Best regards. Hello thomas, thank you for your help, but acctually, I do not change the uml1.c itself, I changed in a text file that contains a set of c instructions and I include this file in my uml1.c So, if I do not reconfigure and make, the compiler will not compile the uml1.c again, it will keep the same uml1.o (with old c instructions took from the old text file). any idea ? I can not add to make coomand a list of files to recompile ? or can I add the c instructions of text.txt to my uml1.c using another way ? now I add in my uml1.c : #include "//home/charfi/Bureau/My_GCC/test.uml" to take into account the instructions of test.txt (a sort of copy and paste). thanks Asma
