i changed a line in a program that i have
.c file

now should i comple it again and put the .o file in the program folder or do i have to compile the whole program again ?

i.e is there special compilation options done when compiling a program or comiling a program is the sam as compiling its individual files ??

It depends on what you are doing.
Some programs come with libraries that they link static to, and several targets
depending on this library or file you have changed
some doesn't
in most cases running make'll handle this
if you change a .c file make'll compile that file, relink all the targets that
depend on it
to compile
gcc -c ffile.c -I/include/dir/1 -I/inc/dir/2
to link
gcc -o foo file1.o file2.o -L/path/to/lib/dir -llib1 -llib2

so i only should change the .c fiel and run make again and it will be fine ?


just make ??
this won`t affect the installed program after that ??

empty my inbox ? why!
i have one place for a private message :-)
ok, You have my mail :D

make'll compile the program, and rebuild any targets that depend on the .c file "if there is a Makefile". you'll end with an executable
to install it use: make install. and unless you make install, you'll not affect your previously installed copy.

ya3ny should it be make then make install ?

or just make ??
