I'm a beginner in the Database community. I have been trying to interface with MonetDB using C/C++ MAPI. I have installed MonetDB on my Ubuntu 14.04 LTS machine and when I try to compile a sample program from here, I get the following error:
$ gcc test.c -I /usr/include/monetdb -lmapi
test.c:(.text+0x29): undefined reference to mapi_explain_query'

This question has previously been asked here and the answer did not solve the problem (although the answer was accepted, I'm not sure why). Any help/directions would be great!
On Ubuntu 18.04 using:
pkg-config --libs monetdb-mapi and pkg-config --cflags monetdb-mapi
Won't work because Ubuntu doesn't have a bzip2.pc:
Here how it worked:
gcc main.c -I /usr/include/monetdb -lmapi -lssl -lcrypto -lstream -lcurl -llzma -lbz2

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.

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.

Something went wrong, but I don't understand what and where.
I still need a help.
Thank you.
Try this
arm-poky-linux-gnueabi-gcc video_1.c -o basic-tutorial-1 ` pkg-config --cflags --libs gstreamer-0.10`

I am trying to compile this lib on ubuntu 12.04 LTS
Help please
The issue was the shared library I was using was built with a different version of GCC. After I downgrade from Ubuntu 11.04 (from 12.04 LTS) it was resolved.
I have been searching for a couple of hours and found several threads with the same problem and tried all their suggestions.
My curl.h is in C:\MinGW\msys\1.0\curl-7.29.0\include\curl and I've included it at compile time but for some reason gcc claims it can't find it:
gcc -o curl.exe curl.c -IC:/MinGW/msys/1.0/local/ -IC:/MinGW/msys/1.0/curl-7.29.0/lib/.libs/ -IC:/MinGW/msys/1.0/curl-7.29.0/include/curl -IC:/MinGW/msys/1.0/OpenSSL-Win32/ -lcurl -lws2_32
and the result:
curl.c:4:32: fatal error: curl/curl.h: No such file or directory
UPDATE: (With the suggestion from H2CO3)
$ gcc -o curl.exe curl.c -IC:/MinGW/msys/1.0/local -IC:/MinGW/msys/1.0/curl-7.29.0/lib/.libs/ -IC:/MinGW/msys/1.0/curl-7.29.0/include/ -IC:/MinGW/msys/1.0/OpenSSL-Win32/include/ -lws2_32

If I try to compile with -lcurl it says ..... ld.exe: cannot find -lcurl is this because it can't find the dll?
You're including <curl/curl.h>, and not <curl.h>. So you have to tell the compiler to look for header files in the include directory, and not in include/curl:
gcc -IC:\MinGW\msys\1.0\curl-7.29.0\include etc. etc.
This might be beyond the scope of what you're doing, but, I found it best to install a version of cURL(libcurl) into the MinGW/MSYS environment. After installed, any program can be compiled to use it with the typical <curl/curl.h> and -lcurl conventions since it's installed where GCC would expect it. I documented my process here.
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
