Why GCC compiling went wrong? One step is btter than two steps?
Hi, when I was trying to compile a program to validate a SCEW lib, GCC prompted some strange errors... Could anyone pls give a quick shot? Thanks!
Compling&Linking in one command is OK, but after I separated it into two command it went wrong,,, [root@fileserver2 common]# gcc scew_print.c -L ./scew -lscew -lexpat -I ./scew -o kkk [root@fileserver2 common]# ./kkk Usage: scew_print file.xml [root@fileserver2 common]# gcc -I ./scew -c scew_print.c [root@fileserver2 common]# gcc -L ./scew -lscew -lexpat -I ./scew -o kkk scew_print.o scew_print.o: In function `print_attributes': scew_print.c:(.text+0x43): undefined reference to `scew_element_attributes' scew_print.c:(.text+0x53): undefined reference to `scew_list_data' scew_print.c:(.text+0x61): undefined reference to `scew_attribute_value' scew_print.c:(.text+0x6e): undefined reference to `scew_attribute_name' scew_print.c:(.text+0x8d): undefined reference to `scew_list_next' (rest of erro msg were deleted...) PS: libscew.a is compiled by " ar -rc libscew.a $(OBJS)"... |
After change the parameters order, it works! why?
I just changed the order of parameters it works! Why?
[root@fileserver2 common]# gcc -o kkk scew_print.o -L ./scew -lscew -lexpat -I ./scew [root@fileserver2 common]# ./kkk Usage: scew_print file.xml |
