correctly, but then the linker complains about not finding the function soplex::SoPlex::SoPlex() (the constructor of SoPlex):
g++ -g -std=c++0x -O3 -I ../../lib/soplex-3.0.0/src/ -pg -ggdb -Wall -Werror=return-type -c -o src/core/ecircuit.o src/core/ecircuit.cpp

collect2: error: ld returned 1 exit status
Makefile:20: recipe for target 'kea' failed
make: *** [kea] Error 1
Since all the .o files are created I tried to compile by hand doing:
g++ -g -std=c++0x -O3 -I ../../lib/soplex-3.0.0/src/ -Wall -Werror=return-type -pg -ggdb -L/home/diego/Projects/kea-landscape-tool/../../lib/soplex-3.0.0/lib/ -lsoplex -lz -lgmp -o bin/kea-core src/core/main.o src/core/ecircuit.o src/core/solver_soplex.o
And it failed with the same error.
then I tried switching the position of the -L and -l.. flags like this, and it compiled: g++ -g -std=c++0x -O3 -I ../../lib/soplex-3.0.0/src/ -Wall -Werror=return-type -pg -ggdb -o bin/kea-core src/core/main.o src/core/ecircuit.o src/core/solver_soplex.o -L/home/diego/Projects/kea-landscape-tool/../../lib/soplex-3.0.0/lib/ -lsoplex -lz -lgmp
Seeing that, I tried to change the rule in the Makefile as follows:
kea : $(OBJS)
$(CC) $(CPPFLAGS) -o bin/kea-core $(OBJS) $(LIBS)
But it just failed miserably triggering about 100 errors all inside soplex.cpp (as in, it depends on -lgmp and -lz, but it could not find them? Too long to paste here)
I am pretty confused, any idea on how to fix this?
thanks.
Try putting the $LIBS at the end of the command.
Change this:
LIBS = -L $(SOPLEXPATH) -lz -lgmp -lsoplex
Into this:
LIBS = -L $(SOPLEXPATH) -lsoplex -lgmp -lz
You always need to put B after A, if A calls functions in B. With static libraries as least.
I am getting the following error when running make for my CUDA (v7.5) application:
nvlink error : Undefined reference to '_ZN8Strategy8backtestEPddd'
I'm not sure why. It seems something is likely wrong with my Makefile. Here it is -- any ideas what might be causing the error? Thank you in advance!

Note this started happening around the time I added --device-c (which some code changes require).
Turns out objects passed to CUDA kernels cannot have virtual functions. See this thread.
However, it seems that objects instantiated and used only within the kernel can have virtual functions.
I have wrote a simple code which uses c++11 thread. It compiles correct but when I try to run it I have the following error:
terminate called after throwing an instance of 'std::system_error'
what(): Enable multithreading to use std::thread: Operation not permitted

I am using gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1). This is the output of the makefile which I am using

As you can see there is the flag -pthread. What am I doing wrong? Because if I compile a simple code as
g++ threadstest.cc -o threadstest -pthread -std=c++11
everything works fine therefore in my makefile there is something which interferes with -pthread but I don't understand what it is.
Additional information: a workaround which works is to add -Wl,--no-as-needed at the linking stage.
the answer for similar question "Compiling multithread code with g++ (-Wl,--no-as-needed NOT working)"
is
-pthread is a flag for the compiler, not the linker, the right one for the linker is -lpthread
