When compiling your program  you need to include dict c as well  eg   gcc -o test1 test1 c dict c  Plus you have a typo in dict c definition of CreateDictionary  it says CreateDectionary  e instead of i

User · Answer

This issue appears when you have a running console at the time you try to run other  or the same  program  I had this problem during executing a program on Sublime Text while I had another one running on DevC   already

User · Answer

Your problem is the typo in the function CreateDectionary   You should change it to CreateDictionary      collect2  error  ld returned 1 exit status is the same problem in both C and C    usually it means that you have unresolved symbols  In your case is the typo that i mentioned before

User · Answer

generally this problem occurred when we have called a function which has not been define in the program file  so to sort out this problem check whether have you called such function which has not been define in the program file

sometimes this error came beacause  failed to compile in middlest of any build  The best way to try is by doing make clean and again make the whole code

User · Answer

I got this problem  and tried many ways to solve it  Finally  it turned out that make clean and make again solved it  The reason is  I got the source code together with object files compiled previously with an old gcc version  When my newer gcc version wants to link that old object files  it can t resolve some function in there  It happens to me several times that the source code distributors do not clean up before packing  so a make clean saved the day

If you are using Dev C   then your  exe or mean to say your program already running and you are trying to run it again

User · Answer

Go to Advanced System Settings in the computer properties Click on Advanced Click for the environment variable Choose the path option Change the path option to bin folder of dev c Apply and save it Now resave the code in the bin folder in developer c
