Kindly help to build OpenSAR software in AWS Ubuntu VM.
I am trying to build OpenSAR software
git clone https://github.com/parai/OpenSAR.git
using the following make command
make BOARDDIR=stm32_stm3210c CROSS_COMPILE="arm-none-eabi-" BDIR=boards/stm32_stm3210c/examples/com_simple CFLAGS=-D__GNUC__ all
But getting the following errors:

Undefined reference to sqrt (or other mathematical functions)
(5 answers)
Closed 5 months ago.
I am trying to call a C function (statslib statistical library) from vala file. My main.vala file is as follows:
extern double sum(double[] doublelist, int len);
public static void main(string[] args){
double[] numlist = {1.1,2.2,3.3,4.4,5.5};
var total = sum(numlist, numlist.length);
stdout.printf("The sum is %f \n", total);
However, on trying to compile with C file, I get following error:

collect2: error: ld returned 1 exit status
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)
If I remove all functions (except sum) from statlib.c file, the command works perfectly and creates an executable file.
How can I avoid getting above errors without changing statlib.c file?
You need to tell the compiler that you want to link math library
Add -lm to your command line
https://godbolt.org/z/dPn9b7rrs
I have a source, that I'd like to build and link against the libav library on Linux.
I followed the compilation guide of ffmpeg here: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
Everything works.
I build the included examples like this: FFmpeg: building example C codes
It also works.
Now, I'd like to build my own little applications, where I try to learn about using libav. My current problem is, that by using the command line
gcc muxing.c -g -I ../../../ffmpeg_build/include/ -L ../../../ffmpeg_build/lib/ -lavdevice -lavformat -lavfilter -lavcodec -lswresample -lswscale -lavutil -lm -lz -lpthread -lfdk-aac -lmp3lame -lx264 -lva -lX11
I get to this point:
muxing.c: In function ‘write_audio_frame’:

Then I read, in order to overcome this linker error, I have to append -ldl to my command line, but then I get this:

So, what can I do, to get it compiled and linked fully?
I using CLion to write my project,Windows 10 is my OS.
I use MinGw to compile the source code with CMAKE,
and following the wrong message

How to fix the error?
I'm trying to compile COSEG, a program from the RepeatMasker developers (link: http://www.repeatmasker.org/COSEGDownload.html) on Xubuntu.
After unpacking the distribution I enter the directory and try to run make in my terminal but I get many "undefined reference to" errors:

make: *** [coseg] Error 1
Searching the internet I have found that probably it is a 'linking' problem and I have to add/modify some lines of code in the makefile but this kind of stuffs are very new to me and I am not a programmer, so I feel a bit confused.
Do you have some tips or suggestions to help me to solve this problem, please?
Thank you very much for your time!
Massimiliano.
Update:
Trying to compile the previous version of the program, gives me an additional warning:

Some linkers (including yours) need to have the libraries specified after the object files (or other libraries), which use symbols from it. This can even lead to the necessity to specify libraries multiply if cyclic dependencies are involved.
In your case coseg.o uses symbols from libm, so you would have to specify -lm after coseg.o in your command: cc -O4 version.o coseg.o -lm -o coseg
I suggest you change your Makefile to:
##
## Makefile for coseg project
##
VERSION=0.2.2
INSTALLDIR=/usr/local/coseg-${VERSION}
## Basic
CC = cc
CFLAGS = -O4
LDFLAGS = -lm
## A nice memory leak checker:
#CC = bgcc -O4 -fbounds-checking -lm
all: coseg
version.c: Makefile
echo "char const* Version = \"$(VERSION)\";" > version.c
coseg: version.o coseg.o
${CC} version.o coseg.o ${LDFLAGS} -o coseg
... rest of makefile ...
That should fix your problem.
I want to use standard c function in one of my function
void print(const char* format,...) {
char buffer[256];
va_list args;
va_start (args, format);
vsnprintf (buffer,256,format, args);
va_end (args);
sendString(buffer);
}

In the target all it fails in linking. I have tried the example with arm-elf toolchain there also i am getting some errors.I have googled a lot for it but did not find any solution for it.
Try using gcc as ld frontend.
Change:
$(TOOLCHAIN)ld -o check.elf [...]
into
$(TOOLCHAIN)gcc -o check.elf [...]
GCC knows to add some necessary options when invoking ld.
Do things go any better when adding "-lgcc" to -L?
instead of using ld for linking i used gcc but it was including the supplied crt.o object file so i used -nostartfiles and it worked for me.
