Does anyone know how to link against miniupnpc (https://github.com/miniupnp/miniupnp/tree/master/miniupnpc) on Windows 10? I am using bazel 5.0. I am using msys2 and the mingw-gcc compiler. I am linking against the static form using -DMINIUPNP_STATICLIB. I compiled it by typing make install. I also tried mingw32make.bat but the fails with a different error. I get the following error when linking.

You need to run the following commands
cmake .
make
./mingw32make.bat
Then you need to use the libminiupnc.dll.a

I'm trying to implement nested functions in llvm through the C++ API. After i perform a semantic check (to assure that the program which is going to be compiled has correct nesting references etc) i define all function in the same scope in llvm and set all variables as global. I was expecting this to work but i found myself having huge problem while getting an executable from an .o file with the command:
"llvm-as-3.8 output.ll| llc-3.8 -filetype=obj | clang-3.8 ../library/library.a -v -o out"
By using either llvm::GlobalValue::WeakAnyLinkage or llvm::GlobalValue::ExternalLinkage linkage for global variables i get:
/usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 11
/usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 1 has invalid symbol index 12
/usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info): relocation 8 has invalid symbol index 12
...
/usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_line): relocation 0 has invalid symbol index 2
/usr/bin/../lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
Which seems to have to do with the definition of main, who in the definition of my ir code stands as:
; Function Attrs: nounwind uwtable
define void #main() #0 {
The thing is that the same command didn't have any problem when i didn't use global variables except of course the case where a variable was used in a child function, which was the reason i tried to change alloca to global.
Help find a solution to this problem.
Thanks in advance.
Note1: I use llvm-3.8
UPDATE:
when i removed -v from the clang command the result was:

Where all this variables were defined at the start of my program in llvm IR as:
#x = external global i32*
#n = external global i32
#i = external global i32
#changed = external global i1
#x.1 = external global i32*
#y = external global i32*
#t = external global i32
#msg = external global i8*
#x.2 = external global i32*
#n.3 = external global i32
#i.4 = external global i32
#const_string_temp = private constant [3 x i8] c", \00", align 1
#const_string_temp.5 = private constant [2 x i8] c"\0A\00", align 1
#i.6 = external global i32
#x.7 = external global i32
#seed = external global i32
#const_string_temp.8 = private constant [16 x i8] c"Initial array: \00", align 1
#const_string_temp.9 = private constant [15 x i8] c"Sorted array: \00", align 1
I hope this helps you help me --- or else find the problem in my IR code generation.
I'm looking forward to it..
#x = external global i32*
and so on are global variable declarations, not definitions. Therefore, the "undefined reference" error is valid and you really need to define them.
See http://llvm.org/docs/LangRef.html#global-variables for more information
Also note that llvm-as / llc part is redundant - clang could compile .ll / .bc files just fine.
I installed opencv with static linking on pandaboard using BUILD_SHARED_LIBS=0 option. I am using ubuntu 11.10. I also built 3rd party libraries png, jpeg, jasper and zlib. (cmake options BUILD_PNG=ON BUILD_JASPER=ON BUILD_JPEG=ON BUILD_ZLIB=ON WITH_JPEG=ON WITH_PNG=ON WITH_JASPER=ON). My opencv installation was successful. However when I compile a test program I get a number of undefined reference to errors. All of these errors seem to be related to jpeg, png and jasper libraries but i can't understand why libhighgui is not able to refer to 3rd party libraries when I explicitly link them. Here is how I compile my program :
g++ -static face_recognition.cpp -o fcarm -I/home/nandhini/opencv/2.4.2static/include/opencv -I/home/nandhini/opencv/2.4.2static/include -L/home/nandhini/opencv/2.4.2static/lib/ -L/home/nandhini/opencv/2.4.2static/share/OpenCV/3rdparty/lib -llibjpeg -llibjasper -llibpng -lzlib -lopencv_core -lopencv_contrib -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_flann -lopencv_photo -lopencv_legacy -pthread -lm -lrt -lstdc++ -ldl
I've been stuck with this problem for a long time now and I would really appreciate it if someone can help me solve the problem. Please help, thanks !

The order in which libraries are linked matters! This might be the problem.
I am going to build my Open CV project(C++) in Eclipse, but it gives an error in makefile, the error is
recipe for target `Open_CV.exe' failed
i have also included the lib and opencv in project successfuly, but i don't know why i am getting this error, sometimes i am also getting an error in its subdir file
and Error log is :

I think you missed to link the libcxcore "-lcxcore" (or maybe "-lcvaux").
I'm using opencv on a arm board,with a cortex a8 processor and running on Debian.I wanted to use the processor's fpu to increase the performance of my application,so I succesfully cross-compiled opencv (following this guide) using a toolchain generated for this purpose.
With that said,I dont have experience with working with static libraries.When I compile my code,I get a lot of linking errors.Apparently,they are related with zlib or zlib2,as I've seen on this topic.The thing is,I didn't enabled the png support,but I still get those linking errors:

Can anyone shed a light on what I need to do?What am I missing?
UPDATE:
I tried compiling zlib and bzip2 using the same toolchain,but the error persists.Now I have no idea of what I'm doing wrong.Can anyone help?
I'm running OpenCV 2.3.1 on Ubuntu 11.10. I can compile various program I've written myself wih no issue.
Now, however, I have a half-done Haar cascade, that I need to assemble into the xml-cascade file. For this purpose I need to use the included sample program convert_cascade.c. It is not compiled by default, so I need to do that.
Running gcc like this fails:
gcc -lopencv_core -lopencv_highgui -lopencv_objdetect -I/usr/local/include/opencv/ -L/usr/local/lib/ convert_cascade.c -o convert_cascade
It gives me the following errors:

It seems that all the missing functions areare old C-style OpenCV functions prototyped in core_c.h. But including that ( #include <opencv2/core/core_c.h> ) makes no difference. I also tried compiling with the -lopencv_legacy flag (basically just a guess that it might have something to do with older functions), to no avail.
What should I do in order to compile it?
There should be a build_all.sh script in the /samples/c/ directory that will build all the examples for you; no CMAKE tweaks required.
Nevermind. It turned out I had to recompile OpenCV anyway in order to enable TBB, so I simply gave CMAKE the BUILD_EXAMPLES=ON command, and now I have it in a compiled version. I'm pretty sure that is not the proper solution though ;-)
