Hello Hector, A part of the application to port to emdebian is a little led deamon. I start with that one and it simply consists of one C file. The header #include <pthread.h> is included in the C-file. To compile it I use this makefile: CROSS_COMPILE = arm-linux-gnu- AS = $(CROSS_COMPILE)as LD = $(CROSS_COMPILE)ld CC = $(CROSS_COMPILE)gcc CFLAGS +=-O0 CFLAGS +=-I/usr/include APP = ledd OBJS += ledd.o BLD_DIR=$(PWD) all: $(APP) $(APP): $(OBJS) @echo ' ' @echo 'Building target: $@' $(CC) -o$(APP) $(CFLAGS) $(OBJS) $(LDLIBS) A make in the project folder: hoe...@wks02-lin:~/projects/hasler/emdebian_eval/datr_led_daemon$ make arm-linux-gnu-gcc -O0 -I/usr/include -c -o ledd.o ledd.c In file included from ledd.c:23: /usr/include/pthread.h:653: warning: ‘__regparm__’ attribute directive ignored /usr/include/pthread.h:665: warning: ‘__regparm__’ attribute directive ignored /usr/include/pthread.h:710: warning: ‘__regparm__’ attribute directive ignored Building target: ledd arm-linux-gnu-gcc -oledd -O0 -I/usr/include ledd.o ledd.o: In function `main': ledd.c:(.text+0x139c): undefined reference to `pthread_create' Note a "cd /usr/$triplet/include" ends up in /usr/include. So I suppose the CFLAGS+=-I/usr/include is not correct. Do you have any Ideas how to proceed? -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
