this is an issue during the linking of a program that includes the gnu plotutils package, specifally the libplotter library.
The "program":
#include <plotter.h>
int main() {
return 0;
}
complication commands and errors:

I already tested most of the libtool library options in the g++ linking command but this wouldn't fix the g++ linking problem.
Anyway, after the successful linking with libtool, the libplotter library is not listed by ldd:
ldd test
linux-vdso.so.1 (0x00007ffffbda4000)
libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/libstdc++.so.6 (0x00007f8c8df0a000)
libc.so.6 => /lib64/libc.so.6 (0x00007f8c8dd50000)
libm.so.6 => /lib64/libm.so.6 (0x00007f8c8dc1b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f8c8e118000)
libgcc_s.so.1 => /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/libgcc_s.so.1 (0x00007f8c8dc01000)
Can someone explain what is wrong with the g++ linking command as compared to the working one with libtool?
Thank you
I am new to stack overflow so hope this helps! I ran into the same problem and all I had to was to reinstall ld via this command:
sudo apt reinstall binutils
If that doesn't work try reinstalling g++ via this command:
sudo apt reinstall g++

Ok, thanks to #vre i figure it out.
The solution :
Download vlc-qt and vlc 3.0.16 and extract.
Open cmake-gui choose your visual studio and check "Specify native compilers".
Set compilers to the correct MSVC like in the image
Add entries.. or just click "Configure" and fill it like in the image
After you fill all the entries and there no errors click "Generate"
Click "Open Project" to open it via Visual Studio and Build ..
I am trying to build Tensorflow 2.0 on Ubuntu 16.04LTS
I get the error with gcc 4.8, gcc 5, gcc 9.2, etc.
Here are the version of bazel and gcc:

(ai) ubuntu#ip-10-0-1-71:~/tensorflow$ gcc --version
gcc (Ubuntu 9.2.1-17ubuntu1~16.04) 9.2.1 20191102

Any ideas?
This might happen if you have your config set such that warnings are errors.
Looking at the above it would appear that a compiler warning that is treated as a warning in TF OSS builds, your build is treating as an error.
I'm trying to write a makefile to compile Objective-C with Cocoa on Linux.
I have installed the following packages:
sudo apt-get install gnustep gnustep-devel
I started with a minimal makefile, which compiles successfully:
FLAGS = $(shell gnustep-config --objc-flags)
LIBS = $(shell gnustep-config --base-libs)
all:
gcc $(FLAGS) HelloWorld.m $(LIBS) -o a.out
Here is the sole source file:
#include <Foundation/Foundation.h>
int main(int argc, const char* argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSLog(#"Hello, World!");
[pool drain];
return 0;
}
Now I'm trying to write a more elaborate makefile but I haven't been able to get it working yet:
CC = gcc
SOURCES=HelloWorld.m
OBJECTS=$(SOURCES:.m=.o)
CFLAGS=-c $(shell gnustep-config --objc-flags)
LIBRARIES = $(shell gnustep-config --base-libs)
FRAMEWORKS:= -framework Foundation -framework Cocoa -framework AppKit
LDFLAGS=$(LIBRARIES) $(FRAMEWORKS)
EXECUTABLE=a.out
all: $(SOURCES) $(EXECUTABLE)
$(EXECUTABLE): $(OBJECTS)
$(CC) $(LDFLAGS) $(OBJECTS) -o $#
.m.o:
$(CC) $(CFLAGS) $(LIBRARIES) $< -o $#
Output:

Actually I think I see the problem, my gnustep-config --base-libs outputs -L/home/brett/GNUstep/Library/Libraries which does not exist in my environment. I will update if I figure out how to properly install the libraries.
It appears as if the gnustep-devel package only installed the docs:
$ dpkg-query -L gnustep-devel
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/gnustep-devel
/usr/share/doc/gnustep-devel/copyright
/usr/share/doc/gnustep-devel/changelog.gz
I found some files under /usr/share/GNUstep but no Foundation.h:
$ find . -name *.h
./Makefiles/TestFramework/ObjectTesting.h
./Makefiles/TestFramework/Testing.h
You may want to try this :
CC = gcc
SOURCES=HelloWorld.m
OBJECTS=$(SOURCES:.m=.o)
CCFLAGS=`gnustep-config --objc-flags` -c
OBJCLIBS=`gnustep-config --objc-libs` -lgnustep-base
EXECUTABLE=a.out
all: $(SOURCES) $(EXECUTABLE)
$(EXECUTABLE): $(OBJECTS)
$(CC) $(LDFLAGS) -o $# $^ $(OBJCLIBS)
%.o : %.m
$(CC) $(CCFLAGS) -o $# -c $<
I did not check in detail but with your makefile all "-I" directives are missing like this :
-I/usr/local/include/GNUstep -I/usr/include/GNUstep
While I was trying to build Plasma5 on Ubuntu Trusty, I got an issue related to eglibc 2.19.
/usr/lib/x86_64-linux-gnu/libc_nonshared.a(lstat64.oS): In function ``lstat64':
(.text+0xc): undefined reference to ``__lxstat64'
I have no idea how to fix this. Thanks.

I ran into the exact same problem trying to do the exact same thing. I don't know if this is a good solution, but I found three ways to fix this problem.
run the compile command and add
"/usr/lib/x86_64-linux-gnu/libc_nonshared.a" to it
run the compile command and add "-lc" to it
the best solution if you're using kdesrc-build is to add the option to the baloo module in your .kdesrc-buildrc like this:
options baloo
cmake-options -DCMAKE_CXX_FLAGS="-lc"
end options
After some hoops and hurdles I was able to build and run Plasma 5 on Ubuntu 14.04 and will probably write a guide on how to do it.
Here is a Makefile:
all: main
bar.cxx:
echo "void bar(){}" > bar.cxx
foo.cxx:
echo "void bar();" > foo.cxx
echo "void foo(){ bar(); }" >> foo.cxx
main.cxx:
echo "void foo();" > main.cxx
echo "int main(){ foo(); }" >> main.cxx
%.o: %.cxx
g++ -c -fPIC $<
libbar.so: bar.o
g++ -shared -o libbar.so bar.o
libfoo.so: foo.o libbar.so
g++ -shared -o libfoo.so foo.o -L. -Wl,-rpath,\$$ORIGIN/. -lbar
main: main.o libfoo.so
g++ -o $# main.o -L. $(PWD)/libfoo.so
clean:
rm -rf *.so *.o *.cxx main
which fails like this on Ubuntu 14.04:
$ make
echo "void foo();" > main.cxx
echo "int main(){ foo(); }" >> main.cxx
g++ -c -fPIC main.cxx
echo "void bar();" > foo.cxx
echo "void foo(){ bar(); }" >> foo.cxx
g++ -c -fPIC foo.cxx
echo "void bar(){}" > bar.cxx

/usr/bin/ld: warning: libbar.so, needed by /media/david/data/tmp/origin/libfoo.so, not found (try using -rpath or -rpath-link)

collect2: error: ld returned 1 exit status
make: *** [main] Error 1
RPATH is set relative:
$ objdump -p libfoo.so | grep RPATH
RPATH $ORIGIN/.
ldd print the correct path to libbar.so:
ldd libfoo.so
linux-vdso.so.1 => (0x00007ffe3f1c8000)
libbar.so => /media/david/data/tmp/origin/././libbar.so (0x00007f83c29ff000)
I have some questions, maybe in wrong order or redundant:
0) Why ld can't find libbar.so?
1) Why do I need to add -Wl,rpath,$(PWD) like below, while libfoo.so already contains the rpath?
main: main.o libfoo.so
g++ -o $# main.o -L. -Wl,-rpath,$(PWD) $(PWD)/libfoo.so
2) LD_LIBRARY_PATH=. make solve the problem, but why? I was thinking the LD_LIBRARY_PATH was used only at execution.
3) Why does -L. has no effect?
