I'm trying to cross compile a tiny program under Linux for win32. It uses libarchive, which is available in for mingw on my fedora 23 installation (all installed through dnf), but I get lots of linker errors.

Makefile:82: recipe for target 'build/win32/save_the_zazus.exe' failed
make: *** [build/win32/save_the_zazus.exe] Error 1
For this single source file program I just wrote a simple Makefile. The png files aren't in the repo (yet), so just create empty files for them if you try to compile. I tried dynamic and static linking (would prefer static so all I need to do is to pass on a .exe file). For this output I used -static -larchive and it doesn't complain about any missing libraries, but I get all those undefined references.
Add -static -larchive to the end of your command line and try again. The linker isn't getting the library to link against. I've found it needs to be last on the command line.

(I am on Ubuntu) I am trying to run the PortAudio examples, but getting many errors (mentioned below). I have placed the header file portaudio.h in the directory of the program. I have no idea about it. I think it is linker error. Please help!

Assuming you are compiling using gcc and you have a single C file foo.c, the compiler command would be
gcc -o foo foo.c -lrt -lasound -ljack -lpthread -lportaudio
The -l parameters are there to link the required libraries to your program, e.g. -lrt will link librt.a. The order does matter.
I got the required libraries from here: http://www.portaudio.com/docs/v19-doxydocs/compile_linux.html#comp_linux3. Don't know if they are correct. At least you need -lportaudio, obviously.
If the libraries are not found, you have to provide gcc a path, e.g.
gcc -L/usr/lib -o foo foo.c -lrt -lasound -ljack -lpthread -lportaudio
Regarding the header, you don't actually need to copy it into your program's directory. You'd rather include it as
#include <portaudio.h>
and add its directory to the include search path:
gcc -I/usr/include -L/usr/lib -o foo foo.c -lrt -lasound -ljack -lpthread -lportaudio
Of course, all this is better done in a Makefile.
i experience the undefined reference to `dlopen' problems since I have upgraded to ubuntu 13.10 and gcc 4.8.1.
The makefiles are working for years already. the particular call is
gcc -rdynamic -o ov_dbutil ov_dbutil.o libov.so -ldl
The errors are:
libov.so: undefined reference to `dlopen'
libov.so: undefined reference to `dlclose'
libov.so: undefined reference to `dlerror'
libov.so: undefined reference to `dlsym'
collect2: error: ld returned 1 exit status
make: *** [ov_dbutil] Error 1
is it a gcc problem?
ov_dbutil is compiled with the following lines
gcc -g -Wall -O0 -shared -std=c99 -fno-strict-aliasing -DPLT_SYSTEM_LINUX=1 -DPLT_USE_BUFFERED_STREAMS=1 -DPLT_SERVER_TRUNC_ONLY=1 -DNDEBUG -DOV_SYSTEM_LINUX=1 -I../../../plt/include/ -I../../../ks/include/ -I../../include/ -I../../model/ -I../../source/codegen/ -I../../source/builder/ -I../../source/example/ -I../../source/kshist/ -I../../source/dynov/ -I../../source/tasklib/ -I../../source/dbparse/ -I../../source/dbdump/ -I../../../../libml/ -I../../include/runtimeserver/ -I. -c ../../source/dbutil/ov_dbutil.c -o ov_dbutil.o
no errors or warnings
Add -Wl,--no-as-needed as linker arguments.
My issue was solved by adding -ldl in the lining line of the .so you want to link agains, it was called libov.so in the upper example.
I use MinGW to create, and my lua version is 5.1.4 the followings are my steps:
swig -lua example.i
gcc -c example_wrap.c -I C:\Lua\5.1\include
gcc -c example.c -I C:\Lua\5.1\include
gcc -shared example_wrap.o example.o -o example.dll
errors ocurrs at last step, here are some part of the errors information

example_wrap.o:example_wrap.c:(.text+0x2f52): undefined reference to `lua_rawset'
collect2: ld returned 1 exit status
it seems that I didn't include the lua header?
so I also try these commands but no use
gcc -shared example_wrap.o example.o -I C:\Lua\5.1\include -o example.dll
so any suggestions?
Try to link with this command:
gcc -LC:\Lua\5.1\bin -shared example_wrap.o example.o -llua51 -o example.dll
the path in the -LC:\Lua\5.1\bin part should point to the directory where you have your lua51.dll (I assumed bin, as in my system, but change it to suit your installation).
How to correct following error when I compiled test code written in C using credis API:

I'm busting my head for so long.
Thanks for solution.

Put the library after the source file that references it:
gcc -g -Wall test_redis.c -lcredis -o redisOUT
I am porting an application that I developed in Linux to Windows and am having some issues when building the application. After making the necessary code changes, everything compiles fine (and when built as a debug build in Visual Studio, runs without any issues). I need to build this in MinGW, and I'm having linker errors when I try to link it against liboauth, which is also required for my project.
The command and its output are as follows:

I have all of the required libraries in the lib path, and for some reason liboauth just cannot find the references to libssl and libcrypto. This all builds fine in Linux. Any ideas?
Update
Based on responses, I have updated my linker command so as to link the libraries in a different order. My new command is as follows:
gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto
This fixes this previous problem and presents a new set of linker errors:

A quick google search returned that I should also link in the gdi32 library (for purposes unrelated to my tasks. The final command for the linker is then as follows:
gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto -lgdi32
Try this:
gcc -o application application.o service.o util.o json.o api.o -Lc:/mingw/msys/1.0/local/lib -loauth -ljansson -lcurl -lssl -lcrypto
