Thanks for the help, I installed zlib and gnat and can compile the
example code. Now I can call standard C functions in vhdl, but I can
not call my own functions. Can anyone send me a small example, how to
link my own *.c file in the Makefile? I tried to replace the call. package random is function rand return integer; attribute foreign of rand : function is "VHPIDIRECT rand"; end random; with my own method: package random is function rand return integer; attribute foreign of rand : function is "VHPIDIRECT foo"; end random; and I have written a small file (foo.c) returning an integer: int foo () { return 17; } I compiled it (foo.o), but I don't know how to link it to the work file. Starting the make process returns the following error: mar...@markus-desktop:~/Desktop/Beispiele$ make ghdl -a random.vhdl ghdl -e -Wl,-lm random_tb random.o: In function `work__random_tb__ARCH__behav__P0__PROC': random.vhdl:(.text+0xdf): undefined reference to `foo' collect2: ld gab 1 als Ende-Status zurück ghdl: compilation error mar...@markus-desktop:~/Desktop/Beispiele$ make ghdl -a random.vhdl ghdl -e -Wl,-lm random_tb random.o: In function `work__random_tb__ARCH__behav__P0__PROC': random.vhdl:(.text+0xdf): undefined reference to `foo' collect2: ld gab 1 als Ende-Status zurück ghdl: compilation error Sylvere Teissier schrieb: or sudo apt-get install zlib1-devit depends of the distribution try both...._______________________________________________ Ghdl-discuss mailing list [email protected] https://mail.gna.org/listinfo/ghdl-discuss |
