Simulink Code-Generation: 'undefined reference to...'

Hi Guys, I am using the Matlab Function Block to to write driver software to communicate with the TinyCAN I-XL Hardware, which is connected to my Raspberry Pi. In the Function Block I call to Wrapper functions "my_init_func" and "my_tiny_can_func". "my_init_func" again contains API-functions that are necessary to initalize the TinyCAN Board (e.g. "LoadDriver", "CanSetSpeed", ...). "my_tiny_can_func" again contains functions that write to and read from the can bus (e.g. "CanTransmit", "CanReceive",...). All this Code is written into a C-File "TinyCAN_read_Test.c". This C-File includes "config.h", "global.h" and "can_drv.h" ,which I copied into my Matlab-Directory in which the C-File is located. I also copied "can_drv.h", "can_drv_config", "can_drv_ex.h", "can_drv_linux.c", "can_types.h", "config.h", "global.h", "linux_util.h" and "mhs_can_drv.c" into this Matlab-Directory. I executed set_param('RaspiTinyCANDriverBlock','CustomSource',fullfile('..','09_TinyCAN_test','TinyCAN_read_Test.c')) to make sure, Simulink finds the C-File.
When I try to build the Simulink-Model with the Matlab-Function-Block, I get these errors: STDERR: TinyCAN_read_Test.c.o: In function `my_init_func': TinyCAN_read_Test.c:(.text+0x14): undefined reference to `UtilInit' TinyCAN_read_Test.c:(.text+0x1c): undefined reference to `LoadDriver' TinyCAN_read_Test.c:(.text+0x58): undefined reference to `CanExInitDriver' TinyCAN_read_Test.c:(.text+0x98): undefined reference to `CanExCreateDevice' TinyCAN_read_Test.c:(.text+0xe0): undefined reference to `CanDeviceOpen' TinyCAN_read_Test.c:(.text+0x128): undefined reference to `CanSetSpeed' TinyCAN_read_Test.c:(.text+0x140): undefined reference to `CanSetMode' TinyCAN_read_Test.c:(.text+0x150): undefined reference to `CanDeviceClose' TinyCAN_read_Test.c:(.text+0x158): undefined reference to `CanExDestroyDevice' TinyCAN_read_Test.c:(.text+0x15c): undefined reference to `CanDownDriver' TinyCAN_read_Test.c:(.text+0x160): undefined reference to `UnloadDriver' TinyCAN_read_Test.c.o: In function `my_tiny_can_function': TinyCAN_read_Test.c:(.text+0x264): undefined reference to `CanTransmit' TinyCAN_read_Test.c:(.text+0x2c8): undefined reference to `CanGetDeviceStatus' TinyCAN_read_Test.c:(.text+0x32c): undefined reference to `CanSetMode' TinyCAN_read_Test.c:(.text+0x354): undefined reference to `CanReceive' TinyCAN_read_Test.c:(.text+0x448): undefined reference to `KeyHit' TinyCAN_read_Test.c:(.text+0x464): undefined reference to `CanDeviceClose' TinyCAN_read_Test.c:(.text+0x46c): undefined reference to `CanExDestroyDevice' TinyCAN_read_Test.c:(.text+0x470): undefined reference to `CanDownDriver' TinyCAN_read_Test.c:(.text+0x474): undefined reference to `UnloadDriver' collect2: error: ld returned 1 exit status make: * [../RaspiTinyCANDriverBlock.elf] Error 1
When I put "api_calls.h" into my Matlab-Directory and add #include api_calls.h into my C-File, I get: Function TAR tried to add two files as "global.h".
Any help would be greatly appreciated, thank you!
